I'm in the process of resurrecting a '95Z from the dead and just had the whole cooling system worked over. New, hoses, radiator, heater hose, low coolant sensor, master cylinder the whole works. After about a week or two now the low coolant light still comes on and stays on after firing it up and running her after the first 5-10 mins. Guages are fine. She maintains 185-190 all the time. And yes I check the coolant regularly like a mother checks on her newborn. So what's up? Is there another sensor I'm missing? A short in a wire? Thanks for the help comrades!

 

you may have an air bubble did you open the bleeder valves

 

Well I thought that too(bubble) but where are they? I'm no mechanic and never claimed to be. Just learn as i go. Also, is there a possibility that sensor gets "flipped on" so to speak when filling it up with coolant?

 

here you are

 

Check out this link. Lots of great info on 4th Gen cars and common problems / solutions.

Also, when bleeding air out of the cooling system, it helps to have the front of the car raised up. I have a steep driveway to use, but car ramps/jack stands will work just as well.

 

Stix80 and Gpa'swgn....I appreciate the help

 

well i think i might know the prob. took it back to the mech today and he said the heads may be cracked. Low coolant and no signs of leaks. we'll see!

 

are you seeing coolant in the oil? pull the plugs and see what they look like.

 

what in the blue moon are you talking about?

when you perform a visual check is the coolant low?

If not, then unplug that confounded sensor like a gazillion others of us have done because it doesn't work. It only lights on your dash and has no effect at all with the computer

 

yeah I've checked the coolant and it's low. But...even after having the cooling system worked over 2 weeks ago it's STILL leaking coolant somewhere! I don't know where. I'm not a mech. That's what my research has been telling me and the mech's opinion as well. I won't know anything til tomorrow though. This is purely speculation at this point. I don't think it's the water pump because there is no visible fluid on the ground. So tell me what you think.
