The Jeep Wrangler engine uses a serpentine belt to turn the components around the front of the engine. The belt is constructed of nylon-reinforced rubber and runs more than the alternator, power-steering pump, water-pump and air-conditioning compressor. It’s critically crucial that the belt follow the correct path above the pulleys or the belt may possibly spin the add-ons the wrong direction. The Jeep Wrangler features a sticker under the hood with the belt path printed on it that you simply can refer to if you are unsure of the belt path.
1. Open the hood of your Jeep Wrangler. Find the battery cables where they attach for the battery terminals. Locate the bad cable; it’s usually black and features a large “-” symbol embossed inside the battery case next to it. Remove the negative cable from the battery following loosening the retaining bolt having a wrench.
2. Discover the serpentine-belt tensioner about the front from the engine. It’s a metal arm using a tiny black plastic or metal pulley on it. The arm has a square hole in it. The tensioner is located below the alternator about the Wrangler.
3. Insert the square drive from a 3/8-inch drive ratchet or breaker bar into the square hole about the tensioner arm. Rotate the ratchet or breaker bar counterclockwise to release the tension around the serpentine belt. Remove the belt from the engine pulleys and carefully rotate the tensioner back to its home position.
4. Install the new belt onto the engine pulleys, utilizing the belt-routing diagram below the hood as a guide. If the belt is not around the pulleys correctly, damage to the components and engine will occur. Leave the belt off the tensioner pulley for now.
5. Rotate the tensioner counterclockwise using a ratchet or breaker bar then slide the belt onto the tensioner pulley. Rotate the tensioner clockwise, allowing the tensioner to remove the slack from the belt. Remove the ratchet or breaker bar in the tensioner arm and out with the engine compartment.
6. Connect the damaging battery cable towards the battery, then tighten the retaining bolt until it’s snug. A wrench or socket and ratchet will work, so use whichever you choose. Close the hood of one’s Jeep.
