Fan clutch is fine
even at Hwy speeds this is happening

I will be going and getting a new water pump today and will be installing it this afternoon

My ir gun is not reading properly it's all over the place
I can tell you both heater core hoses are hot and bottom of rad pipe is cold until you rev engine then it starts to flow

I've tried 3 diff Tstats all with same result
there is no air

I got nothing left to do at this point but to take out water pump and inspect it

Maybe the impeller on the water pump is corroted as I'm got the truck they still had the oem coloured coolant

Ok replaced water pump old pump looked fine but got replaced put all back with Atlantic British Tstat
truck is running 197 driving 204 idle it's 14 degrees Celsius here

I'm going to reinstall my black britpart tomorrow and see what happens

if it goes back to 215 then it's a bad lucky 8 stat
if it is a bad Tstat that would mean I got a bad Tstat from Atlantic British and one from lucky 8 that would be bad luck
