Your thermostat may be staying closed, if the top coolant hose becomes hot after the engine running for a while, then thermostat is opening ok. Next check to see if the bottom hose going to the rad is getting warm. If its staying cold then you may have a problem with the water pump not circulating the water around the cooling system. If thats ok check the rad cap is sealing ok. when the engine gets up to normal engine temperture remove the reservoir top filling cap which has a rubber pipe going to the thermostat housing. with the engine running there should be no water coming down the pipe and exiting the filler cap. If there is it could be the rad cap not holding pressure which it would need to be replaced or the head gasket is leaking and pressurising the coolant system.. hope this helps you..

SOURCE: The timing belt on my
4 or 6 cylinder? you say "heads" so I assume its a V6? A interference engine does NOT require a new engine. unless upon disassembly there is severe piston damage. A 2003 Galant isn't going to be worth putting in a $ 2500-3000 new engine. A car that has had scheduled service usually doesn't break the belt, its replaced long before that happens. Yes, you can take the heads off and get it serviced, new valves etc. On a V6 you also want to replace the water pump.

I think you need to replace cylinders head gasket ( O rings ) that sits between the sits betrween cylinders and engines block, to seal cylinder head of any leakge of oil or cooling liquids.
