I took both bolts out just to get it past the crossover, and you first have to take off the thottle body and the breather tube....it also took me 4 hours the first time
The coolant temp sensor is located on the manifold, just to the left of the thermostat housing on the right side of the engine compartment. They are both located just under the air intake tube that attaches to the throttle body, and it has a small 2 wire connector attached to it. You can follow the upper radiator hose from the radiator to the thermostat housing to locate them. Good luck.
