99 camry 3.0 entire cooling system was flushed t-stat was changed this past summer but the temp gauge doesnt go up very much and the car take a while to heat up and even then its not hot. Was refilled with original OEM AF which the pink. any ideas before i reflush the system and swith over to the universal AF. Blower motor resistor was also replaced due to fan not working on middle speed.

 

Is the engine coolant really not getting hot or is the temp gauge off?

Is there a reason you changing the antifreeze type?

 

The interior heat is not hearing up like it used to do is tepid ady best. The gauge needle moves to just above the cold line when or should be near halfway mark. I can't imagine The coolant not reaching operating temp since The rebuilt system wad flushed out. No leaks I can see. The only reason im considering changing to universal fluid is to see if that helps any.

 

This problem has been going on since the summer?

Who did the flush and T-stat replacement work?

Low coolant temp points to a problem with the T-stat being too open.

Find a thermometer. Engine cold remove radiator cap. Make sure radiator has coolant. Start engine and let coolant heat up while checking with temp with thermometer. Should around 180F.

Changing coolant type isn't going to solve this issue. The coolant appears to be circulating too fast and not heating up.
