Passat (B7) :: Loosing Coolant But No Visible Leak?
Nov 15, 2013
I started loosing a bunch of coolant on my tdi which is still under 36k and there is no visible leaks anywhere
Took the car to the dealer last night to get it checked out and they were ready to send me back home telling me there is no issue since they don't see any leaks under the car
Either way after telling them that I have already gone through 2 gallons of coolant they decided to top off the coolant and ask me to drive 200 miles.
I drove 156 miles last night since I need to get this issue resolved and now the coolant tank is empty again... sitting at the dealer while I'm typing this.

I've had to replace my radiator twice due to it overheating. I am noticing coolant level going down but I'm not seeing any signs of an external leak. My garage is saying it is probably internal and going into the engine. Says I probably have to replace the head gasket but that will be very expensive.
Could I get some further feedback on what it could be and what else I could do? I am also getting a check engine light on a "lean mixture" issue. Not sure if they are related.

I have a 2006 Jeep Liberty (2WD), 149k miles, that has been using a lot of antifreeze lately. I am using a full 50/50 gallon mix about once a week. I do not have any visible leaks. My heater no longer works and I was not sure if that may be a cause. The check engine light is on, but has been since I purchased the vehicle in 2012. I thought it may be a gasket, but do not see any white smoke from the exhaust. I am not hearing any strange sounds, so I am perplexed.

Our '03 Infiniti I35 lost large amounts of coolant each time on 2 long trips but when we did a pressure check, we couldn't get it to leak anywhere we could see and no visible signs of where it may have leaked while driving (no drip lines, puddles, etc.). We're not sure where the water pump is located, but have been told it's internal to the engine, so how can we tell if it's gone bad? Would the coolant burn off with no visible signs? We changed the radiator cap but no change. We use a trusted shade tree mechanic, but he's stumped.

Just noticed my level is about an inch below the full mark, it was fine at the last oil change, no leaks that I can see....nothing on the ground.

My 2002 has had a slow coolant leak for quite a while (maybe a quart a month). Now, however, I am losing over a gallon a week, but with NO visible leak!
The oil is clear, with no signs of antifreeze in it, so I am guessing the head gaskets are ok. But I am perplexed as to where my coolant is going!
After reading more threads in the forum, (which I should have done more thoroughly before posting,) it seems that I may indeed have a head gasket leak. From what I've learned, that would cause me to lose coolant through the exhaust while driving, and would explain why I don't see a visible leak anywhere. Am I on the right track? Before I replace the head gaskets, are there any other causes that may have a simpler fix??

I have a '98 Honda Civic with 230K miles on it. Last month, I suddenly saw few drops of coolant on my garage floor. I opened the hood and saw coolant splashed over the engine. I opened the coolant reservoir and it was empty. Surprisingly, the car never overheated and neither did the temp needle go up. I took the car to the mechanic (Honda shop) and they said that the radiator is leaking. I replaced the radiator and after driving for couple of weeks, the same issue re-occurred.
The coolant ran low in the reservoir and there was coolant splash over the engine. I took the car back to the shop and they said that the hose was not properly installed. They fixed it and said there is no sign of leak. I have been driving for a week now and check the coolant routinely. I have noticed that the coolant level has again dropped significantly. But, after the last fix, I do not see any visible sign of leak. There is no evidence of coolant anywhere under the hood. I am not sure if there is something else going on now. Is there something else I should check?

I have a 2000 passat tdi, over the past months ive noticed that I have been loosing coolant through my coolant reservoir overflow, my car has been running perfectly, my mechanic told me that its likely to be a head gasket problem and he put ceramic sealer in the coolant system, which was a disaster, the coolant pressure became much worse and told he me I needed a new radiator, which he fitted, but there was no improvement, whilst my mechanic was working on the car he noticed that when my car was running if he removed the oil filler cap the engine breathed heavily, my mechanic told me that the engine would need replacing,so I should sell the car as soon as possible.
I found it difficult to believe my trusty VW was in such a bad state, as it has only done 87000s mile and has full service history and starts and runs like a dream. Today I went for a second opinion, they told me that the coolant problem was because of a defected water pump, with most likely the plastic impellers failing, and the engine breathing problem could be down to a blocked breather at the top of the engine.

I am a clueless 2003 Volkswagen Passat 1.8L Turbo owner. My power steering line has a visible leak that I can see underneath the front bumper. The leak is now more like a hole and was caused by the line dragging after the car was in the shop. I guess someone bumped it or it got knocked loose, but at this point, I need to just get the line fixed. The leak is on a U shaped part of the line, and I can take a picture of it.
I also understand that the power steering fluid is not the standard type...where do they sell the kind I need?

I've had my R32 for a year, in that time the car has used a quart of coolant in 9K miles. Is this normal? No visible leaks.

I have a 2003 9.5 Saab with a 3.0 liter tdi. It has 160,000 km. The coolant light came on saying that the coolant was low, I took it to the Saab garage. They said that the ducts are compressing and that the water pressure increases in the engine and comes out of the radiator cap. According to them, it will eventually (within days or months) kill the engine. Saab does not make these engines anymore. I took the car also for an oil change which they say is not worth doing.
According to them, these engines have had problems like this (i.e. it is not a one off). We checked and do not see any coolant leaking from the reservoir cap but we see some coolant leaking on the garage floor. We check the oil and see no sign of coolant leaking into the oil and therefore do not think that it is a head gasket problem. We don't fully understand what the garage is telling us, is it a common problem ? How can we treat this ?

On starting today I had an alarm to check coolant. Never had this before - and the expansion tank was dry. No visible signs of loss - Oil seems fine and free from contaminant.. so I guess not the head gasket!

2007 Mini Cooper (Not the S model) burning coolant. Have brought to two mechanics and no visible external leaks. Both did a pressure test and was fine. They think the head gasket is blown. Car is operating normal.

I have a 2005 Cadillac CTS with a 2.8 V-6. I have changed the Mobil One oil when ever the oil life has hit 50% since the car was new. I have 122,000 miles on the car now. In just the past few months I have noticed the coolant level going down at a rate of about 1/4 inch ever week with no visible signs of any leaks. I have pressured tested the radiator and the test comes back with no pressure loss. I also am losing about a 1/3 to a 1/2 quart of oil ever week with no signs of any leaks or smoke out of the exhaust pipe. I drive about 600 miles a week. My son is a tech at the local Chevrolet dealer. He has looked over the car and can find no visible cause for the fluid loss.

I have a 2000 honda civic ex that I recently bought used. It ran fine with no problems for a good month then the check engine light came on and it started overheating. I could smell burning oil and see smoke rising from the hood. I checked the coolant and it was all out. So I filled it back up. Drove about 20 miles and during the drive when sitting idle the car would shudder and jolt around for a second, after about 20 miles I could see the coolant that I just filled up was all gone. I could hear some bubbling sound, all of the coolant had burnt away and was steaming. I did some research and it could be a blown head gasket, but I'm not sure and was seeking how to fix it or to clarify if it was a head gasket.

Ok 210k truck runs great except I am loosing coolant into #1 cyl. Ive owned the truck since 120k and it has NEVER ran hot not even above normal. I guess due to expansion it will even fill up the cyl nearly hydro locking it, no oil in water/radiator and no water residue in the oil either. I had the intake gaskets replaced thinking it may have been it but it came soon back. I really dont think its an head gasket, has there ever been reported problems with the intakes on these trucks? oh btw 97 2wd with 4.6. Even with coolant getting into the cyl it still runs great just a little white smoke.... I really don't want to replace the engine I think it has a lot of life still in it.

I have an Oct 2001 2.7 GLS which apart from the odd ABS Tone Wheel and speed sensor issues has been uber reliable and a real pleasure to own (I've had it from new).
We had a problem about a year ago when the wife didn't get the fuel cut-off when filling up and over filled the car resulting in fuel pouring out of the tank vent and down the fuel tank under the car but after a long drive that cleared up and has not happened again. Interestingly we didn't get any engine CEL's or have any codes turn up at all when checked by my mechanic.
Over the past couple of weeks we have noticed a very strong smell of fuel under the car around the fuel tank. I can't see any indication that there is a fuel leak but have noticed when filling up that the smell is very strong and as the car runs the fuel down the smell reduces to almost nothing.
Today I removed the rear seats and the fuel pump access panels to see if there was any seeping around the pump gaskets but couldn't see anything and the top of the tank around the both pumps was a dry as a bone. Using a torch I did however notice that there was a darkening of the fuel tank surface in the centre which I guess is close to the vent valve, part 311990b:
Or maybe is where the fuel vent pipe runs to?

My mate has bought a mk4 golf and it is loosing coolant. There is no obvious signs of a water leak the car starts fine, goes up to temperature fine, only time the temperature rises is when the car has to work harder. (going up hill) then returns to normal.
Left the car today for a couple of hours and went to check the coolant level and the system was still under pressure when opening the expansion bottle top. There is signs of rusty water around the cars panels where the expansion tank is located. Previous owner said that it used 4 litres of water on a 330 mile round trip. previous owner said it could be the head gasket but there is no cream on oil filler cap.
There is no sign of water leaking from the heater matrix inside the car.

I have a 1996 BMW 328is and recently it overheated on the way to work which is about 20 miles i pulled over let it cool down and now when i drive the car after about 5 minutes it starts overheating and is loosing coolant but i am pretty sure its burning out the exhaust now the person i had bought it from had replaced the head and head gasket no more than 8000 miles ago with thermostat and housing and water pump and radiator so now i get no heat in the car both upper and lower radiator hoses rock solid and burning the antifreeze.
