Since buying the car the heating has not really worked very well, well no scrap that, the heating has not worked at all until the car gets up to over 2000rpm. Which is never around town!
It has already had a new thermostat fitted and a flush through of the coolant system and heater matrix, all to no avail. The last thing to try is fitting a new water pump. We all believe that the fins on the old pump have started to break up and not pump so well. Mini's are well known for getting air locks in the system due to the layout of the pipework and the radiators. So the theory is that below 2000rpm the current pump just can't shift the air. It would also stand to reason why the radiator fan runs for so long on even a short drive. The pump is struggling to keep the coolant moving.
Whilst it is having a new water pump it may as well have a new auxillary belt, there is a belt tensioner that is grumbling and will be replaced and it may as well have an oil and filter change as well. We know where we are with it then. Although it does mean that next year both cars will be due servicing at the same time!
Progress, Hmmm...I never had that problem with my Mini in the -60's........but then a heater was classed as an 'extra'.
ReplyDeleteI seem to remember the heater in our Mini Park Lane never worked very well!
ReplyDeleteMind you it took the chill off better then this one currently does.
