I'm not sure how hard it is to get at on your Granada, but these are usually a pain to change.If you were thinking of getting a used one out of something else that will fit I would get a new one put in instead.It will save you grief down the road.If money is tight just join your heater hoses together and bypass the heater core for the summer until you have the cash to get a new one.

they're not hard to change. I did one in a granada I had previously (not project sleeper) a long time ago as it was leaking. bought the part for only like 50-60 bucks Can. and installed it in like half hour tops. Might be harder to find one now but they should still be avail.
