List the part numbers of the belts.
List the part numbers of the pulleys. Take a couple pics of either side of the pulleys on the engine. We are flying blind trying to help because you are not providing enough info to diagnose. .

Multiple sources for the same product. Sometimes with different-color molded plastic parts (Yellow, blue, black, "morning sickness green", perhaps others.) Example: KR1 for V-belts ![]() I got mine from NAPA about thirty years ago. KR1 = V-belts <50 to 150 pounds tension. https://www.napaonline.com/en/p/NBHKR1 KR2 = Serpentine/multi-rib belts. 100--300 pounds tension. https://www.napaonline.com/en/p/NBHKR2 For the record, NAPA's pricing is insane. Amazon has 'em for about half of what NAPA wants. Continental (Goodyear) has a third version, for belts that require 300--700 pounds of tension. Not something I deal with. http://www.amazon.com/Continental-El...WPW/ref=sr_1_8 Quote:
Top--Bottom of the driven pulley Left--Right of the driven pulley Forward/Rearward compared to the drive (usually the crankshaft) pulley. All measurements are in relation to the crankshaft pulley. The tolerance I use is 1/8 inch for nearly all automotive applications. Last edited by Schurkey; 03-07-2026 at 07:53 PM. |

Yeah I wasn't too concerned about pulley alignment when requesting pics, was more so wanting an overall view to see if there were any glaring issues/concerns.
Like, we could get a bird's eye view of the belts, determine series, fan and accessory setup, etc. .
