So my girl is driving from Radford to Virginia Beach. She drives a 2001 2.0 jetta. About half way there she says "she thinks" the car started to lose power and when shehit the gas the tach went up to 6k ( from what i could understand the engine did not rev but keep in mind i am on the phone, talking to a girl about a car, trying to get details). Anyhow, after that she said the car began to overheat. Any suggestions or common problems with this car that it could be. She said that when she went to check the coolant she pulled off the cap and it began to rise and the cap was extremely hot, so i am assuming the overheating is not just a problem with the guage.

Thankyou.
