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.
- The Theta II engine family spans 2.0–2.4 L in naturally aspirated and GDi configurations. All variants listed share this water pump.
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 — do not reuse old gaskets or seals.
- 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.
- 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.
- 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.
- Are there other variants of this water pump?
- This listing covers SKU WA037 for Theta II engines. For Gamma-family engines (1.4–1.6 L), see WA035 or WA036. Search “water pump” in our store for more options.

The best little helper!
Size: eufy L60 SES (renewed)
I've never owned a robot vacuum prior to this, and was somewhat curious on how it would work, and what it would really do in my small home. I got the L60 refurbished unit, and it came in a brand new box and it looked brand new when I removed it from the packaging. I charged it up, setup the app and connected it to Wi-Fi, ran a cycle and it was all so easy. It mapped my home and it is was off! It does an absolutely fantastic job. I run it daily and can notice just how much cleaner my hardwood floors are.
We have a cat who is intrigued by it, but it does a fantastic job of cleaning up the litter that is tracked from his litter box. That alone is a lifesaver. I will run it in the morning and at night in cats area to keep the hair and litter completely cleaned up.
So far I've only had a few small issues where it got stuck, twice from items left out, and once from a dirty sensor. You really need to make sure you have things put away and have the areas picked up, especially of cat toys and shoe laces, and once in a while wipe the sensors off if they get really dusty.
I highly recommend this, it truly has been a huge help just in daily pickup and keeping the house clean. Its absolutely worth the money.

Filter is too small for full coverage
Filters are not the correct size, too small. Not worth the risk.
Brush arm bristles were also all bent up.

Filters are the wrong size for the Eufy C10 vacuum
The air filters are smaller than the stock air filter. They will probably work if they are stretched out a bit, but as delivered, are unacceptable. The roller and the sweeper are good. Poor filter fit. Original filter size: 1.75 inch by 3.65625 inch. The filters in this set are 1.25 inch by 3.5 inch. Too small.
