I’d released the counter springs on the hinges decades ago and so the hood would no longer hold itself up; not without a prop rod. The springs were tensioned to their weakest setting and I knew not how to increase it. Tools on hand at the time were a pair of vice grips with bailing wire; good enough to release a spring but clumsy. Coil springs have stored energy and can cause injury when mishandled. Uncertain about how to [properly] go about it and a bit apprehensive the job was put off. Fast Forward today to the Internet Age; a Youtube hit gave inspiration.
If the springs could be extended and placed in the hinge’s more extreme setting slot then the increased force under tension would correctly balance the open hood. Unfortunately, the size of each individual spring (one per hinge) was such that mere muscle power would not overcome the difficult flexing required to get that job done. Leverage was needed.
A couple of Ratchet Tie-Down Trailer Straps provided the persuasion. An concrete post in the garage floor lent an immovable anchor point. A second strap maintained a proper pull angle since the post was off center.
The ratchet acting as a winch provided the grunt and the ear of the spring was positioned adjacent to its proper location. With care and finesse the spring could then be hooked over the tang and into the correct slot on the hinge mount.
I have to give thumbs-up acknowledgement to the Youtuber DIY; he sure made it look easy. Well, it’s never easy but a least now finally — no more prop rod! A bucket list project perceived as insurmountable all these years gets resolved.
