Temp Gage while on local streets seems okay. When I take it on freeway within. A few mnutes Gage is at. Red like its. Overheating. Although. Cars performance seems the same. Check under Hood radiator a bit hotter than norm. But everything seems alright

The first thing I would check is the fuse associated with these fans. If that is ok then I would suspect the temperature sensor that controls the fans.

If temp gauge is going into the red on a 3.4 engine it must be shut down or head damage can happen within minutes. I have a Monte Carlo that was overheating. I changed everything, thermostat, water pump, belt tensioner, radiator, all with no result. It would start out okay on a cold start but then I would come to a red light and the temp would creep up. Higher and higher until it neared the red zone. The heat would run cold. Most of the time, as soon as it was about to touch the red it would start to drop, the heat would blow hot again and all seemed okay but not for long. This would get worse and worse until the red hot light came on and I found myself on the side of the thruway. This problem is a blown head gasket. I had no other obvious signs, no white smoke from the exhaust, no oil in the antifreeze. I even changed the intake gaskets. Head gasket issues are common on the 3.4 liter engines.

check for a blown head gasket, do a compression test on all the cylinders, they should all check out to about the same , if 2 are off you have a bad gasket

Two things come to mind, after each refilling of coolant did you "burp" the system to make sure there was no air trapped? And second, you may want to have the coolant checked for exhaust gases in case there is a headgasket leak into the coolant.

Please solve this problem, my car COROLLA 1988 automatic 1.6 has the same problem!!!!!

Be very careful as overheating can cause permanent damage to the head gasket.Now whenever an engine temp reaches half then the fan should start,so watch if this is working.Allow engine to run and watch the temp gauge goes up..Once it is half then the fan should start, if it does not replace thermostat..Else watch the radiator as it may be blocked.

you need to install a lower temp thermostat. and check the timing too far advanced will also cause this problem

If it gets hot at high speed such as freeway driving, but seem okay at street driving, It is the radiator. If it gets hot really quick at any driving condition, it could be the thermostat. Since there is no leak, the last possiblity, and also least likely is an extremely retarded timing. Lastly any kind of leak will cause an overheating problem, but from your info, it don't have a leak.

i think if a wire that is + on the gage and it is making contact with the ground it will do that.

POSSIBLY A FAULTY THERMOSTAT
