Where is the oil cap on a 98 gmc jimmy?

On a 1998 GMC Jimmy, the oil cap is located on the engine's valve cover, typically at the top of the engine. It is usually marked with the Word "Oil" or an oil can symbol. To access it, simply look for a round cap that can be twisted off, allowing you to add oil as needed. Ensure the engine is off and cool before attempting to remove the cap.
