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.

The best electric opener by far!
Color: Stainless Steel, Size: 4-in-1
This is the 3rd or 4th opener I've purchased in the last two years. This is by far the best! Top reasons this is the best:
#1: it has opened every single bottle I've tried - even ones the other struggled with
#2: press the button and let go; you don't have to hold the stupid button in (great for folks with bad thumbs)
#3: I like the light
#4: Battery level indicator and battery life
ALL THIS translates to great value, ease of use, great cork removal
The only thing I didn't like is that there is no stand per se (it rests on the foil cutter). Easily solved with several stands from the other inferior openers

Highly recommended for wine lovers☝️
Color: Stainless Steel, Size: 4-in-1, Color: Stainless Steel, Size: 4-in-1
I recently purchased an electric wine opener, and it has completely transformed my wine-drinking experience. This sleek gadget effortlessly uncorks bottles with just the push of a button, making it perfect for gatherings or a cozy night in.
The design is user-friendly, and the built-in LED light helps guide the process. I particularly appreciate how it works on various cork types without damaging them. The battery life is impressive; I can open several bottles on a single charge.
Cleanup is a breeze, as the device is easy to store and doesn’t require any additional tools. Overall, I highly recommend an electric wine opener for anyone looking to enhance their wine experience with minimal effort. It’s a game-changer!
