Volkswagen MK7 Golf Alltrack Water Pump – Locate Problems, How to, and Tips

The Volkswagen MK7 Golf Alltrack, produced from 2017, 2018, and 2019, is a rugged wagon powered by a 1.8T turbocharged four-cylinder engine. Unlike the standard Golf hatchback, the Alltrack includes standard 4Motion all-wheel drive (AWD), making it suitable for varied terrain and weather. Transmission options include a 6-speed manual or a 6-speed DSG automatic.

A critical part of the engine cooling system is the water pump assembly. On the Alltrack’s 1.8T engine, this part may fail over time due to heat cycles and material fatigue. Whether it’s a coolant leak or fault code, failure can lead to overheating and engine damage if not addressed quickly.

1.8T MK7 Golf Alltrack Water Pump Issues

The Alltrack’s water pump is mounted on the front of the engine block beneath the intake manifold. For inspection, remove the lower engine cover and follow the coolant lines to the pump and thermostat housing. This unit includes a plastic thermostat housing known to develop leaks over time. It’s belt-driven by the balance shaft and contains an electromechanical thermostat. When failure occurs, it's best to replace the full assembly.

1. Coolant Leaks

   Leaks typically occur where the thermostat housing connects to the engine or oil cooler, or where it joins the water pump. These leaks can lead to slow but significant coolant loss.

2. Fault Codes

   Failures may not always leak externally but can trigger warning lights. The most common diagnostic code:

   • P00B7: Low coolant flow/performance

3. Overheating

   In severe cases, overheating can occur if coolant escapes rapidly. If your temp gauge rises above normal, stop immediately to prevent damage.

Replacing the MK7 Golf Alltrack 1.8T Water Pump

DIYers can perform this job, but it involves moderate-to-advanced skill. Expect 6–8 hours of work due to tight access behind the intake manifold.

We provide a DIY install video using a similar VW 1.8T engine with the same water pump and thermostat assembly. While not Alltrack-specific, the procedure is nearly identical. VIDEO

To replace the water pump, you will need to:

• Drain your coolant
• Remove HPFP hard line
• Remove intake manifold
• Loosen balance shaft water pump belt and pulley
• Remove the pump and thermostat housing
• Clean mating surfaces
• Install the new water pump and union
• Replace balance shaft belt and bolt (optional)
• Reinstall manifold and hardware
• Refill and bleed cooling system

Golf Alltrack Water Pump Replacement Cost

• Part Price: OEM or OE water pump kits are available at different price points:

Genuine VW Parts – Best quality, higher cost.

Aftermarket – Budget-friendly, but may lack long-term durability.

OEM/OE (Recommended) – Same manufacturer as VW parts (e.g., INA), but lower price.

• Purchase – Genuine VW Alltrack Water Pump Kit
• Purchase – INA OE Alltrack Water Pump Kit

• Labor Cost: Expect 6–8 hours of labor. Consider carbon cleaning while the intake manifold is off (~1.5 extra hours).

We recommend using an independent VW/Audi specialist for value and experience.

Maintaining Your Alltrack Water Pump

To extend the life of your water pump and prevent costly repairs:

• Check under your vehicle for coolant residue
• Monitor temperature gauge and coolant levels
• Scan for fault codes regularly
• Replace thermostat housing with the pump to avoid future leaks

DIYers can handle this repair with the right tools, but don’t hesitate to visit a trusted VW shop if you’re unsure.
