I haven't seen to much about replacing the cabin air filter. I replaced the filter on my last truck twice a year as it always had stuff in it from parking under trees when hunting, etc. I used the Fram TrueAir filters from Walmart as they were economical and fit good. 

 

My truck is 16 months old and has over 17k miles on it so I decided to change the cabin air filter. Went to Walmart and no stock on the Fram CV11966 filter. Not in stock at the two Walmarts in the area. The AC Delco CF185, P/N 13508023 is around $55 at online GM parts websites and assume that is the cost at the dealer. Found the AC Delco filter at our local O'Reilly Auto Parts store for $26.99 + tax. Not a steal but is OEM and fit perfect. And made in USA. For the price I'll probably change it once or twice a year. No tools required to take the glovebox out. My last truck needed a torx driver to get the glovebox out.

 

Old filter was blackish and had no debris on it.

I purchase the engine air and cabin filters from Rock Auto for my '23 gas.  

 

Air:  ACDELCO A3244C $26.89 -  I believe the C indicates "carbon" filtration vs standard which is not carbon

Cabin:  ACDELCO Gold/Professional CF1184C is $16.28 (Carbon)

 

Interesting:

The FRAM CF11966 cabin air filter is $3 more than the ACDelco Gold

The AC Delco air filter is orange color foam/rubber portion (Fram?), but so are the Baldwin, WIX, and a few others.

 

NOTE:  There appear to be three versions of ACDelco cabin filters....Standard particulate, carbon, electrostatic

I run carbon and change every oil change. I have recirc on 99% of the time.

After reading a report about CO2 levels reaching above 5,000PPM when driving on recirculation, I rarely ever use it anymore.

 

If you are running recirc 99% of the time, why change the cabin filter so often.

Why would you need or want a carbon engine air filter and where did you read that the C denotes carbon?

There isn't a "carbon" engine air filter.  There is carbon cabin filters.  The "C" on the cabin filter designates carbon.  

 

The A3244C is the high capacity engine air filter for gas T1 pickups.  Its the optional filter on the 1500s, its the standard filter on gas HD.

I believe it is noted on RA website where these air filters are featured.

 Thanks for the clarification.  I assumed fine the cabin filter had a c at end of part number and signified carbon, it won’t be same for sir filter.  After thinking about it, carbon for engine air filter doesn’t make sense.

 

BTW… what is T1?

T1XX = The current generation of GM truck chassis code name.  

 

2019-current (2020-current HD) = T1XX

 

2014-2019 1500 and 2015-2019 HD = K2XX

 

2007-2013 1500 and 2007.5-2014 HD  = GMT-900

 

1999-2007 1500 and HD = GMT-800

 

etc...

I ordered a couple of the carbon cabin filters, CF1184C, from Rock Auto. They arrived and thought it was funny that they were made in China. The plain AC Delco cabin filter that I took out and the replacement were made in the USA.

      OEM Trailer Hitch Receiver - Impact tightened by shop

      By SoCal Angler · Posted

      After my recent rear end bumper damage, body shop has made the repairs and included a new OEM receiver hitch.  I started thinking about how it was tightened...to specs or by hand or ??.  I called the body shop and asked and they said it was tightened by an impact gun.  I said I wanted it tightened to OEM specs.  They said no problem, bring it to shop today and they will torque to specs, which they say is 74 ft/lbs.   A couple of questions,,,,   1.  Should new bolts have been used?  If so, how many are there (bill shows one and four (I assume different areas of receiver).   2.,  Since they torqued with impact gun and now are going to probably loosen and then torque to spces, will that damage/stretch the bolts?   3.  If old bolts were reused (truck has 9000 miles), is that a problem?   4.  Any other things iI may have missed with regard to receiver replacement?   Thanks!

      Defective Brake Pad Wear Sensor?

      By newdude · Posted

      Is this supposed to be in English?  "close to 100 fake, new brake pads sign on the dash board"     Pull the wheels off.  Check the brake pad thickness.  Check the sensors out.  You could have good pads and the sensors aren't in to the worn out position, but have an electrical fault with the sensor or the plug wiring to the sensor.

      Tomorrow I go in for my third joint replacement in jus a little over a year year!  I am not worried about the surgery but I am a little annoyed about going through the recovery process again!  I keep my frustrations to myself as I do appreciate that I am truly lucky.  Knee, hip, and shoulder replacements are routine, safe and improve mobility.  The next couple of days will be slow but every day following will see steady improvement in my mobility.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Practical Application ISO 4406   I think this oil cleanliness thing is going to boil down to ones personal resolve. The information is there but applying it I believe will test your commitment to the machine. Implementation would involve building or buying a prefilter or purchase of an "ISOCLEAN" oil. Then installing a single digit micron bypass system. A good deal of testing and about 99.9% of you are saying at that point....yea.....not my cuppa tea. So what can you do?    You already did the first step. Get educated and leave the bias at the door. Be aware of the its, cleanliness, importance.    Do your own work if you can. Keep the equipment clean. Not just your funnel but the engine bay. Use sealed containers. Think it through.    I believe you will find, as I did, that the tightest absolute full flow filters (Beta 200) will be around 20 micron. That will yield on average a Beta 75 of 10-15 micron. They are few in number by brand and price point. Loose filters are a dime a dozen and even the best brands have lines of loose filters. Some cleverly marketed as "Extended Service". Others will market flow over efficiency. But I think the take away once informed is that the extra cost of the best offered is a bargain. There are cheaper filters with good efficiency that are equal in performance to niche brands with big prices. Your Quick Lube is about a 40 micron unit. This is where your dealer is a plus. the AC-Delco filter is a good step up from those places. Even better if you specify the UPF line.    Be skeptical of marketing. Buying an oil that is made from GTL advertised as the cleanest base oil is using a truth to support a lie. While GTL's are made from debris free gas the processing equipment and post handling is just like any other oil. It also ignores the fact that PAO's and Esters are also gas in origin. Any private prescreening testing you would do, and some have done, would yield a result only good for the batch you tested. AMSOIL and Schaeffer's have built a reputation for paying attention to this detail.    Context. Cold starts account for at least 75%, or more, of an engines wear. But of the remaining 25% ish, over 80% is caused by particle count. Now where do we find high milage motors that use this type of information efficiently? OTR trucking!      Now, anyone want to build a prefilter or off line cleaning system anyway?
