Q: Car overheating but not a lot

asked by on July 27, 2017

So I've been having isssues with overheating lately. Took it to many mechanics but they all say different stuff. But I finally tried it out today and looked at it closely. My car starts up fine and idles perfectly at normal temp. I start driving and it's keeps cool and normal. But then I start idling or I'm parked the temp goes up to the middle of the middle line and 3rd line but doesn't go up more than that. And within five minutes it's right on the middle line. I've done a good flush, took the air bubbles out by taking off the radiator cap, new radiator, water pump is about 7 months old, thermostat recently at autozone, and cooling fan works.

My car has 235000 miles.
My car has an automatic transmission.
