VOLKSWAGEN PASSAT COOLANT PROBLEM

2003 Volkswagen Passat • 136,000 miles

Can't find a coolant leak (yet). Is it possible for it to leak out of the turbo to gas passages?

Pressurize the system to see if you can locate the leak. If you still can't, they make a dye that you add to the coolant then check for leaks with a black light. It will glow when the light hits the dye.
