Simple Ways to Save at The Radiator Warehouse

You don't have to be a pro mechanic to save money on your radiator or heater core. The Radiator Warehouse has a few simple programs anyone can use. The easiest way is to look for a promo code before you check out. You can often find these on coupon websites. Another simple method is to check if your part qualifies for their core charge refund. When you buy a new radiator, you can send your old one back for a refund, which lowers your final cost.

Best Times to Shop

While their everyday prices are competitive, you can find even better deals during specific times. Keep an eye out around major holidays like Memorial Day, Fourth of July, and Labor Day, as they often run site-wide sales. It's also a good idea to check for end-of-season promotions, especially as summer winds down, which can be a great time to buy cooling system parts.

Using Their Rewards Program

The Radiator Warehouse has a straightforward loyalty program called Radiator Rewards. Here’s how to make the most of it:
