2018 Ford Flex Coolant in Mesa, AZ

Common signs include a rising temperature gauge, visible leaks or low coolant level, a sweet odor, or warning lights.

Temperature fluctuation, heater performance changes, or dried crust near hose connections also suggest attention is due. Because the system runs hot and under pressure, check levels only when the engine is cold. If the level keeps dropping, that points to a leak rather than normal consumption. A professional inspection and fluid test confirm the next step.

• Rising temp gauge or overheating under load
• Coolant spots under the vehicle or a sweet smell
• Frequent top‑offs or poor cabin heat at idle

The service drains aged coolant, refills to the manufacturer’s spec, bleeds air, pressure‑tests for leaks, and inspects caps, hoses, fans, and related components.

Technicians verify operation at temperature and recheck levels after circulation. They also look for residue that indicates past seepage and assess belt and hose condition where visible. Results are documented so you know what was found and what, if anything, needs follow‑up.

• Drain and refill with manufacturer‑specified coolant
• System pressure test and leak check
• Cap, hose, radiator, and fan inspection with final verification

The manufacturer publishes the schedule for this vehicle, and that guidance determines the change interval.

Between scheduled services, technicians can test coolant condition during routine visits to confirm protection and inhibitor health. Driving in high heat, towing, and frequent short trips may justify more frequent checks. Follow the owner’s information and ask us to test the fluid at your next visit.

• Follow the vehicle’s published maintenance schedule
• Test coolant condition between intervals
• Adjust checks based on climate and usage

The manufacturer specifies the correct coolant for this vehicle, and coolants are not interchangeable.

Colour is not a reliable guide to what’s in the bottle, and mixing types can reduce corrosion protection and service life. We use the type and concentration specified for the 2018 Ford Flex to maintain designed performance and component longevity.

• Use only the specified coolant for this model
• Do not mix types based on colour
• We install the correct coolant and verify protection

Topping off restores level but does not refresh depleted corrosion inhibitors, and a level that keeps dropping indicates a leak.

Only check the system cold; it is pressurized and hot after running. If you need frequent top‑offs, book an inspection to locate and repair the cause. A complete service restores proper protection and verifies there are no leaks.

• Check level only when the engine is cold
• Repeated loss = inspect for leaks
• Service restores protection, not just level
