keith72monte Posted April 11, 2013 Share Posted April 11, 2013 Ok i,m getting my pulleys together, and i find there are a single groove pulley and double for the water pump. I have a small block with air conditioning. i do not have a emission air pump. i see in the assembly manual that cars with air pump use a double groove water pump. I was told by a well know restorer that it should be a double groove pulley. I can see that would be better if the alternator belt was thrown, that the water pump would still operate.I just don't remeber ever seeing a double pulley on any of my montes.But when comparing the two pulleys i have, the single seems to line up alittle better.Since i only see in the assembly manual a single pulley being used, i am going to have to go with that. anyone have a double pulley on their water pump and is a oem setup without a air pump? thanks for any info Link to comment Share on other sites More sharing options...
monte70car Posted April 11, 2013 Share Posted April 11, 2013 Keith I know when I had a/c in my the water pump was a double groove pulley and my power steering pulley was double groove. The crank pulley was a three groove setup. If I remember right we used the groove closet to the motor for the power steering, next groove was for the a/c(we wrapped the belt around the water pump). and then the alt. That was back in 96-97. I think you have the right parts but badly redone parts form the parts store. Link to comment Share on other sites More sharing options...
Sam (Bones) Posted April 12, 2013 Share Posted April 12, 2013 I didn't think monte's used a double groove waterpump pulley??? I know big blocks don't, they used a double power steering pulley, I thought? the small blocks did the same Link to comment Share on other sites More sharing options...
wallaby Posted April 12, 2013 Share Posted April 12, 2013 Not sure about the small block cars; my big-block is just as Sam described. The water pump pulley is a single groove, and the PS pump is double groove. Link to comment Share on other sites More sharing options...
footballubet Posted April 13, 2013 Share Posted April 13, 2013 That's how my small block is set up. Link to comment Share on other sites More sharing options...
70mcarlo Posted April 13, 2013 Share Posted April 13, 2013 Both small-block Montes I've had (with A/C) had a single-groove water pump pulley, double-groove PS Pulley, and three-groove crank pulley. Same for my big-block. Link to comment Share on other sites More sharing options...
