I have a '94 Z28 with a factory LT1 350. I replaced the water pump and now my low coolant light comes on after about 20 minutes everytime. The light comes on even when the coolant is over-full. My car doesn't over-heat but I am loosing coolant. I know the LT1 uses a closed system and have tried bleeding the system but only antifreeze comes out, no air. Does anyone know what could cause this?

I am currently experiencing the same problem. I first noticed coolant leaking onto the belts because I couldn't steer while sitting idle. I change the water pump about 3 years ago and I can't believe it's going out again. I had to change a raditor hose last month and it worked fine, but now this mysterious leak. I just don't want to believe it's the water pump again. Pretty expensive.

I think my radiator is overflowing my reservoir. I replaced the thermostat when I replaced to pump. I'm wondering if it might be my low coolant sensor? Does it have anything to do with the way the coolant is circulated?

I read about this problem on the F-body forum a while back, if memory serves it's due to a bad sensor. I was going to do a search there for you and try to find the thread but the site is down right now.

Good luck,
