i would be looking at the head gasket, if it wont start the engine could be hydro-locked meaning the cylinders could be filled with antifreeze. probably not any long term damage if this is the case.

Can your car function without a thermostat?
it can start but it won't go far as the engine will "explode" because of the increase of temperature. A thermostat regulates the temperature system of your car.. Usually the engine will run too cold with out a thermostat. That will hurt the efficiency of the engine.
How do you change the thermostat on a 1993 Pontiac Transport?
follow the top radiator hose to the engine. that is where your thermostat is. you will have to drain the radiator, remove the engine side of the hose and remove the thermostat housing to access it. remove thermostat clean mating surface of housing and engine, install thermostat, install housing, secure radiator hose, fill with coolant. start engine and check for leaks.
How do you stop your 1986 crx si from over heating?
It could be a Head Gasket, Thermostat, water pump, bad radiator or just needs coolant. start with the cheapest which is a thermostat.
Where is the thermostat located on a 95' 22L Sunfire?
Start at the radiator and follow the upper rad hose to the engine. The hose connects to the thermostat housing. The thermostat is located in this housing.
Why is my heater constantly running in my house?
Thermostat turned all the way up,thermostat defective, thermostat wired incorrectly, heating unit wired incorrectly, fan or heat relay stuck closed are the things I would look at to start.
What can a broken thermostat in a vehicle do?
In very short: If the thermostat stays open, the warm-up time for the engine will be significantly longer, resulting in unwanted start-up wear. If the thermostat stays closed, the engine coolant can not circulate through the engine and cooling system, resulting in the engine overheating, as the coolant is used to keep the engine in a specific operating temperature.
How can you bypass a thermostat on a 2000 Saturn LS?
You CAN just remove it; but that introduces another set of problems. The computer monitors the engine temperature, and if the engine is not warming sufficiently the computer will start to report a fault. A cold engine does not perform as well, and if the thermostat is removed the engine will not be able to reach operating temperature. The thermostat restricts coolant flow into the radiator while the engine is cool. Once the engine warms to operating temperature, the thermostat opens, allowing excessive heat to be dissipated through the radiator. Removing the thermostat is NOT recommended and can significantly affect performance and engine wear.
Engine runs cold in 2001 Z3 roadster Is there a fuse or switch for the thermostat so you could check if its bad BMW won't tell and want to have thermostat and housing replaced?
If your dashboard gauge is ok and the needle is moving when the engine start to warm up but never attempt the middle you have to check the thermostat as follow: you start the cold engine and carefully you keep your hand on the hose which transfer the cooling fluid from engine to radiator. If immediatelly after starting the engine the hot water goes through the hose, is 100% shure that thermostat is blocked open and needs to be replaced. A blocked thermostat in the position closed will cause more damaged because the engine will be overheated and the headgasket will be "burned".
Why does the engine temp go down after warming up?
When you start the engine, the thermostat is closed. After the coolant warms up the thermostat begins to open up allowing coolant to flow thru the raditor. When first started the temp will go a little past what the thermostat is set to open at. After the water begins to flow thru the radiator, the temp will fall to whatever the thermostat is set at. The thermostat holds the coolant in the engine until it warms up. As soon as the engine is warm, the thermostat opens allowing cold coolant outside the engine to mix with warm coolant. The temp drops, the thermostat closes again, until all the coolant is warm.
How do you replace the thermostat located on a 1994 Mazda Protege?
The thermostat is located in the cooling neck located at the end of the cylinder head next to the distributor. Instructions: Drain coolant, remove both bolts to thermostat housing (one bolt may not come completely out because of a sensor and expect much coolant to pour out), unstick the thermostat housing from the engine, remove thermostat from engine, clean all gasket surfaces, install thermostat in engine with the spring towards the inside of the engine, install gasket with thermostat housing, tighten bolts, fill coolant, start and check for leaks.
Why does a ford temp overheat when you first start it?
Most of the time it is because the thermostat has gone bad and is not opening at the proper temperature. Cure: replace thermostat. If the thermostat has been replaced, flush the radiator. Buildup of residue in the bottom of the radiato0r will cause overheating, but it is maintained over heating, not temporary.
Why would the radiator fan continue to run after the engine stops after the thermostat was replaced on a 2002 Nissan Altima?
Ingeneral, the fan will run only if the temperature of the radiator is above the normal range. If the fan is running, then the radiator must be over temp unless the radiator fan thermostat or it's relay is defective. If the radiator truly is over temp then you have a larger over-heating problem You state the thermostat was replaced. if you replaced the fan thermostat then either the radiator really is over temp and it is doing what it should, or there is a problem with the thermostat-fan relay or switch. If you replaced the engine thermostat that controls the flow of coolent between the engine and the radiator, then that probably wasn't your problem and you should look elsewhere for an overheating cause. I would start by determining if the engine actually is overheating or not. If it is, I would look for coolent system problems like the engine thermostat (if you didn't replace it already), water pump, leaks, scale build up in the radiator, or blockages in the system. If the engine isn't overheating then I would consentrate on the fan, fan thermostat and relays.
