IAC

Post by 85xr » Tue Sep 14, 2010 7:16 pm

i am installing a rotated intake to my new motor, as im sure you all know that the throttle linkage hits the hood liner. so i cut a piece out of the hood liner for the linkage, seems to be fine except now the IAC is hitting. my question is, can the IAC be mounted backwards? doesnt look like it can as only one port goes thru the throttlebody.
have seen pics of others that have it facing forward, but if possible, i would like to face it back.????????? thanks

No you cannot mount the IAC backwards, but you can and should get rid of that hood insulation.

I think you can use the shorter IAC off one of the later fords, as the xr4 one is fairly long.

I asked that question a few months ago about the liner. It tends to sag over the years and people have had issues with their throttle linkage rubbing or getting caught in it. Since you're having clearance issues, why not? It also retains any oil if any was spewing around and can catch on fire. It also retains heat. To me, the hood will act as a huge heatsink if the insulation is removed.
Almost everyone here has done it, so I went ahead and removed it.
In my opinion it cleans up the engine bay, even though its not physically in the engine bay, know what I mean?

I think the shorter IAC was from a tempo but brad or somone else can chime in for sure. I believe that one had an internal diode, so you may need to remove the one in your harness. You can also run the remote IAC from an 80's 2.3 ranger too.

small IAC

I used a 5.0 IAC on my XR, and it worked fine.. dont think that the extra diode will cause a problem as its still sending the power the same direction, someone will chime in if Im wrong!! well it worked for me.
