1. Preparation:
* Coolant: Ensure the engine is completely cool before attempting this. Hot coolant will cause severe burns.
* Tools: You'll likely need a pair of pliers (needle-nose are often helpful), possibly a small flathead screwdriver to pry gently, and some rags or shop towels to absorb spilled coolant.
* Container: Have a container ready to catch the coolant that will drain from the hoses.
2. Locating the Connector:
* Identify the specific heater hose connector you need to remove. Consult a repair manual or online diagrams for your Windstar's year and engine to be sure. The heater hoses are usually near the firewall, and the connectors might be on the engine or near the heater core.
3. Hose Clamp Removal (if applicable):
* Many heater hoses use spring clamps or worm-gear clamps. Loosen the clamp using the appropriate tool (often pliers). Some clamps can be squeezed to loosen, while others require turning. You may need to rotate the clamp to release its grip. Once loosened, gently slide the clamp away from the hose and connector.
4. Connector Separation:
* Push-on connectors: These are the most common. They typically require squeezing the connector's tabs (often located on the sides) while gently pulling the hose. Sometimes a small flathead screwdriver can assist in prying open the tabs, but be extremely careful not to damage the connector's plastic.
* Other types of connectors: Less common types might involve threaded connections or other fastening methods. If you encounter something unusual, a repair manual will be invaluable.
5. Hose Removal:
* Once the clamp is loosened (if any) and the connector tabs are released (if a push-on type), gently pull the hose off the connector. There might be some resistance due to the hose's stiffness or build-up of deposits inside.
Important Considerations:
* Fragile plastic: Heater hose connectors are often made of plastic and can easily break. Use gentle, even pressure when separating the hose. Avoid excessive force.
* Coolant: Be prepared for some coolant spillage. Have your container ready.
* Repair manual: A repair manual specific to your 1999 Ford Windstar is highly recommended. It will have diagrams and detailed instructions, making the process much safer and easier.
If you're uncomfortable performing this task, it's best to take your Windstar to a qualified mechanic. Working with automotive coolant requires caution, and improper handling can lead to damage or injury.
