1. Safety First: Let the engine cool completely before attempting this. Hot coolant can cause serious burns. Wear safety glasses and gloves.
2. Locate the Drain Cock/Petcock (on the radiator): Many radiators have a petcock (small valve) at the bottom. It's usually a plastic or brass plug. This is your primary drain point for the radiator itself. However, it's crucial to understand that many Dakotas, particularly from that year, might not have a petcock on the radiator. Instead, you'll rely on step 3.
3. Locate the Engine Block Drain Plug: This is a more reliable method to ensure complete draining. Consult your owner's manual or a repair manual specific to your 2002 Dakota for the exact location. It's usually located on the engine block, low down and near the bottom of the radiator hose connection. It's typically a bolt or plug.
4. Position a Drain Pan: Place a large drain pan under the radiator (if using the petcock) and/or under the engine block drain plug. Make sure the pan is large enough to accommodate all the coolant.
5. Open the Drain: If your radiator has a petcock, carefully loosen and remove it. If not, carefully loosen and remove the engine block drain plug. The coolant will start to flow.
6. Open the Radiator Cap: Once the coolant is flowing from the drain, open the radiator cap carefully. This will allow for faster and more complete draining. Again, be cautious of hot coolant.
7. Wait for Complete Draining: Allow sufficient time for all the coolant to drain.
8. Close the Drains: Once drained, replace the petcock or engine block drain plug, tightening it securely.
9. Refill: Once drained, refer to your owner's manual for the correct type and amount of coolant to refill the system. Use a 50/50 mix of coolant and distilled water (unless otherwise specified).
Important Considerations:
* Owner's Manual: Always consult your owner's manual for specific instructions and diagrams.
* Repair Manual: A repair manual specific to your vehicle will provide detailed diagrams and instructions.
* If Unsure: If you're uncomfortable performing this task yourself, take your vehicle to a qualified mechanic. Incorrect draining can lead to further problems.
This process ensures you drain coolant from both the radiator and engine block, giving you the most complete drain. Remember safety first!
