I was changing the coolant hoses on my 2012 N18 Cooper S last week to silicone ones.

I've managed to fit the majority of them, but can't figure out where the two medium diameter ones (outlined in image) go?

Does anyone know?

 

Lots of companies have that 8 piece set, that one i believe is the hose to coolant next on the expansion tanks. Other ones it near that connection on the right facing the engine.

 

I used this diagram when changing the same setup on my N14. That tiny elbow was a PAIN. It goes to the immediate right of the valve cover, about midway from front to back, and kind of under the coolant bleeder screw.

 

On my car the expansion tank pipe is straight.

 

After asking MTC, Forge and Samco.

Only Samco were able to tell me where the two hoses fit.

They fit onto the N14 turbo coolant return pipe. So no applicable to my N18 engined car.

 

Hello everyone, I was just wondering if there really is a difference between high end silicone hoses like Forge and lower end like TT Racing? Or in fact if there's a difference between high end and the ones from China. I figure they all probably come from China anyway. If anyone has had any experience with TT Racing in particular, please let me know.
