temperature gauge drops while driving

[2GturboTALON]

At idle i notice my car is a tiny hair under halfway on the temp gauge. Last night while driving i noticed that the gauge drops a little and goes back up. I replaced the t-stat about 3 months ago and also recently changed the coolant. What other things should i look at.

have you checked for any leaks coming fron around the waterneck,or where the hoses connect to the radiator.

Only leak i can find is an oil one from the oil filter housing.

well think about it, at idle stopped all that heat is in your engine bay and no air flowing through the radiator, when your driving of course it gonna drop cause the air is running though the radiator and cooling the bay the heat dont stay.

may need to look at the temp sensor if you think its malfunctioning.

well the gauge drops down a good amount, nothing that looks normal. Im gonna try a temp sensor i think though.

that means you have a loose wire or bad sending unit. it gets annoying doesn't it
