Electric fan control

[63comet]

If using an electric fan on your radiator what do you use to control it? I've had one of the thermostat things with the pill that you wedge into the radiator but I feel it's never been that consistent and it just failed totally on me so I need to replace it.

Painless Wiring has a kit that includes a sender and a relay and a circuit breaker. I mounted the sender in the thermostat housing after drilling and tapping the spare boss on the housing. Any available tapping up near the thermostat neck would work. Turns on at 185 and off at 170. They also have a sender kit with a different temperature range. Been in my car 10 years and no problems at all. If it does mess up all you have to do is pull the wire off it and run it to a ground and the fan will run. Speedway has them.

ive used the probe type adjustable switch i think your describing on a few different vehicles both at work and at home and havent had a problem with any of them. i think its the flexalite version.
are you using the adjustable switch as the only other component in the circuit besides the fan? the fan might be drawing to much amperage through the switch. you can try wiring a relay into the circuit, wire the ground side of the coil through the switch and wire the fan itself on the other side of the relay. the temp switch closes at whatever degrees you want, gives a ground path to the coil in the relay, that pulls the switch inside the relay and shoots 12 volts to your fan.
ps i carry a jumper wire in my glove box, just a length of wire with 2 spade connectors in case my switch ever craps out. that way your never stranded without a fan

I've used a tempurate switch from a Dodge Omni. Of course nowaday's I'm not sure how many Omni's are left in the wrecking yards, but I wouls suspect if you can find any of the early 80's Mopar cars that used a 2.2 or 2.5 engine they are likely very similiar. They are a simple two wire switch that are screwed into the head.
