I have been using the Engine Clean twin tube coolant machines for about ten years. The volume during the extraction is very fast. This is very critical if the vehicle is running during the service. This avoids the engine from overheating. I have used it with the vehicle not running also. Doing the service engine off, I have put it in extraction and walk away with no worry of component damage and allows maximum exchange.  The refill or vacuum displacement of coolant is very fast to ensure engine overheating does not occur. The flexibility of doing a small vehicle cooling system all the way up to a 1 ton diesel cooling system has a huge advantage of having multiple machine to perform the same process. This machine never breaks, I never have any issues with these machines going down.Great machine!
