oil temp sending unit question

I noticied today that my oil temp. sender was broken and the wire had fallen off of the sender. I'm in the process of rebuilding this 2000 350 rancher 4X4 es and was wondering if I had to have the oil temp. sender to run the engine when I finish it. My understanding is that it just tells the fan when to come on, am I right? I read a thread were some fans rarely come on at all. The male spade on the sender just fell off. I wonder if I can just stick the wire in the sender and soider it in and that work, anybody done this before?

Yeah, the oil temp sensor tells the fan when to turn on and it also makes the oil temp light turn on when it needs to. It's important that the fan runs on those Ranchers when it needs to or it will got hot and melt the piston and rings. I have one in my garage right now and that's what happened to it.

You might be able to solder the wire to it, but it might get the inside too hot and the sensor might not work properly anymore. I think I would just buy a new one.

What happened to the Rancher that you are rebuilding it? Did the piston and rings melt? If so, then the wire breaking off the sensor is probably what caused it to do that.

Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

I traded a gun for it knowing it didnt have any compression. It was treated very rough with no care. I found it had a .75 piston in it and the oil ring was broke several places. Swingarm bearings are bad also.

I would also buy a new one. If you used a low temp. Solder it wouldn't damage the sensor but the engine would probaly get hot enough to melt it and then it would fall off again. A high temp. Solder will damage the sensor.

Just rig a switch to the fan so you can manually turn it off and on...

I was thinking and you can go to Radio Shack and buy a clip on heat sink that would let you solder it back on without burning the sensor out.

Can't you just ground the wire and then the fan would run all the time, don't know if its a normally open or closed switch.

I believe you are correct 69. I think when it gets a certain temperature it just grounds to the block to complete the circuit. He could tell for sure when he gets it running by just tipping the end of the wire to the block and the fan should kick on.

Most 4-wheeler problems are caused by a loose nut connecting the handlebars and the seat!!

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

I think thats what the manual says to do to check the fan operation, just ground that wire. So I guess it wont hurt anything to just run it for a bit when I get it back together and replace it soon after?
