NOTE: Inspect the supercharger oil every 30,000 miles (48,000 km). Toyota does not have an interval to drain and refill the system. If necessary, remove the magnetic plug under the rear cover and drain the oil. Insert the plug with gasket and using a syringe and vinyl tube, fill the system with supercharger oil.
The correct coolant is any permanent, high quality ethylene glycol antifreeze mixed in a 50/50 concentration with water. This mixture gives the best combination of antifreeze and anti-boil characteristics within the engine.
