For my 2008 Aspen 5.7L I need to replace a bad MDS solenoid based on the CEL I received. I have everything disconnected from the intake manifold but the intake will not pull off, the front part of the intake is hitting the a/c compressor. Are there any tricks or options to removing the intake or must the alternator and a/c compressor be removed? Just looking for options to save time and energy from removing alternator and a/c compressor. Thanks for any and all input.

 

A/C and alternator have to come off. The A/C you just disconnect and slide to side without disconnecting lines. Their is a small video on Youtube showing some of the process. I found it informational. You can see it here:

 

Thanks for the reply and I agree the alternator and a/c need to be moved out of the way. Here's my notes on removing the intake manifold.
1. I didn't remove the alternator completely. I removed the right side bolt on the alternator and loosened the left bolt and just lifted the alternator up and away like on a hinge. Others may like to remove it completely, but I had enough room just moving the alternator out of the way.
2. For a/c compressor, exactly like Calamity said, the compressor is unbolted and moved out of the way, all lines are intact.
3. To help lift the intake up and out it helped to remove the metal cross member under the windshield cowl, if that's the right part description. This does involve a little additional work since the windshield wipers have to be removed, but I liked having the extra space.
4. Original plan was just replacing the one solenoid, but now going to replace all four. Don't want to have to do this job again, it's a 2008 Aspen with 111K miles on it.
5. Also replacing all the intake manifold gaskets, they are inexpensive and it makes sense since I'm in there already.
6. Final task is a little cleaning before reassembly and then time to get it back on the road.

 

Good evening all. I just picked up a 2008 Aspen 5.7 limited. Loving this truck. Had a 2004 Durango 5.7 slt. So far I added a CAI and Borla xs pro. Looking to upgrade the intake manifold for more midrange power. My issue is that the throttle body, housing on my intake manifold, is located at the back (fire wall) side. All of the upgrade, intake manifolds, have the throttle body housing on the front (radiator side). Will the 392 be a direct bolt on. Is extending the throttle body wiring a problem. I'm sure there are plug adapters (extentions) out there. Thank you in advance for your thoughts and suggestions.

 

Thanks , I got solution of my problem.
