Ok so I replaced the radiator, timing belt, and water pump on my 1997 TL 3.2 and after a few days my temperature guage begin to rise. It looked as if the car was going to over heat but then the gauge when because to normal. It only does this when I begin driving ?(within the first 10 minutes). What could be the issue?

 

A very common problem, just bleed the coolant system thoroughly.

 

Jack the front end up and bleed the system.
