2017 Volkswagen Tiguan Coolant in Tucson, AZ

These symptoms can point to depleted coolant or a leak, and a pressure test helps separate those conditions. The cooling system is under pressure and hot after running, so it should be checked cold rather than opened immediately after driving. Book an inspection if a warning sign appears.

• Temperature gauge running higher than usual
• Sweet smell or a puddle under the front
• Rusty, cloudy or low coolant

The refill uses the coolant type and concentration the manufacturer specifies for this vehicle. Pressure testing helps identify a leak that a fluid replacement alone would not address. The inspection evaluates the parts that help the system contain and circulate coolant.

• Drain and refill with manufacturer-specified coolant
• Cooling-system pressure test
• Inspection of hoses, cap, radiator and water pump area

Coolant condition can also be tested at a service visit between scheduled points, especially if the temperature gauge changes or the fluid appears abnormal. The condition found during testing determines whether the vehicle needs a drain and refill or whether a leak requires repair. This approach avoids judging coolant solely by its appearance.

• Follow the manufacturer's maintenance schedule
• Test coolant condition during a service visit
• Investigate warning signs between scheduled points

Coolants are not interchangeable, so choosing fluid by convenience can compromise the protection the system needs. Colour is not a reliable guide to what is in the bottle or whether it is appropriate. A service visit uses the vehicle's manufacturer requirements rather than colour as the deciding factor.

• Use the manufacturer-specified coolant
• Do not assume different coolants are interchangeable
• Do not use colour alone to identify coolant

The cooling system is under pressure and hot after running, so checking it should be done cold. A pressure test can help identify whether fluid is escaping from the system, while coolant testing helps evaluate its condition. Repeatedly adding fluid is not a substitute for finding the cause.

• Check the system only when it is cold
• Restoring level does not restore depleted additives
• Have a dropping level inspected for leaks
