   Just fitted a new radiator and replaced the coolant but I'm getting the 

warning light. Not sure why as the level is correct, any ideas?

	Have all the leads to the radiator been re-connected? You might also want to unscrew the cap from the expansion tank and give it a thorough wipe before replacing it.

	Did you try checking the wiring at the top of the expansion tank, and that the float moves freely? Also I had a warning light come on and it was due to the screw-cap not seating correctly. Couldn't work out why that was a problem, but it was.

	Float does moves freely but I'll try that again. I thought it would be a good idea to remove the expansion tank and give it a good clean which is probably why I've now got a problem. I didn't flush the entire system, topped up with a 50/50 split of water and coolant (5 litres). I assumed this would be ok? Replaced the hoses also.

	it may be the sender unit. Get a new one from BM's they're only cheap (less than �20 I think). Edited by dog man

	I tried another sensor at the weekend and that didn't work so maybe it's the sender unit like you say. Worked fine until the new rad went on. I did decide to give the tank and sensor a good clean while I was at it. sh*t!

	I had a problem where the float on the sender didn't float, ie even though the level was fine the float just sank. ??

	This is still driving me crazy. Shouldn't the fault light go out when the sensor connection is disconnected? I also put a test lamp to the connector and earthed it but it didn't light up. Help. Trying to avoid an expensive auto electrician.

	Finally sorted. When I decided to give the tank a clean (5 weeks ago) I put the yellow plastic sleeve (the float) on the wrong way round which caused the light to come on. Idiot!
