Which Way Does The Coolant Flow On My Radiator For Installing Kat's Circulating Tank Heater

Question:

just to make sure here on the bottom radiator hose there is a tee going into the heater core would this be the one i use with the arrow toward the core?

The coolant in your vehicle will flow from the engine into the radiator via a hose at the top of the radiator, and then out from the bottom of the radiator into the water pump.

That is correct, assuming that you're connecting the Kat's Heaters # KH13150 from the heater core to the engine drain. If there is no drain in your engine block, then you can use a lower radiator hose connector like the # KH28115 to splice into your lower radiator hose instead. The included Y-shaped tube will connect the tank to the heater core hose that leads to your engine block, water pump, or manifold, depending on your application. I've linked all of the lower radiator hose connectors to this answer in the event that you need that part- that part number may not work with your radiator hose, so you'll need to find the correct fitting from that link.
