Replace the lower radiator hose on a Volvo XC90 after the engine cools, then refill and bleed the cooling system carefully.

Steps

1. Raise the vehicle and remove the shield

   Let the engine cool fully before opening the cooling system. Raise and support the vehicle, then remove the skid plate fasteners and lower the shield.

2. Drain coolant and remove the hose

   Place a drain pan below the radiator and open its drain valve. Loosen the lower hose clamps at the radiator and engine, then remove the hose and clear nearby intake parts as needed.

3. Install the new hose

   Seat the replacement hose fully at both ends and position the clamps behind the hose beads. Reinstall the intake components and skid plate.

4. Refill and bleed the system

   Close the drain and refill with the specified coolant using the vehicle's bleed procedure. Run the heater while monitoring temperature and level, allow the engine to cool, then recheck for leaks and correct level.

Check your vehicle’s repair manual for exact specifications and fit.
