I wonder if any of you can help me. My STI 6 RA seems to be overheating alot as the fans seem to be kicking in all the time.
I drove home from work this morning(5 miles) at 40mph roughly and when i arrived my water temperature was reading 92 c(on the Power FC commander) and the fans were on.
I did put my heaters on whilst driving and found them to get warm very quickly also.
Could this be Thermostat related? Or even Water Temp sensor?
Any help would be greatly appreciated.

 

Have you checked your water level?

It could be something simple like an air lock or your end tank on the radiator maybe leaking as so many do on classics.

Fans come on at 91 and off again at 89... 92 is normal for sitting in traffic etc...

obviously check the water level, and if you drove at 40 and didn't queue in traffic then there is a problem somewhere.

Water level seems fine and it was a continuous journey this morning.
I will have a look at and test the Thermostat.
Thanks for the help so far guys.

 

drop the thermostat in boiling water and see if its open

 

After finding where the thermostat is i`ve decided to order a new one.
Will change it on Thursday and go from there.
Thanks again everyone.

 

Can you please let me know if this works as i have a classic wrx and have the very same problem..! but i've only just had a ENGINE CHANGE done at essex scooby breakers and has been fine for 3 month's (1200 miles) but i have no hot blowers.. =( i've been told it's not he head gaskit but i dont really know engines myself..!!!

Sounds like a definate air lock!

Even with a knackered thermostat u should get hot heaters

U need to take the cap off the water header tank and keep squeezing the bottom radiator water pipe until it starts to take water.

Top up the header tank and keep squeezing till it stops taking the water. You should finish up with the water level about 1cm from the top of the cap hole.

Yeah i did try this but it didnt work even tryed back filling from the heater matrix pipe i did get hot air for about 30 min then back to cold and the bottom rad pipe is always cold..??? When it get hot i likes to blow the water out of the over flow bottle next to the rad..! It not good =( It just doin my nut in now...!!!!!!!

And your are 100% that it is not a head gasket issue?

The thermostat is the obvious next step. You could just take it out and run it without to see if your heaters work, this will also give you the chance to test the thermostat in a pan of boiling water

Craig

 

well that is what i've been told..!! i'll try the pan of water. thanks bud i'll let you know.! =)


Ginger. =)

 

Will be having a go at changing my Thermostat tomorrow.
Will let you know how i get on.

 

Removed my theromstat and found it to be cream crackered!!
However, the replacent i was given was the wrong size.

I now have no thermostat at all but my overheating problem has been sorted.
Need to source me another one.
Any know a good place to get one from or should i play safe and go to main dealer??

 

the zerosports 71c thermostat is good.. if I remember correctly David Hendry is the uk importer for zerosports..

or the dealer for the standard 79c (iirc) thermostat.

Many thanks Simon.
