  Q: How Do You Remove and Install the Coolant Reservoir?

  A: To address potential cooling system issues, start by troubleshooting if the engine overheats and the cooling fan isn't functioning. To test the fan motor, disconnect its electrical connector and use jumper wires to connect it directly to the battery and ground. Replace the motor if it doesn't work. This applies to both fans in these models. If the radiator fan motor is fine but doesn't engage when the engine heats up, consider defective fan relay(s). Locate fan relays in the engine compartment fuse/relay box, noting an additional small relay box in the area behind the condenser fan for 2007 and later models. Test the relays and, if they're functional, proceed to test the radiator fan switches. For 2003 and earlier models, utilize fan switches; for later models, Engine Coolant Temperature (ECT) sensors replace the switches. The switches, controlling fan operation based on temperature, can be tested with an ohmmeter to detect continuity at specific temperatures. If relay(s) and fan switch check out, inspect wiring and connections to the fan motors, seeking professional repair if necessary. For replacement, disconnect the battery, raise the vehicle, remove the lower splash shield, and drain the cooling system if needed. Proceed by removing the radiator cover, coolant reservoir, and upper radiator hose. If working on the air conditioning condenser fan (right side), disconnect the reservoir hose, remove the mounting bolt for 2004 and later models, and lift the reservoir out for cleaning or replacement if cracked. Install the reservoir in reverse order.
