Are there any photos of silicone heater hoses in all their glory?

It's not that serious. I was hoping for the motivation! :wink: I want to see if it is worth it to get the silicone hoses, somehow fit them onto the old heater junction lines and install. But I think I'm just going to have to bite the bullet and get new OE heater hose lines. I spilled so much brake fluid onto the hoses when I replaced my master cylinder...

I know you can bypass it all, but I don't trust my finesse skils!

I used to be a strong proponent on this forum for gutting the coupler and using generic heater hoses. I still think it is a good solution in some situations but I've gone back to using the OEM lines on the car we drive the most (the V70).

erikv11, that's what I'm thinking. It is my wife's car after all... Thanks for the insight.
