Where can I find a vacuum hose diagram for a 2000 GMC Jimmy? I have a vacuum hose off and I’m not sure where it connects at. I think it might go to the overdrive or the one to one lock up, but I need a picture or a diagram to hook it back up. My Jimmy idles rough and hesitates.
Answer: Open your hood and look on the top of your radiator or on the underside of the hood. Look for a 3 inch by 3 inch white sticker. All cars/trucks made since the ’80s have a vacuum hose diagram, timing specification, and engine model/emisions standard stickers somewhere in the engine compartment.
