| I drive a 2003 Volkswagen Passat. Yesterday I was | | | | needs to be done is a "cooling system pressure test" |
| making a long trip home and about 20 minutes into the | | | | this will determine if there is a coolant leak in the |
| trip the car said it was overheating. The coolant level | | | | system. You want to check the coolant level INSIDE |
| was fine, and as soon as we would pull over the | | | | the radiator, not just what is in the plastic jug on the |
| temperature would drop back to normal (before we | | | | side of the engine.This car is pretty new still, is it under |
| even got to a complete stop.) Later in the trip it | | | | warranty or are there high miles? Since you mentioned |
| stopped cooling down when we would pull over and | | | | that it ran hot while you were driving, and as soon as |
| there was a sort of popping/gurgling noise that | | | | you pulled over and slowed down the temperature |
| sounded like it was sort of behind the dash.Took it to | | | | returned to normal...my first thought would be that there |
| the mechanic today and they have cleaned the | | | | is lack of coolant circulation. Low coolant level can also |
| radiator, checked the head gasket, etc. and they are | | | | cause lack of circulation, so make sure the radiator is |
| baffled.Any ideas? Hi there, The VERY first thing that | | | | FULL. |
