Fitment Notes
- Always verify the OE part number stamped on your existing water pump before ordering. Fitment data is provided as a guide and may not cover every sub-variant.
- This is the 8-hole flange variant. Some Isuzu engines use a 6-hole flange water pump — count the bolt holes on your existing pump housing to confirm.
Installation / Use / Maintenance Tips
- Drain the cooling system completely before removing the old water pump to minimise coolant loss and contamination.
- Clean all gasket mating surfaces thoroughly and use the supplied gaskets and seals — do not reuse old gaskets.
- Inspect the thermostat, radiator hoses and drive belt while the pump is accessible; replace any worn components at the same time.
- Refill with the manufacturer-recommended coolant type and concentration, and bleed all air from the system before starting the engine.
- Run the engine to operating temperature and check for leaks around the pump housing, hose connections and bleed points.
Common Questions
- Will this water pump fit my vehicle?
- Check the fitment table above and confirm the OE reference number matches the one on your current water pump. If your vehicle and engine code appear in the table and the OE number matches, this pump is a direct fit. Also verify that your pump housing has 8 bolt holes.
- What do the OEM reference numbers mean?
- OEM (Original Equipment Manufacturer) reference numbers are the part numbers assigned by the vehicle manufacturer. They let you cross-reference this aftermarket part against the original to confirm compatibility.
- What is included in the box?
- This water pump is supplied with gaskets and seals required for installation.
- Is Partquip the same as MAP Pro?
- No. Partquip is an independent aftermarket brand. MAP Pro is the house brand of Modern Auto Parts. Both are available in our store, but they are separate brands with their own product lines.

Finally a Place to Store All those Soap Pieces! Self-Lathering, Exfoliating, Good Quality, Love it!
Style: Sport
These soap saver pouches are a really nice upgrade to using regular bar soap and a loofah or washcloth. I love that I can just drop in a full bar, along with all those tiny leftover pieces, and still get great use out of them, while also getting a nice scrub that has a good exfoliating texture without feeling too harsh. It's a medium-like "grit" so just be aware, and both sides feel equally scrubby, and the inner pad material helps the soap foam up easily when you rub it together, making it feel efficient. The three-pack with different colors is convenient for multiple bathrooms or spares, and the little inner loop lets you cinch the opening so smaller soap bits don’t fall out. It does need to be hung to dry since it holds onto moisture, and your soap may go a bit faster because of that constant self-lathering as you use it, but it’s not too bad, and a fair trade-off for how easy and effective it is. All in all, these are well-designed and genuinely useful. Definitely recommended!

Exfoliating, durable, helps bars of soap last much longer.
Style: Sport
Am very happy with the convenience and longevity of this product. In addition the exfoliating properties they really do help make my bars of (sometimes quit expensive) soap in the shower last a lot longer - as much as 3 to 5 times as long. I simply hang it up or place on a shower caddy after rinsing the excess suds off and no more soft, soggy bars of leftover soap laying around. Having tried many different versions of these and I find this style is the easiest to get to properly hold onto any odd shaped or larger bars of soap without the soap accidentally popping out in the shower during use. They also seem to outlast many of the other soap savers. They don’t unexpectedly start unraveling after just a few uses like some of the bath poufs tend to do.

Really good, however, a drawstring to keep the soap inside would be amazing
Style: Sport
I bought these sport soap saver bags and I really enjoy them. I exfoliate with loofah all the time so I did not find the grit of this soap saver bag too abrasive. I found it perfect. I washed and lathered all my parts no problem.
I had a half gone bar of soap I put inside upon receiving these bags, and the lather was amazing. The soap did move around the smallest little bit because it was smaller. I assume with a brand new bar soap It’s much easier to use. But that happens with all of these same design products. A drawstring at the end of the soap saver bag would make this five stars all day.
I would definitely buy these again based on the quality and exfoliation level.
