AutoZone carries hundreds of thousands of parts and accessories.

When your GMC S15 radiator cap goes bad, it spells trouble. This important part does more than keep your radiator fluid in. It also monitors pressure to prevent overheating. If the cap is broken or worn-out, it must be replaced – before trouble occurs.

We're sorry, but there are no results in this parts category for GMC S15. Please select another vehicle or click on the Parts tab at the top of the page to see the available parts for this vehicle.

If you need a new radiator cap, it isn't a big deal to change it. All you need is to stop into AutoZone for your choice in S15 radiator caps. To switch it out, just screw off the old one and screw on the new one. The cap is located on the radiator near the front under the hood. You have the option of shopping online with us, too. If you order online, you have the choice of Same Day Store Pickup or Free Shipping on $75 or more.
