Simply get a barb fitting to join the two 3/8" pieces of hose together after you disconnect from the TB. Remove the barb when winter comes if you need to and connect back to the TB. Ports on TB don't have to be covered but look better with either the black rubber vacuum covers or a short piece of 3/8" tubing looped behind the TB joining the two ends.

Triathlete - good luck with the electric running cooler than stock - I tried two different shrouded, dual high flow flow fans to pull through the radiator and could not keep it below the stock running temps and consistently ran hotter. There was also a lot of noise and some vibration. A push fan on the outside might be more efficient but there is less room there. I also saw no increase in power with the fan removed. Please let us know how it works out for you though.

Running in 90+ temps with the AC on and a proper mix of 1 year old coolant, never causes a significant rise in tempo. Proper coolant mix and regular replacement is IMPERATIVE for the radiator working efficiently. I have seen a decrease in temps using WaterWetter or the equivalent Royal Purple coolant additive.
