⚠️ Safety & Precautions

• ⚠️ Never open the radiator cap or hoses on a hot engine. Let the engine cool completely (at least 1–2 hours).
• ⚠️ Coolant is poisonous. Avoid skin contact and keep away from kids and pets.
• ⚠️ Support the front of your Rogue securely with jack stands. Never work under a car held only by a jack.
• ⚠️ Avoid spilling coolant on the drive belt or electrical connectors.
• ⚠️ Do not run the engine with low coolant; it can overheat quickly and cause engine damage.
• 🔋 Battery disconnect is not required for this repair.

📋 Before You Begin

• Park your Rogue on level ground, set the parking brake, and put the transmission in P.
• Let the engine cool completely. The upper radiator hose should feel cool to the touch.
• Turn off the climate control and ignition, remove the key.
• Place wheel chocks behind the rear tires.
• Open the hood and locate the upper and lower radiator hoses so you know what you’re changing.
• Have your drain pan and rags ready before loosening anything that can leak coolant.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Lift and secure the front of your Rogue

• Use the floor jack on the front center jacking point (under the subframe crossmember) to raise the front of your Rogue.
• Place jack stands under the left and right pinch welds (just behind the front wheels).
• Lower the vehicle gently onto the jack stands using the floor jack, then slightly shake the car at the fender to confirm it is stable.
• Never crawl under a car supported only by a jack.

Step 2: Remove the lower engine splash shield

• Position the coolant drain pan under the front center of the engine bay.
• Use the 10mm socket and ratchet to remove any bolts holding the plastic splash shield.
• Use the plastic trim clip remover to pop out the plastic clips. If they break, you’ll replace them later.
• Lower the splash shield and set it aside.

Step 3: Relieve any remaining system pressure

• With the engine still cool, use a clean rag over the radiator cap (on the plastic reservoir) and slowly twist it open.
• If you hear a hiss, stop and let the pressure bleed off, then continue opening.
• Set the cap aside in a clean spot.

Step 4: Drain enough coolant

• On the bottom of the radiator (usually right side), locate the drain plug (also called a “petcock”).
• Position the coolant drain pan directly under it.
• Use the flathead screwdriver to carefully turn the plastic drain plug counterclockwise to open it.
• Allow coolant to drain until the flow slows significantly. You don’t need to fully empty the system if only replacing hoses, but expect ~1–1.5 gallons.
• Once drained enough, use the flathead screwdriver to gently close the drain plug. Do not overtighten. Torque to about 2–3 Nm (hand snug only).
• Do not force the plastic drain plug.

Step 5: Remove the upper radiator hose

• From the top, follow the upper hose from the radiator to the engine.
• Use the hose clamp pliers to squeeze the spring clamp at the radiator end and slide it back along the hose a few centimeters.
• At the engine end, repeat with hose clamp pliers to move that clamp back as well.
• If your Rogue has screw-type clamps instead, use the flathead screwdriver to loosen the screw until the clamp can slide.
• Gently twist the hose at the radiator connection by hand to break it loose. If it is stuck, carefully slide the flathead screwdriver under the hose edge to break the seal, but don’t gouge the plastic neck.
• Pull the hose off the radiator and aim it into the coolant drain pan to catch any remaining coolant.
• Repeat to remove the hose from the engine side.

Step 6: Remove the lower radiator hose

• From underneath, locate the lower hose running from the bottom of the radiator to the water pump/engine.
• Use the hose clamp pliers to compress the clamp at the radiator end and slide it back.
• Do the same for the engine end clamp with the hose clamp pliers or flathead screwdriver if it is a screw clamp.
• Gently twist the hose at each connection to break it free. Use the flathead screwdriver carefully if it is stuck.
• Pull the hose off, directing any draining coolant into the coolant drain pan.

Step 7: Clean the hose connection surfaces

• Use a clean rag to wipe the radiator necks (upper and lower) and the engine hose connection points until they are smooth and clean.
• If any piece of old hose is stuck, carefully cut it lengthwise with the utility knife and peel it off instead of prying hard.
• Clean, smooth surfaces help prevent future leaks.

Step 8: Install the new upper radiator hose

• Slide the new hose clamps onto the new upper hose before installing it.
• Push one end of the new upper hose fully onto the radiator neck by hand until it seats against the stop.
• Position the clamp near the bulge or bead on the neck and tighten:
• If using a spring clamp: use the hose clamp pliers to compress and slide it into place, then release.
• If using a screw clamp: use the flathead screwdriver to tighten until snug. Torque to about 3–4 Nm (hand snug, do not strip).
• Route the hose as originally installed (no twisting or kinks) and push the other end onto the engine side fitting.
• Position and tighten that clamp the same way.

Step 9: Install the new lower radiator hose

• Slide clamps onto the new lower hose.
• From underneath, push the hose onto the engine-side fitting first until fully seated.
• Use the hose clamp pliers (spring clamp) or flathead screwdriver (screw clamp) to tighten the engine-side clamp. Torque to about 3–4 Nm (hand snug).
• Route the hose to the bottom of the radiator with the same shape as the old hose. Make sure it does not rub on any pulleys or belts.
• Push the hose fully onto the radiator neck and secure the clamp.

Step 10: Double-check all connections

• Inspect each clamp (four total) to ensure it is sitting behind the bead on the fitting and is evenly tightened.
• Make sure no hose is twisted, kinked, or touching sharp edges.
• Confirm the radiator drain plug is closed with the flathead screwdriver.

Step 11: Refill the cooling system

• Place the funnel in the radiator reservoir/degassing tank opening.
• Slowly pour Nissan-spec blue coolant (50/50 mix with distilled water if concentrate) into the reservoir until it reaches the “MAX” line.
• Pause a few times to let air bubbles work out as the system starts to fill the engine and hoses.
• Pour slowly to reduce trapped air.

Step 12: Bleed air from the system (warm-up procedure)

• Leave the radiator cap off for now.
• Start the engine and let it idle. Turn the heater inside the cabin to HOT with the fan on low (this helps bleed the heater core).
• Watch the coolant level in the reservoir. As the engine warms, coolant level may drop—add more through the funnel to keep it near the “MAX” line.
• When the engine reaches operating temperature, you should feel the upper radiator hose get warm, and you may see small bubbles coming up.
• After bubbles slow down and the level stabilizes, top off as needed to the “MAX” line.
• Carefully install the radiator cap by hand and tighten it firmly.

Step 13: Check for leaks

• With the engine still idling, look at all four hose connections (top and bottom of radiator, engine ends) from above and below.
• Use a clean rag to wipe around each connection and check for any fresh wetness.
• If you see a slow drip, turn off the engine and carefully tighten that clamp a little more using the hose clamp pliers or flathead screwdriver.

Step 14: Reinstall the splash shield and lower the vehicle

• Once there are no leaks, reinstall the lower splash shield.
• Use the 10mm socket and ratchet to reinstall bolts and the plastic trim clip remover to press in new or existing clips.
• Use the floor jack to lift the front slightly, remove the jack stands, then lower the Rogue fully to the ground.

Step 15: Final coolant level check

• With the engine off and slightly cooled (15–30 minutes), check the coolant level in the reservoir again.
• Top up to the “MAX” line if needed using the funnel.
• Properly pour old coolant from the coolant drain pan into sealed containers for safe disposal at a recycling center or shop.

✅ After Repair

• 🧪 Take a short test drive (10–15 minutes), using both city speeds and a bit of highway if possible.
• Watch the temperature gauge. It should stay in the normal middle range. If it climbs high, stop immediately and shut off the engine.
• After the drive, park, let the engine cool at least 30–45 minutes, then re-check for leaks around all hose connections.
• Re-check coolant level in the reservoir the next morning when the engine is fully cold; top off to “MAX” if needed.
• No scan tool or special reset is required for this repair on your Rogue.
