Project STurdteen, Plumbing the Motor and Getting Her Ready to Run!

The Koyorad radiator is truly a drop in piece.   The stock mounts fit perfectly.

With a new engine oil cooler, power steering cooler, intercooler, and a greatly improved radiator, we have increased the car’s cooling capacity by several hundred percent. The car’s previous cooling woes should be in the past.

We replaced the old and weak radiator hoses of dubious origin with heavy duty 4-ply reinforced silicone hoses from HPS. These hoses have greatly improved temperature and burst resistance over the standard rubber OEM type hoses. This is important as we have upped the coolant pressure with the higher pressure Koyorad radiator cap.

The HPS radiator hoses are molded and are a direct replacement for the OEM hoses and fit perfectly.

All of the charge pipes had dubious couplers as well. Some were even single ply rubber, a burst waiting to happen!  We replaced them with 4 ply HPS high-temperature silicone couplers for an order of magnitude more reliably.

An HPS reducer coupler was used at the throttle body. This coupler was previously only single ply and rubber. Why this was used for a boosted application was beyond us!
