Low coolant light on and off

:lol2: My low coolant light came on and had to replace water pump, everything seems to be fine but low coolant light keeps coming on and off. My venture is 1998 with 116000 miles and need to know how to reset the low coolant light in the computer. I disconnected the negative cable and removed ecm fuse but no luck. Any advise on how to reset the ecm? Thanx.

Did you recheck the coolant level to make sure it is at the correct level? You may have a faulty coolant level sensor.

The coolant level has been fine for months (I replaced the water pump 6 months ago) but the light always kept coming on and off. That's why I thought I needed to reset the computer. Thanx very much for your help.

are you checking the coolant isn the resivour or in the radiator, that sensor is in the resevoiur.

Both are fine, radiatior and reservoir. I also flushed the radiator to make sure everything is OK but there is enough coolant in the reservoir. How do you change the sensor, is it located in the reservoir?
Thanx once again..... :)

Just want to tell everybody that I had the problem with the light coming on and off for 6 months but after flushing myself the system with Zerex radiator cleaner the light went of for good so I'm very happy now. I dont have the problem with the light anymore as well as the problem with the power door lock.
As always thank you all......

If i were you i would check your in take gasket, they are having problems , and they no about this
