A used Mercedes S Class water pump carries a median asking price of $150, which is 76% higher than the Subaru Outback at $85. Supply also plays a role: Mercedes S Class has 4,935 priced listings versus 146 for Subaru Outback, and more listings generally mean more choices and more competitive pricing.
Grade A (excellent condition) parts make up 89% of Mercedes S Class listings compared to 69% for the Subaru Outback, so buyers looking for top-condition units will find more options on the Mercedes S Class side.
The Subaru Outback average ($115) runs 35% above its median ($85), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Only 44% of Subaru Outback water pump listings include a posted price (146 of 330 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.

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.
