2016 Sorento 2.4L G4KJ Water Pump — OEM 25100-2G500
The third-gen Sorento 2.4L Theta II water pump is mounted to the timing chain cover and driven by the timing chain. This is an internal pump — the timing cover must be removed for access, making it a 4–6 hour job.
OEM water pump: Kia 25100-2G500; aftermarket: Aisin WPK-824 or GMB 145-2360.
The pump is behind the timing chain cover — remove the valve cover, crank pulley, and cover assembly.
Pump bolts (5x): M8 x 1.25 x 30mm; torque to 18 ft-lb. The pump seals with an O-ring, not a gasket.
O-ring seal: Kia 25124-2G000; coat with clean coolant before installing to prevent pinching.
Timing chain tensioner: Kia 24410-2G000; replace while exposed — do not reuse a decompressed tensioner.
Coolant capacity: 7.8L (8.2 qt); use genuine Kia Long Life Coolant (green) or equivalent HOAT.
Crankshaft bolt: 22mm; torque to 111 ft-lb plus 90° angle torque. Use a new bolt (Kia 23124-2G400).

Check the procedure for your vehicle
A year and model alone may not identify the correct repair. Match the engine, drivetrain and equipment to the service manual before using the overview below.
Match your vehicle
Check the VIN, engine and drivetrain against the manual. Different configurations can use different components and procedures.
Confirm the service details
Use the matching service procedure for access, fastener specifications and service sequence. General time and cost estimates do not establish applicability.
Manual and spec cross-checks
Use the linked manual and spec paths to verify fitment, torque, and service order before teardown.

- •Sorento water-pump pages spiked more than once during the run-up, especially older-year variants
- •Use this page to call out engine verification because Sorento engine families vary widely by year
- •A coolant smell with no visible leak may still point to weep-hole seepage at the pump
- •If a timing-belt engine is involved, pair the pump with timing service work
Pump hardware torque varies by engine
Safety Warnings
- •Sorento pump jobs vary significantly by engine, so verify the exact engine before ordering parts
- •Do not continue driving an overheating Sorento after a pump failure - head damage happens quickly
- •Inspect idlers and the drive belt whenever you are deep in the accessory drive

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
What the Pros Prefer: 2016 Kia Sorento Water Pump Workflow
Controlled coolant capture, mating surface prep, and cooling system purging.
Pulley Bolt Pre-Loosening & Coolant Drain
Shop Tip:Loosen the water pump pulley mounting bolts 1 turn while the serpentine belt is still under full tension. The belt grip prevents the pulley from spinning freely in your hand.
Pump Extraction & Catch Pan Placement
Shop Tip:Place your drain bucket directly beneath the pump before unbolting. Significant trapped coolant remains behind the pump cavity even after draining the radiator.
Mating Surface Decontamination
Shop Tip:Scrape all residual paper and dried RTV until the aluminum surface is clean, smooth, and dry. Wipe with brake cleaner so the new gasket bonds flat.
Torque Pattern & Air Bleed Funnel
Shop Tip:Small M6 and M8 water pump bolts have low torque ratings (7–15 lb-ft). Overtightening snaps bolts in the block. Use a spill-free funnel to purge air pockets on refill.
