5.0 throttle body

I recently found a hole in a coolant line that runs to the throttle body of my 1994 5.0L. When I tried to replace the line, the brass fitting that it connects to snapped out of the bottom of the throttle body. It appears that this line does not serve a major purpose as it just passes through the left side of the throttle body. I want to know if it will be ok to just bypass this setup rather than replace the throttle body. Any help will be appreciated.

I wouldnt chance it...but thats me. Do yourself a favor and get one from the boneyard. Its not hard to replace, plus you wont have to worry about whats gonna happen if ya bypass it. Your TB might run to hot and give ya problems.

Many people bypass it with no problem. Your air/fuel mixture will actually be cooler, giving you a SLIGHT increase in MPG and/or performance.

I assume that you mean the EGR spacer, not the throttle body. You should not remove the coolant jacket around the EGR spacer if you have a working EGR system because your intake gases will actually be quite a bit hotter. The water jacket is extended to the spacer to cool the hot exhaust gases for recirculation.

It should be easy to get a correct EGR spacer at the junk yard.

I think the coolant line through the throttle body is to keep the throttle from freezing in position in the winter. That can actually happen even if the outside air temp is above freezing.
