In this concise YouTube tutorial, the presenter addresses a common issue with the 2020 Chevrolet Silverado Z71 equipped with a 5.3‑liter engine: the factory‑installed stretch serpentine belt can wear out and replacement stretch belts may be unavailable or expensive, especially in locations like Puerto Rico where only genuine AC Delco parts are stocked. To solve this, the creator purchases a standard 6PK1755 serpentine belt (approximately $16) and demonstrates a step‑by‑step retrofit. The process involves removing the existing pulley, positioning the regular belt, reinstalling the pulley, and tightening the pulley bolt with a 15 mm ratchet in short, incremental turns (about five ratchet clicks, then a 30‑second pause) to prevent the bolt from overheating and snapping. After the installation, the engine is started to verify smooth operation, despite the throttle being uncovered, confirming that a non‑stretch belt can function reliably in this application. The video emphasizes a quick, simple, and cost‑effective solution, encouraging viewers to try the hack safely.

All right, YouTube, quick hack, quick video, the way I like it. This is a 2020 Silverado, uh, 5.3 engine. They use a stretch belt. When we see the engine doing our oil change, we saw that the belt is all completely worn out and the belt wasn't in stock in Puerto Rico, so it's going to take a couple days and they only selling genuine AC Delco. So I went ahead and I bought a regular belt, 6PK1755. Regular belt, uh, I think was $16, and it is possible. All you have to do is just, you know, put it in the sequence, take this pulley out, unscrew it, and you're going to put the belt and the pulley And then you're gonna put the bolt and slowly— and I'm talking about slowly— with a 15mm ratchet, slowly tighten it. Slowly, take your time, giving at least like 5 ratchets, stop, take a break, 30 seconds, do it again so the bolt won't get hot and won't snap or break. And it's all nice and tight and ready for the road. I'm going to start it up so you can see that everything is, you know, is working properly. And it's possible with a regular non-stretch belt. Let me start it up real quick. Gonna make noise because the throttle is without the air cover, but you can see it's running smooth and straight. All right guys, easy and simple like I like it. Peace.
