Well its been running a little warm on hills for a while especially in slow convoys but it was also taking longer for it to cool back down at the top with the gauge reaching above half way a couple of times. So its time to wash the radiator. Never a pleasant job esspecialy when you have to keep the engine bay at its current concourse condition.
Snapped 3 of the 4 bolts getting the radiator out but luckily a set of mole grips was able to wind them out the back. then had a look at the front of the radiator. It was slightly dirty
the back wasnt as bad
Half hour with hose sill didnt get through so soaked it for a couple of hours then all was good
Put it all back together and it runs much cooler. Only lost blood from a dozen places during the job as well
