Re: Back With Another Issue
I think the recall was mainly for another issue; the coolant and thermostat housing was originally plastic and was replaced with the current plastic aluminum combination to prevent the coolant passage from cracking.
Perhaps we can all learn from this, and it is a reminder to me also; the problem with OO's car is common if the heater hose has previously been removed by an inexperienced mechanic. The newer manifolds are reliable and last a long time, but they are PLASTIC and will not tolerate somebody pulling with both hands on a heater hose to remove the hose!!
The best way to remove a heater hose, and this applies to the heater core end also, is to slit the hose with a razor knife, after removing the clamp, of course, then gently rotate the hose with channel locks until the bond breaks.
The 4.6 is newer and higher tech than your old Oldsmobile-whatever. You cannot get away with "wrenching" on them like you did with your old cast iron engines.
