Engine Air Filter

Ok...someone tell me what I am doing wrong or overlooking. The air cleaner housing has 3 small clamps on the front. I cannot feel any on the back. But something is holding the lid on, and I cannot budge it. It feels like the back is secured, but I cannot tell how. What do I need to do to get to my filter?

Did you try to raise the side that is clamped by itself, the back has notches the cover slides into

Lift the front with the clips a little then push the cover back. The back has grooves that lock onto tabs in the back of the bottom of the housing

Halfprice is right. But it can still be a pain. Mine has a flex conduit running over the top making it aggravating to get the top off.
I'm so going to change that box out to an open element K&N soon!!

Yes its a pain but you only need to open it far enough to remove the old filter and put new one in

Thanks everyone. I assumed there must be some tabs in the back, but I just could not feel them. I give it a harder wiggle and pop them loose.

Well, looks like the only option here on the 30.1. I even opened the doghouse but NOPE. Wiper motor doesnít look like to bad of a project. Oh well guess Thor thought air cleaner would last forever. Guess Iíll clean dusty engine Shoot itís spring cleaning time here in Florida. Lol
Thanks
Stay safe

On my Towed Escape you have to pull the air filter to change the battery, engineers often just make things fit, not necessarily in a convenient way

On our old Chrysler Sebring the battery is accessed by the driver wheelwell, easier just to remove the wheel.

Yup, they want the service dollars too. Guess itís a crime to work on your own vehicle.

Stay safe

My 1974 Chevy Monza, small V-8, had to release a motor mount and tilt the engine with a jack to change spark plugs.
Later years they had panel in wheel well you could access the plugs with the wheel removed.

Hey small world I had. 1975 2 + 2 Monza V8 too. You got it undo motor mount jack up engine. Remember it well. Car had itís other quirks too. Itís funny try and find one now. Not even collecting material. Horrible design led to itís death. Chevy had some clunkers. I actually enjoyed mine for a while
Guess Thor engineers went to Chevy classes. Lol

Stay safe

I had an old post regarding the replacement of the engine air filter on my 2013 ACE 30.1 V10 engine. Look down the post attached and check the pictures and diagrams for the notches in the rear lid of the air box. It might also apply to other coaches. Once you release the front clamps you have to slightly lift and push the air box lid straight back hard to release the rear as I recall. Once you replace the air filter make sure you properly replace the air box lid at the rear first to make a proper seal.

Thanks Javelin, not sure of change since 2013 but cover would not go back on. Not a tap issue but clearance issue with wiper motor. Removed motor, less than ten minute job. Had all kinds of room. Lid on an off easily. Re installed motor all set. Looks like when the recall on the wiper systems was done by previous owner, whoever installed motor messed up location. Or the factory put motor there in 2015 when unit was built on chassis. Pretty lame

Thanks stay safe

Glad the motor removal option was workable for you. My 2013 ACE has not required any changes to the wiper motor or linkages (so far) and passed its Thor recall for ďinspection on the wiper systemĒ a couple years ago. The OEM wiper motor clearance to the air box top is very tight, so a larger replacement motor could cause problems as you found out.

At least you have Florida temps to work on it; we have about -47F today in Alberta with wind chill. Might have to wear long pants instead of shorts to start the barbecue today.

Thanks again. Enjoying an 84 degree F day here. Thinks thatís 28. Something C . Yikes -47. Well start the barbecue early and keep the lid on.
Not sure but my wiper motor looked like the original mount. Paperwork said it passed the recall. Other than our generator fiasco (resolved) we are very pleased with our 2015 ACE 30.1. Got 53k on her but sheís kept like new. Wish COVID was more under control. Canít even get a site in Florida. Guess everyone is fleeing here. Just got our first dose of vaccine so itís a start. My wife an I miss being on the road exploring. Soon I hope. Stay warm and safe. Hear Alberta is beautiful. Well not in winter burr. Gonna visit someday.
Regards Luke
