A thermostat replacement for a 2002 Cadillac DeVille typically costs between $8 and $60 for the part, with labor as an extra if you hire a mechanic.
Prices vary by brand, kit contents, and where you buy. This article explains typical price ranges, buying options, and what affects the final bill to help you estimate the total cost for parts and installation.
Pricing options
Prices depend on whether you choose an aftermarket or OEM thermostat, and whether you buy a standalone unit or a complete kit with gaskets and seals. Here’s a snapshot of current ranges.
- Aftermarket/non-OEM thermostat: typically $8–$20, with some premium aftermarket models in the $25–$30 range.
- OEM GM/Delco thermostat: typically $25–$40.
- Thermostat kit (thermostat plus gasket or housing seal): $15–$45 depending on brand and contents.
- Labor for replacement (if not doing it yourself): $60–$150, depending on shop rates and region.
Part and labor costs can vary, so your total may fall outside these ranges based on local prices and whether there are additional cooling-system services needed.
Where to buy and how to shop
Where you purchase the part can affect price, warranty, and return options. Common sources include:
- Auto parts chains (AutoZone, Advance Auto Parts, O'Reilly): usually align with standard part pricing, often offering in-store pickup and warranties.
- GM dealership or authorized OEM supplier: typically higher for OEM parts but ensures exact cross-reference compatibility.
- Online retailers and marketplaces (Amazon, RockAuto, eBay): wide price range; check shipping and compatibility details.
- Salvage yards or used-parts shops: potentially cheaper but reliability varies; verify that the thermostat is unused or tested.
When shopping, confirm the thermostat’s temperature rating (often 180F or 195F) and your DeVille's engine variant to ensure a proper fit. Some kits include a new gasket or hose seals, which can save additional trips to the parts store.
Compatibility and installation notes
Most 2002 DeVille models with the Northstar engine use a standard thermostat, but mounting details and temperature ratings can vary. Always cross-reference part numbers or VIN-based compatibility before purchase, and follow proper coolant handling and installation procedures if you do the work yourself.
Summary
Thermostat prices for a 2002 Cadillac DeVille typically range from about $8 to $60 for the part, with labor adding roughly $60–$150 if you hire a shop. Total cost depends on whether you choose aftermarket or OEM, whether you buy a kit, and where you shop. By comparing options and ensuring compatibility, you can get a reliable part at a fair price.
