2018 Hyundai Santa Fe water pump replacement cost

What a water pump replacement is like on the 2018 Hyundai Santa Fe

In 2018 Hyundai sold two different vehicles under this name, and it is the first thing that moves your quote. The Santa Fe badge went on the long-wheelbase three-row with the 3.3L Lambda II GDI V6 (renamed Santa Fe XL for 2019), while the two-row most people picture was the Santa Fe Sport with a 2.4L GDI or 2.0L turbo Theta II four. The pumps do not interchange: the V6 takes OE 25100-3C131, and both Sport engines share OE 25100-2GTA0, so a shop that looks up the wrong body style can be off by an engine and an hour of labor before the car is even on the lift.

The labor number is friendlier than most SUV water pumps because every 2018 engine here uses an external pump on the accessory-belt side, spun by the serpentine belt, with the timing chain untouched. On the 3.3L V6 the pump sits low on the passenger side of the transverse engine; the job is wheel and inner liner off, belt off, pulley unbolted, then the pump and its gasket, and OpenLaborProject books it at 2.8 hours with a 2.3 to 3.5 range. On the Theta II fours the pump hides behind the alternator against the frame rail, so the alternator usually comes out for clearance, and the drain, refill, and air-bleed eat as much clock as the pump itself. RepairPal's labor slice for this job on the Santa Fe runs $277 to $407, which brackets the same 2 to 3 hour reality.

The scary dealer quotes on this truck are a parts story, not a labor story. The genuine Hyundai pump lists at $447.55 for the V6 and $434.69 for the Sport engines (about $309 to $319 from discount OEM sites), and RepairPal's 2018-specific $891 to $1,201 estimate assumes $504 to $639 in parts, which is OE pricing plus markup. Meanwhile RockAuto sells the AISIN pump, an OE-tier Japanese supplier, for $45.79 (V6, WPK812) and $35.79 to $48.79 (fours, WPK823/WPK822), Gates runs $71.79 to $112.79, O'Reilly's Import Direct is $92.99, and AutoZone's lifetime-warranty Duralast 146-7460 for the V6 is $138.99. Same job, roughly $300 of the spread is just whose box the pump comes in.

Failure on these engines usually announces itself one of two ways in the 90k to 150k window: coolant weeping from the pump's weep hole, or a bearing growl that changes with engine speed. A light dry crust at the weep hole is normal seal behavior and not by itself a reason to replace; a wet drip, pooling, or repeated top-offs means the internal seal is done. Because the pump lives on the accessory drive, a leaking pump often soaks the serpentine belt, so budget a $20 to $40 belt if yours is contaminated. One more Sport-specific point: the 2.4L Theta II's famous rod-bearing recalls and extended engine warranty are an oiling issue that shows up as knock, not coolant loss, so a drip at the front of that engine is almost always this inexpensive pump job and not the engine saga.

Use the right coolant and insist on a proper bleed. The factory fill is Hyundai's phosphate-based OAT (Asian-vehicle formula); universal green or Dex-Cool style coolant is the wrong chemistry for this system. The V6 holds close to 10 quarts and the fours around 8, and a pump job typically needs 1.5 to 2 gallons of premix to refill what drains. Skipping the air-bleed on refill is the classic cause of a no-heat complaint or a temperature spike a week later, and the aluminum pump housing takes low torque values, so stripped bolt threads from gorilla hands are a known comeback on this job.

Estimate note: these are researched independent-shop ranges, not a guaranteed quote. The only exact number is one from a shop that has seen your car.
