How to Maintain the Coolant in Your Jeep Wrangler

Model: Jeep Wrangler MK 3, JK - Years 2007-2018
Part: Antifreeze coolant

To maintain your Wrangler, start by checking the coolant level in the engine cooling system. Remove the rubber hooks at the sides of the bonnet. Lift the front bonnet and secure it. Remove the cap from the coolant reservoir and check the level by looking at the indicator. If the coolant is low, top it up to the indicated level. Close the bonnet and reattach the rubber hooks.
