Passat (B5) :: Oil Or Antifreeze / Coolant Leaking Underneath - Loss In Power
Oct 20, 2010
So, I have a 2003 Passat Wagon GLS with a 1.8T and 110600 miles on it...
Here is my dilemma... I try and change my oil every 4.5 to 5 months and the passat has been running like a champ, but recently noticed the car was beginning to sound like a diesel engine and we were starting to go through the coolant..
Throughout this entire time my gas mileage seemed to have improved and I never noticed any oil or antifreeze/coolant leaking underneath, and it wasn't until recent that we noticed a loss in power.
My wife had checked the oil and noticed a yellowish/rust-like junk on the dipstick, as well as the dipstick not registering any oil... We also noticed the turbo was whistling during hill climbs.
We still have about two months until a required oil change is needed, but when it comes to mileage we surpassed it.

2002 7.3, losing coolant. Occasional whiff of antifreeze, not in oil. I use my truck to tow a food trailer that's only about 4500lbs, some highway, most city driving. 173K clicks, bout Jan 2016 with 130K, first time this has happened...

I have an old 83 datsun pickup. It is my first car and I love it and it has more character than most people that I know. one day it just started leaking antifreeze. I looked under the hood and could see a steady leak way down on the bottom driver's side of my engine. What's the problem and how can I fix it? No matter what, getting rid of this car is not an option.

The last week or so, the coolant level low light has been coming on in my 04 Touareg V6, and I've noticed that it is leaking underneath the car. I've been keeping a close eye on the level, and filling it back up until I could get it into the dealer. They can't get me in until the 24th, so when I was under it last night changing the oil I checked it out.
It is dripping from a round plastic piece on the firewall with a square "knob" on it. This "knob" has what looks like a cross indented into it. It was dripping slowly while the car was on, and continues for a few minutes after it's been turned off. I originally thought it was the a/c condensation dripping off, but it's definitely antifreeze.
I fear that it's the heater core and that it is leaking from the inside, but I could just be paranoid. It should still be under warranty (34,000 miles).

I have an 02 passat with about 85K and the other day my windows would not clear up and a faint smell of antifreeze. also when temp control is in cool and you move the temp control to warm steam comes out of vents. I need to know if i could change this myself and if any procedure on how to do it.

I can't see any leakage underneath. Could it just be the heater core? And if so, is it a pain to fix?

I have a 2003 Chevy Malibu, V6, 3.1, auto, 140k miles. Car started out with code 0420 with no noticeable symptoms, but then added code 0303 (miss fire cyl #3) with loud knock (mostly after warmup) and loss of power under load. Now internal loss of coolant (no puddles or external drips). Changed plugs and wires - no change - all plugs looked good with no sign of contamination. Questions - if this is a valve/piston/lifter problem (which would explain the knock, miss-fire and loss of power), why would I get the loss in coolant? If the loss of coolant is fouling plug #3 (which would explain the coolant loss, miss fire and loss of power), could that give me the loud knocking? I don't see how a valve/piston/lifter issue would cause a leak in coolant but I also don't see how a coolant leak into cyl #3 would give me such a loud knock. Do I have two different problems? If it is a leak into cyl #3, is there any way to tell if it is the intake manifold gasket (which leaked before and was replaced five-six years ago and which I could do again if I had to) or a blown head gasket (which I don't think I could fix or afford to get fixed)? Engine will occasionally get hot (but not overheat).

I am working on my buddy's 1994 Ranger with a 2.3L I4 that has been going thru a large amount of engine coolant. The trucks has approximately 180,000 miles on it. When I had it parked on concrete I have not seen any signs of coolant on the concrete or any signs of coolant leaking. The next place I checked was inside the cab to see if there was any coolant from the heater core and there was not. The water pump has been replaced a couple of years back. I replaced the spark plugs today and did not see anything on the plugs that I would have thought were signs of coolant in the combustion chambers.
With that being said I have not worked on a vehicle with a leaking head gasket before. Would there be any visible signs on the sparks plugs? If so what would I be looking for? When standing in front of the vehicle with the engine running there is a slight smell of antifreeze being "vaporized". Are there any noted issues with this engine that would cause this? Are there any other things I should check? Could it be a leaking head gasket causing this? If so how can I check for that?

Had my oil changed on my 2011 F350, and the tech said that I lost one gallon of antifreeze coolant. Where could the coolant have gone? We could not find a radiator or hose leak. I am afraid that the coolant somehow got into the engine oil, and may have damaged the engine. I have 46000 miles on the truck.

On Sunday my son was driving my wife's '03 Passat GLX 2.8 4motion station wagon when he received a "stop engine" warning and noted the temp was climbing past 250. Good lad that he is he stopped immediately and noted much steam and coolant originating at the rear of the engine. My hope is that it's just a hose since there is no coolant or smell in the interior (just went through the nightmare of a heater core on my '96 Jetta!) We had it flatbedded to our home but I haven't had time to make a further investigation and was hoping for some insight from those here as to how I should proceed in diagnosing/repairing this issue.

I'm fairly certain I'm leaking coolant. Below will be a pic of the reservoir as well as where it appears to be coming from. I did a search and saw it could possibly be a flange that may have failed? Other than that there wasn't much useful information. The screw in the picture was the only thing wet, and was directly above the small puddle on the garage floor. As you can see by the pic the coolant is visibly lower than last time I checked.

How to identify this 'leaking' coolant hose? (cooler hose?), I took a picture with my cell ... It shows a stainless steel coolant line with calcified Dried/heater coolant residue on the outside, and I noticed it was leaking coolant (using a periscope mirror )...

I can see where coolant has leaked out from underneath and come out the sides of the motor beneath the intake gasket.. probably a bad definition but yall probably know what i mean.. i know its a common 3100 motor problem.

2012 Prius C
Starting a few days ago, I noticed a wet spot underneath the front-right of the car.
Turns out, I'm losing wiper fluid. I fill it up to the top, watch it for several minutes.. it doesn't move. Pull off, come back 5 minutes later and I've lost nearly half the tank... so it's leaking, or at least leaking worse when the car runs by way of something calling for it or the movement of the car.

I recently had an upper radiator hose bust and ever since I have been having a slight water leak. It appeared to be coming from between the layers of rubber on the new hose which I replaced twice since the incident. Both hoses had water seeping from the same location. This afternoon I plan on doing a pressure test on the cooling system to diagnose where the water may be coming from.
My question is could a loss of pressure cause larger than normal Oil and Water deltas? If I have to replace the radiator is there a particular manufacturer or type I should avoid? Should I try to get a factory replacement from Ford or would an Autoparts unit be sufficient? The original is still in the truck now with 286,000 miles on it.

I have a 2000 suburban and it's leaking anti freeze but not going on the ground not sure where the leaking anti freeze is going to. it started out with no heat I, with my dad replace the cabin filters and got front heat back but after awhile I lost heat only in the front I have rear heat. not sure what the problem is? I am afraid to take it to a dealer and get scammed. it's not over heating or getting hot, but in the winter when it first started it i doled hard and it sounded like something was wrong with the lifter?

I have 3400 engine in 2000 alero (V6 of course). Been having problem with my antifreeze leaking, So I assume the lower intake gasket again(which I have already replace 6 years ago with no problem) but this time after I replace it I notice coffee color oil (antifreeze getting in the oil). So figure I must have done something wrong so I replace the lower intake gasket again making sure I tighten everything with correct torgue. Still the same problem, if not worst. I took the front valve cover off (because I didn't see any coffee color from the back valve cover last time) to see if I can see where the antifreeze is coming from, I can see the the coffee color oozing on the top of the 2 center pushrods and rockers not quite from the gaskets itself (from what I can see) and white steam coming valley (or between the two heads)and notice bubbling on the bottom (not sure if that is normal). Not really into replacing the head gasket, but before I do, I want to make sure first.

I am trying to figure out the problem with my 2002 ford 7.3 Engine.
[URL] ....
It has a lost of engine coolant. The oil is 100% clean with no signs of Coolant. No chocolate milk effect. Also it makes a Odd thumping noise at idle. I think it is coming from the Exhaust Manifold.

So I have a 2003 6.0 king ranch w/ 164k on it.. EGR delete, high pressure oil pump, coolant filter and SCT tuning. A couple months back I had a coolant flush done. After about a week the coolant tank was empty.. Engine heated up due to loss of coolant.. I flushed system again and put ford gold coolant back into the tank. (5 gallons). A couple days later and coolant was very low and engine heated up?? There are no signs of leaks anywhere...Added water and it cooled back down. I'm lost. EGR is deleted but no studs done.....

Last thursday night my wife said she had no heat in her car (03 gx470). I didn't know what to do so on Friday I did some research at work. On Friday my wife drove the car to work and back. Before she left work I asked her to look at the temp gauge and she never noticed it going over normal temp. On Saturday morning, I checked the radiator and it was practically empty so I drove it 3 miles to a shop to have them diagnose the leak problem. while in front of the shop I noticed antifreeze leaking from the radiator so I drove the truck home without them doing anything. Temp gauge never surpassed the middle.
I drove the truck home with the intention of replacing the radiator but I can't get the part until tomorrow (Monday) so to save time, I drained the radiator and pulled it out. I got less than 1/2 gallon from draining it. The coloring was red and green, which made me think tranny fluid and coolant but it wasn't milky and as I thought about it I recall when i did the 90k service with my bro (former toyo mech) the blocks where never drained so I'm guessing that I absent mindedly mixed green prestone with toyo coolant. Probably the reason my radiator is leaking?
After taking the radiator out, I didn't drain the coolant from the block valves, but I think it would be good to do that just to get an idea of whether or not its empty.
This morning i was thinking i should do a full flush after i replace the radiator, but since it would be impossible to open the valve on one side perhaps a flush isn't the right thing to do. Not sure if I should do a tranny dump and fill.

2000 Lincoln ls v8 ... I just replaced degas bottle and cap. I changed because it was leaking antifreeze. Now even with new bottle after I turn car off antifreeze is still coming through degas bottle cap. I was wondering if my problem could be my water pump going bad causing the fluid to boil after engine is shut and building pressure high enough to push through cap?
