BMW Engine Oil Cooler Thermostat Assembly Replacement – Restores Oil Temperature Control – E36 E39 E46 E60 X5 E83 Z4 E85 | Replaces Part No. 17111437362

Restore proper oil temperature control and cooling system reliability with this replacement BMW engine oil cooler thermostat assembly. This component helps regulate oil/coolant temperature management, supporting stable engine operation and helping protect critical engine components from excessive heat.

Over time, factory cooling and oil temperature control components can become worn, brittle, or fail due to repeated heat cycles, pressure, age, and engine bay temperatures. A failing oil cooler thermostat assembly can contribute to poor temperature regulation, coolant or oil temperature issues, leaks, overheating concerns, or reduced cooling system performance.

This replacement assembly is ideal for repairing temperature control issues, replacing aging cooling system components, or completing preventative maintenance on compatible BMW models. Designed as an OEM-style replacement, it helps restore proper system function and long-term reliability.
