2018 Chevrolet Equinox water pump replacement: parts and labor
Labor runs $330 to $765 (the job takes 2 to 4 hours at typical independent-shop rates), and the water pump itself typically costs $40 to $410 for the 2018 Chevrolet Equinox, plus $20 to $45 in dex-cool 50/50 coolant (1-2 gal) plus disposal and s. Prices updated September 2026.
| Engine | Parts | Labor | Estimated total |
|---|---|---|---|
| 1.5L I4 Turbo | $40 to $150 | $330 to $675 (3.0 to 4.5 hrs) | $390 to $870 |
| 2.0L I4 Turbo | $50 to $150 | $385 to $765 (3.5 to 5.1 hrs) | $455 to $960 |
| 1.6L Turbodiesel | $115 to $410 | $330 to $675 (3.0 to 4.5 hrs) | $465 to $1,130 |
A GM Genuine/ACDelco pump runs about $130 online but $170-225 at retail (AutoZone lists the GM 55513550 kit at $222.99), and dealer labor at $165-200/hr against the 4.5-5.1 hour book time pushes dealer totals to roughly $900-1,400. That parts-counter markup plus rate difference, not a different procedure, is most of the gap versus the independent range shown here.
Where these numbers come from
- Estimate ranges: a hand-verified research pass for this exact vehicle and repair, cross-referenced across 13 independent sources (parts retailers, labor guides, and published shop pricing), completed September 2026.
- Recall and complaint data: NHTSA (National Highway Traffic Safety Administration) records for the 2018 Chevrolet Equinox specifically, filtered to cooling system relevance and refreshed daily from the federal API.
- Local prices: real, accepted quotes from verified Fixxr marketplace jobs, published per metro once five verified jobs of this type have closed. Never estimates dressed up as transactions.
Not included in the estimate: Diagnosis and cooling-system pressure-test time (often 0.5-1.0 hr billed separately), Thermostat, radiator hoses, and serpentine belt, which are commonly replaced with the pump, Water pump housing on the 1.5L if it is the part actually cracked or leaking (TSB 18-NA-335), Full coolant system flush (estimate assumes drain and refill only), Sales tax, shop supplies, and hazardous-waste disposal fees.

Real owner report, verbatim from NHTSA:
“My 2018 Equinox is failing California Smog due to an incorrect CVN error code, which is covered under Emissions Recall N212345540 or N202298780 and the dealership is refusing to reflash it and asking me to pay for a full diagnostics when there is no check engine light on. I also had a full diagnostic run on June 2nd $289.99 which confirmed this code and referred me to the BAR Referee who also confirmed this is causing the issue.”
Worth knowing: the radiator is one of the most common causes of overheating, alongside the thermostat, water pump, and hoses. Get the real source confirmed before you approve any repair, so you fix the part that actually failed.
Recall fixes are free at the dealer. Everything else deserves a fair price.

The water pump is one piece of a loop. Here is how the parts work together, so you understand exactly what your car is doing and why.
Found a puddle? What the color tells you
Bright green
Classic coolant leak. Find the source before it overheats.
Orange / pink
What most modern vehicles use (OAT). Same urgency as green.
Rusty brown
Old, corroded coolant. Overdue for a flush.
Milky / oily
Coolant mixing with oil, like a coffee milkshake. Can mean a head gasket. Serious.
What a water pump replacement is like on the 2018 Chevrolet Equinox
The 2018 Equinox is the first year of the third generation, and every 2018 water pump is an external, serpentine-belt-driven unit. That is a genuine break from the 2010-2017 Equinox 2.4L, whose pump was driven by the balance-shaft chain and made the old truck famous for four-figure water pump bills, special sprocket-holding tools (Lisle 13800), and exhaust removal for access. Even so, the 2018 is not a quick job in a tight transverse bay: labor-guide data quoted for this exact vehicle puts the 1.5L at about 4.5 hours and the 2.0L at 5.1 hours, while community flat-rate data (Open Labor Project) runs 2.3-3.5 hours. The spread is real, so the table uses 3.0-4.5 hours (1.5L) and 3.5-5.1 hours (2.0L): the pump hides behind the drive belt and engine-mount side of the bay, the cooling system has to be drained and bled, turbo and thermostat plumbing crowd the access (tech videos on the 2.0L LTG show pulling the thermostat and belt tensioner just to reach pump bolts), and GM uses torque-to-yield pump bolts that must be replaced, not reused.
Failure pattern on the 1.5L (LYX) is well documented across the shared small-gas-engine family (Cruze, Malibu, Equinox, Terrain): the shaft seal starts seeping at the weep hole, leaving crusty orange or white Dex-Cool residue and a low-coolant or coolant-smell complaint, often with a whine or rumble that tracks engine RPM. A NHTSA complaint on the 2018 (ODI 11716625) describes exactly this at about 75,000 miles, and the typical failure window reported is roughly 60,000-100,000 miles. Do not limp it: the 1.5L turbo has a poor tolerance for overheating, and cooked 1.5s frequently graduate to head gasket, oil-consumption, or full engine-replacement territory that dwarfs a water pump bill.
Part numbers worth knowing: the 1.5L pump is GM 12667387 (sold widely, with later supersessions such as 12735409); it bolts into a separate water pump housing on the block, and GM TSB 18-NA-335 (Jan 2019, covering 2018-2019 Equinox plus Cruze/Malibu/Spark/Volt) was issued because techs kept replacing pumps when the actual leaker was the housing. Have the shop inspect the housing before buying parts; aftermarket sells pump-only (Gates 41218 about $67, GMB about $40, Dayco about $62) and pump-with-housing versions (GMB with housing and oil cooler about $193). The 2.0L LTG pump likewise comes with or without the back housing and thermostat housing (Gates 43071 about $70 vs 43071BH about $150; ACDelco 2521009 about $75; GM 251781 kit with thermostat about $193), so quotes can honestly differ by $100 on parts alone. The 1.6L diesel (LH7) was sold in the US for only 2018-2019, so the aftermarket barely exists: the GM Genuine 55513550 kit with thermostat is actually the cheap option at about $118, with OE-supplier Pierburg at about $411.
Myth-busting the dealer quote: RepairPal's Equinox all-in range is $943-1,281 and YourMechanic's 2018-specific estimates run $1,256 (2.0L) to $1,849 (1.5L), figures built on OE-grade parts pricing and blended with the miserable old 2.4L labor. An independent shop installing a Gates/GMB/Dayco pump on a 2018 has no reason to be near the top of that range on the gas engines. Also, if the complaint is no cabin heat at idle, check the small electric auxiliary heater pump first (GM 251814, about $69 part); it is a much cheaper repair than the main pump and a common misdiagnosis on these cars. Whatever gets installed, this platform requires Dex-Cool OAT coolant only, and the system needs a proper vacuum-fill or bleed to avoid air-pocket overheating on the first drive.
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.
Frequently asked questions
How much does a 2018 Chevrolet Equinox water pump replacement cost?
A 2018 Chevrolet Equinox water pump replacement typically runs $390 to $1,130 at an independent shop, parts and labor included. The water pump itself is $40 to $410, labor makes up most of the rest, and the job takes 2 to 4 hours.Why does the price change with the engine?
The 2018 Chevrolet Equinox came with more than one engine, and they do not share the same part or the same access. A tighter engine bay or extra teardown adds labor hours, and the part price moves too. Sites that show one national number flatten that out. Pick your engine on the estimate above for a closer figure.Is it always the water pump when my Chevrolet overheats?
No. Overheating can also be a stuck thermostat, a clogged or leaking radiator, a failed cooling fan, or simply low coolant. What points specifically at the water pump is coolant dripping from the weep hole under the pump, a grinding or whining noise from the front of the engine, or wobble in the pump pulley. Because these causes look identical from the driver's seat, get a real diagnosis before approving the repair.Can I drive my Chevrolet with a bad water pump?
Only far enough to get it looked at. A failing pump stops circulating coolant, the engine overheats, and driving an overheating Chevrolet risks a warped cylinder head or a blown head gasket, a $3,000 to $8,000 repair on top of the pump. If the temperature gauge climbs or you see steam, pull over and let it cool. If it keeps overheating, tow it.Should the thermostat be replaced at the same time?
Usually yes, and most shops will suggest it. The cooling system is already drained and opened for the water pump, so the thermostat adds only a small part cost with little extra labor, and a stuck thermostat is one of the most common follow-on failures. Replacing both in one visit avoids paying the teardown labor twice.How long does a water pump last?
Most factory water pumps last roughly 100,000 to 150,000 miles. The usual failures are the shaft seal, which starts seeping coolant from the weep hole, and the bearing, which gets noisy before it lets go. Regular coolant changes protect the seal and are the cheapest way to extend pump life.Are there recalls on the 2018 Chevrolet Equinox?
Yes, NHTSA lists 5 recalls for the 2018 Chevrolet Equinox. Recall repairs are done free of charge at a franchised dealer for that brand, so it is worth checking your VIN before paying a shop for related work.
