What the job involves
A coolant change drains the old antifreeze, optionally flushes the system, and refills with the coolant type your engine requires, then bleeds out air pockets.
Warning signs
- The interval in your owner's manual has arrived (often 100,000 miles or more for long-life coolant)
- Coolant looks rusty, muddy or has debris
- After a repair that drained the system
What changes the price
- Your vehicle. Parts for trucks, European and luxury models usually cost more, and on some engines the mechanic has to remove other parts first, which adds labor hours.
- Where you go. Dealers often charge 25% or more above independent shops. Most shops bill about $120 to $159 an hour (AAA, citing a 2025 PartsTech survey).
- The parts. OEM (factory) parts cost more than aftermarket or remanufactured parts. Ask which ones the estimate uses and what warranty comes with them.
- Extras. Related parts found during the job, fluids, shop supply fees and sales tax are not included in these averages.
How to pay less
- Use the coolant type in your owner's manual; mixing types can cause problems.
- Have it done together with a water pump, thermostat or radiator replacement.
How to get a fair estimate
- Ask for a written estimate that lists parts, labor hours and the shop’s hourly rate before any work starts.
- Ask whether the quote uses OEM, aftermarket or remanufactured parts, and what warranty comes with the parts and the labor.
- Get a second quote for any repair over a few hundred dollars. Independent shops often charge less per hour than dealers.
- Ask the shop to show you the old part or the reading that proves it failed, and to call you before doing extra work.
- Check for recalls and warranty coverage first: many powertrain, emissions and hybrid parts carry longer factory warranties.
