Title: Hydraulic filter leak?
Post by: Kathleen Schell on June 11, 2021, 05:30:52 PM
What hydraulic filter for the fan and power steering system is correct for a 06 Monterey?  The filter installed 6000 miles ago after a hydraulic cooler replacement is a Fleetguard HF 6505 and I suspect it may not be correct.  On our last trip it stated leaking at the gasket. It looked like the gasket was too thick/tall.  After a mobile field tech looked it over, he installed a shorter gasket and got us back on the road. The owners manual lists Filtri CSG100P10A which in Fleetguard corresponds to HF 6710 not 6505.  Based on the pictures those two filters look like they have completely different sealing mechanisms.  What should be used?  I suspect I have the wrong filter.  Previous posts also mention CSG150A25A as an upgrade and seem to have a similar sealing surface as the CSG100P10A.   I want to go with the right filter and know it must be a quick change out or will have a problem with draining the 12 gallons of transmission fluid in the system.  Has anyone else had these issues?

You will lose some fluid when changing the filter but does not require draining. Check out these two posts RE up sizing the filter.

Kathleen,
The 06 Monterey owners manual in Coach Assist listed the CSG100P10A as the OEM filter for the hydraulic system. It crosses to a Fleetgard HF 6710. Both are 10 micron filters. I couldn't find any listing for a CSG120P10A.

From the earlier post by Lee Welbanks the upgraded filter is a CSG-150A-25A which crosses to a Wix # 51846
Lee is a frequent contributor to the forum and may have some insight on your filter issues.

The filter comes with two different rubber gaskets, if I remember correctly the one I used is the big one that goes into the out side sealing ring.
