Jeep Wrangler: Cooling System / Coolant Checks
Check the engine, battery (if equipped), intercooler (if equipped), and Motor Generator Unit (MGU) (if equipped) coolant (antifreeze) protection every 12 months (before the onset of freezing weather, where applicable). If the engine, battery (if equipped), intercooler (if equipped), and MGU (if equipped) coolant is dirty or rusty in appearance, the system should be drained, flushed and refilled with fresh OAT coolant (conforming to MS.90032) by an authorized dealer. Check the front of the A/C condenser (if equipped) or radiator for any accumulation of bugs, leaves, etc. If dirty, clean by gently spraying water from a garden hose vertically down the face of the A/C condenser (if equipped) or the back of the radiator core.
Check the engine, battery (if equipped), intercooler (if equipped), and MGU (if equipped) cooling system hoses for brittle rubber, cracking, tears, cuts, and tightness of the connection at the coolant recovery bottle and radiator. Inspect the entire system for leaks. DO NOT REMOVE THE COOLANT PRESSURE CAP WHEN THE COOLING SYSTEM IS HOT.

Use this simple 5-step test to decide whether the child can use the vehicle’s seat belt alone: Can the child sit all the way back against the back of the vehicle seat? Do the child’s knees bend comfortably over the front of the vehicle seat – while the child is still sitting all the way back? Does the shoulder belt cross the child’s shoulder between the neck and arm? Is the lap part of the belt as low as possible, touching the child’s thighs and not the stomach? Can the child stay seated like this for the whole trip? If the answer to any of these questions was “no”, then the child still needs to use a booster seat in this vehicle...
