FYI, it is a 2000 Civic EX with D16y8 head and D16y5 block.

I got tired of manually tensioning the alternator belt alone, so I made this thinger from scraps and an eye-bolt from Tractor Supply. As you can see, I bench-tested the strength and then added some angled aluminum to reinforce the steel bracket.

Used:
- eye-bolt for 150lbs.
- fiber reinforced fuel line.
- silicon tubing for mounting eye-bolt to alternator.
- metric 10mmx1.5 bolt for mounting eye-bolt to alternator.
- extra washers.
- used copper crush washers around fuel line to brace bracket.
- zinc-dipped grade nut for eye-bolt.
- grade 10 nylon lock-nut.
- angle aluminum.
- Mobile1 synthetic grease for the tube and fuel line.

Remember, this tensioner is only used to enable the initial tension. Then tighten the mounting bolts to hold the tension. This device isn't really intended to support the belt tension long-term.
