85MM Throttle Body Install Notes

[panelman61]

I finally received my 85mm Throttle Body this afternoon. SO then I read up a little bit and wanted to see if it really that easy to change. I disconnected the battery during the install so the PCM can re-learn it. All there is to it is to:
1) slide the red tabs back on the harness attached to the intake tube and on the throttle body itself.
2) Push down gently on the black tab in front of them and slide it off.
3) Next take your flat head and loosen the clamp on the intake tube.
4) Give it a little pull and set it on top of the engine cover.
5) Now pull up on the front of the engine cover a little and lift it up enough to get the throttle body out.
6) Loosen the four bolts on the throttle body with your 1/4" drive 8mm socket with an extension.
7) Pull the throttle body out. (don't drop the screws).
8) Make sure the rubber O ring is in it's groove.
9) Place the new on on there and make sure the pin on the intake guides it into the correct place.
10) Put it all back together (the intake is plastic so just snug the screws down or you'll strip it) and drive it for a little while.

Total time investment: no joke 10 minutes.
Tools needed: a 10mm wrench for the battery cable, a flat head screw driver for the intake clamp, and a 1/4 drive, 8mm socket with extension for the throttle body itself.

Once I decide on tuning and an intake, my 87MM will be soon to follow. Thanks for the notes!

The throttle body on mine was the easy part and yes about 10 min is correct, however I put on the Vararam intake and that is another story.

Good write up, steps 8 and 9 are what most everyone get in a hury about and the orange o ring slips out of the housing or they do not fully seat the plug for the TB

Sounds the same as what I did except I did not disconnect the battery. I do not remember the O ring part but I probably did it otherwise I would have run into issues already. Should I have disconnected the battery I noticed a huge gain without disconnecting it?

I had'nt noticed the oring before, and wanted to make sure I had installed mine correctly, so I checked tonight. My o-ring was white.
Great Coles notes for the install; it's as easy as you may imagine.

I just put the O ring note on there just in case. And disconnected the battery just so it could re-learn the new one. Neither is really a big deal I think, but I just wanted to make sure nobody had any problems afterwards. It's so easy a caveman could do it.

And majority of this 10 mins is finding the right socket and extension to get it done and putting your socket away...LOL
Install is probably 1-2 mins


Anyone need a ported throttle body we have some 85mm and 87mm in stock and ready to go out

Who knows the size of a stock TB from jeep Grand Cherokee srt8 2008? Will it fit 5.7 Hemi?
