What to ask for

Use terms like radiator fan relay , cooling fan relay , or engine cooling fan relay when searching, since stores may label the part differently. If you want the exact OEM match, check the part number against your VIN or the relay in your fuse box before buying.

Practical tip

A lot of stores let you enter your vehicle first, then filter by cooling- system electrical parts, which is the fastest way to avoid buying the wrong relay. If you’re replacing it yourself, the relay location is typically in the engine compartment fuse block, and some guides suggest testing it with a multimeter before swapping parts.

Pricing

Prices vary by seller, but one listing shows an AC Delco relay at $16.97 on PartsGeek, while repair estimates for replacement can be much higher if you pay for labor.

TL;DR: Start with O’Reilly, AutoZone, Advance, or NAPA for the quickest buy-and-pickup options, and use GM/OEM sellers if you want the exact factory- style relay.
