11537600584 Thermostat Gasketl For BMW N13 N52 N54 N55 Engine Parts OEM

1. Function & Purpose

• Sealing Function: Installed between the engine thermostat and the engine housing or coolant pipe to prevent coolant leakage.

• High-Temperature & Pressure Resistance: Withstands the temperature and pressure of the engine cooling system (typically rated for -40°C to 120°C or higher).

• Ensures Cooling Efficiency: Maintains the cooling system’s airtightness, ensuring proper thermostat operation and regulating coolant flow.

2. Material & Properties

• Material: Typically made of rubber (e.g., EPDM) or composite fiber, possibly with a metal reinforcement layer.

• Aging Resistance: Resistant to coolant (antifreeze) corrosion, maintaining flexibility without hardening over time.

• Design Features: Precision-molded to match OEM specifications, guaranteeing a perfect seal after installation.

3. Common Failure Symptoms

If the gasket fails, the following issues may occur:

• Coolant leakage (visible pink/blue fluid near the thermostat or under the engine bay).

• Engine overheating (due to coolant loss or thermostat malfunction).

• Cooling system error codes (e.g., BMW dashboard warnings for low coolant level or high temperature).

4. Replacement Recommendations

• When to Replace: Recommended during thermostat, water pump, or cooling system repairs (gasket is a single-use component).

• Maintenance Tip: Use OEM or equivalent-quality gaskets—low-quality ones may cause recurring leaks.

• Installation Note: Clean sealing surfaces, apply coolant-compatible sealant (if specified by OEM), and tighten bolts to torque specifications.

5. Vehicle Compatibility

Fits the following BMW models (partial list):

Note:

• For exact compatibility, verify using VIN or BMW ETK (Electronic Parts Catalog).

• Some diesel engines (e.g., M57) may not be compatible—confirm part number.
