Tools You'll Need:
* Drain pan: Large enough to hold several quarts of coolant.
* Wrench: The size will depend on your specific vehicle, but it's likely a 1/2-inch or 9/16-inch wrench. Check the petcock and drain plug to determine the correct size.
* Gloves: Coolant is corrosive.
* Safety glasses: Protect your eyes from splashes.
* Funnel (optional): To help refill the radiator.
Procedure:
1. Locate the Radiator Drain Petcock: This is usually a valve located at the bottom of the radiator, on the driver's side. It's often a small, threaded plug or a valve with a lever.
2. Locate the Engine Block Drain Plug: There may also be a drain plug located on the engine block itself. This is typically lower than the radiator drain. This one is optional, but it will help drain more of the old coolant. You'll need to consult your repair manual or a diagram to locate this accurately.
3. Position Drain Pan: Place the drain pan under the radiator drain petcock (and the engine block drain if you are using it).
4. Open the Radiator Drain Petcock: Carefully turn the petcock counterclockwise to open it. If it's a valve, carefully open the lever. The coolant will begin to flow.
5. Open the Engine Block Drain Plug (if applicable): If you've located the engine block drain plug, carefully open it now, letting the coolant drain into the pan.
6. Let it Drain: Allow the coolant to drain completely. This may take some time.
7. Close the Drains: Once the coolant has stopped draining, close the radiator drain petcock (and engine block drain plug if applicable) by tightening them securely.
8. Dispose of Coolant Properly: Coolant is toxic and should be disposed of properly. Many auto parts stores and recycling centers accept used antifreeze. Check your local regulations for proper disposal methods.
Important Considerations:
* Consult a Repair Manual: A repair manual specific to your 1995 Dodge Intrepid will provide precise locations for the drain petcocks and plugs, along with torque specifications for tightening them. This is highly recommended for accuracy and safety.
* Coolant Type: When refilling, use the correct type and mixture of coolant recommended for your vehicle. This information is usually found in your owner's manual or on a sticker under the hood.
* Air Bubbles: After refilling, run the engine for a few minutes to circulate the coolant and bleed out any air bubbles that may have formed. Check the coolant level and top it off as needed.
* Pressure Testing (Recommended): After draining and refilling, consider a pressure test. This will show you if there are any leaks in your cooling system.
If you are not comfortable performing this task yourself, it's best to take your vehicle to a qualified mechanic. Working with coolant involves potential hazards, and a mechanic has the expertise and tools to do the job safely and correctly.
