Coolant exchange vs. drain and fill?
Again, when you simply drain and fill the cooling system, you are only draining what’s in the radiator, which is not even half of the system. With a coolant exchange, our machine drains the entire cooling system, performs a leak and pressure test of the cooling systems hoses, gaskets and clamps and then completely fills the cooling system to its proper level and mixture. Coolant or “antifreeze” wears down and loses its effectiveness to properly protect the metals in your engine. Another valuable service.
