if you are losing your antifreeze its probably a head gasket or the heads are warped if not its probably the heater core
why does my 2002 chevy cavalier over heat after i change the thermostat and the water pump
thermostat
Low coolant? Bad thermostat? Heater core airbound, plugged or restricted? Water pump not circulating coolant?
I have 95 cavbalier new heater cor new thermostat puts out very little heat any suggestions
In a hot water heater, a thermostat regulates the heat
check that the thermostat was not put in upside down. also check radiator cap pressure
if it has a plastic impeller inside water pump it may be broke or faulty thermostat .check by boiling in water till temp its suppose to open
coolant levels or the thermostat
I'd check the coolant level first, then the thermostat.
im having the same problem with my 1994 I've replaced the heater core,thermostat,radiator,i checked the coolant, and it's not over heating or nothing and still no heat lol
bad thermostat or bad heat gasket
need to know what type of vec. 1992 Mercedes s500 sel
