Chrysler Repair/2004 Pacifica Cylinder Head Removal


QUESTION: I am trying to remove the cylinder heads on an 04 Pacifica 3.5 liter. I have the heads exposed, and all accessories
Off the engine. The head bolts are out, but the head doesn't seem to want to come off. After a closer look
It appears the inner timing cover might need to come off prior to removing the heads, is my suspicion correct or am I missing something?

ANSWER: Hi Larry,
I just checked the manual and there are a long list of thinks that must be done (about 43 steps!) just to take off the right head and about 24 more for the left head. I would like to send you the pages from the manual that list them all along with some figures you will find useful.
To do that, I need to know your email address so I can attach these pages to an email I will send to you directly. I am not shown your email address by Allexperts so you have to ask a private follow-up question to tell me what it is. Don't use the @ symbol but instead us "at" so the program won't automatically erase the address. There are some other pages that are mentioned which if you want those as well just tell me which ones.

QUESTION: Roland, I scanned the codes and I am getting P0340, would this give an extended crank and loss of power?

Yes, that is the cam shaft position sensor not putting out a good signal and could well explain the performance issue. Check that the retaining bolt is properly torqued (9 foot-pounds) and check the plug/harness connection and the condition of the harness wires as far along as you can. Then see if that solves the problem or not. You can check the output of the sensor to see if it shows pulsing between 5V and 0.3V as you turn the crank by hand with key in the run position. Measure beteen dark blue/gray and dark blue/dark green wires at the sensor (pins 3 vs 2) using fine pins to pierce the wire insulation). Those checks will reveal whether it is the mounting, the wires, or the sensor itself.
