Stuart – who as the owner of Graeme Cooper Automotive might well have known better, recently did not anticipate the failure of a cooling hose right under the supercharger when he removed and upgraded the charger. Guess what? You got it – the supercharger had to come off again to fix the leak.
I had a similar problem some time ago on a RR Classic when after removing most of the dashboard, I did not change the heater core or heater hoses at the same time.
The moral of these stories is to look around carefully whenever any major component is removed to see what else might need fixing at the same time!
