So, why didn't you just take tension off the serpentine belt a bit and rotate the pump pulley by hand to where you wanted, rather than crank the engine over and hope the pulley ended in the right spot? Probably could have drained the coolant from the pump during removal, but that might have been messy.

Mark,
What kind of torque wrench do you have to measure inch pounds? It has a nice click to it…mine doesn’t click that loud. Thx.

Brian says:

Mark,
I’m going to swing by next week and pick you up so we can do mine along with the valve cover gaskets. Did you use any gasket sealer on this? See you soon…..

Great Video. Takes me back to my 3800, and the trouble we had in trying to diagnose engine shudder on the highway. [tip: was the lower half of the tri-coil block, int connections causing incorrect info from crank sensor to ECM] Loads of fun doing similar parts removal. Glad you got it replaced without any broken parts
