Throttle Body Coolant Lines

N8GTOL

I wouldn't do it to a daily driver. Maybe if you're just going to go track the car on a warm day where the rpms will remain high you could take it off.

I believe the coolant lines are there to keep the throttle body from icing up. Similar in function to the carb heat knob found on older carburetor airplane engines. With respect to airplanes, you can get carb ice on a warm clear day at a low altitude where the air temp is well above freezing (72F). I realize we dont have carburetors in our engines but there can still be a significant pressure drop down stream of the throttle butterfly where ice can form under the right low rpm conditions...ice can also form on the throttle body itself which could choke off the engine. Some really old cars were made without heated throttle bodies and there were a lot of issues that forced automakers to retrofit heat sources onto the throttle bodies.

A simple updraft carburetor with a fixed venture illustrates basic carburetor action. Intake air charge, at full or reduced atmospheric pressure as controlled by the throttle, is drawn into the cylinder by the downward motion of the piston to mix with the unscavenged exhaust remaining in the cylinder from the previous combustion.
