How does the cooling system on a Ford Mondeo work?
How does the cooling system on a Ford Mondeo work?
Your Mondeo’s cooling system works by cycling the engine coolant from the engine through the radiator. The water pump pushes the water through the entire system. The thermostat opens up once the engine reaches operating temperature and allows coolant in. If any part of this system fails, your Mondeo will eventually overheat.
Why is the radiator on my Mondeo overheating?
If your radiator overflow is full (and you radiator fan is kicking on), it is very likely that a bad thermostat or bad water pump are causing your Mondeo to overheat. Of these two, the thermostat fails more often than the water pump. It’s also much more affordable and easier to get to.
Why does my car have a radiator fan?
You probably already know the purpose of the radiator and the cooling system in your car. When you are driving fast, the wind is passing through the radiator to cool the coolant down without issues, but when you are driving slow, there is no wind pushed through the radiator. This is why we use a radiator fan.
Where is the relay on a radiator fan?
The fan relay is often located in the engine bay’s fuse box, but the best way is to check your repair manual to find where it is located. Testing a 4 pin relay is often very straightforward. Remove the relay and give 12 volts to pin 30 and 85. Ground pin 86 and check if there is voltage coming out from pin 87.

Is there a coolant leak in my Mondeo?
Detecting the leak is a process of elimination. Keep putting anti-freeze in, it is good for the engine, and helps identify leaks by smell and dried residue. Cardboard sheets in strategic locations are useful, I found a coolant tank leak that way. The water must be going somewhere, either leaking out as water, or as steam in the exhaust.
What causes a Ford Mondeo engine to overheat?
If your Mondeo’s engine gets hot enough, the coolant will begin to boil over and manifest itself as steam coming up from under the hood. It does this to relieve the pressure on the cooling system before lasting damage can be done to it. 3. Blown Head Gasket If your Mondeo is run for too long of a period while overheating, the head gasket may blow.
What’s the solution to the Ford Mondeo common problems?
Solution: A common problem has been identified with the above models and an insufficient signal from the camshaft postion sensor (CPS). The fault code P0340 may have been triggered which relates to the CPS. A revised wiring harness / sensor should be installed which increases the sensor signal from 5 volts to 12 volts.

Solution: A common problem is over heating and subsequent high resistance of the speaker multiplug terminals. The solution is to fit a revised speaker loom multiplug that have improved heat resistance. A revised speaker loom multiplug has been fitted since 06/1997.
Why is my Ford Mondeo Mk3 overheating?
Sounds to me like you may have a blockage in your heater matrix. this may cause overheating in a modern car, because where cars used to have a water valve to control heat, now most have full flow through the matrix at all times and the heat output is controlled by flaps which mix warmed and cold air.
Is there a problem with my Ford Mondeo?
– There are no strange noises comuign from anywhere in the engine bay. The next thing to replace is the radiator or the water pump. I don’t know which one to go for and both are about £170 fitted; and even then, theres no garuntee it will fix the problem.
Why is the radiator fan kicking in in my Mondeo?
– I have noticed in the past couple weeks or so, the radiator fan kicks in after I shut the car off – regardless if the temp gauge is in the red or half way. Simpyl assumed its because of the hot weather recently. – Have had an oil change as (I thought) the oil was a little low on the dip stick; garage said it was only a litre off full.
