11537639998 - Cooling Water Pipe & Factory wholesale

The part number 11537639998 refers to a cooling water pipe used in some BMW models. It's typically a component in the vehicle's cooling system, designed to direct coolant (water mixed with antifreeze) through the engine and radiator to regulate engine temperature and prevent overheating.

This specific cooling pipe might be part of a larger system, often connecting various components like the thermostat housing, water pump, or radiator. The pipe is usually made of durable materials like plastic or metal to withstand high pressure and temperatures within the cooling system. Over time, these parts can become brittle or crack due to heat cycling, so it's important to replace any damaged parts to maintain the cooling system's effectiveness.

If you're replacing this part, ensure that the new pipe is compatible with your vehicle's make, model, and production year. It is also recommended to inspect associated components (hoses, clamps, and seals) for wear, as they may need to be replaced as well.
