1. The pump allen mounting bolts are frozen in place. I purchased a metric allen 3/8" socket but it only served to round out the allen hex inside the bolt. So, how about I use my Makita to cut the water pump off the engine in pieces to get at the bolts? (I no longer care about losing the $60 core charge)

2. An electric cable threads through the water pump to a sensor at top of flywheel damper degree wheel. What is it and what precautions to remove it. Is position critical?

3. I had my thermostatically controlled fan clutch replaced by the dealer ($400) last year but now can't get it off. I have the big allen tool but can't figure out how to hold the belt/wheel to keep it from turning when I try to loosen the bolt. I now have the radiator out so have a bit of room (don't know how anyone would do this job with radiator in place). Do I read the manual right that there is a hole somewhere in the wheel which can be used to pin the wheel in position so the bolt can be removed?

4. I do have radiator out being core/cleaned/re-rodded at the radiator rodding shop. The serpentine tensioning assembly is removed and the power-steering pump is laid back. Dealer wanted $800 to replace the water pump and now that I've got parts all over the garage and I'm working in the rain...wish I hadn't started this thing. I desparately need hand-holding.

Tell me nice things please, being 70 wasn't supposed to be like this. Criticize my need for a haircut or my spelling and I'll ...
