Installing the XL Premium oil cooler kit #62996-07 on my 08 Sportster Roadster.

Pretty straight forward but the instructions seem to be contradicting.

The instructions state..' attach the oil return hose to the 'inboard' connection of the oil cooler'

and..'attach oil feed hose to the outboard connection of the oil cooler'

The 'inboard side' to me means the side of the oil cooler closest to the frame (where the clamp is) and the 'outboard' means the side furthest away....pretty straight forward, or so I thought!

But when I refer to the service parts which has a drawing of the unit and its connections, it shows the supply hose connecting to the inboard (clamp side) of the cooler and the return hose on the outside!!....the opposite to the written instructions.

So which is it?, or does it not matter?

Would I be right in thinking the cooler unit does not have any check/return valves so the oil can flow freely either way?

 

It doesnt matter the oil will flow either way.

Thanks. Thats the answer I was hoping for

 

Yep- the flow isn't directional, so connect them whatever way is easiest.

 

Now that you have a cooler check this out........
