The heater hoses are fed from a hole right behind the driver seat but in front of the wheel well. The heater gets its heat from the antifreeze running through the engine.
I pulled the hose through and cut it to drain the antifreeze. It took two five gallon buckets so have them ready.
I then took a portion of the hose to home depot and matched up some black metal pipe fixtures. The object is to route the antifreeze out from one hose and back into the other so it can circulate through the engine.
This is what it looks like all put together.
I was able to bolt it right to the wheel well fender to keep it up and out of the way.
