BMW Cooling System
Your BMW’s cooling system is critical to its performance and longevity. Whether you’re driving a 328i with an N20 engine or a 540i with a B58, proper temperature regulation protects your engine from catastrophic damage. At Torrance Motors, we specialize in diagnosing and repairing BMW cooling system problems with factory-level accuracy.
Why the Cooling System Matters
BMW engines operate at high compression and temperature levels, making efficient cooling essential. A failed water pump, clogged radiator, or cracked expansion tank can lead to overheating, head gasket failure, or warped cylinder heads.
Symptoms of cooling system issues include:
- Overheating or rising temperature gauge
- Coolant leaks or low coolant warnings
- Sweet smell from engine bay
- White smoke from exhaust (in extreme cases)
- Engine entering limp mode
Ignoring these signs can cause permanent engine damage. That’s why we recommend prompt diagnosis and professional repair.
Common BMW Cooling System Repairs
We frequently service the following BMW components:
- Electric Water Pump: Found in most N20, N55, and B58 engines. Prone to failure around 70k–100k miles.
- Thermostat: Often replaced with the pump due to shared failure rates.
- Radiator and Hoses: Radiators can clog internally, and rubber hoses may crack with age.
- Expansion Tank: Known to split or leak at the seam on older models.
If your vehicle is leaking coolant or overheating, we begin with a full cooling system pressure test to locate the problem.
