2018 Toyota Highlander water pump replacement: parts and labor
Labor runs $385 to $1,070 (the job takes 2 to 4 hours at typical independent-shop rates), and the water pump itself typically costs $95 to $230 for the 2018 Toyota Highlander, plus $30 to $80 in coolant (toyota pink sllc) + shop supplies. Prices updated September 2026.
| Engine | Parts | Labor | Estimated total |
|---|---|---|---|
| 3.5L V6 | $110 to $230 | $495 to $1,070 (4.5 to 6.5 hrs) | $635 to $1,380 |
| 2.7L I4 | $95 to $180 | $385 to $825 (3.5 to 5.0 hrs) | $510 to $1,085 |
Coverage note: 2018 Highlander Hybrid (3.5L 2GR-FXS): it does keep a belt-driven water pump, but high-voltage system precautions, the separate inverter coolant pump that often gets quoted alongside, and hybrid-shop labor rates push its quotes outside the gas-engine range, so including it would distort the estimate.
RepairPal shows $947 to $1,269 for this job ($366 to $416 parts, $581 to $853 labor) and KBB's 2018 fair range is $750 to $1,236 with parts listed at $441 to $497. Both price the pump at OEM list plus heavy markup, three to four times the $90 Aisin street price for the identical OE-supplier part, and assume near-dealer labor rates. Real dealer quotes run $1,500 to $1,800. An independent shop billing an Aisin or online-OEM pump lands in the $635 to $1,380 range shown here, with most jobs clustering around $850 to $1,100.
Where these numbers come from
- Estimate ranges: a hand-verified research pass for this exact vehicle and repair, cross-referenced across 12 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 Toyota Highlander 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: Serpentine drive belt and tensioner (commonly recommended at the same time, roughly $25 to $60 in parts), Thermostat replacement, often bundled while the mount is off, Radiator, hoses, or heater core work if the leak turns out to be elsewhere, Diagnostic or pressure-test fee if charged separately, Highlander Hybrid work (excluded, see variant note), Taxes, shop fees, and hazmat coolant disposal beyond basic supplies.

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 Toyota Highlander
The 2018 Highlander splits two ways: almost every trim runs the 3.5L 2GR-FKS V6 (295 hp, D-4S port plus direct injection, 8-speed automatic), while the base LE FWD could be had with the 2.7L 1AR-FE four and a 6-speed. Both engines drive the water pump off the serpentine belt, and on both the pump hides behind the right-side engine mount and its bracket. The shop has to support the engine from underneath, unbolt the mount and bracket, and thread the pump out of a tight gap between the timing cover and the frame rail. That is why a pump that costs about $100 carries 4.5 to 6.5 book hours on the V6. FWD versus AWD changes nothing here since the pump sits up front on the transverse engine, so the labor spread is mostly shop rate and how rusty the mount hardware is.
Classic failure on the 2GR family is pink Super Long Life coolant seeping from the weep hole onto the belt side of the engine, sometimes with a bearing growl at idle. On 2017 to 2019 Highlanders owners report seepage anywhere from about 60k to 120k miles; one documented 2018 at 69,000 miles had the pump replaced for $858 all-in, which is a fair real-world midpoint for an independent shop. A small dry weep track of dried pink residue is normal on these pumps; steady dripping or coolant loss is what actually condemns them.
Part numbers matter on this truck. The V6 takes Toyota 16100-39616 (2017 to 2019 Highlander only, not the older 2GR-FE pump), which runs $128 to $137 from online Toyota dealers against a $175 to $191 MSRP. The 2.7L uses 16100-39515, about $94 online. Aisin builds the OE pump, and the aftermarket Aisin unit for the 2017 to 2022 3.5L sells for around $90 at PartsGeek while the WPT-194 for the four cylinder is about $72. Skipping the $40 no-name eBay pump is worth it here because a comeback means paying the 5-hour access job twice.
Myth-bust: some part-site guides claim 8 to 10 hours and an engine lift for this job. Actual labor guide times for the Highlander V6 pump run about 4.4 to 6.5 hours (4.7 on earlier 2GR trucks, 6.3 quoted for some model years), and no engine removal is required, just the mount and bracket. Also, the 2GR-FKS has a timing chain, not a belt, so there is no timing belt to bundle in. What smart shops do bundle is the serpentine belt (roughly $25 to $60) and often the thermostat, since both are staring at you with the mount off.
Dealer quotes on 2017 to 2019 Highlanders for this exact job have come in at $1,500 to $1,800, roughly double what a good independent charges with an Aisin pump. On the 2.7L LE the same style of job runs about an hour less because there is less packed around the mount, which is why its row prices lower even though the pump itself costs nearly the same.
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 Toyota Highlander water pump replacement cost?
A 2018 Toyota Highlander water pump replacement typically runs $510 to $1,380 at an independent shop, parts and labor included. The water pump itself is $95 to $230, 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 Toyota Highlander 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 Toyota 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 Toyota 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 Toyota 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 Toyota Highlander?
Yes, NHTSA lists 5 recalls for the 2018 Toyota Highlander. 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.
