It's usually a small valve or a plastic plug. You'll likely need:
* A shallow pan or container: To catch the coolant. Radiators hold a significant amount, so make sure your container is large enough.
* A wrench (possibly): Some drain valves are simple and can be turned by hand, but others may require a small wrench (usually a crescent wrench or adjustable wrench will work). Check before starting.
* Gloves: Coolant is corrosive and can irritate your skin.
* Eye protection: Always a good idea when working with fluids.
To open the drain:
1. Locate the drain: Look closely at the bottom of the radiator on the driver's side. It might be a small, threaded plug or a valve with a handle.
2. Place your drain pan: Position the pan underneath the drain valve.
3. Open the valve/remove the plug: Carefully turn the valve counter-clockwise (if it's a valve) or unscrew the plug (if it's a plug). Do this slowly to avoid a sudden gush of coolant.
4. Let the coolant drain: Allow the coolant to drain completely. This may take some time.
5. Close the valve/replace the plug: Once drained, carefully tighten the valve or replace the plug securely.
Important Considerations:
* Engine Temperature: Always let the engine cool completely before draining the radiator. Hot coolant can cause serious burns.
* Coolant Type: Note the type of coolant you drain so you can replace it with the correct type. Check your owner's manual for specifications.
* Disposal: Dispose of the old coolant properly. Most auto parts stores will accept used coolant for recycling. Never pour it down the drain or on the ground.
If you can't locate the drain valve, consult your Jeep Grand Cherokee's owner's manual for a diagram or further guidance. If you are uncomfortable performing this task, it's best to take your vehicle to a qualified mechanic.
