This product is incorrectly manufactured, the end connector to the radiator does not fit at all. It is too long at the terminal end. It is also very flimsy/poor materials and will not be able tolerate the high temperatures correctly. I was unable to use it. I will be more than happy to ship the product back to you for correct re-tooling on your end to prevent future customers from experiencing the same grief. Competition is tough and you will sell a lot of these if you really spend some more time with the correct specifications and proper material sourcing. Don’t waste your time trust me.

The part fits my 2013 GL450 fine. The o-ring to the radiator is slightly large, or too hard. Have to swap the o-ring with old part. Then it works fine.

Part seemed correct and should’ve worked but one o-ring was swollen and wouldn’t allow that connection to work. Had to return for a refund and purchase the factory ($140) part form the dealer. Factor part went on in three seconds with no issues.
