Taking her into the dealership for a super charger coupler replacement 55,000 miles. We got marbles on start up. I'm under the impression the supercharger is removed. While they are in there what plastic items should be addressed?
Thank you in advance for your time.

The blower does not need to come off for snout replacement. It's a quick and easy job. An hour maybe?
You ARE at the mileage (and well past the age) to have a LOT of things replaced or checked.
Check the mileage maintenance chart and add tranny fluid and diff fluid to that list. EVERY fluid, actually.

 

No supercharger removal should make the visit less painful. All fluids changed many moons ago. Without removing supercharger is my question mute? Will track down the mileage maintenance chart.

 

The snout is easy, the entire intake removal on a 4.2 is a total bear I don't ever want to do again. No benefit to removing more to get at things MAYBE not needed yet. The snout does not need removal to get at the hoses below, so that wouldn't help anything.

Yeah, just check the list and go from that.

 

Do the supercharger oil while they are in there, belts and idler pulley. Valley hoses are a consideration as well (big job). The 3 legged plastic hose that goes to the side of supercharger cracks with age.
