Top tank and hose is 87deg
Bottom was approx 64deg
Warm day 24 deg after a hours run(country and town running.
Will still do the water pump and radiator clean out just to double check but I’m a lot happier with changing the thermostat to an 80 deg one,not sure what the other was as no marks on it to tell.
Thanks for the help and information guys.
