If the thermostat in a vehicle sticks open the engine will not reach proper operating temperature. The open thermostat will prevent the car's heater from giving much or any heat during cold winter driving and will also cause the engine to use more fuel than normal.
If it's stuck open, no heat. If it's stuck closed, over heat.
yes it can lock open usually happens to people that have been drinking during a yawn but rare
It Depends On What Kind Of Thermastat You have
Thermastat
Sounds like your thermostat is stuck open. Replace that and see what happens.
If the engine were to backfire for whatever reason and the pcv valve is stuck open, the backfire could carry into the crank case and ignite the crank case fumes. I have seen valve covers blown off an engine from this situation.
stuck thermastat Also radiator fins being bent over from presure washing and or impacts (ie: Birds, rocks, road hazards, dirt) and clogging condensor and then radiator.
Stuck closed, you cannot. Stuck open, you are foolish
My brinks locked in the open position. What do I need to do to get it fixed
Overheating if stuck closed, no engine heat if stuck open.
Burn it
Stuck how? Lock? Door?
