Nope, still got my replacement in the box, but if you have those sprung steel clamps vs the "ideal" screw type clamps....go & buy the special remover tool, the up-scale one at that...it has the grasper on the end of a long cable...you'll need it & it will make life a bit less stressful, fighting with the hose clamps, that is if your 91 used the same clamps as my 90.
Not knowing the FSM steps, I haven't looked because I don't relish doing it...it would seem to me that the fans at least would have to go for the job to be even remotely pleasant. I could see r & r'ing the rad too, as it isn't that bad, just to have more room to stick my fat head in there to see what I was doing. Might even have to dis-mount the steering cooler for some room & the tensioner, p/s pump, jez...this seems like fun. I think I'll shut up now.
Oh yea, I hear ya about the unheated garage.....I got no heat & no recepticals in mine & the overhead light stinks. You have my empathy, I hope it goes smooth for ya!
