Vehicle & Engine Compatibility
| Brand | Model | Years | Engine | Drivetrain |
|---|---|---|---|---|
| Volkswagen | Atlas | 2018-2023 | 3.6L VR6 | FWD / 4Motion |
| Volkswagen | Touareg | 2011-2017 | 3.6L VR6 | 4Motion |
Features & Benefits
| Feature | Benefit + Verification Signal |
|---|---|
| Vacuum‑controlled switching function | Faster engine warm-up and optimized cooling — pump partially restricts coolant flow during cold starts, allowing engine to reach operating temperature quickly. |
| 65mm PPS/TFE/ACM composite impeller | Superior corrosion resistance — resists cavitation and chemical attack from G12evo/G13 coolant better than metal impellers. |
| Direct serpentine belt drive | Simplified service access — pump is externally accessible (passenger side), not buried behind timing cover. |
| Precision cast aluminum housing | Excellent heat dissipation — resists warping and cracking under thermal stress. |
| Meets or exceeds OE specifications | Direct fit, no modification — verified by manufacturers such as Vaico, GMB, and URO Parts. |
| 100% factory tested | Reliable out of the box — each pump leak‑tested and flow‑bench verified before packing. |
Quality Control & Verification
| QC Item | Verification Method |
|---|---|
| Housing casting integrity | Visual and pressure decay test on bare casting |
| Impeller balance | Dynamic balancing at rated operating speed |
| Shaft seal leak integrity | Air pressurization test at 1.5 bar — zero leakage |
| Vacuum control servo function | Vacuum applied to control port; verifies full open/close travel |
| Flow rate verification | Flow bench tested at multiple RPM points (batch sampling) |
| Bearing smoothness | Rotational torque check and noise inspection |
| Dimensional accuracy | CMM inspection against OE blueprint for gasket fitment |
| Total functional test | Random 2% of each batch tested on circulation loop at operating temperature and pressure |
⚠️ IMPORTANT: Water pump replacement on 3.6L VW engines requires mechanical competence. Professional installation recommended.
Installation & Maintenance Recommendations
Why this part fails (OEM design consideration):
- Coolant leak through weep hole → indicates internal shaft seal failure
- Leak from pump housing seal/gasket → external leak visible at mating surface
- Vacuum servo failure → incorrect coolant flow regulation, may trigger DTCs
- Electrical connector seal failure (sensor-equipped variants) → coolant ingress into electrical connector, causing false sensor readings and air pockets in cooling system
Recommended Replacement Indicators:
- Low coolant level warning recurring despite topping up
- Visible coolant puddle under passenger side of vehicle
- Coolant residue around water pump housing or pulley
- DTC P2400/P2404 (related to coolant pump vacuum control circuit)
- Engine temperature gauge fluctuating or rising above normal
Packaging & Supply
- Individually sealed in protective plastic bag with anti-rust coating
- Packed in foam-lined carton (branded or plain)
- Note: Gasket and mounting bolts not included — must be purchased separately
- Bulk wholesale: 20 pumps per master carton with dividers
- Suitable for: VW specialist repair shops, independent garages, auto parts distributors
Shipping dimensions: Approx. 20*15*12 cm, weight approx. 1.5-2.0 kg
