flames4life Posted August 30, 2015 Report Share Posted August 30, 2015 Does anyone have a diagram of the coolant flow path? i am just curious about a few things with my throttle body rotation. And i want to make sure everything flows correctly. Link to comment Share on other sites More sharing options...

flames4life Posted September 2, 2015 Author Report Share Posted September 2, 2015 Here is my setup now with the rotated throttle body.the coolant line coming from the bottom of the intake is t'd off and runs to the heater core and to the water pump as it would normally. the line coming from the head that usually goes to the heater core and the throttle body now just goes to the core. Are there any issues with doing it this way? when the heater core is closed what happens to the coolant coming from the head? Link to comment Share on other sites More sharing options...
ucw458 Posted September 2, 2015 Report Share Posted September 2, 2015 You may get uneven cooling to the back of the block. There's a metal bypass line that goes from the water pump around the back of the block and connects to the heater core and intake. That draws coolant from the back of the block to the water pump. Without that the coolant can be somewhat stagnant back there. That could lead to overheating the #4 cylinder. Link to comment Share on other sites More sharing options...
flames4life Posted September 2, 2015 Author Report Share Posted September 2, 2015 i have that line going from the water pump to the heater core and intake. just like it would be factory except i dont have coolant running through the tbi only the intake. but where does the coolant go when the heater core is closed? that metal line coonnects to the lower part of the intake where i have it right?

ucw458 Posted September 3, 2015 Report Share Posted September 3, 2015 The metal line connects to the intake and heater core so coolant can flow when the heater valve is closed. Link to comment Share on other sites More sharing options...
flames4life Posted September 3, 2015 Author Report Share Posted September 3, 2015 yes but where does the coolant flow out of the head? when the heater core is closed. not the line that is t'd off. Link to comment Share on other sites More sharing options...
ucw458 Posted September 4, 2015 Report Share Posted September 4, 2015 Out of the intake, right next to the head. Link to comment Share on other sites More sharing options...
Funky Phil Posted September 4, 2015 Report Share Posted September 4, 2015 (edited) So you just replace the facoty metal tube with a rubber hose? UCW, It looks like he has the bypass set up as "T". If anything I think it will just affect the heater. Prolly be fine. I wouldnt run a rubber hose under the manifold though.

flames4life Posted September 5, 2015 Author Report Share Posted September 5, 2015 i only have the rubber line on there until i get or make a hard line. im just trying to understand where the heated water from the last 2 cyl. goes when the heater is closed. because that coolant comes out on the line that is not t'd.

Funky Phil Posted September 6, 2015 Report Share Posted September 6, 2015 It comes out the front. As long your using the bypass port, coolant is always allowed to leave the head when the Tstat is closed. Link to comment Share on other sites More sharing options...
Funky Phil Posted September 6, 2015 Report Share Posted September 6, 2015 Its when the bypass is eliminated that an issue may occur. Link to comment Share on other sites More sharing options...
