Cadillac Catera and Cimarron Forum Discussion, Torx and My Alternator in Past Cadillac Vehicle Discussion; Hello Everyone: I had the unfortunate luck to have my voltage regulator or alternator go on me in rush hour ...
Hello Everyone: I had the unfortunate luck to have my voltage regulator or alternator go on me in rush hour traffic on Friday. I called my parts Guru (Lordo Auto Parts), and he had both in stock (amazing). I opted to go for the regulator thinking that it would be an easy fix. Boy am I stupid. Reading the shop manual many times to make sure I got it right was a smart move though.
Here's where things go off the rails. I pulled everything out of the front of the engine as per the manual, and there she was (alternator), and now it's just a matter of taking out the 2 Torx bolts and I'm home free!! Right!!! There was a Torx bolt on the bottom of the unit and a normal bolt on the other (?) Lo and behold the normal nut just turned without coming out. I managed to find a hole where I could see the Torx head behind the alternator. How the hell did they get that in there without pulling the engine? Is that what I'm going to have to do to get the alternator out? Please say something nice, cause I could use it right now. Cheers, Brian
Pulling the engine is definitely not necessary to take out the alternator. I haven't done it but my father inlaw just did it, twice because he had to remove one from our parts car to replace one on his running Cat. He's out of town right now or i would ask how he got it out.
Just did valves on my 2000 due to a broken timing belt, not related to your issue, but I had to remove that same bolt you speak of.
To answer your question about how they manufacture, they assemble the engine outside the car, and lift it up into the car on the cradle from the bottom. That's how.
As to the bolt, believe it or not, you "can" get at it from the under the car. You can use a closed 12 point wrench, 8mm if my memory serves me, which will hold the torx. You go at it from under the car with your left hand while you use your other hand on a ratchet in the front.
It is "very" tight and you have to guide the wrench with 2 fingers, but it can be done. I did it.
As a follow up to my situation I am glad to report that I did manage to get that $&^( bolt out, but it was a real test of dexterity. As it turned out it was the regulator that was shot. One of the brushes was totally worn out and was making intermitent contact. Thanks everyone for your assistance, it;s always appreciated. Cheers, Brian
