Difficulty: Intermediate · About 25 min · Jeep Liberty
Replace the coolant overflow bottle on a 2002–2007 Jeep Liberty, handling coolant only with the engine fully cold and the system depressurized.
Tools you will need
- 10 mm socket and ratchet
- Slip-joint pliers
- Drain pan
Parts and supplies
- Coolant overflow bottle
- Vehicle-specified coolant
Steps
Prepare the cooling system
Park level and allow the engine to cool completely before opening the reservoir. Place a drain pan below the work area and never remove a cap from a hot or pressurized system.
Remove the old bottle
Clamp or contain the hoses only with suitable hose-safe tools, then release their clamps and disconnect them from the bottle. Remove the retaining nuts and lift the reservoir out without spilling coolant.
Install the replacement bottle
Connect the hoses to their matching ports and return the clamps to their original positions. Seat the bottle on its studs and install its retaining nuts securely.
Refill and inspect
Fill with the coolant specified for the vehicle to the cold-level mark and reinstall the cap. After the engine has completed a heat cycle and cooled fully, recheck the level and inspect for leaks.
Check your vehicle’s repair manual for exact specifications and fit.
