Fitment guide

Part Catalog & Fitment Finder

Match by vehicle or cross-reference an OE / competitor part number. This Dorman page is arranged as a practical catalog tool because cooling-system sourcing is often decided by application details, interchange confidence and the ability to explain the result to a buyer or technician.

Search by vehicle

Select the vehicle path first when the request comes from a repair order, fleet list or customer inquiry without a confirmed part number.

Cross-reference a number

Use an OE, competitor or superseded number when the buyer needs to confirm whether a cooling-system replacement path is still suitable.

Step 1Select Vehicle (Year-Make-Model-Engine)

Step 2Match or Cross-Reference (OE / competitor part no.)

Step 3Verify Fitment & Find Dealer

Example interchange review
