Supply also plays a role: Mercedes S Class has 4,935 priced listings versus 374 for Buick Encore GX, and more listings generally mean more choices and more competitive pricing.
The Buick Encore GX average ($133) runs 27% above its median ($105), 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 S Class (2015–2024) but only 6 for the Buick Encore GX (2020–2025), so the Mercedes S Class data reflects a broader range of generations.
The Mercedes S Class water pump is interchangeable across 14 model years versus just 7 for the Buick Encore GX — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade A (excellent) condition, the Buick Encore GX is 25% cheaper ($120 vs $161) — the gap narrows 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.
