Note: Before starting any work on the vehicle, make sure the engine is cool to the touch to prevent burns. Additionally, please follow any safety instructions or precautions that come with the specific antifreeze you purchased.
Materials Needed:
- New Antifreeze (Check your owner's manual for the recommended type and amount)
- Funnel
- Coolant/Antifreeze Tester (Optional, but recommended)
- Safety Gloves and Goggles
- Clean Rag or Towel
- Wrench or Pliers (if necessary)
Step-by-Step Instructions:
1. Locate the Cooling System Drain Plug:
- The cooling system drain plug is typically located on the lower side of the radiator. In newer vehicles like your 1995 Crown Vic, it might not have a traditional cap, but a drain plug instead.
2. Prepare the Vehicle:
- Make sure the engine is cool and the vehicle is parked on a level surface.
3. Wear Protective Gear:
- Put on safety gloves and goggles to protect yourself from potential spills and splashes.
4. Open the Reservoir Cap:
- Open the coolant reservoir cap to relieve any pressure in the cooling system.
5. Locate the Drain Plug:
- Find the drain plug on the radiator by looking for a small, usually 13mm or 16mm, bolt at the lowest point on the radiator.
6. Place a Container Underneath:
- Position a drain pan or container underneath the drain plug to catch the antifreeze as it drains.
7. Open the Drain Plug:
- Using a wrench or pliers, turn the drain plug counterclockwise to loosen and remove it. Be cautious as antifreeze may spurt out. Allow all the old coolant to drain into the container.
8. Close the Drain Plug:
- Once the coolant has drained completely, replace and tighten the drain plug firmly.
9. Add New Antifreeze:
- Consult your vehicle's owner's manual for the recommended antifreeze type and quantity for your Crown Victoria.
10. Use a Funnel:
- Use a funnel to add the new antifreeze to the coolant reservoir. Add it gradually, checking the level in the reservoir as you go.
11. Fill According to Level Markings:
- Fill the reservoir until it reaches the indicated "FULL" or "MAX" level marking.
12. Test Antifreeze Mixture (Optional):
- To ensure the right mixture, use a coolant/antifreeze tester to check the concentration level of antifreeze in the system. Adjust as needed.
13. Close the Reservoir Cap:
- Replace the coolant reservoir cap securely to prevent leaks.
14. Run the Engine:
- Start the engine for a few minutes to allow the antifreeze to circulate.
15. Recheck Levels:
- Let the engine cool down and recheck the antifreeze level in the coolant reservoir. If needed, add more coolant to bring it back to the "FULL" marking.
16. Clean Up:
- Clean up any spills using a rag or towel.
17. Dispose of Old Antifreeze Properly:
- Collect and dispose of the drained antifreeze responsibly, following local environmental guidelines.
18. Monitor Coolant Level:
- Keep an eye on the coolant level in the reservoir over the next few days to ensure there are no leaks.
Remember, if you're not confident performing this task, it's always a good idea to consult a qualified mechanic for assistance.
