🔧 Kona - Water Pump Replacement

On your Kona, “water pump” can mean the main engine-driven mechanical water pump or a separate electric auxiliary coolant pump (used for turbo/thermal management on some setups). The parts, access, and torque specs are different, so I need one quick detail before I give you the exact, trim-correct step-by-step.

Difficulty Level: Intermediate | Estimated Time: 2.5-5.0 hours

Quick question (pick one): Are you replacing the main mechanical water pump on the front of the engine, or the electric auxiliary coolant pump mounted in the coolant hose circuit?

⚠️ Safety & Precautions

• ⚠️ Never open the coolant cap hot; wait until fully cold.
• ⚠️ Support the vehicle securely if you’ll be working under it; never rely on a jack alone.
• ⚠️ Coolant is toxic; keep away from kids/pets and clean spills immediately.
• ⚠️ If you’re working near the radiator fan, disconnect the battery negative terminal to prevent unexpected fan operation.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm which “water pump” you’re replacing

• Look for coolant leakage location: front of engine behind the belt area usually points to the mechanical water pump.
• An electric auxiliary pump is a small electric unit in-line with coolant hoses (you’ll see an electrical connector).
• Reply with: “mechanical” or “electric”, and (if possible) upload a photo of the pump area.

Step 2: Pause here so I can give you the exact Kona procedure

• I’ll provide the correct removal order, bleeding procedure, and the OEM torque specs after you confirm pump type.

✅ After Repair

• Refill with the correct coolant mix and bleed air from the system (procedure depends on pump type and hose routing).
• Warm the engine and verify heat output is steady and the temperature gauge stays normal.
• Check for leaks around the pump, hoses, and clamps after the first drive and again the next morning.
