Check them plastic housings for distortion ,or just change them ,they are only cheap anyway and very prone to leaks when hot and under load

I have a 2001 VW Beetle. I started the car and the engine light was blinking and coolant container was empty, added coolant and the next evening the light came on again. I noticed a leak on the front...


look for a leak from the drain hole under the pump housing, if no leak not a water pump
take the car to a radiator specialist shop and have a coolant pressure test done to determine where the leak is
if it has plastic tanks for the radiator , they split with time and leak under pressure and a pressure test will reveal exactly where the leak is unlike a guess

2002 VW Jetta 1.8T has a leak somewhere.Need diagram


Bring the car into a repair shop and have them pressure test it for leaks or you can purchase a pressure tester make sure you get the appropriate adapter for your cars radiator filler neck or resovoir, and check for leaks yourself. Make sure the car is cold and there is the appropriate mixtiure of coolant and water in the system, prior to pressure testing. Also do a visual inspection of the cooling system when the vehicle is cold and look for leaks.

Overheating


It's going to run hot, especially in hot weather but one big thing is what kind of coolant you are using. If it's dex-cool ( chevy and gm brand ) get it out of there and put some pre-mixed good coolant / water mix and it will help a whole lot. Just had the same problem with my 02' blazer. If the water pump and thermostat have been changed you should not be having a problem.

Oil in water resovour vw 2002 passat


This is probably a head gasket problem and not an oil cooler problem.

The oil cooler is fairly easy to test.

Remove the cooler from the engine but do not disconnect cooling lines and then pressurize the cooling system. You can use a radiator test tool to put pressure on the cooling system and look for leaks. If it leaks, replace it.

You may also be able to bypass the oil cooler altogether if it leaks.

The head gasket is another story.

Get a 1/4" pipe to spark plug fitting and put a male air coupling fitting in it.

Then you can charge the cylinders with air from your compressor.

Make sure each cylinder that you test is at top dead center so that the valves are closed.

If air bubbles into your coolant, you found your problem.

If air leaks out your intake you have a bad intake valve

If air leaks out your exhaust you have a bad exhaust valve etc.


If you find this useful, please take the time to rate it.

2001 VW Passat leakin water


I would highly suggest a pressure test to really pin point this leak. I can tell from diagram that the coolant expansion tank line goes right thru that area. I would also caution you to the obvious with this vehicle- everything is a tight fit and coolant leaking from the t-stat housing and or water pump could look similiar. I strongly suggest a pressure test to keep from throwing good money away.

VW Passsat - 98 -


ABS and coolant are unrelated unless there is a problem with the ECM (engine control module) or instrument panel. Is the red coolant warning sign for coolant level or temperature?

With ABS if there is any failure with any brake electronic component (sensor, motor, or fluid level etc) the ABS will shut down completely and flash the light. If the light is on or flashing the ABS is non functioning.

I need better information on the coolant and ABS to give better information.
