You can buy coolant (also known as antifreeze) at a wide variety of places, from dedicated auto parts stores to major online retailers and even your local supermarket. The most common and reliable locations are auto parts stores like AutoZone, Advance Auto Parts, and O'Reilly Auto Parts, where you can also get expert advice. Other options include big-box stores (Walmart, Target), wholesale clubs (Costco, Sam's Club), and online marketplaces like Amazon.
Before you buy, it's critical to know the correct type for your vehicle. Using the wrong coolant can lead to serious engine damage. Check your owner's manual for the manufacturer's specification. You'll often see types like OAT (Organic Acid Technology), common in modern General Motors vehicles, or HOAT (Hybrid Organic Acid Technology), used by many Ford, Chrysler, and European brands.
Here’s a quick comparison of where to buy:
| Retailer Type | Examples | Price Range (per gallon) | Key Advantage |
|---|
| Auto Parts Stores | AutoZone, O'Reilly | $20 - $30 | Expert staff, store brand options, loaner tools |
| Department Stores | Walmart, Target | $15 - $25 | Low cost, convenient for general shopping |
| Online Retailers | Amazon, RockAuto | $15 - $35 | Widest selection, home delivery, user reviews |
| Wholesale Clubs | Costco, Sam's Club | Varies (multi-pack) | Bulk pricing for members |
| Service Stations | Dealership, Jiffy Lube | $25 - $40+ | Guaranteed OEM compatibility, professional installation |
For most DIYers, an auto parts store is the best bet. The staff can often look up your car's specific needs using your license plate or VIN. If you're in a pinch, many gas stations or convenience stores sell small, pre-mixed bottles for emergency top-offs. Remember, coolant is typically sold as either concentrate (which you mix 50/50 with distilled water) or as a pre-mixed 50/50 solution that's ready to use. Always handle coolant carefully and dispose of old coolant properly at a designated recycling center.
