The below maintenance schedule is cropped at 36 months / 60000 km for ease of reading. Mixing standard “green” formula coolant with a long-life OAT or HOAT coolant may reduce the service life of the mixture to two to three years, or 30,000 to 50,000 miles. Follow the earlier of the time or distance service interval in the below schedule. Intermixing different types of antifreeze may void any remaining warranty coverage on the cooling system components, and may even create some undesirable chemical interactions that reduce the coolant’s ability to inhibit corrosion. It doesn’t have to be the exact same brand, but the coolant must meet the OEM specifications (Dexcool, for example, in the case of GM applications). If a vehicle still is under warranty, it should be refilled with the same type of coolant as the original factory fill. Antifreeze can break down over time, especially IAT and some hybrid OAT solutions where the additives drop out and, therefore, dont provide enough corrosion. The end result is an almost complete coolant change.
The machine taps into the plumbing and extracts the old coolant while replacing it with new.
IT HAS A LONGER MAINTENANCE INTERVAL COMPARED TO LONG LIFE COOLANT LLC. Toyota Genuine Super Long Life Coolant requires changing for the first time only after the vehicle has travelled 160,000 kilometres - or 150,000km for Avalon and Camry. The best way to change coolant is to have it professionally changed with a coolant exchange machine. SLLC ABSORBS ENGINE HEAT AND RELEASES IT THROUGH THE RADIATOR. Minivans and SUVs with rear heater circuits can trap even more residual coolant in their veins. The other third remains trapped in the engine block, heater core and heater hoses. Draining the radiator to change the coolant only removes about two-thirds of the total coolant in the system.
