Difficulty: Intermediate · About 70 min · Volvo Xc90

Replace the upper radiator hose, including removing the skid plate, on a 2003-2012 Volvo XC90.

Steps

1. Remove the skid plate

   Raise and support the car, remove the two 14mm bolts on each arm of the skid plate and the long 14mm through bolt on each side, then lift and slide the skid plate forward to remove it.

2. Remove the old upper hose

   Open the coolant tank cap once the system is cool, open the radiator petcock to drain it, loosen the worm clamp on each end of the hose with a 7mm wrench, then pull it free from both fittings.

3. Install the new upper hose

   Slide the clamp over the hose, slide the hose onto the engine fitting, tighten the worm clamp with the 7mm wrench, then repeat on the radiator side.

4. Reinstall the skid plate

   Apply anti-seize to its bolt holes, lift it and slide its hooks over the subframe, align the hook and arm bolt holes, install the long 14mm bolts in front, then install the short 14mm bolts.

5. Refill the coolant

   Refill with a vacuum system if available, or add coolant to the reservoir and let it draw into the system, running the engine with the heat on and topping off the reservoir until it stays full.

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