A proper coolant flush runs $100 to $200 at an independent shop. A drain-and-fill (which is what most cars actually need) is closer to $70 to $120. Skip the dealer "$300 cooling system service" unless the system is contaminated.
Most drivers pay $120 to $160 for a full coolant flush at an independent shop.
OEM long-life coolant (Toyota pink, GM Dex-Cool, BMW blue) costs more.
Trucks and V8 engines hold 12-16 quarts vs 6-8 for compacts.
A machine flush adds $40-$80 over a simple drain-and-fill.
Often done at the same time if the coolant is old.
A failing hose discovered during the service drives up the total.
Dealerships charge 50-100% more than independent shops.

Conventional green coolant: every 30,000 miles. Long-life OEM coolant (Toyota pink, Dex-Cool, BMW blue): every 5 years or 100,000-150,000 miles per the owner manual.
Drain-and-fill removes about 50-60% of the old coolant. A full flush uses pressure to push out trapped fluid in the heater core and block, removing 90%+.
For routine maintenance with clean coolant, drain-and-fill is enough and saves money. Do a full flush if the coolant is brown, contaminated, or after a head gasket repair.
No - chemistries (IAT, OAT, HOAT) are not compatible and can gel. Stick to what your manual specifies, or universal coolant rated for your vehicle type.
Only if the cause is degraded coolant. Most overheating is a failing thermostat, water pump, radiator, or fan - the coolant is innocent.
For a neglected system, a chemical flush can help dissolve rust and scale. Skip it on a clean, well-maintained system.
