🔧 QX60 - Radiator Hose Replacement
Replacing a radiator hose means draining some coolant, removing the old hose and clamps, then installing a new hose and refilling/bleeding the cooling system. This fixes leaks, prevents overheating, and avoids a roadside hose burst.
Difficulty Level: Intermediate | Estimated Time: 1.0-2.5 hours
Assumption: I’m covering both upper and lower radiator hoses (your steps match whichever hose you’re replacing).
⚠️ Safety & Precautions
- ⚠️ Never open the radiator cap on a hot engine; hot coolant can spray and burn you.
- ⚠️ Support the vehicle with jack stands if you lift it—never rely on a jack alone.
- ⚠️ Keep coolant off belts/alternator; wipe spills immediately.
- ⚠️ Coolant is toxic to people and pets—use a drain pan and sealed containers.
- ⚠️ Battery disconnect is not required for this job.
🔧 Required Tools
You'll need the following tools for this repair:
- Safety glasses

🔩 Required Parts
HowToo sells all the parts you need for this repair:
- Upper radiator hose - Qty: 1
- Lower radiator hose - Qty: 1
- Radiator hose clamps - Qty: 2-4
- Long-life engine coolant (blue, premixed 50/50) - Qty: 1-2 gallons
📋 Before You Begin
- Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
- Let the engine cool fully (radiator hoses should feel cool to the touch).
- Set the heater inside the cabin to HOT (this helps purge air later).
- If you need access from below for the lower hose, raise the front with a floor jack and support with jack stands.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Relieve pressure safely
- Put on safety glasses and nitrile gloves.
- Place a shop towel over the radiator cap, then slowly loosen it to the first stop to vent any leftover pressure.
- If you hear hissing, pause until it stops, then remove the cap fully.
Step 2: Drain coolant to below hose level
- Position a drain pan (10-quart minimum) under the radiator drain area.
- Use a flat-blade screwdriver (or by hand if it’s a wing-style) to open the radiator drain cock slowly and drain coolant.
- Drain until the level is below the hose you’re replacing (usually a few quarts), then close the drain cock snugly (do not overtighten).
Step 3: Remove covers/ducting for access
- If equipped, remove the top engine cover by pulling upward firmly (it’s held by rubber grommets).
- If the air intake duct blocks access, loosen the clamps with an 8mm socket and remove any clips using a trim clip removal tool, then lift the duct out.
Step 4: Remove the old hose clamps
- For spring clamps: squeeze the clamp ears with hose clamp pliers and slide the clamp back onto the hose.
- For worm-gear clamps: loosen with an 8mm socket or flat-blade screwdriver, then slide the clamp back.
- Tip: Take a quick photo before removal.
Step 5: Break the hose free (don’t damage the radiator neck)
- Twist the hose gently by hand to break the seal.
- If it’s stuck, slide a pick tool (small hook pick) under the hose end to let a little air in, then twist again.
- Pull the hose straight off the fitting.
Step 6: Clean and inspect the fittings
- Use shop towels to wipe the radiator neck and engine-side fitting clean.
- Check for cracks, heavy corrosion, or a damaged “bead” (the raised lip that helps hold the hose). If damaged, fix that before installing a new hose.
Step 7: Install the new hose and clamps
- Pre-position the new clamps on the new hose.
- Push the hose fully onto each fitting until it seats against the stop/bead.
- Reposition clamps:
- Spring clamp: use hose clamp pliers to place it over the sealing area (near the end of the hose, not hanging off).
- Worm clamp: tighten with an 8mm socket until snug; do not crush the plastic neck.
Step 8: Reinstall intake ducting/covers
- Reinstall the intake duct and tighten clamps using an 8mm socket.
- Reinstall any 10mm bolts removed using a 10mm socket.
- Press the engine cover back into the grommets.
Step 9: Refill coolant
- Insert a spill-free coolant funnel kit (specialty) into the radiator fill neck (this is a funnel that seals and helps burp air).
- Slowly add long-life engine coolant (blue, premixed 50/50) until full.
- Fill the overflow reservoir to the MAX line using a funnel.
Step 10: Bleed air from the cooling system
- Start the engine and let it idle with the radiator cap still off (funnel installed).
- Set the heater to HOT and fan to medium.
- Watch the funnel: as the thermostat opens, coolant level may drop—add coolant as needed.
- Gently squeeze the upper radiator hose a few times (with gloves) to encourage trapped air out.
- When bubbles stop and heat blows hot from vents, shut the engine off and let it cool, then top off and install the radiator cap.
✅ After Repair
- Start the engine and inspect both ends of the new hose for seepage.
- Test drive 10–15 minutes, then recheck for leaks.
- After the engine cools completely, recheck coolant level in the overflow tank and top off to MAX if needed.
- Dispose of old coolant properly (sealed container; take to a recycling center).
