Engine Cooling problem
2000 Chrysler Sebring 6 cyl Two Wheel Drive Automatic 106, 00 miles
the car overheated and blew a freeze plug, the freeze plug was replaced, along with a new water pump and thermostat, the car can sit and idle and not get hot, drove it about 18 miles, and it did fine, the pulled back in the drive way and let it idle and the temp start to rise. The water blows or comes out of the raditor cap? Don't see any other leaks but it builds up pressure and starts coming out of the raditor cap and then the temp starts to go up
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
