Any recommended universal coolant reservoir tanks? (Page 4/4)

That is exactly what the genesis of this thread was... the plastic on one corner of my original coolant reservoir broke down due to UV rays coming through one of my hood vents. Here's the hood...



And here's what ten years worth of UV rays have done to the corner of the reservoir that was exposed...



I fabricated an aluminum sheet metal cover for my replacement reservoir today, so as to prevent it from suffering the same fate. I'll post a photo when installed.

Ugly...

But the Bolt Hole breaks just for load on small upper section.
GM used a captive washer nut but doesn't help much.

Better is sandwich the "ear" w/ light sheet metal that folded under the ear so a lot more plastic is supported.

Bottom bolt hole breaks too often because upper already broke and GM and others over torqued the hardware.

Just for clarification... I wasn't suggesting that UV rays had anything to do with the broken plastic mounting tab. It was already broken when I got the Formula, which of course at the time had the factory hood with no vents.

I fabricated my reservoir cover using my '84 as a template... and then I realized that it wasn't going to fit the Formula (without further modification) because the Formula has a rad fan shroud (was originally an A/C car) whereas the '84 has a regular rad fan mount. Had to change things up a bit as I designed the reservoir cover to attach to the top right rad fan mounting bolt. Not a big deal, but I'm as slow as cold molasses.

Okay, reservoir shield installed. The orange colored arrow is pointing to the area where the previous reservoir was destroyed by UV rays coming through one of my hood vents. The red arrows are pointing to where the shield is attached.



Not bad re-use of a 10" length of old aluminum gutter.
