Earlier in the thread there was mention of water pump replacement. How involved is this? I recall reading on the g37 site (I think) that it involves a lot of R&R, something about the front timing cover having to come off to gain access to it??
Edit: I just looked at the fsm. It's a cluster f*ck to get at it. The above is correct about the front timing cover removal.
tl;dl $$$$$$ to replace water pump.
