Just bought my wife a 03 rendezvous, our first GM vehicle ever and our first american vehicle in many years. After about a month or 2 of normal driving it starts overheating, and i've come to the conclusion that it is either the lower intake manifold or head gasket, and just to leave no stone unturned I'm going to go ahead and replace everything. I've gotten almost everything i need to off of the front of the motor, but am at a loss as to how in the world i'm going to get to the back of the motor. if anyone has any suggestions, tips, or advice, i'd love to hear them.
