Overheating issue

[Dantjaus]

Hey guys, need some good minds, here.

So I have an overheating issue. The temperature goes all the way to hot then will come down to normal then all the way back to hot every now and then it’s not the heads down the carbon test. Didn’t come back at all. Done the thermostat done the water pump, new coolant only thing I can think of is the fan clutch.

Did you use a good chemical flush to clean the cooling system before replacing parts and adding coolant? If it's the fan clutch, it will only overheat when not moving.

Yeah hey mate, I burped the system but the thing is when I’m either going really slow or stopped that’s when it starts to heat up. It’s now sort of fix the issue and when I move over 60 k’s an hour it actually works and actually cools down the system

Most likely fan clutch if only overheats at idle, low speed.
