⚠️ Safety & Precautions

• ⚠️ Let the engine cool completely before starting; hot coolant can cause severe burns.
• ⚠️ Coolant is toxic; avoid skin contact and keep away from children and pets.
• ⚠️ Support the vehicle with jack stands if you raise it; never rely on a jack alone.
• ⚠️ Disconnect the negative battery cable to avoid accidental short circuits around the alternator and starter.
• ⚠️ Keep tools and fingers clear of pulleys and the belt path.
• ⚠️ Wipe up any spilled coolant immediately; it is slippery and dangerous underfoot.

📋 Before You Begin

• 🔧 Park the Equinox on level ground, set the parking brake, and put the transmission in Park.
• 🔧 Let the engine cool for at least 1–2 hours so the radiator hoses feel cool to the touch.
• 🔧 Open the hood and locate the coolant reservoir and radiator hoses so you know the coolant path.
• 🔧 Disconnect the negative battery terminal using a 10mm socket.
• 🔧 If you plan to raise the front, loosen the front wheel lug nuts slightly now using the correct lug wrench, then jack up and support the front with jack stands under the proper pinch weld/frame points.
• 🔧 Place the drain pan under the lower radiator area so it’s ready when you open the drain.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove engine covers and prepare access

• Remove the plastic engine cover by pulling up firmly at the corners; no tools are usually needed.
• If your Equinox has an upper radiator shield or intake duct over the radiator, remove any push clips with the trim clip remover tool and set the shield aside.
• Use a flathead screwdriver to loosen hose clamps on the air intake duct if it blocks access to the belt area, then remove the duct and set aside.

Step 2: Drain the coolant

• Position the drain pan under the lower right (passenger side) corner of the radiator.
• Slowly remove the coolant reservoir cap by hand to release any remaining pressure.
• Locate the radiator drain (petcock). Open it using your fingers or pliers (if needed) and let coolant flow into the pan.
• If no drain plug is present, loosen the lower radiator hose clamp with pliers or a flathead screwdriver and gently twist and pull the hose off to drain.
• After the flow slows to a drip, close the drain or refit the hose and tighten the clamp using pliers or flathead screwdriver.

Step 3: Remove the serpentine belt

• A serpentine belt is the long rubber belt that drives the alternator, water pump, and other accessories.
• Note or snap a photo of the belt routing so you can reinstall it correctly later. Photo saves confusion later
• Locate the automatic belt tensioner (spring-loaded pulley).
• Place a 15mm combination wrench or serpentine belt tool on the tensioner bolt and rotate it to release belt tension.
• While holding tension off with the tool, slip the belt off one of the upper pulleys by hand, then slowly release the tensioner.
• Remove the belt completely and set it aside; if it is cracked or glazed, replace it with a new one.

Step 4: Gain access to the water pump

• On the 1.5L engine, the water pump is mounted on the front of the engine where one of the pulleys was.
• Remove any plastic splash shield inside the passenger front wheel well if it blocks side access by removing clips with the trim clip remover tool and small bolts with the 10mm socket.
• Turn the steering wheel fully to one side for better wheel well access if needed.

Step 5: Disconnect hoses from the water pump (if equipped)

• Some pumps have a hose connection; others connect directly through passages in the engine block.
• If your pump has hose connections, use pliers to compress the spring clamp, slide it back on the hose, then gently twist and pull the hose off the pump.
• Use needle-nose pliers if space is tight.
• Let any remaining coolant drain into the drain pan.

Step 6: Remove the water pump pulley (if separate)

• If your pump has a separate pulley bolted to it, remove the small bolts holding the pulley using the appropriate 10mm or 13mm socket and ratchet.
• Hold the pulley from turning by hand or with a strap if needed while loosening bolts.
• Remove the pulley and set it aside.

Step 7: Remove the water pump

• Locate all the water pump mounting bolts around the pump body.
• Using the correct size socket (usually 10mm) and ratchet, loosen and remove all mounting bolts. Keep track of bolt locations and lengths.
• Gently tap the pump housing with the handle of a screwdriver to break the seal, then pull the pump away from the engine by hand.
• Be ready for more coolant to drain as the pump comes off.
• Do not pry hard against the engine aluminum surface to avoid damage.

Step 8: Clean the mounting surface

• Use a plastic scraper to carefully remove old gasket material or sealant from the engine where the pump was mounted.
• Wipe the surface with shop towels and a small amount of brake cleaner to make it clean and oil-free.
• Make sure no old gasket pieces fall inside the coolant passages. Stuff a clean rag in openings
• Remove the rag and double-check that the surface is smooth and clean.

Step 9: Prepare the new water pump

• Compare the new pump to the old one to make sure bolt holes and hose connections match.
• Install the new gasket on the pump. If it is a paper or rubber gasket, it usually installs dry; if the instructions call for RTV sealant, apply a thin, even bead as directed.
• Follow the instructions that came with the pump or gasket for any sealant drying time.

Step 10: Install the new water pump

• Carefully position the new pump against the engine, lining up the bolt holes.
• Install all the mounting bolts finger-tight to hold the pump in place.
• Using the appropriate socket and ratchet, snug the bolts in a crisscross pattern to evenly seat the pump.
• Use a torque wrench with the correct socket to tighten each water pump bolt to manufacturer specification (refer to a service manual or pump instructions) in a crisscross pattern.

Step 11: Reinstall the water pump pulley and hoses

• Place the pulley back on the pump shaft.
• Install the pulley bolts finger-tight, then tighten them evenly with the correct socket and ratchet.
• Hold the pulley from spinning while final tightening with the ratchet.
• Reconnect any coolant hoses to the pump, slide clamps back into position with pliers, and make sure they are secure.

Step 12: Reinstall the serpentine belt

• Route the new or reused belt following your photo or the belt routing diagram under the hood.
• Leave one upper pulley for last so you can slip the belt on easily.
• Rotate the belt tensioner using the 15mm combination wrench or serpentine belt tool to relieve tension.
• Slip the belt over the last pulley, then slowly release the tensioner.
• Check that the belt sits centered in all pulley grooves and is not twisted.

Step 13: Reinstall covers and shields

• Reinstall any wheel well splash shields using the 10mm socket and push clips using the trim clip remover tool to seat them fully.
• Reinstall the air intake duct and tighten clamps with the flathead screwdriver.
• Reinstall the engine cover by pressing it back onto its mounting points.

Step 14: Refill and bleed the cooling system

• Make sure the radiator drain is closed and all hoses are attached.
• Using a funnel, add the correct Dex-Cool compatible 50/50 coolant mix to the coolant reservoir up to the “FULL COLD” mark.
• Reconnect the negative battery cable using the 10mm socket.
• Start the engine and let it idle with the heater set to maximum heat and the blower on low. This helps move air out of the system.
• Watch the coolant level in the reservoir and add more as it drops, keeping it between “MIN” and “MAX.”
• Monitor engine temperature using the gauge or an OBD2 scan tool so it stays in the normal range.
• Once the engine reaches normal operating temperature and the heater blows hot air, shut off the engine and let it cool completely.
• After cooling, recheck the coolant level and top off to the “FULL COLD” mark if needed.

Step 15: Final checks and cleanup

• Inspect around the water pump, hose connections, and radiator for any signs of leaks.
• Check that the belt is tracking correctly and there are no unusual noises with the engine running.
• Pour the old coolant from the drain pan into sealed containers and take it to a recycling center or auto parts store that accepts used coolant. Never pour coolant on the ground

✅ After Repair

• ✅ Take a short test drive while watching the temperature gauge; it should stay in the normal range.
• ✅ After the drive, park, let the engine cool, and recheck coolant level and for any new leaks.
• ✅ Over the next few days, check under the vehicle for coolant drips and verify the coolant level remains stable.
• ✅ If the engine overheats, the heater blows cold, or you hear gurgling noises, there may still be air in the system; repeat the bleed process.
