Carl, I bought a heat shield sleeve from LEAF. I think I bought 12 inches and sleeved the radiator hose from the heater hose intersection toward the top of the engine. I highly recommend protecting the hose. I had an issue during taxi tests, and burned a hole in the hose and had to replace it. This hose is easy to remove, but very difficult to get it back on. A sleeve may be easier installed than trying to wrap the hose in that tight space.
