Hi,

My corsa sport temp gauge says its running too hot i.e it stays at 100 but doesnt go over that however the fan doesnt kick in either.
I've changed coolant temp sensor, radiator fan temp sensor, new thermostat (inc coolant flush, change)
new lamder sensor and spark plugs.
Is there a separate relay for the fan as if a short the fan it does work. Could this be a dodgy relay, or temp gauge not accurate of relay, where is it and what else could be causing it to run too hot (unless its right temp?) Any ideas? thanks

the usual tickover is 90-100 usually but the fan shud kick in still does it smell too hot ? have you tried putting a direct live to the fan just too see if teh fan works still ?

it does smell hot bit oily but just done oil change, i've put a direct feed to fan and it does work its not losing water and no leaks im not sure where relay is on fan could it be that?

i had same problem with mine changed as you have said turned out to be the thermostat was sticking and not allowing water to pass through rad properly give it a try there only cheap. hope you solve your problem

i've put new thermostat in already and coolant flush etc...

what about an air block mate try bleed the system

ill give that a go, i did take out the coolant temp sensor when filling and waiting till coolant starts coming out but there may be a few bubbles etc..

Its a self bleeding system anyway there should be no risk of air blocks..
Ive just fitted a temp gauge i got from scrappy because my gauge actually broke
Seems to be running too hot, like around a 100 but the fan kicks in and cools it.. any body know why it might be running hot?
