Q: temperature gauge on 2002 Mitsubishi Galant

This problem started about two months ago. When you start the car, the temp gauge goes to about 1/2 between hot and cold. When you first accelerate it is okay for awhile and then it creeps up a little. The temp will start to creep up when you are idling and comes down again a little when you start to drive. The car has been in the shop 3 times for this same problem. It has a new radiator, water pump, hoses, the sensors have been checked and it has a new thermostat. Any idea what the problem could be?

to be honest, it sounds normal to me. when idling, it will heat up, then the fan will kick on and drop the temp.
normal running is about 1/2 between cold and normal. under a load, it may heat up a little but fans will turn on and cool it back down.

did this just start?? has it overheated?? is this a change from the past??

I'm. sorry. I guess I forgot to indicate that the car runs hot. Iss it normal to go straight to 1/2 when you first start it and then less than mins be up to between 1/2 and 3/4 hot? The fans also work.
ok, makes sense. i suggest you get a cylinder leak down check on the cylinders to verify that you are not burning coolant from a head gasket or cracked head. i would start there to verify your motor is in good shape.

OK. That, too, has been done. That's why it is so odd that it has not been able to be repaired yet. I guess I will have to get a diagnostic.
that would be a good idea. have you had it to a shop?? if so, i suggest another shop with another opinion.

It has been in the shop 4 times for the same thing. Hopefully the diagnostic will give us a positive answer.
Thanks for your help.
