My engine of my 89 chevy celebrity over-heated the other night. We found a leak in the lower radiator hose and replaced it. Only to discover that it was spraying water from a busted gasket near the hose near where teh hose connects to motor, but wasnt leaking from the hose. Not sure if the gasket was to the water pump or not since I know very little about cars. We replaced that gasket and had no leaks. We also went ahead and replaced the thermostat since we found no leaks we thought myabe the thermostat had gotten stuck. We refilled coolant and it ran fine with exception that it gurgled water back into the overflow tank alot not sure if that is normal or not, we also checked to see if there was water in the oil and there was none. The next morning I checked the coolant levels and the overflow tank was completely empty when car was cold. Also the radiator only was only about 1/3 of the way full. There dont appear to be any leaks anywhere when it is running or when it is not running. So im not sure what is causing it to burn so much water/coolant. Its been this way for the past 2 mornings that ive checked it. There is no discharge of water from the exhaust and no apparent missing in the engine. Can you please tell me if this is normal or what could be causing this and if it isnt normal what needs to be checked in order to fix it?

You may have has a large air lock in the engine, run the engine with the heater on until it reaches temp, leave the cap off, add coolant and let sit engine off until it cools down, level will drop as coolant contract, top up to safe level and that should be ok, keep an eye on the level and if it continues to drop re post for further advice.

Thanks for the quick responses. My temp gauge doesnt work properly. When it overheated the needle on the gauge got stuck and has not budged. So how long do I need to leave the engine running to get it up to temp? I let it run with the cap off correct? Then once it gets to temp add coolant? Then let it cool down still with cap off? Then top it off? I know I have alot of questions but I just want to make sure I am doing everything right so that way I dont cause further damage. Thank you for your help

The top hose will be hot to touch as will the coolant in the radiator, you may see air bubbles forming on the top of the coolant, at this stage that should be fine, it is just air bleeding out, leave cap off while it cools down, you may not have to add a lot of coolant, but let it cool just to find the correct cool level, remember coolant will expand when it get hot.
