When you have routine maintenance done on your Dodge Caravan, the shop usually checks vital fluids such as antifreeze. However, if you are a do-it-yourself mechanic your Caravan rarely sees a repair garage. This means the responsibility of topping off the coolant falls to you. Fortunately, the process for adding coolant to your Dodge Caravan is simple and is a basic part of the maintenance process.
Step 1: Open the engine hood and prop it with the hood prop.
Step 2: Remove the radiator cap from the filler tube.
Step 3: Place a funnel into the filler tube.
Step 4: Fill a 50/50 mixture of antifreeze and distilled water into the radiator until the fluid level reaches the top of the filler tube. Remove the funnel.
