Drive Belt Help
I am going to be replacing my belts but have one question. Pretty simple 3 belt setup. Alternator belt, Power Steering belt and Crankshaft to waterpump belt. I have no problem locating the alternator and power steering tension pivot bolts, but I can't see anything to relieve the belt tension on the short belt that runs centre pulley from the crank to the water pump. Whats the trick here? Any help much appreciated. Thanks.

One way is to start belt on pulley and bump starter.If it is tight it can tear belt.The way I do it is remove crankshaft pulley-put belt on water pump then around crank pulley and bolt back up.

All I could see was to remove the crank pulley as well. Gotta do what I gotta do I guess. ( and no I won't be adding a/c...lol...I'll scrape my knuckles to keep the power I have.)
Thanks.

Am I understanding this thread correctly or am I stoned?
Are you asking how to adjust/install the belt that runs between the crankshaft pulley and water pump pulley only????
There is no belt for just those two!!!!
Water pump is run by the alternator belt.
If you have a two groove crank pulley, the outer groove runs the power steering only. The inner groove runs the water pump and alternator.
If you have a three groove crank pulley the middle groove also runs the water pump and the air conditioner.
If I've misunderstood your question, just ignore this.
Best,
Greg

Thanks Greg,
My setup is it different. Not sure if its because of the L82 or no a/c. Seem to be several different setups. I know my last L48 was different, but it was an a/c car.
Its a 3 groove pulley(at the crank). Front runs the power steering. Center runs the water pump only. Back runs the alternator.

I'm certain you're mistaken. I can post a picture if you like.
Do you have a two groove water pump pulley?

No worries, we got her all figured out on this end. Appreciate the help.

Your '76 has the identical set up to my '75. This is the correct and only way the belts were installed on these cars. This shows mine with the A/C not yet installed. I hope the pics are clear enough to see.

I just read your post after I posted the pics.
Yes, three groove crank pulley and two groove water pump pulley is correct for your car and the install set up I described.

You have a point. I think somebody added that third belt thinking that empty groove just had to be filled. They have been on the car since I bought it in 2000 so until today I never really thought anything was amiss. Certainly does not require it without a/c. Now you can see why it was such a pain to get it off. It wasn't supposed to be there in the first place. One less belt to put back on tomorrow.
I really like your braided hoses and engine detailing. Looks great.

Thanks Mark,
I went to the Pomona Swap Meet last month and there was a guy selling the complete braided hose kits for like $20. I grabbed two of them and gave one to a buddy of mine. If you'd like one for your Vette let me know. I'll grab one the next time I'm there and send it up to you. They're an easy install and really clean up your engine compartment. They come with either the chrome ends like I got or you can get red ends or blue ends.
good luck with the belts!
Best,
Greg

I think its time to put this thread to bed. I really appreciate everyone's help. Hopefully I can return the favor with some of my limited knowledge in the future.
Thanks for the offer on the braided hoses Greg. I actually have access to them from the race team I work for. Been thinking about going that route, and seeing yours just tipped me in that direction.
