Well after replacing the Viscosity Oil in the Fan Clutch, replacing the Thermostat, having the Radiator serviced and new tanks fitted . . . . I still had heating issues.

My Issue ended up being the Water Pump.

Late October 2020, I pulled the water pump off, upon getting the Fan Off the water pump had No visual leaks from the weep hole, the pump once fully removed look serviceable! No visible damage!

After fitting new New Water Pump I've had no further Over Heating Issues since.

ReggieRay I hope you've had some joy with your vehicle Mate.
