Hi Jim,

Common overheating issue is a clogged/blocked radiator, cooling fans not working or a defective water pump.

Can you see that the rasdiator fans working when the engine reached the operating temp?

Yes, i am familiar with gas/diesel engines 1.6-5.0 liter engine.

to check if the water pump is defective, remove the radiator cap the turn on the engine. Make sure that engine  is cold when you do this. Notice the water inside the radiator if they are running. The water inside the radiator should be running or flowing, meaning the water pump is good. If the water is stan still then its a defective water pump.

before you replace it check it first by following the procedure that i mentioned. for codes P01285 and P01299  its pointing to the Cylinder head temperature sensor that is shorted or defective. that one needs to be replacced.for error P0480  its pointing for a defective fan relay and that needs to replaced also.

The engine will die as a fail safe mode when it reached to a certain temperature limit. your engine might not died because the temp sensors are not working,

for as long you are not getting milkshake thing in the engine oil then that means the engubne gaskets are still good. but you really need to address the fault codes and have the parts replaced immediately.

Start first by inspecting the water flow inside the radiator. That will tells you immediately if the water pump is defective. Next is the fan relay and the temp sensor. Replace it and observe the issue again. 

If the head gaskets are blown then you will see a milkshake thing on the oil. That means that the oil and the coolant are alraed mixed up. If the engine oil are still good then you dont have to worry about the gaskets. 

Since your friend has engine analyzer you can ask him to reset the fault codes. If the code went back after resetting then it means that the parts mentioned are defective and needs to br replaced. 

Hmmmm... the only thing that you will have exhaust gas in the coolant if the head gasket is blown and you will notice also that the oil is turning into a milkshake. Ask you mechanic to run a combustion leak test to verify that issue again. For as long as the engine oil is good then ou dont have to worry about the gasket. 

The problem is just a basic cooling system. But of course you need to be particular with the parts that you are going to replace. Like what I have mentioned, start first by inspecting the flow of the water inside the radiator then replace the parts showing in the fault codes then observe the issue. I have a feeling that the issue is the cooling fan relay only because the fan might not be working as it should to cool down the engine. 

Yeah because the analyzer tool will tells you also if the water pump is the problem. The codes that it was throwing is basic and can e replaced in less that an hour. 

Good luck Jim. 

Do you have further questions?

That might be a reader only and cannot perform a reset. Theres this analyzer in autozone that they use that can reset/clear the codes. 

I hope I was able to shed a light on your issue. 

Do you have furher questions Jim?

Dear Jim, It was a pleasure helping you with your Ford issue today. Here is a summary of the resolution.
Issue identified : vehicle is overheating
Solution Implemented : chat with cx and told him to observe the water flow inside the radiator for possible water pump issue. told him also to check the fan relays since the vehicle is giving fault codes about the fan rela and temperature sensor. Told cx to tr to have the fault codes reset first and see if it will clear out the error and if errors came back then he really needs to replace the parts. cx has no further questions. answer accepted.
