Update: this part sort of sealed/welded itself in place after installation & running at operating temperature. No leaks have occurred.OEM filler neck fits very snug on the radiator fill tube & includes a rubber O-ring. This replacement part is loose and does not include an O-ring. Not sure why there is no O-ring or why it is not a tight fit. Looks exactly like OEM part with two return/overflow lines & same lock-collet on neck. I re-used OEM O-ring with new part. I suspect this part may not last very long.

This new part does not fit properly on the neck of the radiator. It's too big and leaks..The inside diameter of this new part is much bigger than the old one I took off .. it doesn't seal and it leaks... I don't recommend purchasing this part because it just does not fit tightly and it will leak.

Looks right, but doesn't fit.OEM doesn't use a plastic collar. Instead the OEM part is friction fit, but has a groove inside for an.o-ring.This product uses a plastic collar, and it is too loose. The part wiggles and doesn't fit securely, so it leaks.

The fitment is way too loose, causing the coolant to leak out from the joint, connecting the filler neck to the radiator
