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

[rick3000]

jsceach, thanks again for the reply/information. My dealer question, was more rhetorical, because Porsche used to sell OEM center radiator Y hoses that fit on the base car with no modification, and I am curious what they do when someone with one of the OEM kit's comes in for a repair and the Y hose sized for the base car is no longer available.

I have a 2.5L base and have been having an overheating issue, which I am fairly confident is either a bad thermostat or water pump. I am about to change the water pump, and install a low temp thermostat, and decided while I have the coolant drained from the car I would also like to install the center radiator to keep everything running as cool as possible.

I track the car a few days a year, but I am primarily interested in keeping the coolant (and in turn oil) as cool as possible to help keep my engine healthy over the long term.

Thanks again for the replies!

hey rick3000; I also have a base 2.5 and can understand your concern. With temps 100+deg and climbing hills in the twists I see my temps occasionally touching the right edge of the 0 in 180. I have a freshly serviced cooling system, LN low temp, New OEM WP and cleaned radiators. My temp in same ambient conditions when driving on freeway are on the left edge of the 180 hash mark. Not to steal the thread but do you currently have or have you considered the S oil cooler? This would be much simpler and perhaps cheaper than the radiator mod and since would have a direct effect on oil temps, may provide the additional cooling needed. I am considering installing one on my car.
