Default $6 radiator diversion plate

Im 19 with tuition bills, so I can't really afford to fork over $60 for a steel plate. I try to save money where I can so I decided to give making my own radiator diversion plate a go.

I found this $6 36" piece of ducting at home depot.

I went home and made a rough template out of cardboard of a basic shape of the diversion plate.

Im not an HVAC guy so i don't really know the best way to cut sheet metal, so i just sat around with some tin snips and carefully cut out the basic outline.

After trial and error and a lot of measuring, I eventually had the plate cut out. I used a rattail file and sandpaper to clean up the edges. I don't remember the drill bit size but I drilled holes in the OEM location where the bumper clips snap into the rad support. I used these to hold the plate in place.


ALSO, idk how forums work lol so hopefully I'm doing this right...

Nice! I felt stupid after buying one for $70 and realizing just how simple it is. In fact mine didn't fit great so I had to trim with a Dremel.

FYI what front bumper is that?

We need more posts like this. DIY-er's making things from "scratch" being cheap/functional.

This is actually a really nice job from the photos, I wouldn't have the patience to do that.(anymore)

I paid $200 for a greddy CF one. Luckily it was cracked when it arrived. Biggest ripoff ever. The thing was as thin as cardstock........traced it and sent it back.

Nice job. Not sure if you did it or not, but you can clean up the inside corners better if you drill first before cutting.
