Contour Enthusiasts Group Archives Forums General Troubleshooting coolant level light stays on constantly

My coolant level light never goes out. I've replaced the sensor in the overflow bottle. I've cleaned out the bottle. I've tried disconnecting the sensor at the bottle and reconnecting and still light stays on. I've filled the bottle until overflowing.... I've checked all fuses. I have a new wiring harness from a year ago so wiring should not be the problem.........Any ideas.....

Thanks,
BT

unplug the light bulb

Try adding straight Antifreeze to the bottle.
The sensor not only measures the level, but the specific gravity as well.
If the mixture is too thin (too much water) or too rich (too much AF), the light will come on also.
It should be filled to about 1/2" over the MAX mark.

Easier than that is to short across the coolant level sensor with a piece of wire or the jumper plug you remove in older Ford vehicles to set the base timing.
