Before You Begin:
* Safety First: Disconnect the negative battery terminal to prevent electrical shorts.
* Gather Tools: You'll likely need a variety of tools including screwdrivers (Phillips and flathead), possibly sockets and wrenches (sizes will vary), pliers, and possibly a trim removal tool to avoid scratching plastic.
* New Pump: Make sure you have the correct replacement pump for your vehicle.
General Steps (Consult your repair manual for specifics):
1. Access the Pump: The pump is usually located within the engine compartment, often under the cowl (the area under the windshield). You'll need to remove various components to reach it. This may involve removing:
* Cowl components: Expect to remove various plastic panels and covers to expose the wiper motor and pump mechanism. Be careful not to break any clips.
* Wiper arms and linkage: You'll probably need to remove the wiper arms from the wiper motor shaft. This usually involves loosening a nut at the base of each arm. Mark the position of the arms before removal to ensure proper reinstallation.
* Possibly the reservoir: Depending on your truck's configuration, you might need to partially or fully remove the washer fluid reservoir to gain better access to the pump.
2. Disconnect the Pump: Once you have access to the pump, disconnect the electrical connector(s) from the pump. There may be more than one depending on whether you have a single or dual-speed system. Take pictures or make notes to help with reassembly. Also disconnect the fluid lines. Be prepared for some fluid spillage; have rags handy.
3. Remove the Pump: The pump is usually secured with one or more screws or clamps. Carefully remove the fasteners and remove the pump from its mounting location.
4. Install the New Pump: Carefully install the new pump, ensuring that it's properly seated and aligned. Reconnect the fluid lines, ensuring they are securely attached and leak-free.
5. Reconnect Electrical Connections: Reconnect the electrical connectors to the new pump, making sure they are securely fastened.
6. Reassemble: Reassemble all components you removed in reverse order. Ensure that all plastic clips are properly reattached.
7. Test the System: Reconnect the negative battery terminal and test the system. Turn on the wipers to check for proper function. Check for leaks.
Important Considerations:
* Repair Manual: A repair manual specific to your 1998 Dodge Dakota is invaluable. It will provide detailed diagrams, torque specifications, and step-by-step instructions tailored to your vehicle.
* Professional Help: If you're not comfortable working on your vehicle, it's best to take it to a qualified mechanic. This job involves some disassembly and can be challenging for those lacking experience.
This is a general guideline; the specifics might vary depending on your truck's configuration. Again, refer to a repair manual for your specific 1998 Dodge Dakota model for precise and safe instructions. Improperly completing this task could lead to damage to your vehicle.
