Turbo Chargers
Saw this today in the CCC Magazine
It’s a procedure that I have adopted over the years but maybe some may not be aware.
“It helps if you consider how a turbocharger works . Hot exhaust gases drive a small turbine, drawing in air and compressing it, this is often called forced induction. This means the turbo itself gets very hot, especially if you been driving hard, towing
or driving a heavily laden motorhome. The amount of heat held within the component can be quite considerable. As turbochargers are water cooled, if you allow the engine to idle for 30 seconds to a minute after you’ve stopped, it can let the water cooling system
draw heat away from the core of the turbo.
This means it won’t come to rest at a temperature so high that the lubricating oil within the shaft components is damaged. In the worst case, this could cause coking in this area, leading to oil starvation and premature failure of the part”
I would have thought most would be aware but maybe some may not. To renew a turbo could be in excess of a couple of grand.
