We sell BG services at work and I must say I’m pretty impressed with most of them. Coolant flush should be done every 5 years with Dexcool and 3 years with the glycol. Transmission service between 40,000 and 60,000 miles depending on the vehicle, this is a great service, unlike the conventional drop the pan and change 1/4 of the fluid in the transmission, the BG flush does it when the vehicle is running, there’s a tank with 2 sections with a bladder in the middle, new fluid is put in the machine and sits on the top portion, 1 hose hooked up to a cooler line, other hose to the radiator where the fluid enters the cooler. As it’s running the oil pump in the transmission pushes the old fluid out into the bottom portion of the tank which pushes the bladder up to put the new fluid sitting on top into the transmission. We run 12 liters through so it changes ALL of the fluid in the transmission, lines and cooler(s). Great service IMO.
The Fuel/air induction service is a pressurized tank with around 25oz of cleaner in it that sprays in the throttle body while the engine is running. Takes about 10 minutes to run through. Cleans all the carbon out everywhere the air goes into the whole engine. After it’s done you rev the engine up and there’s a big cloud of white smoke as it clears everything out. I’ve noticed a noticible difference in power in a lot of cars I’ve done this service to. There’s also 12oz of cleaner that goes in fuel tank to clean the fuel system, injectors etc.
Power steering flush is also done while the engine is running, sucking old fluid out as new fluid is being put in, turning the wheel lock to lock mid way through to get all the old stuff flushed out. We’ve only done a couple of the engine oil flush, that’s the only one I’m skeptical of.
RacerX22 you wouldn’t have to worry about the power steering flush because your car has electric power steering, as well as the transmission flush since it’s done on automatic transmissions and not manuals. It is a good idea to change your transmission fluid at the same intervals as the automatics though.
