Windshield Fluid Reservoir Seal
So a few days ago I noticed some rust around the edge of my windshield fluid reservoir, caused by fluid sloshing out of the reservoir. After popping the cap I noticed the seal had shifted and appeared to have shrunk as well.
I tried finding a replacement cap online, but none come with a seal that I could find. So I removed the seal, cleaned up the cap and cut some thin closed cell foam to make a new seal. This seems to be working well and at the very least better than what it was before.
Thought I’d share this in case anyone else has looked for a cap with a seal – without any luck finding one.

The closed cell foam helped out a lot.
I decided to see if I could force any to fluid to slosh out by zigzagging down an empty country road. After inspecting I noticed a small trace of windshield fluid near the same spot it had rusted up before. So I decided to make a baffle to put inside the windshield fluid reservoir as well. I went to my local hardware store and bought a plastic gutter guard, cut it to fit and stuffed it in. I then used a screwdriver to move it up and across the top of the opening. This solved the issue completely and it’s dry as a bone, and no more wiper fluid is escaping and puddling on the inner fender well.
