What This Covers

In this guide, we’ll walk through the steps needed to replace your Jeep’s coolant overflow bottle, including necessary tools, the removal process, and tips for ensuring a successful installation.

Step-by-Step Breakdown

1. Gather Your Tools: You'll need a flathead screwdriver and a new coolant bottle. For the 2015 Jeep Wrangler, the Crown Automotive Coolant Bottle is a great choice, providing a direct fit and solid performance.
2. Locate the Old Coolant Bottle: Start by opening the hood and locating the coolant reservoir. Look for signs of leakage, which may include coolant drips under the vehicle.
3. Remove the Old Bottle: Use the flathead screwdriver to unscrew the fasteners that hold the coolant bottle in place. These are often plastic rib nuts similar to those on the front grille. Once unscrewed, gently pull the container upwards to remove it.
4. Inspect for Damage: Check the old bottle for cracks or holes. In case of leaks, it's always wise to check nearby hoses and connections as well to ensure there are no additional issues.
5. Install the New Reservoir: Position the new Crown Automotive Coolant Bottle where the old one was. Make sure it is seated properly, then secure it with the fasteners you previously removed.
6. Transfer the Cap: If the cap from the old bottle is in better condition, you can transfer it to the new bottle for continued use.
7. Add Coolant: Once the new bottle is secure, refill it with the appropriate coolant as per your vehicle’s needs.

Helpful Tips

• Always allow the engine to cool down before working on the cooling system to avoid burns from hot fluid.
• Dispose of the old coolant properly, as it can be harmful to the environment.
• Check the new bottle regularly after installation to ensure no leaks reappear.
