Flex-A-Lite Fan Thermostat Placement

Hello.

I istalled the thermostat from my new flex-a-lite e-fan in the radiator fins in the upper edge above the fan shrould (you can see that on the pic).
But it doesn´t work very good in this position. When I stand at a traffic light the fan turns on at about 210 degrees. When I drive slow in the city the temperature goes up to 220 degrees and the fan doesn´t turn on.
I´ve the feeling that the thermostat turns the fan on because of the heat under the hood and not because of the heat of the radiator.
My probelem is that the A/C radiator is in front of the noirmal radiator. I can´t stick the thermostat through the fins on anoher place.

Where did you install the thermostat on your TJ? Got Pics?

Thanks!
nicolas-eric

i have mine setup the same way and i dont have an issue. except mine is setup on the other side of the radiator.

I would recomend going and picking up a spare thermo switch. Ive had one go out on me and i had to hot wire the fan in the mean time.

that´s what i do. the fan runs nearly all the time to bring the temperature down to 210 degrees. but i think that my problem is the dirty and muddy radiator. that problem started after i was in deep mud and after I forgot to clean the radiator for weeks.

does it have to be attached to the finns or can it be mounted to the bottom of the rad. is it possible to drill and tap a hole for it?

no in this case its designed for the fins. there are different ways to have the fan run automatically. one way is like you say, where you can put in a thermo switch that threads into the radiator.
