Yes
The most common cause of engine lockup is a lack of oil. Also, an engine overheating from lack of coolant can cause an engine to lock up.
No, only the compressor will lock up.
Supply of fuel (Gasoline or CNG) should be stopped. Try to start the vehical with no fuel supply. It will comsumed the pressure build up due to Vapor Lock & engine will start. Then after engine star , you can open the fuel supply.
Overheating an engine can cause the engine to see up resulting in a complete engine failure. Overheating the engine can cause the head gasket to fail.
When the engine can no longer rotate.
It could, any engine can "lock up" if not maintained properly.
Failed thermostat.
An engine can lock up on a number of reasons but mainly due to mechanical failure for example if the Timing belt snaps... etc...
If an engine overheats the metal parts expand and the engine will seize up. A seized engine is usually unrepairable.
if the temperature goes up on ur gauge but it is not overheating means ur thermostat is no good
Uh, yeah. If it skips when a valve is open the piston can hit it, and it'll either break the valve or not, but if it doesn't, and it hasn't hit TDC it'll lock up.
