How to Service and Repair a Radiator Cap on 2001 Jeep Wrangler?

To service the radiator cap, clean it with mild soap and water. Inspect it at eye level; if the vent valve doesn't open due to a swollen gasket, replace the cap. Ensure any replacement cap is designed for a coolant reserve system and has a sealed diaphragm spring and rubber gasket.
