when should my fan kick in?

[ollie ryan]

my car has over heated twice now and it only does it sitting in traffic and i cant hear the fan on and have left the car to idle at home for about 10mins and the fan doesnt start up

dont want to damage my new engine so what do i need to do?

[Asad]

Have you recently removed the aircon?

Check all fuses/connections

Then replace the thermostat (sod testing it for the price and due to the fact youll be removing it anyway you might aswell replace it)

by now it should come on and run fine.......

[ollie ryan]

well i had the aircon removed just before the first japfest and it over heated on the way to japfest and then over heated the other day again but i never sit in traffic

i will check everything over and put my 4th thermostat in nowthen see what happens

[Asad]

have you bypassed the plug for when you remove the aircon (or is that just on GTs?)

4th one?

[ollie ryan]

i just took the ac out didnt no i had to do anything else

[Asad]

Have a search around i think? its just the GTs that need it done

also you said the 4th thermo? how long has this been going on? what have you checked and replaced?

[ollie ryan]

i had a new one with the headgasket

then it over heated so my second one

another with the new engine

and now looking like my 4th

will only be a second one from over heating but it hasnt over heated in 6months untill a few days ago

My fan is always on, as is my other mate with a GT

[ollie ryan]

yeah if your remove the ac from a gt something needs bypassing so it doesnt stay on the time

your fan shouldnt be on all the time mate you need to bridge the plug.

[Craig_T]

How/Where/what do I do that?

I didn't remove it myself, so have no idea what's what

[Guest cheshireglanza]

your lucky headgasket is holding out if its over heating all the time

[ollie ryan]

Well I don't let t over heat all the way as soon as the gauge goes up Past themiddle I switch it off but why is my fan not working?

[bucketep91]

theres a green plug under the distributer, make sure its connected properly.

[ollie ryan]

[ollie ryan]

cant just assume its a thermostat lol

Simple stuff to check first. Are both rad hoses burning hot? Are both matrix pipes burning hot? Is the top and bottom of the rad burning hot? Is there hot air from the vents? Have you put power across the fan to see if it actualy works? If the fan works with 12v through it id be looking at coolant temp switch ect.

cheers for the info

i will check it all this weekend and update this thread
