low coolant light
if your low coolant light comes on from time to time and its not low at all but is exactly where it should be and the temp is decent then does that mean i have an air bubble somewhere? does that mean im setting off a different code somehow as well?

Re: low coolant light (1996man)
To my knowledge, the Low Coolant probe is stuck into the top of the radiator although I havent ever gotten in there and tried to find it, I had my Coolant warning come on a couple weeks ago, and burped the system again and it hasnt come on since.

However when you start it up, even cold, the level can drop to below the sensor. One of the reasons, IMHO, it will go off as the engine heats up is that the heated coolant expands.
Two suggestions: as someonelse said, burp it! I believe your model has a shrader valve in or around the thermo housing for this purpose; and check the radiator cap, if it is old, discard it for new. A worn seal can allow expanded coolant to go to the overflow and allow air, not coolant, to come back as the engine cools down!
Do them both, but I would lean to radiator cap, There's air in there now so "burp it" anyway

Re: low coolant light (1996man)
I had this same problem a couple of weeks ago when I flushed the cooling system on my 89.
The low coolant sensor is on the right side of the radiator just below the radiator cap. Check to see if the wire has come off the sensor or if the connector requires cleaning.
I'm confident the cooling system will dispell air into the overflow tank after a good run, and there should be no need to bleed anything.
Good luck. :thumbs:

Re: low coolant light (lrc89)
My 86does the same thing every time the coolant system is drained. I read a thread on this problem that suggested reving the engine so that the coolant is sucked down by the water pump and add coolant while the revs are up then replace the cap before returning to idle speed. That worked the best for me. But, eventually the system will bleed out the air anyway over time and repeated heating and cooling. One other thing that helps is to drill 4 1/16 inch holes around the flange of the Tstat which will help in bleeding out the air and won't affect the tstat function.
