G50 hose question

[Chuby]

I just got finised with some under plenum/valve cover work and cannot for the life of me figure out what to do with the two port that are just forward of the EGR valve on the plenum. Any suggestions?car is a 90 G50 standard

It looks like you may be talking about a coolant hose hidden under the EGR (5th pic down) and I'm not sure what else. Hopefully the link and pics will help you sort it out. Good luck.

I am guessing by that link it runs coolant into the one side then back out the other and on to the TB?

Hey Chuby, there will be a small coolant line that connects on the left side of the throttle body (assuming you are standing over the drivers front fender)and another small coolant line that connects the right side of the throttly body to the plenum itself (side facing you) in front of where the egr bolts up. Another coolant line under and in front of the egr bolt up area again on the plenum itself is the coolant stream outlet which terminates into the engine valley. This stream of coolant is supposed to locally bring down the temp on the throttle body and the egr passage. These lines are very easy to forget to reconnect.....I did exactly that when I did my plenum job. Hope this helps. Boris P.
