Where do I install flush T?

[Cesar Diaz]

Hey folks, Quick question, I bought a peak radiator flush kit and it says to install the flush tea on the in-line hose going to the block and not the one that goes to the water pump… The issue is one of my heater hoses goes directly to the radiator the other one goes to the water pump and then the water pump has a bypass hose that goes straight to the engine… So where exactly do I hook up the flush tea so I can do a flush on my engine?
