MALIBU 💦 water pump

[Dezimade]

Sorry for the delayed response. The HD pump was available in both iron and aluminum, they just used the lighter version in things like the sporty Camaros and heavy Blazers. You'd be fine with either one and there's absolutely nothing wrong with the iron units, I just have a thing for aluminum and figured the lighter the better.

As for it being a serpentine: The serpentine setup we all know and love utilizes a "reverse rotation" water pump due to one belt running everything. I believe these came about in the late '80s. Just prior to that, GM was so smart that they combined V belts and 6 rib "serpentine" belts on some vehicles, using both on one car. The pump I listed is used on some of those vehicles but is still a standard rotation pump and flows the correct direction, so you may see pictures with a 6 rib belt.

Here's the Duralast pump I bough with the rear cover removed showing the high flow impeller with disc.

A long water pump in its natural habitat. Does the space between the engine block and pump look the same as yours?

Here are some standard duty pumps that are quite affordable. From this list I'd select SKP, but would likely use Duralast if it were available locally for the same price.

These are the better versions, and you'll see the model I chose towards the bottom, though they don't have to cost so much. Notice that the Duralast pump above sports the exact same part number, right down to the "GMB". Same part, half price.

A standard volume iron pump from SKP, Duralast, or equivalent will be sufficient for your engine and should last thousands of miles (not just a week) while not breaking the bank. I typically prefer Delco parts but in this case chose Duralast so I could upgrade to aluminum, and have no regrets- if you want to spend the extra money to upgrade I can recommend this pump. It comes with gaskets, bolts, a pipe plug, and a threaded stud to put pressure on the timing cover and prevent cam walking. Mine was missing a gasket. Always buy gaskets.

Great info thanks

Well you got some idea of what you might get .I'm going to suggest a couple relative things seems like your car has a FaN clutch if it has some wear you shouldn't be able to rick your fan from front to rear over say 1/8" movement... and dig up a big screwdriver ( 16") to crock the fan nuts while loosening or tightening them ( visegrips?).you can glue any gaskets to your pump to keep them from moving when you stick your bolts in you might have to take the fan shroud loose or apart as I forget the exact process check the Heater hoses and clamps add any antifreeze as nessesary to cover Temps in any travel Ed winter areas while apart round up a big low drain pan .Check lower radiator hose for rot or oil soak, or occasionally a radiator clamp ( gates) no one has mentioned the king of water distribution equipment the name Gates "for hoses ,clamps ,and even pumps " ! (use)...there THE quality brand name "at a cost of coarse...so if your now thinking gates get it from a wholesaler and thanks for bringing the subject up also if this project gets any bigger we be could looking at radiators and the major improvement of new felpro head gaskets...View attachment 251083
