After replacing my water pump, gaskets, thermostat my car still runs hot. After starting it from cold, it runs up to about 3/4ths of the guage and then ticks down to between 1/3 and half of the guage. Which should be normal thermostat operation? Anyway after that it bounces around between 2/3rds and right before red. Depeding on the time of day, and how long I have to sit in traffic or lights. I hear the fan coming on from time to time, but doesn't seem to have any consistancy with the engine temperature. I've flushed it a few times with some cleaner autozone sells with no results. I'm thinking about taking it to jiffy lube or something to get it professionally done. Anyone seen this kind of problem before? Thanks in advance.
