BMW 17117600520 Engine Cooling Radiator

For inspection and maintenance of the radiator: Reverse-flush the radiator if there is suspected blockage. Clean dirt and debris from the radiator fins using compressed air or a soft brush. If necessary, consult a radiator specialist for a flow test to identify internal blockage. Leaking radiators should be referred to a specialist for repair, as welding or soldering may cause damage. Inspect the radiator lower mounts for damage or deterioration and replace them if needed.
