If you seen a coolant hose going in and out of the TB, then you can do this. These lines circulate warm coolant through the throttle body to warm the intake charge on cold days and ensure that no air is in the cooling system. For summer time use can you bypass the coolant lines? They carry the coolant to the throttle body and to the idle air control valve under your intake.

Do you realize how much better your truck runs when it's cold, (temp gauge at or below 160)? The coolant pipe now bypasses the throttle body Given that the coolant isnt even flowing through the throttle body before the thermostat opens, and all the metal is heating up just as fast as the stagnant coolant, there would be NO purpose for running the hoses there. Otherwise you can just cut the nub and use some nice hose clamps, not the spring clamps. I'm 90% sure that if you remove the coolant lines to the throttle body the fiav won't be able to adjust idle speed acording to the coolant temp sensor on the thermostat housing. Re-use your spring clamps or order them with the hose kit. This original equipment pipe will provide the same performance, durability, and service life you expect from General Motors. copyright 2020 putneys custom machine. 9) Cleaned the HELL out of the throttle body plate and both sides of the throttle body intake.

Age and mileage make the hoses swollen, spongy and worn. These hoses bring hot coolant through your throttle body and like the pads, assist in cold weather startup. This will prevent a coolant spill when you remove the hoses from the throttle body. Actually it is a coolant passage from the throttle body into the intake plenum. These are the most neglected cooling hoses on your truck. There's virtually no gain by disconnecting the hoses going to the throttle body as air moves so quickly through the throttle body.
