Grand Prix :: Overheating But Temp Gauge Not Going Above Normal Operating Temp
I have a 2004 Grand Prix and it is displaying the symptoms of overheating but the temp gauge is not going above normal operating temp. I replaced the thermostat twice, and after driving for about 10-20 mins coolant comes out of the overflow. I'm at a loss, I'm thinking temp sensor(?) But I don't want to keep throwing unnecessary money into it. The fans work fine, the heater blows as it should.

View 1 RepliesNissan - Altima :: 1997 GXE Stalling When Engine Warmed Up To Normal Operating Temp
I've got a 1997 Nissan Altima (automatic, GXE). Recently it has started stalling. Usually this happens when the engine has warmed up to normal operating temperature (though last night it happened when the engine had just started).
Usually when it stalls it will start right back up, but sometimes it takes a few minutes. Sometimes it will start back up and die right away, other times it will turn over and over but not start. After a few minutes it will start back up. Sometimes it will stall momentarily and then restart right away, but not usually.
The rest of the time the car runs smooth as ever, no surging, no stalling, no erratic idling, no sputtering or anything. Usually the check engine light will come on after a stall, but I get a "no code" code when I check.
This started about two weeks ago, it did it once on a Saturday and then didn't do it again until Wednesday. Since then it has happened at least once a day, and yesterday it happened a lot while I was driving home, but not at all when I headed to work. Today it was fine for about 15 minutes and then started doing it a lot, but the last 3 or 4 miles it was fine again.
What may be the problem? I'm going to check the MAF and throttle position sensors, though I would assume if they were malfunctioning I'd either have more symptoms or I'd be getting a code.

View 8 RepliesMontana :: Coolant Leakage Only At Operating Temp And Under Pressure
2003 Pontiac Montana 3.4 L
225000 Kms
Intake Gasket replaced already at 60,000 kms (yes a while ago)
Recently, noticed a major external coolant leak at the front of the motor (passenger side). It only leaks when at operating temperature and under pressure. It does not leak when you first start the engine, it takes a while before it leaks.
I replaced the rad cap, just in case it was faulty. Upon the second test, after getting it running good and hot, it leaked again. But only when at operating temp. It is not overheating.
Problem is, as the coolant is leaking out, the main drive belt is splashing the coolant all over the place and thus I am having a heck of a time pinpointing if it is a head gasket or intake manifold leak or perhaps somewhere else.
I can't take things apart to get a better view, because it needs to be running at operating temp to get the leak. If I pull anything apart for a better view, I won't be able to start the engine to reproduce the leak.
Passat (B6) :: Air Condition Only Works When Engine Is At Operating Temp
2006 Passat 2.0t. With the engine cold, the a/c will blow warm until the engine gets up to operating temp and the rad fan kicks on. After that, it will stay on and blow cold all day. I would think the rad fan should kick on as soon as I turn on the a/c to get air flow moving across the condenser as in every other car I have ever owned.
Does rad fan kick on as soon as you turn on the a/c? I'm thinking that i might have a problem with a relay that suppose to kick the rad fan on. I used my VAG.com software and its showing no faults.

View 1 RepliesFord - F150 :: 1994 - Idling Slightly Unsteady / Coolant Temp Reading High Normal
1994 f150 with 4.9L I6; 180k mi.
Parked vehicle last night after using it uneventfully for work the day before. Upon leaving the house at 11:30 AM, I noticed that I'd picked up a new mechanical noise. Nothing major; actually wasn't sure I heard anything at all.
As I drove to the store, I noticed it was idling slightly unsteady...much less so than a missing cylinder. I resolved to check the high-tension connectors when I got home for security. I glanced down at the gauges to check and see if my oil pressure was good; I then noticed coolant temp reading "high normal."
When I got out, I noticed a small pool of coolant forming. I looked at where the puddle was forming...the radiator hose had come off! (Actually separate from the radiator connector, as one might do if draining fluid without using the petcock.) I popped the hood: no unusual smells. Nothing seemed abnormally hot. Placing a finger against the head was uncomfortable, but not painful. Spit expectorated upon the head did not sizzle.
I then called my wife, explaining the situation, and walked back home 2 miles. We then took the spare car, bought antifreeze, and added it about an hour post-shutdown. Where the car was parked seemed wetter than the light drizzle allowed; daubing a finger in it and tasting gave a slight sweet taste.
I tend to check my fluid every so often (not every day, though) and coolant was verified as "full" as recently as 100 miles ago. (I don't make a habit of crawling underneath, though, so I couldn't tell you if hose had been slowly backing off or not.)
As to cause: is it plausible that this could happen without foul play? There have been a few vandalism incidents in the neighborhood; it's also possible that I [peeved] off a neighbor recently. I'm not about to go any further than fixing, though, unless there's really no other plausible explanation.
As to the mechanical questions: How much damage was done? Did I "catch it" in time? What is suggested as far as repairs/maintenance? (I was planning on doing a compression test, and keeping a close eye on fluid levels over the next 1,000 miles or so.) Engine sounds completely normal.

View 4 RepliesIntrepid :: Won't Start Up When Engine Is At Normal Operating Temperature
Sometimes, when the engine is at normal operating temperature, it won't start up when I turn it off. For example, let's say on my way home I stop off in a supermarket to pick up some stuff. I'll come back out 20 minutes or so later, only to find out my car isn't starting. I'll turn the key and the engine will crank, shake and then immediately die on me [I'm under the impression the engine isn't even starting at this point because tapping the gas does nothing]. Again, this is a problem that is only happening sometimes. I can do the same routine tomorrow and it'll start up flawlessly.
1) This is only an intermittent problem. The problem doesn't seem to be occurring more frequently, but when it does happen, the engine is harder to start. For example, the first time this happened to me, I got it started after one or two tries. After my latest episode, it took me 11 tries to get it running!
2) After the engine does finally start, the engine will run really rough and shake a lot until I tap the gas a few times (which is leading me to believe this is some sort of fuel related problem [sometimes, the engine will start on one try, but will run rough until I tap the gas a few times]).
3) When the car is cold, it starts up flawlessly every time without fail.
4) The car runs mint! No hesitation or otherwise stalling, etc.
What I've done so far to try to remedy the problem:
1) Changed spark plugs
2) Fuel line cleaning/flush
Camry :: XLE V6 - Tapping Noise When Engine Is Not At Normal Operating Temperature
I have a 2003 Corolla with 178K miles and a 2007 Camry V6 XLE with 30k miles. Both make a tapping sound when the engine is not at normal operating temperature (when the engine is still cold during the morning). I've changed the oil regularly on the Corolla with 5W-30 oil every 5k miles. I'll be making my first oil change on the Camry in about a 1 week.
The tapping noise goes away once the engine gets warm. Is the tapping noise normal? I don't hear this noise from our Honda Odyssey, which uses 5W-20). Can using a different weight oil work?
Golf/GTI VI :: Difference When Checking Oil Level At Normal Operating Temperature
I went out and checked my engine oil level when the engine was cold and the oil level was near the bottom of the hash marks. Drove the gti for around 15 min and fully warmed the engine and waited five minutes and rechecked the oil level. to my surprise the oil level was actually higher! it was now at the top of the hash marks. if I added oil when the engine was cold I would've over filled my engine. I always thought it was the other way around with a cold engine all the oil would have drained back to the oil pan and should read higher when cold. Why the oil level reads higher when the engine is at normal operating temperature?

My wife has noticed that the car seems to take longer to reach normal operating temperature than it used to (close to 15 minutes of driving). Other than probably diminishing the gas mileage and having to wait longer for nice heat is there any down-side to this problem? Is it likely to get worse and fail altogether? The shop guesstimates it will cost around $150.00 to replace.

Phaeton :: Surging Of Engine / Momentary Loss Of Power At Normal Highway Operating Speeds
The primary electric fuel pump in the fuel tank of my 2004 W12 failed last month, shortly after I had set out on a cross-Canada trip from Vancouver Island to Toronto. The whole process of diagnosing and identifying the cause of the problem, mitigating it so that I could continue the trip, and finally replacing the fuel pump was kind of complex, so, here's the write-up.
The problem presented itself as a surging of the engine - a momentary loss of power - at normal highway operating speeds. The onset was progressive, but it didn't take very long - only about 60 miles of driving - from the first little cough of the engine until total failure of the pump. The first indication was failure of the car to maintain speed (while on cruise control) when climbing hills. That progressed to failure to maintain speed on flat surfaces, and finally led to the car coasting to a stop, engine stalled, at the side of the road.
I soon learned that if I floored the accelerator pedal and held it against the floor, the car would cough and burp for a few seconds, then take off like a rocket. So, for the next 40 miles, I coaxed the car into the next city by flooring it, accelerating to about 80 MPH, then coasting until the speed dropped to 20 MPH, and flooring it once again and accelerating to 80 MPH. Fortunately, I was on a remote road with few other cars, and no police.
I checked the fuses for the two fuel pumps - fuses 34 and 35 in panel C (above the left battery), and they were both OK.
The next day, I visited a VW dealer in the Canadian Rocky Mountains, and together with the parts manager and one of the technicians, we looked at the Self-Study Guides (SSGs) for the Phaeton, and looked at wiring diagrams. Eventually, we came to a tentative conclusion that the primary electric fuel pump in the fuel tank had failed. The SSGs stated that the primary electric fuel pump (the pump on the right side of the car) operates all the time, and the secondary electric fuel pump (the pump on the left side of the car) only operates during starting and during 'periods of high demand'. That made sense to us - the car started fine, and worked OK when the accelerator pedal was held to the floor (high demand). It just didn't work worth a darn at any other time... the engine would stall, or, the car would not accelerate at all.
Here are two illustrations taken from the SSGs that describe how the fuel delivery system works. The first image is taken from the 'Phaeton Overview' SSG, which applies to all vehicles. The second image is taken from the W12 engine SSG. I kind of suspect that all the Phaetons operate in the same way, regardless of engine, because the fuel tank in all the Phaetons has the same shape - two lower lobes, which means two pumps are required.
Descriptions from the SSGs
I think that there may be an error in the description above. My experience suggests that the right hand pump (identified as G6, above) is the primary pump, and the left hand pump (identified as G23) is the one that switches on during starting and periods of high demand. Note also how the identification of G6 and G23 in the illustration above is reversed from what is shown in the illustration below. I believe that the text and illustration below is correct, and the text and illustration above is incorrect.
The 'effects of failure' in the description above would, I believe, make sense if it was the left-hand pump that failed. In my case, the right hand pump failed, and the effects of failure that I experienced were as I set them out in the beginning paragraphs of this post - quite different from the 'effects of failure' of the left hand pump that are described in the SSG above.
After coming to the tentative diagnosis that the primary electric fuel pump (the right hand pump) had failed, we checked the parts stock status in North America. There was one pump in stock, but it was in the United States, and being that it was a Thursday, the pump could not be delivered before the following Tuesday. I didn't want to spend that much time waiting for it, so, we started thinking about other possible solutions.
If we could somehow get the secondary electric fuel pump - the pump on the left side of the car that only operated during starting and heavy demand - to operate, that just might put me back on the road again. So, I removed the plastic cover from the small relay that operates the secondary pump, and wrapped a rubber band around the relay, thus keeping the relay in the closed position. A short test drive proved that this solution worked just fine, the car once again operated normally. The only "problem" was that the last 25% of the fuel in the tank would be unusable, because that fuel would be left behind in the right-hand lobe of the tank - the lobe with the defective primary fuel pump.
Electric Fuel Pump Relays
Here is an illustration from the Phaeton wiring diagrams identifying the various relays above the left battery.
Here you can see the two relays for the electric fuel pumps. They are identical part numbers.
Here you can see the relay for the secondary electric fuel pump, with a rubber band wrapped around it to keep it continually closed.
Aside from the loss of use of the last 25% of the fuel in the fuel tank, the car worked just fine with the secondary electric fuel pump running all the time. There were no problems noted even under heavy acceleration. It was, however, necessary to physically remove the rubber-banded relay from its position in the relay panel whenever the car was shut down for more than half a hour. The power to this relay comes from Terminal 30 (battery direct) - it is not switched on and off with the ignition as Terminal 15 power is. This meant that if the rubber-banded relay was left in position overnight, the left hand battery would totally discharge, because the fuel pump would operate continuously all night. I discovered this the morning after the first night...
So, for the next 8 days, I drove across Canada, removing the relay each night and replacing it each morning. I didn't bother to remove it when I stopped for meals or fuel. The rest of the 3,000 mile trip was uneventful - except once, when I let the fuel tank run down a bit too close to the 1/4 full mark, and the car began surging again because the left hand lobe of the fuel tank (with the functional secondary pump) had emptied out. That was a close call, but I managed to get to a gas station and refuel.
After arriving in Toronto, I called the parts staff at my home VW dealer and ordered a new primary electric fuel pump. I discovered that the left and right hand pumps are slightly different (the various hoses coming out of the pumps are different), and I also discovered that a pump costs about $400. The parts staff suggested I order two seals (one for each side of the tank), because I would have to remove both the right and left fuel tank covers to change the right pump. The seals were not expensive.
Here are two pictures that illustrate where the pumps sit in each lobe of the fuel tank. Note the fuel filler port on the left side of the pictures (as we know, it is on the right side of the car) for orientation.
Phaeton Fuel Tank, showing pumps
Fuel Pump Access Panels
Below is a picture that shows where the access panels to the two fuel pumps are. It's easy to get to these access panels, just remove the carpeted panel from the floor of the trunk.
Here's a close-up of the right side (primary) electric fuel pump access panel.
The instructions (from the VW Repair Manual, or the ELSA / ErWin system) for replacing the fuel pump are quite well written. The repair manual suggests that the fuel tank be drained before replacing a pump. I didn't want to drain the tank, so, I ran the fuel level down as low as I dared (remembering that 1/4 full is effectively 'empty' with a failed primary pump). That proved to be adequate.
There are a heck of a lot of steps involved in disconnecting all the hoses and loosening the various components before the pump can be removed. I strongly suggest that anyone attempting this task have a printed set of instructions before starting disassembly.
The fuel pump has quite a few hoses and connections on it, but fortunately, each connector is unique in design, thus it is not possible to hook things up the wrong way when installing the new pump. It is possible to 'lose' a hose inside the tank... for this reason, I attached a small piece of string to each hose I disconnected from the pump.
The process goes more or less like this:
1) Remove the two 404 relays, to ensure no power is sent to either fuel pump.
2) Lift the rubber cover, and remove the electrical connections from both pumps (left and right).
3) Using a special tool, lift up the three fasteners that hold the cap over top of the access panel (these are NOT threaded fasteners!)
Here is a side view of the three fasteners that hold the plastic cap in place - they are friction fit, not threaded.
4) Now you have a clear view of the access panel. It will probably be dusty and rusty, and should be vacuumed clean before proceeding, to prevent crap from falling into the fuel tank when the cap is removed. The rust is due to condensation forming on the cold metal part whenever the car is filled with cold fuel from an underground storage tank.
5) A special VW tool is used to remove the locking ring from the access panel.
6) After removing the locking ring, I buffed it up with a wire brush to remove surface corrosion.
7) The plastic access cap can now be lifted. There are two electrical connectors on each fuel pump, but three possible fittings on the plastic cap. Fortunately, the three fittings are keyed differently.
8) This is what you see inside the tank after removing the plastic cap.
9) After following all the detailed instructions for disconnecting and stowing hoses, disconnecting the fuel measurement probe from the pump housing, etc., it is possible to lift the pump out. It will be full of fuel.
10) The old and new pumps, side by side. I was very surprised at the amount of crap that was trapped in the filter screen at the bottom of the pump. The car only has 60,000 miles on it, and I have always used premium fuel in it.
11) I was also a bit surprised at the discolouration of the pump components. Below you can see the old and new pumps side by side.
12) It is necessary to get access to the opposite side (in this case, the left side) fuel pump, because hoses from each pump travel horizontally across the tank and connect to the other pump.
13) Here you can see a new hose from the right side pump connecting into a T fitting above the left side pump. It is easy to thread this hose across the top of the inside of the tank.
14) As mentioned earlier, there are three possible fittings on the base of each plastic cap, but only two connectors within the fuel tank. Everything is keyed, thus improper assembly is not possible.
Once the new pump has been installed, the hoses connected, and the fuel measuring probe reset into the side of the new pump, re-assembly of everything is quite straightforward. I replaced the rubber ring around the access panel opening on each side of the tank, and I also buffed up the locking rings using a wire brush (to remove corrosion) on each side.
It was not a pleasant job - your hands get covered in fuel, and there are some hazards associated with working on an open fuel tank with vapour escaping, but it is not a particularly difficult job. It is time-consuming, though.
