Is there a coolant leak in my TDI se?

2012 Passat Tdi SE with 153,000 miles suddenly developed a 1 liter/20 miles sized coolant leak (coolant level was fine at fill up 200 miles ago). Put the car up and removed the lower sound shield (belly pan) and oil pan insulation (both wet with coolant). Coolant is dripping off the oil pan after running down the front of the block.

Where is the coolant leak in my car?

Put the car up and removed the lower sound shield (belly pan) and oil pan insulation (both wet with coolant). Coolant is dripping off the oil pan after running down the front of the block. Leak appears to be in the area of the oil filter housing/oil cooler. Nothing above that is wet.

Is there a coolant leak in the intercooler?

I believe about 2L of concentrate is enough but not sure since intercooler also uses coolant. See your manual for capacity. Mix 50/50 or 60/40 with distilled water. I have confirmed that my 2013 Passat TDI SEL has a coolant leak in the intercooler. The car has 70k miles on it.

Why does my Audi engine keep losing coolant?

Coolant leaks are either internal or external.

Can a coolant pressure test show no leaks?

The coolant pressure test is obviously showing a coolant leak. The system should not lose pressure if there were no leaks. Since the leak is not external, it may be getting burned. Maybe the intake gaskets leaking again?

What causes coolant to leak from the radiator?

Coolant from the engine travels through tubes in the radiator. These tubes are surrounded by fins designed to direct airflow. The air cools the coolant, which then travels back to the engine, allowing it to run at the proper temperature. Radiators can develop leaks in several places.

What’s the best way to repair a leaking radiator?

Step 1: Locate the leak. Before you do anything else, make an attempt to locate the leak. There are many places coolant leaks from, so you want to make sure it is actually coming from the radiator.

For instance, over-filling the radiator can cause leaks from increased water pressure. A bad thermostat or a heater core can also create excessive heat and pressure on the radiator. Check the level of your radiator and the strength of your coolant while at the service station. Always check the radiator when the engine is cold; never while it’s hot.
