Coolant lines into throttle body. ACTUAL use...

[JB5587]

My truck is not a daily driver and it is my play rig for the dunes. I drive it around once in a while and it is registered on the road, but not in the rain, snow, mud, etc, and usually just a couple weekends a month. Thought I'd throw that out there before I get the run-ons about cold temps, just leave emissions stuff alone, breaking the law, etc... So on that note, I do not have much for emissions on it. One thing I left alone was the EGR since I'm waiting for my dyno tune for the 5.0 build I just completed, and it wasn't hurting anything. The thing I can't seem to find a for sure answer to is the actual purpose of the coolant line running through the throttle body on the 96 Expo 5.0. Is it JUST there to keep the throttle blade from freezing, or does it ALSO cool any EGR related heat? I would like to disconnect these, but if it cools hot gasses, I will obviously leave it. I personally don't see how it would on my 96 gt40 since the EGR runs behind and off to the side of the lines and the coolant exits before it even sees the EGR, but I want to double check.

Anyone have any input on this?

Nope, it just heats up the throttle body to prevent ice form building up at the throttle plate where the air pressure drops at the constriction.

Just gotta love R718 as a refrigerant!!

Cool. Time to remove them then...
