Jaguar x300 Heater Core Flush Attempt

Last winter I had no heat from the heater in my 1995 Jaguar XJR at all. I read on a forum about using radiator flush to back flush the heater core, and some posts included photos and instructions which was great. Having nothing to lose I thought I would give it a go and record my progress. This video is a bit rough and ready, but will hopefully point you in the right direction if you want to give this a go yourself. My Jaguar definitely doesn't blast out hot air, but at least the air gently coming out is now hot.

It’s the coolant electric heater pump commutator brushes worn out ! A new heater pump will fix this problem

Some have successfully replaced just the worn brushes.
