The lower hose never gets hot enough to even open the stock tsat.Its the water leaving the tsat that opens it.Thats why its going to the radiator and its HOT.The tsat is 105c it let this temp coolant go to the rad except for the engine warm up bypass.The bottom is the COLD return how could it open a 105c tsat!?
