The Stovebolt Site Forums The Shop Area Engine Shop GMC 228 Water Pump & 5/8" Pulley

I'm trying to located these replacement parts which have been discontinued. Any suggestions as to where I might find these parts would be appreciated.

Thank in advance for your help.

They are out there- just cruise the net- try Summit Racing equipment to start, just saw one on there. Looks like the going rate is between $85 and $115. I believe the 228, 248, 270 and 302 all take the same pump, makes finding one a lot easier, someone correct me if I'm wrong. In my search for one for my 248 I noticed pulley sizes varied.

Thanks for your reply Idaho!

I'm still not having much luck. Many web sites list them; however, when you try to order they are unavailable. I spoke to several parts stores and even Cardone, they confirmed the pump has been discontinued. You are correct on the application for several engines; however, they all come up discontinued or no longer available.

Thanks again.

I wound up getting one from a fellow forum member, let me see if I can find his business card. He may have another one. Another option, I called NAPA, they told me they could get my pump rebuilt for me, I never persued that option. Ill continue checking around for you. You should continue watching Ebay for one, I have recently seen the parts to at least rebuild your pump if you can't find a new one.

Here's an update as to where I'm at on this dilemma.

The pump was recently rebuilt, and when I got it back the pulley was damaged. The damage must have occurred during the shipping process. The company that rebuilt the pump is trying to make it right for me and likely will attempt to have the shipper reimburse them for the damages. They are having an extremely difficult time locating a pulley with a 5/8" groove.

In the meantime, I thought I'd try to locate another pump w/pulley to have as a spare.

I'll let you know how this plays out!

Thanks,

Have you tried Jim Carter he lists them, as fitting 228 and 248 motors with the (note) correct pulley size of 7/8"

Are rebuild kits available?

I'd like to know either way as I have a 50' 228 motor, and would like to rebuild the water pump (I've just rebuilt the dyno)

Thanks for your reply.

Yes, I have tried Jim Carter. It is my understanding they no longer stock this item.

I found several companies that will rebuild these water pumps for $115-$175 plus shipping. These companies have slightly different warranties, so be sure to ask about their terms and conditions.

Thanks again,

Any luck on finding out what to do with these 228 water pumps? I'm having a similar problem locating the water pump. I've tried everywhere from Parts Train to Jim Carters. So if I could get any help it would be appreciated!!

Thanks in advance

Would you be able to rebuild your own pump, or have someone else do it for you? They are available on Ebay for 35.00. I bought one and followed the shop manual and did the rebuild myself. You will be reusing your old pulley. These are old kits and the gaskets were very dried out, so new pump gaskets will need to be found. Type in "water pump rebuild kit GMC".
They fit all pumps on 228 through 302 from 39-62, except maybe some military long shaft pumps.

I just rebuilt one last week. Just be careful to follow the directions when pressing the old bearing out and in.

I sent my water pump in to Hite Parts Exchange, Inc., they're in Columbus, OH. The rebuild was $115.00 plus shipping and has a one year warranty.

I just got it back a few days ago and hope to install it this weekend.

Now I can't find the rebuild kit. This is about to drive me insane. It's the last thing I need to get my ol' girl on the road for the first time in 25 plus years. Are there any other water pumps that are compatible?

The pumps are supposed to work on 1939-1959 GMCs; however, I was unable to locate one after many hours on the telephone and internet. I don't know were you can find the rebuild kit.

I just reinstalled my rebuilt pump. Next is the new radiator!

I hope you can find the rebuild kit, if you do, let us know where you found it.

Rockauto has 248 water pumps for about $106, but they have 3/8" grooved press on pulley.

Andrew I sent you a message.
tlclerman - will that pump work with the 228, I dont care about the pulley either Ill remove mine and put it on that one or find a belt that works.

Tony,

I do not know if it will bolt up. Maybe some will respond who earlier posted it would bolt-up.

You may want to try www.cardone.com they list these pumps by year as rebuilt. Search under GMC then Truck then Year. You should find part numbers like these for the pumps 59-8013 or 59-8122 there are others.

Just for you guys information, I found a place. A little pricey, but they will rebuild the water pump for you if you want or you can just purchase one. I dont know what it costs to just have yours rebuilt but I bought one and it was around 200 shipped. I just have to return my old one.

Google Dan's Classic Auto Parts.

Couldnt find a new or rebuilt water pump for a 248 six either. Took the advice of a poster here and sent mine to Hite Parts Exchange, Columbus Ohio. $105 with return shipping. Had it rebuilt, and it was back home and installed within a week.
