I put a post up earlier about overheating in traffic and slow speeds and temp seems to cool down on a run

Changed fan clutch and works fine
Changed water pump and timing
New thermostat

Done a sniff test and pressure test and seems fine at the coolant tank

Radiator has been checked, flow seems fine but it does not get hot

Head gasket?

Might be best to continue with your old post to keep a record of what was tried.

Same things I said last time really, compression test, leak-down test. Look for oil in water or water in oil (mayo anywhere) before you pull the head.

How sure are you it is bled correctly? As I say some cars can be a pig

Ye well we changed water pump and timing as it needed doing and will check tmoz for proper bleeding

I suspect a radiator problem as rad stays cold
While it’s all overheating

Sounds as though the thermostat is stuck shut.
