I have a 2003 Pontiac Grand Prix engine size 3.4. My car is having a problem where the temp gauge will go almost to the hot area and then drop back down. When I am driving on freeway 60+ it stays a little above 160 and does not move only when I slow down or idle when it goes up to hot. My merchanic has changed some small part in back of the manifold which help for about a month. Has a lot of brown guke in raidator. Merchanic pressure tested it and says there is a leak. My question is since I don't have money to fix now what can I do to buy time now? Can it be the water pump? I am afraid $750 merchanic is asking for may not fix right problem.
Thanks for you help,
have the same problem?
