Please recommend the best method for flushing the 348TS.
Jack car up and remove under trays Unscrew the system radiator cap Unscrew drains under the radiators on both sides. Unscrew one of the block drain (you will get a shower of poison coolant) Now clean up the floor and yourself so you don't slide around or fall on your arse Put back the radiator drains and block drain plugs. Put back undertray and lower car refill with 1:1 coolant and distilled water until it is full. Turn engine over with heater on full blast, and let car warm up to operating temp. There are 2 bleed screws on the right side of the car, toward the front of the engine compartment. You need to loosen those and wait for the air to come out until there is no air. Tighten bleed screws and you are done. Turn off engine.
