Fuel filter part number is 22937279 which was superseded by 23456595 which was superseded by 23459023. 23459023 appears to be stamped on the latest filters, but 23456595 may be the part number that the dealership needs to find it.

So, here are more or less the steps for changing your fuel filter on a 2014 Cruze Turbo Diesel. I made a couple mistakes along the way and I am sure members of the forum can help clear up a few things that I was unsure about. So here goes:


1. Reverse the car up on ramps so that the rear wheels are on the ramps. There is no need to remove a tire to gain access.

2. Remove the 10MM nuts that hold the belly pan on (on the passenger side of the car). Best to use a deep well socket or extender. You will want to remove the plastic nuts and only loosen the metal one in the front(front of car). Loosening the metal one will allow you to pivot the pan out of the way. After you have removed all the plastic nuts, you will have to pull down firmly on the pan to get it to come loose. (Side note to those wondering about under car washing – there was a lot of salt up under the belly pan, so in order to clean the underside of your car,you will need to remove these.

3. After the pan is pivoted out of the way, you can now use an 18MM socket to open the drain for the fuel filter. OK now, here is where I got confused. Fuel drained out of this, but it never stopped draining. So, after a while, I just loosened the whole housing, and removed it, and the fuel stopped coming out. I did not have a socket big enough for the housing, so I gently but firmly put a pair of vise grips on it,slightly at an angle so that I was able to keep rotating it until the fuel filter and cap came out.

4. Once the fuel filter is out, you can snap it out of the housing much like the oil filter. Dump out any remaining fuel and then snap the new filter in.

5. Replace the big blue o-ring on the filter cap. I gently pried the old one out with a flat head screwdriver.
6. Replace the tiny blue o-ring on the part that sticks the car. I used a tiny glasses screwdriver. I was a little nervous about this one because the new one seemed to fit a little loosely.

7. Screw back in the filter cap until it is snug, then tighten a little bit more.
8. Tighten the 18MM drain plug. (This one seemed a bit fragile so I did not tighten it too much)
9. Turn the key to the on position until you hear the lift pump stop running. Do this at least 6 or 7 times. You will hear fuel gushing and bubbling.
10. Start the car and check for leaks. (Note: I ran mine fora while and then shut it off. I attempted to start it again a few minutes later, but it just cranked and stopped cranking. I cycled the key a couple more times, and it was fine after that.)
11 After satisfying yourself that everything is operating properly, reattach the belly pan, drive and enjoy!
12. Reset the fuel filter life monitor. It's under the Option tab on the DIC. Get it up on the display (the one where it says the % fuel filter life - not the one that says "Change Fuel FIlter".). To reset, push in on the outer button on the turn signal stock - it will ask you to confirm and then it should go back to 100%

I relocated my fuel filter to the engine compartment on the fire wall . I can now do top side fuel filter change as it is on VW TDI's .
The factory fuel filter has a heater built into it as well as a water separator.

Did you relocate the fuel heater as well as the water separator when you relocated the fuel filter to your fire wall?

I wonder if there's a reason why GM didn't put the fuel filter on the firewall? Maybe to prevent fires in a front end collision or perhaps something else related to safety and engineering.

diesel - this is an excellent contribution to the diesel oeuvre.

A quick question: did you get a measurement on the filter housing nut? I'm curious to know the size of socket we'll need. I have a 32 mm one from Snap-On that's intended for oil filter housings. Maybe it'll work.

It's also possible that the O-ring will swell in the presence of diesel fuel.

maybe conspiratorial, but i think they buried it on porpoise, drive more $$$ into dealers pockets...

the duramaxs at work, the fuel filter is in the engine bay, but gotta remove splash shield from wheel well to get at it, so history of chevy burying it.

Maybe it has to do with improving weight distribution? Diesels are already front heavy and moving five pounds back may have been a consideration.

I think it was more like fuggit, put it wherever it'll fit. Of course the consumer will pay whatever it takes to get to it if it happens to be a PITA.

Everything is about $, if it's about safety, it's just because a lawyer said so :)

Engineering is smarter then we could hope to be, but are highly restricted by accounting. Many times it levels the playing field...

All I can confirm is that it is indeed bigger than the one used to change the oil.

I can not help you. Ask the other gear heads here I am sure they can help you.
Sorry.
Manny - I really don't understand why you've offered this as an answer.

You've posted that you relocated your fuel filter and described it as an advantage on this thread which diesel has created to inform others how to change their factory fuel filter.

But you've not answered any questions regarding your considerations for doing so nor even posted an image of your innovation when requested to do so.

Your response is to direct a brother member to address their request to a Gearhead when you know very well that you're likely the only person in the world who has relocated a fuel filter on a RPO LUZ engine and therefore the only one who can respond.

If you truly believe that you've struck upon a superior engineering / safety / cost / convenience innovation that the manufacturer missed than please share your findings with the community, whom you are a part of, by way of a dedicated thread.

In my view, proceeding as you've done here serves to take the focus off of diesel's substantial contribution; which may not have been your intent, but is effectively a disservice to diesel and what he has done for all of us.

Manny,

One of the requirements for the Gearhead badge is a willingness to share knowledge and help other members and to acknowledge when they are wrong. As a community we are still weak on shared CDT knowledge so any knowledge you can share will be welcomed.

It sounds like you may have another How To thread with moving the fuel filter to the engine bay.

The panel you are refering to is the large aero panel that is removed by 10MM socket spaken of on page 1 of this post. I can't find a farther away shot of that panel from a quick search.

I relocated my fuel filter to the engine compartment on the fire wall . I can now do top side fuel filter change as it is on VW TDI's .

I am thinking on putting in a top mounted CAT Fuel Filter were access would be from top side and not on the bottom . I have all the parts and hoses to do the Mod . I just need to make the time in a cold garage ... I know I am a Wuss.....Ahem Embrace The Suck ...LOL I really don't like the location of the stock filter...To bad GM did not learn from VW and MB and BMW and do a top side Oil and Fuel filter access .
Is this what you did?

could you please take a full picture of the panel you had to remove as theres not any on my 2010 2.0 diesel and my local dealer is useless i think this is whats causing water below the rear seat thanks
I will do this as soon as I get a chance to. Might not be until this weekend, as I work from dawn to dusk. But I don't think this would do a whole lot as it's a fibrous material and it does not appear to stop much liquid from gettting through. I think it's mainly for aero and sound insulation.
