The Subaru WRX average ($101) runs 19% above its median ($85), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 10 model years for the Mercedes E Class (2015–2024) but only 8 for the Subaru WRX (2015–2024), so the Mercedes E Class data reflects a broader range of generations.
Only 38% of Subaru WRX water pump listings include a posted price (178 of 472 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
At Grade A (excellent) condition, the Subaru WRX is 43% cheaper ($85 vs $149) — the gap widens compared to the overall median difference.
Buyer's checklist
What to check before buying a used water pump
- Spin the pump pulley flange by hand to check for smooth bearing operation, grinding noise, or shaft play (a new pump is usually recommended due to low cost).
- Inspect the weep hole on the pump body for blue/green coolant residue, crusty mineral buildup, or active leakage signs.
- Check impeller vanes (plastic vs stamped steel vs cast iron) for corrosion, missing fins, or detachment from the shaft.
- Verify housing bolt patterns, thermostat housing integration, and belt pulley hub offset relative to engine accessory drives.
