If a 1995 Chevy Cavalier overheated and will not start, try checking some of the sensors near the radiator. The radiator could be leaking which caused the overheating, and in turn, caused a sensor to get wet in the engine compartment.
Dry off all of the plugs and wires. Dry off the distributor cap and try starting it.
Hopefully, it's the thermostat... but, if the engine has seriously overheated it could be a damaged head gasket caused by a warped head. Engine heads will warp slightly when the engine overheats, then there is insufficient pressure on the head gasket and the gasket will leak.
1970-71 Chevrolet Small Block 400cid heads.
The heat generated by the converter can back up into the engine and damage it. Cause it to overheat, blow a head gasket or damage the heads.
It doesn't necessarily mean a bad engine but with this mileage, you might as well go for a rebuild since if you just do the head it porbably will start using oil.
If the motor was NOT started, if the head bolts WERE NOT torqued, then you would just need to make sure the head gasket was not pressed and put the head on correctly (head gaskets are cheap replace it if there is even a question). If the head bolts were torqued (tightened at all) you must replace the head gasket. If the motor was started then it depends on how hot it got. Water passages normally do not line up so the engine overheats very quickly because there is no coolant flow, oil flow is also interrupted in most cases; this leads to a myriad of problems including cracked heads, scorched bearings, etc. In this situation it is best to remove both heads, check the block deck to ensure it is not warped, and have the heads tested (re-tested) to ensure they are not warped or cracked.
Needs a new head gasket, and maybe heads and pistons.
Remove the cylinder heads from your Chevy engine. Remove the head gasket and clean the head gasket surface. Put the new head gasket on and reverse the process.
You can blow a head gasket for one thing. You can also warp the heads. All sorts of bad things can happen when an engine runs hot. Your first priority is to find out why it overheated.
They are one and the same engine.
yeah, but it might blow a head gasket, i wouldn't chance it
Could be many things like a stuck thermostat, blown head gasket, warped heads, bad water pump etc.
Sandwiched between the heads and the engine block.
replace the intake gasket set
If the vehicle smokes either the gasket was installed improperly or then heads were not checked before being reinstalled and one of them was warped if the vehicle overheated when the head gasket blew then most likely its a warped head. Devan
That depends on how extensive the problem is, if it is just leaking externally it is cheaper to replace the gasket. If it has severely overheated, the heads can POSSIBLY be warped, but even so may be able to be repaired. If the coolant got into the oil and was not noticed for a considerable amount of time, internal engine parts can be severely damaged which would warrant engine replacement.
Cylinder heads are installed on a Chevy 454 big block engine by placing the gasket down on the engine block and positioning the heads over the marking tabs. The bolts are then installed and torqued to specs in sequence.
yes!!
