I just bought a new AST and it came with some blue silicone hose and 1.1 bar cap. I was just wonder if I should replace the hoses or stick with the stock ones? Also should I use my old 0.9 bar cap or switch to the 1.1?

I'm also going to be changing the radiator hoses. Is there a how to link for that?

Any info would greatly appreciated. Thx.

 

I would keep the old ast hoses if they are in good shape, and use a 13 psi (.9 bar ) cap.

 

I'll do that.

Thanks for the quick reply.
