Got in the car (09 cr vrs) got a mile down the road, temperature was already at 90, which is way quicker than usual, pulled over checked radiator hoses and they were cold but cooling fan kicked in, checked heater and it blew red hot. Guess the thermostat is jammed shut. Glad I took out aa repair insurance.

Are you not able to continue your journey keeping a close eye on the temperature gauge?

Journey wasn't absolutely necessary, so done a U-turn and dumped it outside my house. AA man has been and confirmed my diagnosis, just need to get it booked in for repair now.

Fingers crossed it won't be too expensive.

Should only cost me the £35 excess on the repair insurance policy
