I recently bought a 1998 honda accord vtec motor 2.3 ltr when i bought it the head gasket was blown valves checked out head checked out no warpage just a blown gasket. car has 200 grand trannys good all in all i didnt think 600 bucks for it was a bad deal. my question is after ive replaced the head gasket im in the process of hooking all my hoses back up and i see an inlet for a hose on the bottom of the throttle body what is this hose and where does it run to? i have a few more questions and i have worked on cars my whole life im 24 and ive been turning wrenches since i was four years old thanks for having me here i look forward to helping other members with their problems and being a part of this forum thanks in advance to anyone who can help me with this

 

Welcome aboard!

There should be two hose barbs on the bottom of the F23 throttle body. One is the inlet and the other an outlet. The coolant goes in through that port in the bottom of the throttle body to warm up the throttle plate.

 

ok. and im assuming this will run to a port on the head somewhere?

 

the one im wondering about is the one that faces toward the firewall. until your comment i didnt pay my tb too much attention but now ive noticed that at some point the barb that points straight out toward the passenger side was broken off. could this have been bypassed in some way before? if so how do i go about undoing that? i want my car to be right im strapped for cash and i need it to last as long as possible

The throttle body was probably bypassed and they went straight to the rotary air control valve (RAC) on the back of the intake manifold, beside the throttle body. I ran my throttle body without the hoses connected to the throttle body for 3 years in cold Canadian winter conditions with no issues. So as long as you still have the RAC valve hooked up you shouldn't have any problems.

 

oh yeah? more money in my pocket check. i really appreciate your help man i couldnt find a hose diagram really anywhere
