My car overheated some time ago. The waterpump seems fine (no leaks or noises) so I replaced the thermostat. Same problem continued. I flushed the cooling system and put another thermostat in but that did not correct the problem. Right now the motor will get up to normal temperature on the gauge but no heat comee out of the heater. At the same time, the overflow resevoir is spewing out coolant. My NAPA guy said it could be a head gasket. Any ideas.

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: ,Pressure test the Rad. cap,Clogged radiator,air lock in the cooling system ,Fan clutch,Radiator electrical fan,collaspe hoses,water pump.
