Coolant Change
What is a coolant change or flush?
A coolant change involves simply draining the coolant at the bottom of the radiator, then topping up the radiator with fresh fluid until it it’s full. Alternatively, the technician can remove the drain plugs on the engine block, which lets all the coolant drain out of the engine and cooling system components, and then top up with new coolant.
A coolant flush is more complex, and usually a bit more expensive. Instead of letting gravity do the work, flushing uses water pressure to blast any accumulated contaminants out of the cooling system’s passageways. Both the radiator and the engine block are cleaned out. The final step is to add new replacement coolant.
