Wausau 911

I have a compressor and saw a post relating that a dealer did this for a member. Assuming this can be a DIY, how can I perform this seeming easy task? Thx for replies.

I did this myself the other night. Biggest pain is dealing with those stupid plastic pop rivets in the wheel wells. I had the car on jack stands already because I was working on something else. I think that made it easier to get to all of the screws along the bottom. Photos here:

Be careful blowing the debris out. The fins are fragile. I think the only way to clean them is the way GeorgeCo and Hurdi posted. I use the soft brush on my vacuum and then run the hose with the nozzle set on "rain" after I get access. YMMV

Holy crap GeorgeCo, there is a lot of crap in there! I definitely have to clean it out this year.....

Yeah, i definitely wouldn't use high pressure air. I used a hose and a soft bristle brush to not damages the fins.
i also have some extra push pins for when i damage them.

Maybe a shop- vac would be more controllable.

The techs do this for me when I take my cars in.

I mention it to the SM so he adds this to the work order as a reminder to the techs though I suspect they do not need any reminding.

There are a couple of points: One is the blowing out will not remove a heavy build up of crud. I had the bumper covers of both cars removed and these areas thoroughly cleaned.

Two: I drive my cars a lot -- easily between 10K and 20K miles per year -- so they are in for service (at least oil/filter services done every 5K miles) several times a year. Because of the frequent servicing the trash gets removed before it requires the bumper cover be removed.

The tech uses an air nozzle to blow from behind/underneath the car through holes/gaps in the underbody panels so the stuff gets blown out the front of the car the way it came in.

I have watched the techs do this more than once and I see no risk to the car, the radiator, the condenser or the other hardware in that area.

I clean them annually:

At the beginning of the upcoming season, I'll install screens to reduce debris intake.

Cleaned mine out a few days ago. I think it needed it.

+1. Easy do it yourself job that should be done annually. I use a shop vac and hose to wash all the debris out from between the fins.
