Radiator wires

[popup]

Hi i have a tb42 there is 2 wires that go in to a bolt on the side of the radiator just under the fill up neck. Can anyone tell me what they are for as my wires have broken off. Any help would be great.

Hi
I can't say 100% but generally this would be a temp sensor of some sort, I've dealt with a few on cars with electric fans and the fitting as you have described acts as a switch to turn the fan on/off depending on temp although I would expect your TB42 has a viscous fan? If so it could be to turn the A/C fan on at high temps?

X 2 with above or a low coolant level alarm.

Yes that is the one. I had a look in my Gregorys work shop manual and it does'nt show it. Thanks
