Thanks for the ideas, I’ve had the viscous fan replaced this week and still getting overheating when driven hard'ish

My wife has been driving it on the school run and shopping with temp running normal.

The garage noticed the radiator is only getting very hot at the top +sides, but the centre is cool to the touch. The suggestion is either the water pump (which is brand new) or a blocked radiator..

If anyone knows, are blocked rads common and what blocking them, can they be unblocked or just replace it?

If it’s blocked and the pump worked would the pressure go up if tested with?

Thanks for your help,

Ben
