2020 Hyundai Palisade Coolant in Peoria, AZ

Warning lights, temperature fluctuations, low coolant in the reservoir, sweet odors, or visible leaks signal it’s time to book a cooling system inspection.

Because the system operates under pressure, small issues can escalate in heat and traffic. Have the level checked cold and the system tested rather than relying on appearance alone. A professional pressure test helps pinpoint minor leaks before they become major repairs. Use schedule service to reserve a diagnostic visit.

• Temperature gauge rising under load or at idle
• Coolant puddles or crust at hose joints and the radiator
• Heater underperforming or fluctuating cabin heat

The service typically includes draining the old coolant, refilling with manufacturer-specified coolant, pressure testing, and inspecting hoses, radiator, cap, fans, and pump.

Technicians also verify thermostat function and airflow through the radiator and condenser. Findings are documented so you know exactly what was tested and what, if anything, needs attention. This approach helps maintain stable temperature control and corrosion protection in the 3.8L V6.

• Drain and refill with the specified coolant
• System pressure test to check for leaks
• Inspection of hoses, clamps, radiator, cap, and fans

The manufacturer publishes the maintenance schedule for this vehicle, and that schedule—confirmed at your service visit—sets the coolant change interval.

Because additives age independently of how the fluid looks, intervals aren’t based on color or appearance. Between scheduled replacements, technicians can test coolant condition and protection levels to determine if service is needed sooner. Follow the factory guidance and confirm with a quick test during routine maintenance.

• Refer to the owner’s manual schedule
• Request a coolant condition test at service
• Adjust based on results and driving conditions

The manufacturer specifies the correct coolant for this vehicle, and coolants are not interchangeable; do not rely on color as a guide.

Using the wrong formula can reduce corrosion protection and water pump life. At service, we refill with the exact type and concentration the manufacturer specifies for the Palisade to maintain designed performance and longevity. If you’re unsure what’s in your system, schedule service and we’ll test and correct as needed.

• Use only manufacturer-specified coolant
• Color does not indicate compatibility
• Technicians verify and fill to spec

Topping off restores level but does not renew depleted corrosion inhibitors, and a falling level points to a leak that should be inspected.

Only check levels when the engine is cold; the system is pressurized and hot after running. If the level keeps dropping, book an inspection to locate the source with a pressure test. A complete service ensures the correct mixture and additive strength throughout the system.

• Check coolant cold, never hot or under pressure
• Persistent loss indicates a leak
• Service restores protection and balance
