thermatic switch install...

[rob_w]

i have just installed a thermo from a n12 pulsar [its a good fit], and i am wondering if it is worth installing a thermo switch, or just hardwiring the fucker to the on switch in the ignition?

i still have the normal fan in there at the moment, but i wanna know before i remove the old fan.

on that, i also wanna know the best place for a thermo switch in a tg gem....dont be creative either, this really has me confused....do i use the heater lines, or the thermostat line....that kinda shit.

ok, thanks all.

if you install it to run all the time, it sort of defeats the puropse of fitting an electric fan, as it will load the alternator when running and sap your horsepower.

An adjustable thermal switch is about $40 from car shops.

BTW, you insert it into the top radiator hose.

ok...how?

its kinda dumb to ask, but i dont know a way of putting it in the pipe without it pissing water everywhere...or do i have to make a junction and t pipe setup in the hose?

thanks ben.

I think the switch comes with instructions. It has a small diameter (about 1.5mm) copper tube, that you put in between the outlet of the radiator and the hose. It comes with a little bit of rubber which you are supposed to use to stop leaks, but I just put a bit of silicone in their, and shes right!

By it, and then you'll get how it works. Without a switch, there is no benefit of using an electric fan.

I had mine wired up on ignition since I didn't want to risk the engine getting too hot.

Since my twincam has no engine fan at all (doesnt fit !)

I plan on getting one of these switches once I build the car back up though, seems like a good idea.
