The integrated polypropylene tether stays attached to the reservoir to keep the cap from being lost during future coolant top-offs. Important Notes: Verify the reservoir neck on the overflow bottle measures approximately 35 mm in outer diameter before ordering.

• Outer sealing plug diameter 35 mm (1.378 in) with 5.3 mm sealing height - verify the reservoir neck on your overflow bottle matches this dimension before ordering, as some mid-cycle production years use a larger neck.
• Replaces OEM part numbers MR597536, MR597327 and 1375A026, three interchangeable sister part numbers for the same physical cap. This is an aftermarket coolant reservoir cap, not a genuine part.
• Compatible with Mitsubishi: Outlander 2007-2020, Outlander Sport 2011-2012, Outlander Sport 2016-2023, Lancer 2008-2017, Galant 2004-2012, Eclipse 2006-2012, Endeavor 2004-2011, Outlander PHEV 2014-2022.
• Molded from heat-stabilized polypropylene with an integrated tether, this antifreeze reservoir cap resists under-hood engine heat, unlike cheap washer-style caps that warp and melt. Matte white to match the factory part.
• Non-pressurized atmospheric cap for the secondary coolant overflow bottle only, not a pressurized primary radiator cap and not for turbo systems that need a pressurized cap. Single cap.
