I have recently been getting a low coolant light and there is some fluid on the edge of the battery closest to the radiator cap. All the lines and connections there look dry and there is some slight fluid at the edge of the radiator cap. This has happend since I had the lower radiator hose pop off and lost ALL my fluid. I refilled the fluid and bled it using the top bleeder only. Could there be air int eh system? do I need to rebleed it using both bleeders? or is it possible the cap itself is not sealing? This is driving me nuts, any help would be great.

 

Get a new cap and if you have enough coolant in the radiator, just unplug the switch. They go out all the time and aint worth replacing. Everyone here just unplugs it. As long as you know that you have fluid and your not overheating, you dont even need the sensor.

 

You need to bleed BOTH bleeders. It is absolutely necessary or I garuntee you will have air in the lines especially since you blew the hose while the car was running and lost all the coolant.

 

Great, thanks guys. Will get a new cap and bleed BOTH bleeders tomorrow. Merry Christmas.
