Two switches on the radiator. The one controlling normal running is scrap-replace both-front of the car must come off. Get an auto electrician to check wiring before assembly.

Also try wiring the auxiliary fan and any other fans so that anytime the vehicles motor is ON the fans are ON don't depend on a sensor on a Mitsubishi of that that don't come on soon enough, or stay on long enough, or turn on at all without letting you know until the motor overheats..... , are the leading cause of death for vehicles~!! lol

Waterpump not working?

Have you tested the thermostat yet? Are you "sure" it's working? That engine is NOT known for having water pump impellers going bad at all. I would believe a bad t-stat before a bad water pump. In my enperience if it's now flowing water, start there. If you can, take the t-stat out and put it in a pot of boiling water on the stove. Use a meat thermoneter, or even a cany thermometer and check the water temp. the T-stat should open up on it's own, even without water flow between 195 and 210 degrees. If it isn't, there's your problem. Start there, ESPECIALY if you "just put in a new T-stat." I've had FOUR bad t-stats brand new out of the box from 3 different suppliers in 15 days at my shop. I'm testing them before installing them now. the Stick

I put on a new clutch fan and do not know how to reset it to the thermos stat

Clutch fans don`t need to set, they just screw onto the water pump, the heat from water pump travels into it to turn it on.

Overheating problem. I have had my t-stat, belts, hoses, water pump, radiator shroud, fan shroud, fan pulley, fan bearing, and fan clutch replanced on my 97 BMW 528I. My car is fine for a while then it...

has it been bled correctly since all that work? Sounds like an air lock. Raise the front of the car as high as possible and chock rear wheels. Open bonnet, take off header tank cap and start the car. This helps any trapped air get to surface easier. No harm in also squeezing the hoses for a bit.

Engine overheating in traffic or when idling

I'm assuming your car has the Northstar engine?.

Strangely enough,if you remove the thermostat in the Northstar engine, it will overheat, this is because the stat is both a thermostat and a pressure valve.I can't be bothered to explain in detail how the whole cooling system works but please understand that you need to put the stat back in,(or preferably a new one).As for the cooling fans,what you described is normal for the Northstar.
Further to this, look at my profile,I have provided similar solutions for overheating problems.

New fan clutch t-stat still overheats

Yes, I am sorry to say this could be a blown head gasket. It could also be a bad water pump. Lets hope that it is the pump. You can get a pump replace for under $200.00 as opposed to the head gasket which runs over a thousand. It really sounds like water pump problem because you are not getting heated water to you heater core, where This would also cause the non mixing of fluids. Take the radiator cap off and see if you get bubbles rising to the to cover. Also if you rev the engine up and water comes shooting out the radiator cover hole the you definetely have a head gasket problem. Be very careful not to burn yourself. I bet anything it is just a pump. Gaskets ususally only go bad if you drive the car while overheating. Lets get this solved for you. Send me your qustions and we will get you taken care of. Please leave me good feedback, it means a lot to me....

Overheating engine in 24 valve 96 ford taurus 6 cyl

the thermostat can be easily changed from up top, the T-stat is located at the engine end of the upper radiator hose under the flange the hose connects to. Make sure u follow manufacturer's cooling system bleeding procedures when you refill after the T-stat is changed out.
