Product Description

This Cooltec hose connects the radiator to the oil cooler in selected BMW models, ensuring proper coolant and oil temperature regulation for optimal engine performance. Designed specifically for the cooling system, this molded rubber hose features pre-installed clamps and a plastic quick-connect fitting with a branch port, making installation straightforward for the correct applications.

Compatible with certain BMW F20 and F30 models, such as the 125i, 320i, and 328i, this hose is a direct replacement for the original part in vehicles requiring a radiator-to-oil cooler connection. Always check your vehicle's model, year, engine size, and engine code to confirm compatibility before purchase.

Common symptoms of a failing radiator to oil cooler hose include visible coolant leaks, low coolant levels, overheating, oil contamination in coolant, swelling or softening of the hose, and poor engine cooling efficiency. If you notice any of these issues, inspection and replacement may be necessary to avoid further engine damage.

When replacing this hose, ensure all fittings are secure and the hose is routed correctly to prevent leaks and maintain system pressure. It is recommended to replace the hose at the first sign of wear, cracking, or leakage to protect your engine and cooling system components.
