Yes - if thermostat does not open allowing coolant flow The simple answer is yes. They can either fail open (engine never heats up or heats up slowly and temp fluctuates) or, more normally, closed (engine overheats). But before you condemn it completely, make sure the engine is cold, remove and inspect the 'stat for obvious signs of damage then place it carefully into a pan of near boiling water. After a few seconds a gap should appear between the centre an the outside rim. New stats are relatively cheap but it is essential when replacing that a good seal of the cooling system is made. To stop vapourisation and to keep the temperature down cooling systems work under pressure. It is worth checking for minor leaks / weeps and the proper action of the radiator / expansion bottle / filler cap. You don't say which vehicle it is but they all use smilar principles.
It could be a head gasket or cracked head. With the engine cold, take the radiator cap off and crank the engine. If the head gasket is bad coolant should shoot out of the radiator. 12 inches to possibly hitting the hood.
A lack of water in your cooling system will cause your 2002 Pontiac Sunfire to overheat. A malfunctioning thermostat can also cause it to overheat.
Maybe because there's no such car? The last year for the Cherokee was 2001. I had the same problem on my 2003 jeep grand cherokee. One reason it will stay on is after you wash it or a good amount of water gets in the engine. If it is below freezing the water freezes in the radiator causing the fan to continuously run
flush your cooling system, you may have blockage in your radiator not allowing the water too cool, but if the radiator is that plugged up its probably no good. look at the radiator to see if there is any corosion or small leaks in the little fins in the middle, i have had a few that were plugged so bad that when i flushed the radiator it leaked. if that does not work it could be the water pump. ive also had a plugged heater core, and extreme amount of rust, from poor coolant system management, plugging off water ports in the engine and in the head gasket on the engine.
Radiator in need of cleaning or bad/stuck thermostat maybe. Check the fan clutch to make sure it is operative. The fan clutch doesn't engage until a certain temperature is reached; otherwise it is free-wheeling. It needs to engage in order to cool the radiator.
No low oil will not cause your car to overheat. But there is a couple other things that can cause your car to over heat, like a bad thermostate that's located in the block of the engine or can be the water pump not cycling the water into the engine. Hope this helps
It can be a significant contributing cause, especially if it's bad enough to keep the system from pressurizing.
If you allow the engine to overheat severally, yes.
yes
A bad water pump or thermostat can cause an engine to overheat. A plugged (clogged) radiator or heater core may also cause an engine to overheat.
The thermostate could be bad or a air pocket somewhere in the cooling system wont let the coolant circulate properly,
No completely separate from engine/cooling system
Yes it can. If there is a bad wire in your harness the ballast resistor will get hot, in which causes your coil to overheat and cut out or burn outline.
A bad freeze plug will leak coolant and cause the engine to overheat.
Not likely but possible.
yes. but there are several other things that can cause it to overheat. not enough coolant, bad belt, radiator blocked, bad thermostat,bad water pump to name a few.
Over heating and no heat from the heater.
