Fix the "Mickey Mouse" leak before it strands you.
One of the most common failure points on the BMW N52 and N53 engines is the plastic coolant hose flange (located on the front of the engine block). Over time, the plastic becomes brittle and snaps, leading to instant coolant loss. Our Bevinsee Upgrade Kit replaces this weak link with a high-pressure silicone hose and a precision-machined Billet Aluminum Flange.
Why this is a must have upgrade:
-
Bulletproof Reliability: The billet aluminum flange will never crack, warp, or snap like the original plastic version.
-
High-Temp Silicone: The reinforced silicone hose is designed to handle much higher temperatures and pressures than the standard rubber hose.
-
Perfect Sealing: Includes a high-quality O-ring and a heavy-duty hose clamp for a leak-free installation.
-
Preventative Maintenance: Don't wait for your original flange to break during a drive. Replace it now and enjoy peace of mind.
-
Direct Fitment: Designed specifically for the N52, N52N, and N53 engines found in the 1-Series, 3-Series, and 5-Series.
