Hello,
My moms 1996 Grand voyager 3.6 V6 (over 200,000 miles) has been having some problems with overheating. It all started when the radiator blew out the plastic part over 6 months ago. We towed it home and put a new radiator on, the A/C some how got messed up during the installation and hasn't worked since, but thats probably unrealated. It worked great after that untill a couple months ago, When the engine overheated in the parking lot, Somehow most of the water had leaked out, my mom was able to fill it with water and drive it home. We replaced the thermostat and put a new lid on the radiator, but it still loses water...very slowly... the way we've been driving the last 2 months is by refilling the plastic antifreeze reivoir with water every 40 miles, as long as the resivoir is kept filled the system won't lose water but when the resivoir goes empty the system loses water. It only loses water when the engine is on. after a drive the engine smells really hot but the heat gauge in the instrument cluster never goes past the middle(it could be broken). We've looked countless times for leaks both hot and cold and never seen a drip.
I'd aprecaite any help I can get.
Thanks in advance

If you are absolutely sure there are no visible leaks, the only other place the coolant can leak to is in the engine cyclinders and out the tailpipe. That means you either have a cracked block, blown head gasket, or a warped or cracked head. Indications of any of these, besides your vanishing coolant, are a white vapor/mist out the tailpipe, oil droplets or shean in the coolant, or milky/frothy looking engine oil. You may notice a loss of power.
Recommend you check for oil in the coolant reservoir and radiator and drain the oil and inspect. A compresion check would be my next move.
There is an outside chance the coolant is leaking externally somewhere then hitting the exhaust and vaporising. You'll have to give it a close inspection to catch it.

Hey,
Thanks for the reply, I've checked all of these and everything is looking ok. It still may have a minor leak in the cylinder. My dad said that someone he talked to had this problem and was able to solve it with some type of glass based sealent. So i'll have to look into this and see.
