ExR32 10 Posted January 10, 2014 Hi all, Just today my temp light started to flash after driving for a couple minutes. The temp sensor works and it has water etc. Guessing its not from over heating as car was barely warm. Any ideas? Thanks Quote Share this post Link to post Share on other sites
Stonejag 10 Posted January 10, 2014 It's not a temperature light, it's a coolant level light activated by coolant bridging the two pins sticking down into the expansion tank. Check the level and top it up if low. If it's alright then the connector has probably gone bad. Stone Quote Share this post Link to post Share on other sites
ExR32 10 Posted January 10, 2014 Ah ok mate, thanks, will check the level tomorrow. Maybe I put too much coolant in it yesterday or not enough as I replaced the front flange yesterdsay and filled the level back up. Quote Share this post Link to post Share on other sites

Stonejag 10 Posted January 14, 2014 No worries, I've been caught out by that before ;) It's not 100% obvious. When you top it up after removing parts you can get quite large air bubbles into the system, you're supposed to bleed it all out by running the engine with the expansion tank cap removed until the reservoir boils over, then switch off, let it cool and add more coolant (to the max mark since it's hot). If you don't then the level drops dramatically when you first drive it and the light flashes :) Stone Quote Share this post Link to post Share on other sites
