Of course we do, even in the Tropics, it protects, lubricates your system and runs cooler.

Problem solved, we had the Radiator at a Radiator service for cleaning and leak testing, they said its all OK, but no circulation and the rat gave me the idea that something must be clogged. So we replaced the Radiator today and the car is running fine. Thank you all for your kind help!

That sounds interesting, we have many cases rats eating wires, will check and flash. Today we unstall a new radiator.

The heater is not getting hot, strange, maybe the heater valves are not working, since the heather is never used here.

Thanks a lot that really helps!

Model year 2008, petrol V8, Vin SALME15478A288408, when we test the overheating we do not put a thermostat, the temp here is always 30-35 centigrade.

Thank you very much for your quick reply, but the thermostat is removed for that purpose. (it overheats with and without) It looks like no circulation, but what can stop the circulation? (water pump is new, radiator tested)

It seams there is no coolant circulation, one side of the radiator is real hot and the other cold. Now the radiator just came back from leak and pressure testing- the say its OK, waterpump, is new, thermostat is new, coolant reservoir new. There is no water in oil, and no oil in coolant., but...

Hi I am new, my name is Chris from Gerberauto with a small shop in the Philippines, I would like to learn and contribute if I can, in this forum. I am starting with a mysterious overheating problem on my 2008 Range Rover V8, which we cant fix over here.
