highland-celica Posted April 14, 2015 Report Share Posted April 14, 2015 Noticed the other night that my temp gauge never went up to the normal half way after about a 20 mile drive although warm air was coming out the vents so stopped at a petrol station checked coolant level.. It was ok blead it for a while and set of again and done the same thing. Been sitting in the car running idle and it's picked up temp to half way and fans blowing hot but 5 mins into driving it's went back down ?? Any ideas and is it a big problem ?

Dickie Posted April 14, 2015 Report Share Posted April 14, 2015 (edited) Sounds like a stuck thermostat. If it's stuck open the engine will be cooled too much by the air when driving along but when sat in traffic or just idling at standstill it will pick up back to normal temp.

Klaxon Posted April 14, 2015 Report Share Posted April 14, 2015 (edited) +2 yeah thermostat that sounds like, you probably get about 19mpg tops with that down so best to sort asap, its a cheap part and cheap fix Edited April 14, 2015 by Klaxon Link to comment Share on other sites More sharing options...
