Wanting to no what the inlet and outlet ports for heater hoses on a chevy 350. I have a air gap intake with the the four water hoses 2 in the front and to in the back and of course the one on the water pump.
View 1 RepliesThe leak looked like it was coming from a heater hose. The individual I bought it from said he fixed it and it wasn't leaking the day I bought it. Upon driving it home...cranked the heat up and windows fogged, switched to defog with no luck. Added some coolant and still the same thing and leak began again.
It smells like antifreeze inside and fog has oily feeling when wiping it off the window. Got in on the lift and no luck seeing where it was leaking from, even with it running. My previous experience with bad heater cores is that it leaks on the inside and smells like coolant... is it leaking on the outside or is it something else?
It's NOT overheating or blowing any kind of smoke. Temp gauge read normal! It's a 4.3L, 1994 Caprice LS .....
Just replaced intake manifold gasket and valve cover gaskets - Put car back together and now it will 'start' but kills almost right away and the engine sounds like it is missing real bad - checked plug hook up of course. Was told we should not have moved the fuel rail (which we had). I think it sounds like the timing chain is off, but we did not touch that (according to my friend who did most the work).

If I hit a bump too hard the Check Engine light comes on because the gas cap pops out. Dealer told me this is a common problem with many of the Chevy models earlier than 2007. GM doesn't have a solution, either.
Since none of these cars have a locking mechanism I decided to get a locking cap at NAPA because the locking mechanism would hold the cap in place. Nope! The locking cap is even worse.
I have a 2001 malibu , my cars engine light has been for about a week. This is the second time it has happened. lately I have been having trouble starting my car. Does this have anything to do with my car , or because of the cold weather? How important is it for me to get my car checked out?
View 2 RepliesAfter filling the gas tank yesterday, as I was on my way to work, the check engine light came on. For the last couple of days the temperatures outside have reached 118 degrees. I have checked the oil and coolant and have resealed the gas cap as well, yet the light still remains. The research I have done leads me to believe the problem may be the catalytic converter, but I'm wondering if there is any further troubleshooting I can do without heading to a mechanic.
View 7 RepliesI have a 2010 Chevy malibu LT with 120000 miles. And today while I was driving my engine disabled and there was a message of reduced engine power. After letting it sit I turned the key and nothing happens all the lights and things come on but the reduced engine power and engine disabled shows up. The car won't crank up. Earlier that day I had my engine coolant temperature sensor replaced. What is going on or what needs to be done? I am getting so frustrated with this car.
View 3 RepliesMy 2003 Malibu engine will stop running all of a sudden while I'm driving. It has happened four times and I need to know why before the car kills me. The accelerator pedal goes limp and within ten seconds the check oil light comes on, the check engine light comes on, the power steering quits and then the engine dies. AAA mechanics had this car for four days and couldn't figure it out. My local mechanic has had it for five days and hasn't figured it out. I have looked on the internet and I am not alone. But there is no definitive solution to this problem. BTW, it's not the fuel pump.
View 7 RepliesWhen I tried to turn left yesterday, my car suddenly stopped with both the "check engine" light and "battery" light on, but the heat, headlights and radio were working just fine. I turned off the engine, and waiting a few minutes, ad then restarted the car, and everything is fine. I do not drive the car today. My question: is this a problem with the battery or the electric line? When the "battery" light is on, can i conclude it's a problem limited to the electric line only rather than a fuel line. My car is Chevy Malibu, 1999, with 90,000 mileages on it.
View 12 RepliesMy 2008 Malibu service manual states that the check engine light should briefly come on when I start my engine. When the engine is cold this does not happen. Also, it happens infrequently when the engine is warm. My Chevrolet dealer says this is normal as the light checks out when tested. Chevrolet has not given me a difinitive answer on this. My concern is that if this is a problem it may surface at another time when the light should go on and cause damage if not attended to. If the manual says the check engine light should go on when the engine is started and it doesn't, doesn't this mean something is wrong?
View 14 RepliesI have a 2006 Chevy Malibu 125,000 miles, 2.2 Engine that was running sluggish, noisy like needed oil (checked didn't) and check engine light was on. Took it to a repair shop and told needed an oil change, car still ran sluggish, told to drive it a day or so. Two days later, car wouldn't go over 50 mph, took it back and told needed air filter and mass air flow cleaned. After they did that, they told me the Catalytic converter needed replaced however they don't do that work. Within a week car would not run so had the cat replaced.
Car ran better but still not great. Took it to another place, spark plugs replaced, throttle body cleaned and fuel injector cleaner added to gas.Still the car ran sluggish and was making noise and check engine light was on. Took it to parts store to have code checked on check engine and said error in bank one of oxygen sensor. I replaced that, reset the light and am sure you know, it still runs bad and noisy and check engine light came back on. I am losing power on hills and big hills the engine rattles.
2000 Ford Expedition, XLT, 4WD, V8, 5.4 Liter. Had heater core bypassed, changed, am re-assembling, but need diagram for where all hoses connect on block, etc.
View 1 RepliesI've got a pretty substantial drip someplace at the vacuum heater valve and I am trying to figure out what I am dealing with. I replaced the valve and clamps but the leak persists. The three hoses are so close together I cannot tell which one is leaking.
What are the part numbers for the three hoses? There is one that runs from the intake/front passenger head to the valve that is just held on with clamps. One runs straight down to some sort of fitting and connects to a metal line. I think it may be a quick connect fitting. It is very short.
The third runs from the back of the valve to the firewall.
There is a fourth hose that comes back up from the "somewhere" below and also is a metal hard line with a fitting and rubber hose that goes "someplace" else back towards the firewall. Not connected to vacuum valve...
In any event, if I am going to rip into this, I'd like to just replace the hoses in one shot and done with it. No luck finding much on Google.
The 2 pics included show the valve and the front heater hose. ( I saved the OEM clamps by just sliding them back on the hoses as pictured. I figured if the valve and worm drive clamps didn't fix this I'd put them back on.)
I have been encountering issues with my heater not providing hot air when the engine is idling. My Elantra has around 121K miles on it. I have not replaced the thermostat, water pump, timing belt, radiator, radiator hoses, or done any coolant flushes.
I checked the overflow reservoir and radiator. I didn't see coolant at top of the radiator so I topped it off as well as the reservoir. It seemed to have fixed the issue for now but I had this similar issue about 5-6 months back. I also topped off the coolant and things have been fine until now.
I checked the hoses and squeezed them to see if I could see any notable leaks but didn't see anything. I checked the overflow reservoir tank and line and nothing seemed out of the ordinary. I also checked the top of radiator to visually inspect for any notable cracks but didn't find anything. Also to note, the coolant inside the overflow bottle was bright green and not discolored.
I did however notice a lot of white chalky residue on the bypass hose below the upper radiator hose and the engine block. My guess is that my upper radiator hose is slowly leaking? Leaking in the thermostat assembly? And I also noticed a tiny puddle of coolant below the lower radiator hose at the engine block. See the pics below.
I have a new hose I need to install because the one on now is cracked... I have pulled the metal clip down, but how do I remove this so I can install the new one? I don't want to break anything else yanking on it too hard.
View 5 RepliesHad a large puddle of coolant under my '05 X this afternoon after work. Seems it's leaking from the Y connection coming off the heater water control valve. See first pic.
I think it's part number 18472 (labeled with the circled 1) on left side in pic #2. Need to confirm this is the right part and the full part number?
Lastly, how the heck do you change this hose? It's tucked up under the cowl and looks like difficult.
98 F150 2wd 5.4 -even though VIN says its "W" 4.6; it has a 5.4 with 4.6 timing setup-found. But that's a whole other story...
So, Replaced heater core. did the blend door too.
A week later it overheated and blew a heater hose off the core at the firewall (several times). Temp was up and down, forced me into cylinder head protect mode, so i called my mechanic.
Mechanic used a sniffer (blue liquid turns yellow) in my overflow tank and there was exhaust gas in it... so we replaced head gaskets, intake, timing, water pump, radiator and the rotted out rad support.
Got it done and back on the road, but a few weeks later and the heater hose quick disconnect blew off again, spewing coolant all over (again). This was what we thought was part of the original problem- head gasket allowing cylinder compression into the coolant passages. the little rubber hose that comes from the back of the intake and goes up into the heater core builds enough pressure to pop the disconnect right off and I dont know why. Like I said- I thought it was the head gasket blowing pressure into it but that's all been replaced. Why the pressure would be so high at that point, and how do I correct this?
This is my daily driver, so for now I've bypassed the heater core, but I'm afraid that pressure is gonna burst a hose and/or fitting again.
I just wanted to share with you all about a coolant leakage problem I had experienced for a couple of days.
It all started a few days ago when I noticed the temperature gauge needle, which I hardly ever look at, began fluctuating in the hot region. I thought "oh my god" what is wrong? I then stopped at the nearest gas station and added some, I mean a lot, of water. My initial thought was the coolant level was too low.
The following day, I noticed the belts were squealing a bit (at that time I thought it was another vehicle with loose belts, but NO... it was mine making the belt noise). At that time, I did not realize it was because the coolant was leaking onto the belt(s). But then when I made a stop at a location for a couple of minutes, I returned to my Aerostar and noticed a trail of coolant leaking from underneath the vehicle.
I thought "oh my god" the water pump is busted! I then took it to a local repair shop and inquired about the cost to replace the water pump.
But after I inspected the vehicle more thoroughly, I noticed some dryed out green colored stuff where the heater hose connects to the water pump. I then removed the heater hose from the water pump and discovered to my surprise a tiny hole had developed where the hose is expanded from 5/8 to 3/4 inches.
My plan to repair the problem is to purchase about 6" of 3/4" heater hose (to connect it to the water pump), and a Gates or Dorman plastic adapter reduction fitting that reduces it to 5/8", in order to plug it into the factory original old heater hose.
This is an emergency repair. While inspecting the heater hose, I discovered an electrical connection that goes no where.
I have in the last 5000 miles had the timing belt changed and at same time the usual other item - water pump, Thermostat etc,, Engine has 155k on it.
I have had overheating issues that I thought was related to the viscous fan clutch and replaced that (it was bad) and the issue of overheating now just take longer to happen.
I have bled the coolant system and have good hot air out with heater - engine warms up within 1/2 mile of house. I am running right now Prestome all color antifreeze as it was overheating and and loosing liquid as a result.
In trouble shooting yesterday I find that when it now overheats it is leaking at the heater hose on drivers side of heater box. I have repositioned hose and clamp after bleeding it and it still overheats and with pressure build up leaks at this location - this happens when moving or when stationary.
With heat coming from heater box (both hoses get hot) and both fans working would this be bad thermostat? (again have heat) or a bad water pump?
What is the inside diameter of an '05 Escape heater core hose?
View 5 RepliesFound a tee on the heater hose leaks when it warms up. Appears the PO had noticed it but put a hose over it and now is leaking around behind the valve cover. This is a hard plastic line around 5/16. No online parts show it as being available. Is there a fix for this ?
I would bet several others have had this problem as it lays right on top of the flange of the valve cover where I think it would rub a hole pretty quick.
