I am not sure how high the gauge is going when a/c is on ? When you turn it on the fans should turn on as well. The condensor is a heat exchanger for the a/c . It will always raise the temp but the fans should turn on with the a/c. I am sure you have checked coolant level and that it is okay. If the waterpump impellers are bad this can cause a poor cooling condition. If the radiator is clogged it can cause it. as well as a thermostat staying closed to long.

Why does my temp gauge rise to hot when the van is off - but as soon as the key is switched on it goes back to the cold end of the temp gauge


The gauge is unpowered when you turn the key off, so the needle can go wherever it wants to. When you turn the key on, the gauge gets power and will show the actual engine coolant temperature.

Temperature gauge goes up down


that is a strange one , i think the problem is with the exterior temp sender as the fan cutting in and temp gauge falling is what you'd expect ,try diconnecting the exterior temp gauge ,may be a fuse for it ,if that is all ok i'd get the ECU checked as may be getting a short let me know how it goes

If the cooling system is functional, yes.
The ac condenser adds heat to the air coming thru the radiator when the ac is on. If the engine cooling system is weak, the extra heat will make the engine run hot.
Low coolant flow thru the radiator is a common cause.

When stopped at a stop light my oil gauge goes down and my temperature gauge goes up on my 94 Chevy 1500 truck. I just changed the oil yesterday? What could it be?


Both issues could be normal to a degree. The engine temp would go up some when the truck stops moving, and the oil pressure would go down some when the engine returns to idle.
Are the two gauges reading out of normal range ?

fans came late on those car,like 212 and second fan comes on at 224,you reprogram it to come a lot sooner,,other thing is there might be gunk inside the block,and coolant has hard time to pass through,and staying longer than enough in block temp goes high,even tough the radiator is doing it's job,it is just coming out block lot hotter than it suppose to be,and gauge read the block not the radiator

When the temperature outside is hot and I'm running the air, the temperature gauge starts moving into the hot zone. If I turn off the air, it goes back to normal. I've had it worked on several...


make sure that the coils, ( the ac radiator ) are clean , blow them out with an air hose if you can get a hold of one, also, make sure the ac fan is coming on, it may start , but the sensor may be bad allowing it to turn off too soon , a normal rise in heat is expected when using the AC but if it is too hot you should feel the motor start to run rough, if its running fine, and the temp does move back to normal when the ac is turned off, and a qualified mechanic has checked it, your probably ok, you could have a sensitive gauge, , If the normal range of the gauge moves to hot and back during normal driving without the ac on, that would show the thermostat is also working

1998 ford expedition: engine ovr heat light comes on- soon after heater goes from hot air to cold. Pull over cycle key all lights go to normal soon after heater goes to working. replaced radiator- fan...


Have you tried replacing the overflow tank cap. These don't hold pressure as it should which will cause the temp to rise. EX: the cap rating is 15psi, and the cap has a defect which only allows the cap to hold 10-12psi. That water has to be pressurized by the cap for the water not to flow out. Also, does the temp gauge reach a high level or just the temp light comes on. This will give a better idea of the problem. If the gauge is normal but the light is on, sounds like a temperature switch is bad.

My Cars temperatue gauge is


the rad must run as soon as AC is put on ,some cars have a pressure switch that put the rad on when the gas pressure in the ac system goes up with temperature ,cheapest way round this is to connect fan via a relay to the ac pump feed so as soon as ac is turned on fan comes on
