    ok bew51861, how about the temperature switch, it's under the hood, passenger side, upper engine area, mounted in front side of water outlet. It controls the cooling fans, and could be the problem w/ your fluctuating temp gauge. Let me know how u make out.

  • Curt Downs Nov 17, 2008

    Did u check to see if the cooling fan(s) were operating properly?

SOURCE: temperature hand goes up and down

You could need to bleed the system of air. you should add coolant to the overflow bottle after you fill up the radiator and then let the car run until it gets warm enough to open the thermostat when your cooling system needs to bleed air and take in water it should let air out into the overflow bottle and take in coolant

R reg toyota previa over heats. had new pressure cap n tested the head gasket so both of them are fine. is it likely to be the water pump? as its worse wen Im startin n stopping but seems fine wen Im...


It appears that you have a viscous fan hub driving the fan or should I say failing to drive the fan. The fix is to replace it . If you have electric fans then there is a problem in the temp sensor system and the fans are not cutting in on temperature The problem you state is indicated by the fact that when driving there is sufficient air through the radiator to remove the heat from the radiator ..but when driving slow there is no air flow because the fan is not drawing air through the radiator and the temperature climbs until over heat is reached . Typical indicators of fan speed problem is overheating at stop sign/lights, slow heavy traffic driving, slow up hill driving, and rapid cool down as road speed is increased , the faster the speed the cooler the motor

My 2003 ford taurus overheats when driving around town, stop & go, but on highway temperature goes back to normal


I had the same problem with my 99 ford taurus. My ford taurus did exactly did same things that your vehicle is doing. runs cool on the freeway because the air is going through the radiator and cooling the water down.I checked the cooling fans, radiator and hoses for leaks also replaced my thermostat. nothing solved the problem. turns out that the new antifreeze does not come with a lubercant property any longer. you have to buy the lubercant additive separately and then add it to your cooling system when you replace the antifreeze. the lubercant protects your freeze plugs, water pump, radiator, thermastat from rusting out. Meanwhile because of the absents of the lubercant, my water pump impellers rusted out and dissolved. so the water pump had no fins to circulate the water. Luckly for me, I discovered that my car was still under warranty due to an extended warranty I had purchased when I bought the car. ford dealership replaced the water pump. Problem Solved.

Temperature gauge goes up down


this could be a clogged radiator or heater core, either way have your coolant system back flushed.

My 1995 Chevy Monte Carlo is sometimes running hot. My overflow tank remains full. But the radiator is losing water somewhere but I see no water on the ground or anywhere else. When I take the radiator...


indicates an air lock in the cooling system
could be from a failing head gasket ( do a compression test)
have a coolant pressure test done to find the leak
possible a water pump seal leaking when running
check sump oil for greying color ( failure of the housing behind the pump impeller

When you take your foot off the gas the temperature gauge goes up. We already changed the thermostat and the water pump. What else could it be?


Water pump does not sound like it because if the temp goes down when gas is applied that means water pump is pumping. but good to eliminate it none the less.
Possible cause
Clogged radiator
try to flush the radiator both ways
restriction inside the block

97 transport 3.4 engine- New radiator, thermostat,temperature sensor, water pump and new low coolant level sensor. Temperature guage goes to 260 degrees but engine does not over heat. Bled air from cooling...


Are your cooling fans working? that will definately be a problem if not working. if they are working shut car off and feel the radiator is it the same temp all over or is it hot in only top or one smaller area. if you do not have same temp feeling on all of radiator your radiator may be plugged.

99 cadillac seville continues to overheat even though i put a new water pump


maybe the water pump wasnt the problem to begin with. if the engine temperature only goes up when you stop the car then most likely it is the FANS that are not engaging to cool the radiator which is a problem with the fan sensor, computer that controls the fans, relay/fuse. I had the same problem on my 1999 cady STS coming back from my vacation. the engine temperature would be normal only when I drove the car above 70km/hr because the air passing through the front of the car would cool the radiator. when I slowed down the fans wouldnt start and no air was passing through to cool the rad, hence the engine temperature would start to go to HOT. good luck.

Toyota estima 2.2 td 1992 water temperature high


I had same problem, but when I got to top of hill and sat idle for a bit, it would kick down ? replaced thermostat and still happened until I dumped radiator fix for temperature problems, overheating and such and has not happened since, no problems but even when I know the engine has to be overworked and should show hot, it never goes past middle. I'm not sure of name of liquid, got it from a car dealer, but it is basic about $18.
