Title: Coolant warning light is on?
Post by: VR6_Wherry on 22 January 2011, 15:58

I've just flushed my coolant system, replaced the bottle filled back up ran it for about half hour squeezing the hoses. Now the warning light is on randomly!

Any ideas guys? :(

What's your water temp guage doing..and did you get the right amount of coolant back in.. it's probably an air lock if there are no other signs showing..

As above, airlocks are quite common on these after a coolant flush. Id take the expansion tank cap off and let it run up to temperature again whilst squeezing the lower radiator pipe whilst keeping an eye on the coolant level; and top up as necessary. If you can try leaving the car over night without the cap on as well as you sometimes find theta the airlocked bubble makes it's own way up and out of the system over a period of time.

I checked it all over, everything was as it should be. Ran the car for about an hour as i was happy there wasn't a major fault! (Water pump was pumping, Temp gauge was sat at 90c and air locks were being massaged out the system..

Switched the car off, got a 14" pizza, switched the car back on "Hey Presto it's gone"

Very strange error, but thanks for all your help guys!  :smiley:

It's not that strange really.. refilling with coolant takes a bit of careful time to do it properly..most people tend to rush it and then end up with air in the system..
Glad your sorted anyways  :cool:
