Automotive Cooling System — Replacement Thermostats, Water Pumps, Tanks and Hoses for Mercedes-Benz and BMW
The cooling system keeps the engine at its working temperature and circulates coolant through the block, radiator and heater circuit. VOLLSUN supplies replacement cooling components for Mercedes-Benz, BMW and MINI applications, referenced to the original equipment numbers so the correct part can be matched before purchase.
The VOLLSUN cooling range is organised into three groups:
- **Thermostats & Water Pumps** (10 references) — thermostats, electric water pumps and coolant pumps, including V24001 (OE 2712000315), V24508 (OE 11537550172) and V64005 (OE 2762001301).
- **Expansion Tanks & Reservoirs** (6 references) — coolant expansion tanks and reservoirs, including V67001 (OE 2115000049), V67504 (OE 17117573781) and V67511 (OE 17137647283).
- **Cooling Hoses, Pipes & Oil Coolers** (7 references) — coolant hoses, water pipes, intercooler pipes and engine oil coolers, including V63023 (OE 2712002452), V63629 (OE 17127619684) and V21013 (OE 1121880401).
Each listing states the VOLLSUN SKU, the listed OE reference and the engine or platform recorded in the catalogue. Thermostat opening temperature, pump drive type (mechanical or electric) and circuit position must be matched to the engine variant before ordering; confirm against the removed part and check whether clamps, caps or seals are required separately.

Frequently asked questions
- How do I confirm the right thermostat or water pump? Match the OE number, the opening temperature and the engine code, and confirm the pump drive type against the removed unit.
- Does the expansion tank come with a cap? Inclusion varies by SKU; check the listing and confirm against the removed tank before ordering.
- Do the photographs confirm fitment? No. Images support identification only and do not establish compatibility.
