Another tip, if you are removing the intake manifold, drain the cooling system, then remove the temp sending unit. Then use compressed air to blow the manifold empty through the radiator. make sure you leave the drain plug out of the radiator so it will drain. If not you will pressurize the system and be cleaning anti freeze off the ceiling.
When you pull the intake off, no
antifreeze will get into the crankcase.
tip 4 - buy apple stock
