I have been cleaning out the black crap from inside my engine.
I have done the throttle body, Intercooler and connecting pipe work.

I want to do the intake manifold but not sure how to take it off.
My workshop manual states that the coolant must be drained from the car.
Is this true?
Plus it has no photos to help.

I have searched and all I've really found is how to clean it once of and to replace the gasket when re installing.

Regards

Shaun
