Yeah, I'm a little nervous about the water pump being really, really stuck to the timing chain cover with the FIPG/RTV gasket material.
I can over-think anything, and this might be really dumb, but does anyone think that a length of heavy fishing line tied to 2 handles (short wood dowels or something) would be able to slice through the gasket material without the risk of damaging the mating surfaces? (using a sawing motion like a pocket chainsaw)
I have removed a few water pump and some have FIPG, the fishing line idea could work if the pump was not installed with excess of FIPG, a smack with a wood board have worked really good in my case, but I wasn't planning on keeping the pump. I would suggest that you get hand on work, the only way of telling how stuck the pump really is, is getting it removed.
Is not a hard or difficult job at all, just keep in mind the precautions that are posted here and a FSM could be handy for the proper torque of the bolts.
Best of luck with the project and any questions use the forum!
