Engine air filter 2017 Ventana Le 4037

Need to change the air filter on the engine. I understand it can be a real pain. How do you get access and the correct procedures?

Might be good to post a picture. The rubber boots on mine is what took time, do the distant connection first and use some light spray lube on the outer portion that will receive the boot (avoid getting the spray in the interior of then assembled air system). You may need a 2x4 for leverage. Probably only needs to be changed every 4 years but you will find variation on this, the air minder is a better indicator than age is what I read.

I used a very small flat pry bar to first loosen the clamps from the hoses then loosen the hoses from the air cleaner. Once you break it loose all the way around it is easy to remove.

Air Cleaner

Thank you for the information but how does one gain access to the filter? My old coach access was thru a rear baggage door. I have seen a video of another model coach a Forest River push and the guy had to remove the bed with the frame just to get access to the filter! Will never buy that coach. Hopefully, Newmar gave consideration to servicing the coach.

On mine it is under coach on drivers side outboard from engine with plenty of room to work. I raised it with leveling jacks with HD jack stands for safety. It took about 20 minutes.

Lots of room to work and its not all that difficult.
Be sure to be meticulous with cleanliness as anything on the downside of the filter will end up in the engine.
If dirty on outside of connections clean them up before disconnecting. Wipe all accessible inside surfaces down to make sure no dust or dirt present.

Just out of curiosity Robert, how many miles on the coach? Iím at 22k and close to replacing, but the suck-o-meter says itís fine. I just want a fresh one in there. Is that where youíre at or do you put on a lot of miles?

x2 on that and use a shop vac to clean all loose dust out of the housing, then wipe it down - the old saying was, “A teaspoon of dirt can cripple a diesel”, so as Winemaker says, be meticulous.

My coach has 16,000 miles the meter shows the filter is still good. I just do not trust the meter. My last coach had the same meter and showed still good. Removed the filter and it was full of dirt.

My last trip last winter I was on several roads that has lots of sand on them in Texas.

Agree its not only gauge reading.
Mine was used when we bought it and was original. Only 20,000+ miles but about 5 yrs so wanted to be sure. Looked good and no evidence ow any moisture.
Now I know and comfortable...sleep well
