Just to clarify what ive read on this site and in my haynes manual, to remove the heater core, ihave to remove teh whole heater assembly, and to remove the heater assembly i have to dissconect the two cables and then its a matter of 4 bolts from the engine side of the firweall and one bolt on the cab side, and then teh whole thing shoudl come out in one piece? while its out i am going to replace the wiper arm assembly as mine has alot of slop and play in it, from what i gather, its easy access to the wiper assembly once the heater assembly is out. once the heater assembly is out this is a no brainer. i just want to make sure i dont have to start removing the dash/radio/etc...
is this correct (for a 75 merc bobcat)? how much time is involved in this assuming im reasonably mechanically inclined?
