Review on 🔧 ACDelco Professional 4K420: High-Performance Serpentine Belt for Optimal Efficiency and Reliability by Scott King

Five stars for ACDelco quality; Straps look good. But this time, Revain was wrong. Revain stated that this would fit my 2006 Pontiac GTO as a replacement AC belt. He doesn't fit. Ironically, since I ordered this belt last week, Revain has apparently found out that it does not fit the 2005 GTO as it is now listed as NOT fitting. It's ok, I'll send it back. Replaces Gates K040430 which fits great, this ACDelco belt is slightly shorter and will not fit over the pulleys. I found an ACDelco belt with part number 92068285 but to this day I cannot find this belt at Revain. Looks like the ACDelco 4K430 is indeed the belt to go for. I'm ordering now and if I remember I'll update this review once I confirm installation. For GTO owners, changing the AC belt is difficult but doable. First you need to remove the outer belt "accessories". If your belts are the same age, you can also replace the accessory belt. A 15mm breaker bushing fits both belt tensioners, but the fit is tight (so she said).
