[ Fitment ] Fit for Mercedes-Benz E350 3.5L V6 2006-2009, for Mercedes-Benz W211 M272 3.5L V6 (without PZEV Emissions) 2006-2009 radiator hose
[ OE Number ] No. A2115014782, 2115014782, 11733452001 upper radiator hose. Location: top
[ Durable ] Made from EPDM rubber and high-density polyester Fiber, they withstand extreme temperatures (-40°F to 200°F). The radiator hose upper resists drying-induced cracks. Not easy to deform after reinforced construction, not easy to high-temperature softening, not easy to swell, not easy to damage, and has a long service life
[ Leak-Resistant ] The connector and inner diameter dimensions are compatible with the vehicle. The hose has grooves, and the O-ring to the radiator is sealing tightly enough. Avoid gaps or disconnections between the tube and the plastic attachment. The hose size is the same as the old one. Avoid the hose being too long/short; after installation, the hose is kinked. The upper coolant reservoir hose helps resist leaks even at a constant pressure of 50 PSI
[ Easy Installation ] 1. Unscrew the drain plug to drain the radiator. 2. Dismantling old water pipe: Clean the interface groove (residual sealant=source of leakage). 3. Install new water pipe: Apply a thin layer of new O-ring coating. 4. Tighten The Hose Clamps To Secure The Hose. Refill The Radiator Again
