Who makes thermostats for Napa?

NAPA Auto Parts sources thermostats from multiple manufacturers, including its private-label Duralast line and established aftermarket brands such as Stant and Gates. The exact supplier depends on the part number and the vehicle application.


This article examines where Napa sources its thermostats, which brands are commonly seen in its catalog, and how shoppers can determine the right thermostat for their vehicle. We’ll look at the mix of private-label versus name-brand options and offer practical tips for choosing a compatible part.


Where the thermostats come from


Thermostats in Napa’s lineup come from a blend of private-label and widely used aftermarket manufacturers. The Duralast line provides cost-effective options under Napa’s own brand, while Stant and Gates thermostats appear as common non-OEM choices across many vehicles. In some cases, OEM-style parts from the vehicle manufacturer (such as Ford Motorcraft or GM ACDelco) may be available if stocked by Napa.


Note that availability varies by store location and online stock. Checking the Napa website or asking a store associate can help confirm the exact brands and part numbers for a given vehicle.



  • Duralast thermostats (NAPA’s private-label line)

  • Stant thermostats (a leading aftermarket thermostat manufacturer)

  • Gates thermostats (a major supplier of automotive components)

  • OEM-style options from vehicle manufacturers (e.g., Ford Motorcraft, GM ACDelco) when stocked


The brands listed above represent the typical sources you’re likely to encounter in Napa’s catalog. The actual brand you receive depends on the part number and the vehicle’s make, model, and engine configuration.


How to choose the right thermostat


When selecting a thermostat, consider the vehicle’s cooling system specifications, the desired temperature rating, warranty terms, and price. The Duralast option often provides a value choice, while Stant or Gates offerings may be preferred for their established performance track records. Always verify compatibility using the vehicle’s year, make, model, and engine code.


Napa’s product pages and in-store staff can help cross-check part numbers and ensure you’re getting the correct fit for your vehicle.


What customers should know


Thermostats are not universally interchangeable between engines. Small differences in temperature ratings, housing design, or fit can affect cooling performance. Availability can change as new applications enter the market, so it’s important to confirm the exact part number and brand for your particular vehicle.


Summary


In short, Napa sources thermostats from multiple manufacturers, with Duralast as the private-label option and Stant and Gates as prominent aftermarket suppliers. Availability varies by store and vehicle, so checking the specific part number and using Napa’s lookup tools or staff guidance is the best approach to ensure the correct thermostat for your vehicle.
