AC delete - how to fill front condensor blower intake / exhaust openings

[grahamkissack]

I just finally completed an AC delete on my SC. Those hoses hold lots of dirt...anyone want 10 lbs of Texas back?

Anyway, interested in seeing pictures in how folks have filled the condensor blower openings. The discharge looks obvious but what about the curved upper section (second pic)....see pics below??

Thanks, Graham

For the blower hole, I took a rectangle of 1/8" thick pressboard, painted it black, and used black silicone adhesive to cement it in place.

The hole in the bulkhead wasn't a problem as I replaced the entire bulkhead as part of my backdate project, but I would have treated it the same way. Pieces of sheet metal would work too.

When you pull the gasket for the intake you will notice that the hole is askewed, its not flat. You can take some 18 gauge and bend it to fit, use self taping screws and stone guard the whole thing. I got lazy and used duct tape covered with a layer of black caulk, I caulked around the joint as well. In effect I made a plug.

My car isn't driven much and is parked inside. I also plan to pull the bumper again this winter and will use thin gauge metal tacked in place. I wanted it to be reversible.

I used .062" ABS plastic sheet. Heat gun to form irregular surface. Then bead of silicone and Alluminum rivots. I attached from the outside, bottom and front. You don't want water getting in.

Just did this - There are a couple of ways to do this - basically you want to cover the hole, effectively so no debris, water etc can get in there.

1 You can get some thin sheet metal, form and then tack it in with a MIG, then use seam sealer (Wurth works great and is super strong and paintable in like an hour)

That is what I did for the bigger pieces - looks factory - can't tell a hole was there.

2.) You can get some aluminum tape (same stuff used to seal up walk in freezers) - put a few layers over the holes and then seem seal - still very strong and much easier to deal with, paint etc.

3.) Rubber tape used to seal up flashing for roofs etc - then you guessed it - seam sealer, paint etc.

Lots of options - wouldn't say any of the above or right or wrong. For me for the external holes I used metal and tacked with the mig. For the internal in the trunk I used the freezer tape then seam sealer - virtually the same as the sheet metal when all dried and painted - easier and looks factory.

Hope this helps -

For the first hole, I took some thin aluminum from Home Depot, snipped it to fit and am in the process of using a drill press to put some holes into, then use a bit of weather stripping around the edges of it so I can use the four bolts that held the auxiliary fan in place to hold the aluminum panel.

The second hole for the intake to the aux fan, I'm probably just going to form aluminum into place. I intend to install a center mount cooler and at that point, I'll install the RSR style ducting into the front of the tub.

Exactly how I did mine. I wanted the block-off to be reversible in the event that a future owner of my car might want to restore the A/C system.
