I want the cooling fan to turn on @ 210*

T&A-XJ · Oct 19, 2007

and not 220*+..

This is on a 96, has anyone tricked the PCM to read a slightly lower resistance (as to not effect the A/F ratio) on the CTS to make this possible? Adjustable CTS? Inline filter? ect?

For some reason I like the idea of the engine running 200-210 instead of 210-220+, must be because I am used to my 90 Xj running at 190* or so all the time no matter how hard I beat on it. Any ideas or am I wasting my time even thinking about it.

Thanks,

Tim

Put in an over ride switch & turn it on when you want. JIM.

Or turn on the AC or defroster.

or you could put in a temp switch and hardwire it to that

scroll down a little there's a list of like 20 thermal switches just for this purpose, thread in and wire. most are adjustable so that you can pick anywhere from 160-220

Or connect it to an aftermarket, adjustable switch/sensor using a separate relay...

Yea painless makes an after market adjustable sensor/switch.

My attempt at not using a second sensor/switch doesnt seem to be possible. If only the resistance value increased as the temp increased it would be simple.

Wiring in a manual switch would work but I am looking for something automatic that I cant forget about. Adding a temp switch is my remaining option, I just need to find a location for the sensor that I like.

Check out Summit or Jeg's - you can usually get an aluminum coupling for radiator hoses that has a bung - threaded 3/8"NPT (which is what most temperature sensors are threaded.) Problem solved - just cut about 2-3" out of the upper hose somewhere straight, and put that in.

Gives you about the same 'sense' you'd have with the OEM sensor in the thermostat housing anyhow.
