In addition to what the wiz has said it can also be cause by a faulty water pump (usually mounted on the front of the engine & can be easiliy found by looking for the pullies & belts driven by the engine). Water pump faults can include a faulty or loose pully for the pump ie broken belt, or too much "play" in the belt pully assembly, a leaking water pump, blown gaskets/seals. In short anything stopping or restricting the flow of coolant from your radiator to the engine block is going to cause over heating so also be aware of dodgy radiators & blocked or damaged lines ect. You should be able to easily trace the hoses going from your radiator, engine & pump as this is the path water takes to cool the engine.

Enjoy & good luck!

Radiator overheating, no leaks anywhere, may be thermostat or water pump?
If your vehicle's radiator is overheating and there are no visible leaks, it is possible that the problem could be caused by a faulty thermostat or water pump. These components are responsible for regulating the flow of coolant and water through the radiator and engine, and if they are not functioning properly, it can cause the engine to overheat.
To determine if the thermostat or water pump is causing the overheating issue, you will need to perform some diagnostic tests and checks. Here are a few steps you can follow:
  1. Check the thermostat: The thermostat is located in the engine and controls the flow of coolant through the radiator. If the thermostat is stuck in the closed position, it can prevent the coolant from flowing and cause the engine to overheat. You can test the thermostat by removing it from the engine and checking it for proper operation.
  2. Check the water pump: The water pump is responsible for circulating the coolant and water through the radiator and engine. If the pump is not functioning properly, it can cause the engine to overheat. You can test the water pump by removing the drive belt and attempting to turn the pump by hand. If the pump is seized or not turning smoothly, it may need to be replaced.
  3. Check the coolant level: Make sure that the coolant level in the radiator is at the proper level. If the coolant level is low, it can cause the engine to overheat.
If you are unable to determine the cause of the overheating issue, it is recommended to have the vehicle inspected by a mechanic who can perform a more thorough diagnostic test and identify the root cause of the problem. They will be able to recommend the appropriate repairs to fix the issue and prevent further overheating.

2003 ce lancer car keeps overheating... thermo fan isnt working... coolant is going but no leak.. checked fuses all seem fine.. not sure what to do next
It should be either the thermostat or the water pump.The water pump will sometimes allow you to go about 25-30 miles before it overheats.The thermostat would likely be the cause if once the temperature guage starts going up,it kind of just keeps going and overheats.You need to avoid driving and overheating as much as possible due to very bad engine damage.Hopefully you have a second car.You can call a couple shops,they normally will give you a free opinion,just describe it with as much information as you can to get an accurate one.Also you can get free estimates unless you plan to self-repair.Good luck!

I have a mitsubishi lancer cedia model 2000 frequent stall when driving i switch it off and on again in the ignition and come to live again for a few miles and does the same again what could be the cause
If you have the GDI model,they were designed to run on very lean air/fuel ratio.
Once the mileage is up a bit a lot of problems can be traced back to a high carbon build up in the intake manifold.

My car's over heating and losing water. 2004 Suzuki Verona. Is this the thermostat?
Yes, it could be the thermostat, but overheating may also be caused by many other things. Ensure engine tune or other mechanical disfunction is not contributing to the overheat problem.
Replace the thermostat, but if overheating persists I suggest you carry out the following checks:-
1) Check coolant system is not leaking fluid due cracked/perished hose or hose fitting, leaking water pump etc,
2) Check engine cooling fan/s are operating as required when engine temp rises above cut-in threshold - check fan control relay is ok,
3) Check for collapsing radiator hose on suction side of water-pump when motor revs raised above idle.
4) Check coolant reservoir pressure cap is serviceable,
5) Check coolant system is properly filled - carry out any bleed off procedure specified to clear any air locks- (ensure heater core coolant flow is turned on).
6) Check condition of radiator core:-
i) for blockage of air flow to (bugs/grass etc),
ii) for core internal blockage to coolant flow,

Engine overheated
Hello, There are many things that can cause this problem. It could be anything from a blown head gasket to a water pump. If you want to eliminate the water pump, take the thermostat back out and leave out, start motor, and see if you have a good coolant flow from water pump. Also, ck your fan clutch. This won't necessarily cause it to overheat at road speed but at slow speed or idle it could. There is also the possibility that your radiator is stopped up. There is something else, although rare, I have seen happen. Check the small coolant return hose at the radiator to make sure something hasn't blocked the small plastic nipple. If this is blocked, coolant will not circulate.
Check your engine oil for any kinds of water contamination, check your plugs for water, if you have access to a coolant pressure tester, pressurize cooling system, remove spark plugs, let stand for at least an hour, then turn engine over and see if any coolant comes out. This may give you an indication that your head gasket is blown.
I hope this helps.
