4.0 belt change and throttle body
Changed the belt today waiting on the draft so I figured I snap a few pics.
The new belt vs. old belt. I'll keep the old belt as a spare.

The tensioner, you can just push it with your hands and some testicular fortitude.


From below.

The new belt seems to work great, no more squealing at start up.
Throttle body is a little dirty. Feels slightly oily, let's hope Takeda doesn't read this. lol But it hasn't been cleaned in over 100k, soooo.


So I think I'll clean it today along with the IAC and MAF. Just need to figure out the best way to do it. I know, I know search. lol Any advice is appreciated.
..and it's draft day so GOOOOOOOOOOOO PANTHERS!!!!!!!

To clean the TB I just got some throttle body cleaner and sprayed it pretty good let it sit for a couple minutes and wipe the crud away. make sure you have a rag below the TB so there is something to catch the drips. Just to worn you it might have been just mine but it took a couple tries to get the engine to start back up after I was done.
I got that same belt its great.

Got everything cleaned up just waiting around to make sure they're completely dry. Stuff really wasn't as dirty as I thought it would be. Now lets see if it'll start now that I've done all this. lol
..and some more pics for the hell of it.



Cleaners I used.

Thats how I did mine @ 40,000. Disconect the battery termanial (-) turn the headlight switch on for 15 seconds and keep the battery un-plugged for a couple mins. Reconnect the termanial with headlights off and it should start right up with no problem.

I let everything dry and got it all reinstalled. Works great!! Idle drops down quicker at start up and my butt dyno can tell a slight difference running around town. Yay for long overdue maintenance!!! Thanks y'all.

i just did the same thing last sunday on my truck. gatorback and cleaned the throttle body with the ford fuel injector cleaner p/n pm-2. it works like the pm-3 but its in a arrosol can and foams up. oh and i also changed my plugs and did the throttle cable mod. i dont know which one helped most but my calibrated butt told me it was worth it.
