A faulty thermostat in a 2001 BMW 325CI can cause a coolant leak. The coolant may be leaking out a crack in the thermostat or through a warped edge. In some cases the problem may be just a bad gasket and not actually a problem with the thermostat at all.
Yes it can. A faulty thermostat can cause overheating which will cause coolant to be pushed out of the system.
The coolant sensor moniters the coolant temperature. A faulty thermostat could cause the engine to run cool.
First you have to determine the cause. Could be a faulty thermostat, frozen coolant (insufficient mixture of antifreeze), low on coolant or possibly a bad head gasket.
Engine Coolant Temperature Circuit Range/Performance issue... This DTC is usually cause by a faulty coolant senor, but can also mean that your engine's thermostat is malfunctioning.
A lack of coolant, a faulty water pump, a stuck thermostat, or air trapped in the system can cause no circulation in the radiator. It is important to diagnose and fix the issue promptly to prevent engine overheating.
Many things such as low coolant, broken belt, busted hose, no oil, bad radiator, fan not working or a faulty thermostat.
Either a faulty thermostat or you have a low coolant level.
A faulty thermostat or possibly missing thermostat. The thermostat controls the amount of coolant flowing from the water pump through the engine and then to the radiator. If it sticks open it will not let the engine heat up to design temperatures.
Bad thermostat, plugged or damaged radiator, loss of coolant, ignition timing is off, faulty water pump, head gasket... and who knows what other problems can cause overheating.
In order of probablility: low coolant level, faulty thermostat, plugged radiator, damaged water pump, collapsing radiator hose.
Could be, low on coolant, stuck open thermostat, plugged heater core, faulty temp blend door actuator,
The most common cause of overheating is a thermostat stuck in the closed position. Other causes of overheating could be a clogged radiator, faulty water pump, a faulty radiator fan relay, a faulty radiator fan motor, no coolant or low coolant level.
