2 simple questions ...

Hi,

just wanted to check before I try anything.

First I want to change the intake, to do that I need to lower the coolant level, right? Is there a way to know how I much removed coolant is enough to remove the intake without creating a mess?

Second, I want to change the engine mount (72 style, square rubber mount) but I don't have an engine crane. Can I jack the engine by putting a piece of wood of 2x8 under the oil pan, and push on it with a floor jack? Is there any other trick?

Thanks
