Hello,
Just finished posting in the New Member Check in.
I have an '07 Wrangler X w/ a 3.8, w/auto. It's my wife's daily driver.
The Jeep spun a bearing and I found a complete 2011 3.8, minus the computer, on-line w/ ~500 miles on it for about $200.00 more than a short block.
My question is, will I need to reset the ECU once I finish the switch and before attempting to start? If so, is it done the same as I've read for the YJ?
One of the mechanics at work (FD) suggested I take all the sensors off the '07 and put them on the "11. This sounds reasonable that the brain would recognize the existing sensors. Also do I need to set the motor @ #1 TDC upon install or will the crank sensor just pick up at the right spot in the engine revolution?
The original is close to being out. A couple bell housing bolts are just too hard to get to, so I'm disconnecting the trans. just so I can access the bolts.
Any appropriate Tech help would be deeply appreciated.
I've always worked on all my own vehicles with very few exceptions.
This is the first motor I've swapped in about 25 yrs. It doesn't appear to just be R&R anymore!
Thanks in advance for any help.
Bill
