Dean McCrary Kia Service Center · Hattiesburg, MS · The Hub City
Kia EV9 Coolant Service
Exact-Spec Coolant · Battery-Thermal Loop · Never Mixed Types
Down where I-59, US-49, and US-11 all meet, Dean McCrary Kia keeps Pine Belt drivers moving — just a short drive from the downtown Hub sign, the Saenger Theatre, and the old train depot. With no engine to overheat, the EV9 instead relies on coolant circulating through a battery-thermal loop that holds the high-voltage battery in its ideal range for driving distance, performance, and longevity. We inspect, top off, and refill with genuine Kia Long-Life Coolant matched to that system — never mixing types. Expect factory-trained technicians and honest upfront pricing — plus automatic logging against your factory warranty coverage, all handled right here at our Hattiesburg service center.

How Often Does Your EV9 Need Coolant Service?
How Often the EV9's Battery-Thermal Coolant Needs Changing
With no engine, the EV9 has no engine coolant to worry about — instead, a battery-thermal coolant loop keeps the high-voltage battery within its ideal temperature range. According to the Kia EV9 maintenance schedule, plan on the first change at 120,000 miles or 120 months, then roughly every 24,000 miles after that (MEDIUM-HIGH confidence, one company-wide Kia EV/HV-coolant pattern — the same figures cited on the EV6's coolant page).
We still check the level at every visit — a low reading between changes can signal a slow leak well before the scheduled service comes due, and Pine Belt summer heat puts extra demand on the battery-thermal system.
Warning Signs Your EV9 Needs Coolant Service
No need to wait for the next service sticker if you notice any of these — bring your EV9 in:
A low coolant warning light lit up on the dash
A battery-temperature warning message on the display
Charging or DC fast-charging speed that’s slower than normal
Coolant spots visible under the car
Coolant that appears rusty, cloudy, or has debris floating in it
Which Coolant Service Does Your EV9 Need?
Not every coolant visit looks the same. Here’s a side-by-side of the three service levels — your advisor will recommend the right one after checking your level and condition.
Top-Off
For a slightly low level
Genuine Kia Long-Life Coolant, nothing else
A quick, affordable fix for minor loss

Inspection
Included free at every visit
We check level, color, and contamination
We check hoses and fittings for wear

Scheduled Service
Kia Long-Life Coolant (Genuine)
120,000 mi / 120 mo first, then ~24,000 mi
Full-spec, fresh corrosion inhibitors
Keeps the battery pack’s cooling components protected
Keeps your factory warranty record up to date
We never mix coolant types or colors — if your battery-thermal loop needs more than a genuine top-off, ask your advisor about a full service visit.
Why Trust Dean McCrary Kia With Your Coolant?
The wrong coolant, or coolants mixed together, can cause corrosion that’s costly to reverse. Here’s what only your Kia dealer delivers.
Kia-Trained Service Technicians
Our technicians know precisely which coolant spec the EV9’s battery-thermal system was engineered around.
Only Genuine Kia Long-Life Coolant
Exact-spec coolant every time, with types and colors never mixed. Generic coolant is a top cause of internal corrosion.
Free Recall & Software Checks
Open recalls, service campaigns, and control-module software updates all require a Kia dealer to perform. We check for all three on every visit. Check your recalls — no charge, for any Kia owner across the Pine Belt.
Factory Warranty, Logged Automatically
Every visit gets logged automatically against your factory warranty requirements — nothing to save, nothing to explain later — a system Kia owners across the Pine Belt rely on.
Straightforward, Upfront Pricing
We check level and condition first and quote second — you approve the work before anything starts, with no surprise add-ons at checkout.
We Know What Every Kia Calls For
Servicing hundreds of Kias a month — gas, hybrid, and electric — means we know exactly which coolant spec your EV9 needs — and won’t risk mixing it with the wrong type.
Coolant Service Questions, Answered
How Much Does Kia EV9 Coolant Service Cost?⌄
Pricing for Kia EV9 coolant service at Dean McCrary Kia depends on how much coolant is needed. Pick your Kia EV9 above to view current pricing and coupons — Military and First Responder discounts are available with valid ID and stack right on top of current service pricing.
How Often Does the EV9’s Battery-Thermal Coolant Need to Be Changed?⌄
According to the Kia EV9 maintenance schedule, the first battery-thermal coolant change comes due at 120,000 miles or 120 months, then roughly every 24,000 miles after that (MEDIUM-HIGH confidence). Since the EV9 has no engine, there's no separate engine coolant system to worry about — but we still check coolant level at every visit.
Can I Mix Different Types of Coolant in My Kia EV9?⌄
No. Mixing coolant types or colors, even ones that look alike, can break down the system's corrosion inhibitors and lead to internal corrosion. Stick to the genuine Kia-specified coolant for top-offs, and if you're ever unsure what's already in the system, have it flushed rather than risk mixing it.
What Does Genuine Kia Long-Life Coolant Do Differently?⌄
Genuine Kia Long-Life Coolant is built to the exact corrosion-inhibitor and freeze/boil-point spec the EV9's battery-thermal system was designed around, guarding the battery pack's cooling components against corrosion in ways generic coolants aren't always rated to match.
What Are the Signs My Kia EV9 Needs Coolant Service?⌄
A low coolant warning light, a battery-temperature warning message, coolant spots visible under the car, or slower charging and DC fast-charging speed can all signal a battery-thermal coolant issue worth having inspected.
Can I Finance My Kia EV9 Service?⌄
Yes — Dean McCrary Kia offers service financing, so you can service now and pay later. Break your coolant service, brake job, or any repair into monthly payments — the application only takes about a minute at check-in, and checking your options won’t touch your credit score.

“What a wonderful place. You pull into a lovely covered garage to reach the service desk, so you’re never out in the rain, and they bring your car back around for you when they’re done. Lovely people — I’m very happy I get to go there for my oil changes. Couldn’t recommend them more.”

“After a wreck totaled my Sorento, I came to Dean McCrary to get another one. Daniel Saucier was my salesperson and he made things so easy and seamless! I ended up leaving in a brand-new 2026 Sorento that I love even more. Thanks Daniel!”
