Just got me a new k&n filter for my hhr and I can't figure out how to get the filter housing off so i can replace stock filter with my new k&n filter?

Does anyone know how to do this on a stock hhr?

Any help would be appreciated.

Sincerely,

The search feature is your friend. I typed in air filter remove and got this information off a post by Mike from SoCalHHR's.

From the Owner's Manual:

To inspect or replace the filter, do the following:

1. Disconnect the MAF sensor, PCV hose, and both ducts.

2. Pull the entire system from the top of the engine.

3. Flip the system over and place it on a soft, non-abrasive surface.

4. Remove the screws that hold the housing and cover together and lift off the housing.

5. Inspect or replace the engine air cleaner/filter.

6. Reverse the steps to reinstall the system. Be sure to reinstall the housing tightly.

thanks courthousedeb,

I disconnected the MAF sensor, Then i unhooked the pvc hose and both ducts. But I still could'nt get that filter housing off, I don't know if something else is keeping it from coming lose or what. I did not want to pull to hard because I thought i might break something. I done a search on the internet but its to new of a model and there is nothing posted about it yet.

once you have the hoses disconnected, just pull up hard...you won't break anything

On the 2.4 --- Well there are 2 nuts on the bracket that runs from the bottom of the air box to the exhaust manifold.....then just pull up to remove the air box from the gromet/stud on the top of the head...left-front side looking down......Then you get to back out all eight of those screw to uncover the filter......They (GM) must of thought it was going somewhere

They (GM) must of thought it was going somewhere

Well, all the fuses were coming loose so bad....

:D

I love the way the automakers seem to go out of their way to make the simplest job a real hassle. Sometimes I think they do it just to force some of the owners who are a little less handy with tools, to take their vehicles back to the dealer for every little thing. And then get charged an arm and a leg for doing it.

Yes, for the past 20 years they have designed that crap into their auto's....the dealers get the high labor charge and the Manufactures sell more OEM parts....it's a win - win - you lose concept!!!

THANKS EVERYONE FOR THE REPLYS...

Finely got that big filter housing off and got my k&n filter installed. I will post results here in a day or two.

Thanks Again,

I've had a new K&N filter sitting here waiting, for my next oil change, to install.
I'm not looking forward since reading about your troubles. But, Guess I'll take a crack at it! We'll have 6000 miles on the HHR then, so I'm also going to start using the "Lube-It" (From Fluoramics) additive at that time.

I have been putting k&n filters on my cars and trucks for about 20 years now, They will work just fine as long as you don't over oil them. If you over oil it, Then it will cause alot of problems. K&N says they need to be cleaned every 50,000 to 100,000 miles, If you need to clean the k&n filter or recharge it just make sure to not over oil the filter.

At the motorcycle shop I worked at we found out a dirty K&N filter has a better pull than a brand new one :wtf:

:cool: That's kinda what K&N says in their own literature! Sounds strange but it may true :confused: . There must be a point where that isn't the case though. I've used their air filters on my last 4 or 5 vehicles and never had any problems. I usually clean them at about 25,000 Mi. just to play it safe. Even that may be too often?? :bye:

Just a "heads up" for those taking the a/f housing off.... Be very careful pulling it off!! The grommets can tear!!

A couple of months ago I had my HHR at the dealer for the A/C noise fix (hoses replaced) and when I got home to take a look, the a/f was not tight. Upon closer inspection I found one of the rear and the front grommet were torn.

Called the dealer and they said they'd order new grommets. Good ol' GM, however, does not sell the grommets seperately!! The dealer grumbled that they had to order both halves of the filter box. We both thought that was a bunch of crap. I suggested to the Svc. Mgr. that he make it a warranty claim and put the bill on GM's lap.
