Boost Pressure Solenoid Air filter
 

Hi All,


2006 Liberty Limited 2.8L CRD. The maintenance schedule says to
"inspect and replace as necessary" the boost pressure solenoid air
filter. I thought that perhaps this was just a fancy way of talking
about the engine air filter.

Apparently, these are two separate filters since they are mentioned
separately in the maintenance schedule, one right under the other.

I looked up boost pressure solenoid air filter in the FSM and it doesn't
say a damn thing about it except that a clogged one might cause boost
pressure problems.

Anyone know what and where this filter is?

Re: Boost Pressure Solenoid Air filter
 

Update:

I talked to the shop foreman at the local Jeep dealership. This filter
is an in-line filter that resides in one of the vacuum lines.
Apparently, this engine and turbo use quite a different set up than the
Cummins (Ram).

He stated that he has never seen one "go bad". I've never known a
filter to "go bad", but assuming he meant "get clogged up". The
maintenance guide recommends inspecting this item at every oil change
and replacement at 50k, IIRC. The FSM doesn't say anything meaningful
about it that I can find.

I'll post any further information that I dig up for those that own or
work on the Liberty CRD.
