Called In about getting an upgraded LMM water pump after being referred by wagler. Molly assisted me after not being able only finding the Upgraded LB7 pump. Molly provided me with the pump # to the LMM pump I had already seen not saying whether it was aftermarket or stock based. I asked her if she could confirm if this was upgraded like the lb7 and she put me on a brief hold. She came back on the line saying this was an upgraded LMM water pump like the LB7 I just needed to order gaskets if I didn’t have any because they were not included. I then mentioned the price difference and that it wasn’t listed anywhere like the LB7 that it was an upgraded pump. She put me on another hold and come back saying this was an upgraded water pump they are new OEM pumps that they take and modify then ship out to their customers. Upon receiving the water pump it was still sealed from where GM packaged it as a stock OEM part much cheaper at local dealer. If your after a upgraded water pump this is not it.

I’d like to say thank you to all at Dirty Hooker Diesel / DHD who helped a lot. It wasn’t the nicest of experiences while the work was going on but the finished job made all the works worth it in the end.

Including studs for water pump would of been a big plus. I had to make an additional trip to the parts store.
