What a coolant change costs
At roughly 2 to 2.5 gallons of capacity, the coolant itself is about $30 to $75. A shop charges $70 to $120 for a drain and fill, or $100 to $250 for a full flush. Use the specification the manufacturer lists - mixing coolant chemistries is what turns a cheap service into a water-pump job.
