Hey guys Im going to replace the water pump in my 70 cutlass with the 350 and want to know if anyone here knows where to buy from.I tried ebay but there are alot of different brands and part numbers.What are is good cheap water pump and where can i get it?Can be ac or non ac.

 

try here - http://www.opgi.com/c/cutlass/1970/parts.html

I use OPGI a lot - and I know a lot of others on here do to. I am sure you can get one elsewhere, I'm just trying to help you out.

 

I like Rockauto for mail order stuff like this. But there's also something to be said for your local parts store. If there's any doubt about which pump you need I'd pull the old one off and take it to your local parts store to match it. Remember, two of the three lengths are close, but not close enough for the pullys to line up John

 

thats what i found out,pullies dint line up luckily i cleaned it up and returned it but I still dont know which one it is.

Kidcutty, if you still have your old one use this thread to identify which one you need.

Then I wouldn't focus on the casting number, but go into your local autoparts store, NAPA, Baxter, whatever you have that carries a good inventory and try to match it on the counter before taking it home. The main differences will be length. The 1964 had the radiator hose on the other side, then late 1970's (?) had some without both heater hose nipples. Except for those two things all you need is the right length from timing cover to where the pully bolts on. John
