Today the radiator has been flushed out, I have swapped out the leaking heater matrix for a new unit and the blowers all work lovely now and good heat.
The temperature sender has been changed and the temperature Guage now works - however the temperature needle is sitting towards the high end of hot and not in the middle. It's not getting into the red zone it's just before the first white dot on the right.
Should this concern me? Thanks
