2023 Hyundai Santa Fe Plug-In Hybrid Coolant in Peoria, AZ

Warning lights, rising temperature readings, visible coolant leaks, sweet odors, or low coolant levels when checked cold indicate service is due.

Fluctuating cabin heat, gurgling sounds, or stained hose connections can also signal weak coolant or a leak. Because the system runs hot and under pressure, inspections should be performed by a technician once the engine is cool. Timely service helps prevent overheating and corrosion. If you’re unsure, we can test coolant condition during a visit.

• Dashboard temperature warnings or messages
• Puddles or crusty residue near the radiator, hoses, or pump
• Coolant level repeatedly dropping between checks

It includes draining and refilling with the manufacturer-specified coolant, pressure testing for leaks, and inspecting hoses, clamps, radiator, cap, pump area, fans, and thermostat.

Technicians confirm system pressure retention, proper fan cycling, and heater performance, then recheck levels after a cool-down. Using the correct coolant helps preserve corrosion protection and boiling-point control. This comprehensive approach supports reliable temperature management and component longevity.

• Drain and refill with the specified coolant for this vehicle
• System pressure test and cap inspection
• Checks of hoses, water pump area, radiator, fans, and thermostat

The manufacturer publishes the maintenance schedule for this vehicle, and that schedule determines when coolant should be replaced.

Because additives deplete over time, condition can also be verified by a coolant test during a service visit between scheduled intervals. Driving in extreme heat or frequent stop-and-go may justify checking condition more often. If you’d like guidance tied to your usage, we can test and advise at your appointment.

• Follow the official schedule for this model
• Test coolant condition between intervals as needed
• Consider local heat and driving patterns when planning

The manufacturer specifies a coolant type for this vehicle, and coolants are not interchangeable; color is not a reliable guide.

Using the correct formulation preserves corrosion protection and temperature control throughout the aluminum cooling system. Mixing types can reduce additive effectiveness and lead to deposits. Our team refills with the exact coolant specified for the 2023 Hyundai Santa Fe Plug-In Hybrid.

• Use only the type specified for this model
• Avoid mixing different coolant chemistries
• Do not choose coolant by color alone

Topping off only restores level and does not renew the additive package; a level that keeps dropping indicates a leak that needs inspection.

Because the system is hot and pressurized after running, checks should be performed cold and by a technician. If coolant is low, we’ll test for leaks, verify cap integrity, and assess condition. Book a visit so we can find the cause and correct it.

• Check and service the system only when cold
• Persistent level loss points to a leak, not normal use
• Testing ensures proper pressure and coolant health
