hey guys i have a problem that i cant figure out. i flushed my coolent in my 91 but the light on my dash is on i checked my owners manual and it showed that the coolent was low i checked everything and it checked out fine does this mean that my water pump is going out or the sensor next to the rad cap is shorted? i followed the directions on how to flush from lexls.com

Did you try to bleed the air out?

If the light is on make sure that the overflow tank is full, and do it while the light is on. E.g., exit the car and pop the hood while the light is on and the engine is running and verify at that time that the overflow tank is full. If the tank is full and the light is still on then the sensor is either dirty or defective, and will need to be cleaned or replaced.

I had the same problem just replace the sensor the top of the over flo tank and it cost around 120.00 from the dealer.
