As part of my winter 'why not' maintenance an my 240z, I wanted to swap the water pump....no reason..other than, I'd bought one as a while back and do not know when the current one was fitted....(oh and there's the small matter of my 1500 mile Euro trip this spring )....
anyway having read a few 'threads' on this...its clear the longer bolts can be a challenge to remove (err snap = nightmare)....
and...all but one of the bolts came out easily..the final one was TIGHT ..very reluctant to turn....but slowly, slowly I manged to coax it out (with help from a lot of PlusGas) ...you can see the amount of corrosion on the bolt is ugly...but I've got new bolts on order ....anyone have any ideas on how I can clean up the bolt hole/threads ?.
its the hole on the side of the block which is open ended (behind the alternator)....I could use a tap/die (but worried that could snap off in there and its kind'a limited access)..is there a chemical what will 'dissolve' the crud in the bolt hole ?
any ideas welcome
cheers Graham
