  • RedHot gets a new engine air filter

    For those who may be considering changing your C7 air filter, this might prove to make the job easier (or discourage you). This covers how to replace the OEM ACDelco A3191C engine air filter in a non-Z51 C7.

    RedHot is coming up on eight years this October, and still had its original engine air filter. While the oil and oil filter have been changed annually, and cabin air filter changed per schedule, prior checks of the engine air filter showed it to be in fine condition and not needed to be changed (even at the suggested six year service). I reviewed a number of the YouTube videos on how to do it along with various other write-ups. While most followed similar steps, there were variances.

    I decided to follow the specific steps outlined in the Owner Manual under Vehicle Care, section 10-18 and 10-19. While a lot of cars make you jump through hoops to change the cabin air filter, the C7 cabin air filter is very easy. However, even though I have worked on more than forty different types of vehicles, and carefully reviewed the how-to media, I found the process to change the engine air filter unnecessarily complicated by the tight quarters and placement of the airbox on our C7s. It isn’t actually very difficult, but does require going slowly and taking care, as well as figuring out how to rotate the filter to get it out and the new one back in.

    Here are the steps I followed:

    What I used
    • Fender protector cover
    • 7 mm socket and wrench with extender
    • Torx T-25 head and driver
    • Flat head screwdriver
    • Microfiber towel
    • Portable light
    • ACDelco A3191C air filter

    Removal steps:
    • The first step was to put the fender protector cover down so I could lean over to remove the four 7mm bolts from the hood extractor duct. Note, these are NOT captive, so be prepared to catch each one when it is fully unscrewed (and they are longer screws than you would think).

    Next ease the surge tank coolant black hard plastic hose up from the two retainer brackets on the air filter housing end cap. Treat this hose gingerly- many of the reviews talk about how brittle/fragile it is.

    • Use the flat head screwdriver and loosen the air duct clamp down on the side of the duct (radiator side) where it slides onto the air filter housing end cap.

    • Now slide the red latch on the sensor connector at the engine side of the air filter housing end cap. After you slide the red latch, press down on the latch to release the sensor connector and put it out of the way.

    • Ease the air duct that goes from the air filter housing end cap to the engine off of the air filter housing end cap.
    • Next use the Torx T-25 head and unscrew the two Torx screws at the top right and left of the air filter housing end cap. These two Torx screws are captive and will remain in the air filter housing end cap when you have fully unscrewed them.

    • Now, make sure that the surge tank coolant plastic hose (step 2) is free from the housing, and the air duct is fully off of the air filter housing. Push the air filter housing end cap away from the top (where you unscrewed the Torx screws) and downward. Again, pay attention so that you don’t inadvertently catch the surge tank coolant plastic hose as you do this. Once you have it pushed away from the top, you can lift the housing end cap up to free the two plastic tabs on the bottom of the end cap that are in slots on the air filter box and act like a hinge.

    • This next step takes a bit of visual review and gymnastics: rotate the air filter housing end cap so you can carefully bring it up and out of the engine bay.
    • Now you can see the air filter. Just slide it out and carefully bring it up.

    Inserting the new air filter:
    • I cleaned the edge of the air filter box, though it was surprising clean, with a microfiber towel. I did the same with the air duct. Now just ease the new air filter down through the ‘maze’ and insert fully in the air box.
    • Take the housing end cap and ease it down similarly, aligning the two plastic tabs with the slots on the air box. Once you are sure you have both tabs properly seated, pull the end cap up and tighten the Torx screws. Note, the rubber gasket on the new air filter will seem to be slightly thicker than the one you are replacing because the old one was compressed over time. Because of this you will need to hold the end cap in position while you screw the Torx screws in fully.
    • Now reattach the air duct and tighten the air duct clamp with the flat head screwdriver.
    • Connect the sensor connector- it should click in place. Slide the red plastic retainer home.
    • Now grab the hood extractor and the four 7mm bolts. Take care to ensure you don’t drop any of the bolts in the process. I hand started each bolt until I was sure it was caught and then used the socket and wrench to tighten. Remember these seem to require a surprising number of turns until they are fully tight.
    • Finally, ease the surge tank coolant hose back into the two plastic retainer brackets on the top of the air filter housing.
    • Check all of the connections and screws and you are done!
    Plan on about 30 to 45 minutes to do the entire process (presuming you don’t drop a screw).

    Hope this helps. Please let me know if you have any questions!
