Original proof of purchase is required. I would test it and there would be no leak, but the coolant would somehow escape somewhere. I also disconnected the plastic pipe that comes out of the turbo, on the right side when looking at it, and there was sign of coolant. This is going to be a little long, but bare with me! No leaks, no milky oil just sweet steam out the tail pipe. I have done some research and see it is a very common and recalled thing with the heater core and I had no idea I hope us breathing this in hasn't done any damage I have a one year old who has been in it this whole time as well. Cheaper than testing with coolant.
I believe it was fairly inexpensive and was done in one day. Since I didn't know where to look anymore, I put everything back together on the engine and took the car for a drive. Here is a pic where i was looking for it to come out where the coper pipe is pointing to. It was sitting for 2 weeks and had a coolant mixed with what seemed to be oil leak under my car. Both outer cv boots were replaced.
I have read online on many sites that there was a recall regarding this matter and the owners were never notified. That is until yesterday when my wife told me the coolant light had come on. . The vehicle was also overheating. The heat in the vehicle was not working properly.
And previously I took off the engine plastic cover underneath. She received a recall notice, but the vehicle was not repaired according to the recall. Only once did the engine temp really start to climb. Im thinking to take of the turbo exhaust on the left side of the turbo and pressure the system again and see if it comes out there? It is fine if idle but once your driving everything starts beeping and when I'm turning you hear a noise on the side that your turning!. The only thing that comes to mind on this one is the thermostat may be partly plugged with that leak stop gunk now or could it have been placed in there backwards?? In many 2004 Passats, an anti-freeze leak can cause the temp sensor to record high engine temperatures.
The contact stated that her vehicle was a lemon when she purchased it in 2002. Shows how much the tech knows. I will post the second quote and repair details later. Problem is: The car has been loosing coolant since I've had it. I have had to replace the inside computer already and probably all the carpet since the water has been leaking into the car. Then put it underwater and bubble test it with compressed air.
If you ignore a small coolant leak long enough, you will run out of coolant, which leads to an overheated engine and other serious, but highly avoidable, problems. The headlight tail light and fog light bulbs were replaced. With it becoming immediately cloudy, I lost visibility of the cars in front of me. The approximate failure mileage was 174,256. Again now that I know it was unhealthy to be breathing the toxic smell. Unfortunately there were no visible signs of coolant leakage.
I will have to bypass heater core to stop this until repairs can me made. The hardest part of the install was getting a few of the hose retaining clips back in place. After exiting the vehicle, the contact noticed flames coming from under the hood. The problem was completely fixed after a new Serpentine Belt. The hardest part in the removal was getting the small coolant hoses to break free.
The failure mileage was 500 miles. I suppose there could be other areas gummed up by the leak stop as well. I took it by a vw dealer for a drive by diagnosis, it was confirmed it was the heater core. Commercial, heavy duty, custom, or off road vehicle use voids the warranty. Since I started testing, I did not want to start the car to see if there is a leak on any of the pipes or such. Follow the intake manifold down and you'll see that big metal box with coolant hoses coming out of it. The check engine light illuminated and the coolant bottle had a hairline crack.
If you are losing coolant via a head gasket leak that quickly, you should be seeing some white smoke steam out the exhaust pipe. There was a large evap leak at the purge valve which was replaced. Dashboard panel lights out odometer, fuel gauge, etc. The dealer diagnosed that antifreeze leaked onto the electrical wires. I have driven a few days and two or three times it will begin to overheat, other times it will not but the heater is intermittent, sometimes hot, sometime cold, and often alternating on a given drive. When i got the car i know its going to come with a leak guy told me before i bought it.
