The problem you seem to be having is the cooling temp sensor. It controls the fan speed which has two speeds. Try that.

I changed the radiator and thermostat on my 1988 acura legend but still overheats what can be causing the problem?

mixture of the radator fluidThis answer is possible but it is not correct and is a poor choice. There are a number of reasons why a car's engine overheats and the original question doesn't give enough information about the car and its overheating symptoms to deduce the answer to being a mixture of radiator fluid. It's not a good way to answer at all other than it being a guess.The engine can overheat b/c the radiator is old and fill with rust/dus particles that clog it up and the engine as well as the hoses. It can overheats if there's a cooling fan and it's not being turned on at lower speed (bad relay switch or fan motor). It can overheat if it's low in coolant or that the water pump is not working well. It can overheat due to a bad/broken head gasket. It can overheat with trapped air in the cooling system that needs bleeding. When driving with AC on uphill for extended period of time, it can and prob. will overheat, etc. Many reasons for the overheat and to simply give the answer of mixing radiator is simply naive and dull. Do more research being being trigger happy with the fingers :)

Cadillac 1996 deville overheats driving fast?

when overheating occurs at highway speeds the cause is usually. a radiator or coolant circulation problem, Check for a restricted or clogged radiator.

Why does my Chevy Venture overheat when idling but is fine when driving?

Check coolant level Cooling fan working? Dirt or clogged radiator? Defective radiator cap?

Why would a car only overheat when driving on highway not when driving around?

Could be debris (leaves, rodent nests, etc.) blocking the air flow through the radiator.

check you water (coolant) level, make sure thermostat is working, radiator leaks, sensor problem

radiator plugged.or coolant low

Why does 1987 Cadillac overheat when idling?

It could be a bad fan clutch. If the fan clutch goes bad it could cause it to overheat while idling, but it would cool off when driving due to the wind going over the radiator.

Why does your car overheat at idle or in slow traffic BUT NOT WHEN IM DRIVING AT NORMAL SPEEDS?

Make sure the radiator fan is operating properly. You should also check your coolant your radiator might need flushed or it may need burped

Why does your 1989 Chrysler new yorker only overheat when driving but not when just idling in one place and the fan switches on and off correctly?

A likely cause is an internally restricted radiator.

Why would a 1996chrysler overheat?

Driving slow for a long period of time on a very hot day. Or the result of another mechanical issue (such as the failure of the radiator fan or the fan belt).

Why my car almost overheat when air con is on or when its in hard acceleration driving?

Could be,Low on coolant.Cooling fan or fans not operating correctly.Coolant circulation restricted (blockage inside radiator).Sticky or stuck thermostat.Air circulation through radiator restricted (blockage outside radiator).

Why your BMW 320i 1983 might never overheat when constantly driving on Motorway but when driving through London city stop-start it gradually gets hotter and hotter until it goes into the red?

Low coolant? Cooling fan not working? Radiator plugged or air flow restircted? Defective radiator cap?

What could be causing a car to overheat when driving but not while sitting idle The radiator cap and thermostat have all been replaced and you have no known system leaks But you still have a problem?

Clogged radiator, bad water pump, defective fan or fan thermal relay.

You have an 1994 ford tempo and have replaced the thermostat and water pump and it continues to overheat periodically and run out the over flow?

The cooling system has probably been compromised with radiator solder seal or radiator sealant. After the vehicle is warmed up, use your hand to carefully feel the temperature of the air flow through the radiator. It should be warm all over. If there is a cold spot, then there are plugged portions of the core. Since it only overheats periodically, the cold spot may be relatively small. If you can detect the overheating event while driving, turn the heater on full to cool it down. If this trick works, you definitely do not have sufficient radiator function.

Why does the engine in your 1994 grand Marquis keep overheating?

I do not have a Grand Marquis so my engine does not overheat! Fords and Ford products tend to overheat and always have! Let's check a few things. How long has it been since you changed the thermostat and the coolant? Those two things are the most likely culprits. What is the condition of the hoses? Have those been changed in the last several years? If you have changed the hoses, the thermostat, and the coolant, and it still overheats, then it is time to take it to a radiator shop and have the radiator rodded out. ========================================================== I have been driving Ford models for over 40 years and have never had an engine overheat . Don't forget the basics , engine cooling system level etcetera . Check for a fan clutch problem , a problem with the water pump not circulating . Ford also states that if you exceed 60% antifreeze in the distilled water / antifreeze mix that it could overheat in hot weather

Why would a 1996 dodge grand caravan overheat if sitting in traffic with ac running but cool off when you turn it off or start driving faster?

The radiator fan is not working,or not working properly,or possibly the thermostat is bad.But,usually if the thermostat is bad the engine would still overheat even if you speed up,so I would suggest testing the radiator cooling fans.

My 1999 Jeep Grand Cherokee's radiator is leaking. Will I damage my car by driving it locally?

A leak can turn major in a hurry. If it overheats just a little too much it will ruin the engine. Have it fixed as soon as possible

Why does your 97 Toyota Camry over heat in traffic?

Usually car that only overheat in traffic have a radiator fan that does not work. It will not over heat while driving because their is enough air flow.

What causes a Saturn to overheat?

Check the cooling system, and I mean everything. Thermostat, temperature sesnor(s), radiator clogs, radiator cap, badly damaged water pump, belts, you could simply need to add more antifreeze. If it isn't your coolant system, then it's your driving habbits or driving conditions, in which case you may want to slow down, get a car that can handle harsh driving, or upgrade your radiator. Also check that your electric fan is coming on.

Why does car overheat when thermostat works?

Probably it has either run out of coolant or the cooling fan is broken. Some large engine cars in really hot weather need a larger radiator fitted so it doesnt driving a v8 around town in the summer in Spain for instance.
