Washer fluid reservoir cracked
 

So I got a decent sized crack in my washer fluid reservoir (don't ask how), and instead of replacing it, I thought I would just re-seal it. I used JB ClearWeld to do it. I let it sit for a full day, and put it back together. It was fine for a day or so, then the light came back on. The epoxy had gone soft and appears to have been eaten by the washer fluid. I'm assuming it's from whatever additive it is that is used to keep the fluid from freezing.

Any suggestions on what I can use that is chemical resistant?

try soldering iron and melt and reseal?

The light came on? For the windshield washer bottle? Replace it, they are cheap.

There's a light for that?

Well, if you want to reseal it your only real hope is to remove the epoxy, cut it a little wider, and weld it together using a soldering iron and an hdpe or ldpe filler material/scrap.

If not, I have a one of the translucent ones without a motor that I can sell you.

Yeah there is some confusion going on here.

Apparently it is a thing on at least some non-US spec rx8s.

Hmm, the more you know...

Yeah they have it because of the headlight washers, that makes sense.

what I ended up doing is cutting a small square "patch" out of an old washer fluid container and melting it onto the crack. Worked like a charm.

I found that when I topped off my reservoir (as shown) I would see some washer fluid appear on top of the washer fluid reservoir. There is a seam leak on both sides as indicated. I've always used 0 °F summer and -25 °F winter blends in the washer fluid tank. I bet heat and seam quality are to blame on my Series ][.
