Center Radiator Retrofit - Base to S Hoses, Thoughts on Best Solution?

[rick3000]

Thanks to everyone for the input.

jsceash, what would you say the difference in diameter between the base and S hose is? I would think clamping the bigger hose down would leak, but you are proof to the contrary.

I am leaning toward having the pipes welded, because it seems like the most robust and least likely to leak option. I originally wanted to ask because I have read about both the Pelican step adapter and the Pedro Y adapter leaking or bursting, but having the pipes welded is a pricey alternative (probably $150-ish, still waiting to get quotes). Leaks do not seem common with the hose fittings, but I am getting tired of having to buy coolant, so anything to avoid any possible leaks.

I wonder what the dealer does when someone comes in with one of the old retrofit kits installed that had the y hose sized for the base hard lines?!

There was about 1/8" (3MM) difference.

In answer to your second question if it's not a Porsche part they won't want to touch it (Mine is all Porsche part numbers). With a "Y" metal adaptor your probably on your own they won't have a hose to fit and won't want to be responsible to cut one.

You never did say why you were doing this, and your comment to replacing antifreeze is puzzling. I don't believe before the motor swap I ever had a heat issue, after only in continuous stop go traffic. I never had a fluid loss problem.

If you have a 2.7 that is just running hot, you probably have some other problem that needs fixed and this isn't going to stop that other problem.

Most people who have done this have bigger motors in base cars (my case) or some sort of racing or DE purposed car (also my case 21 day this year).
