Buying options by source
Where you buy can noticeably affect the price, shipping, and availability. Here are typical ranges by source as of 2024–2026.
- Honda dealership parts counter: roughly 40–60 USD for a new thermostat, with higher prices if taxes or fees apply

- Online retailers (RockAuto, Amazon, e-commerce marketplaces): often 10–40 USD, plus shipping
- Used or salvage yards: typically 5–15 USD, depending on condition and availability
- Local independent shops or mechanic supply shops: prices vary, but parts are often available within the 15–50 USD range depending on OEM vs aftermarket
Shopping across these channels can yield noticeable savings, especially if you don’t need an OEM part and you’re comfortable with aftermarket equivalents or a used unit.
DIY replacement considerations
Replacing the thermostat yourself can save labor costs, but it requires basic tools and attention to coolant handling. The following steps outline a typical replacement process.
To perform the replacement, you’ll typically need standard hand tools, a coolant drain pan, new coolant, and a new gasket or gasket sealant as required by the part you buy.
- Ensure the engine is completely cool and disconnect the negative battery terminal for safety.
- Drain some coolant from the reservoir or radiator to minimize spills.
- Locate the thermostat housing on the engine block and identify the mounting bolts and hose clamps.
- Carefully loosen and remove the hose clamps and detach the upper radiator hose from the housing.
- Remove the thermostat housing bolts and lift off the housing to access the thermostat.
- Take note of the thermostat’s orientation before removing it. Clean the housing surface thoroughly to remove old gasket material.
- Install the new thermostat in the correct orientation, then reattach the housing with a new gasket or sealant as specified by the part you purchased.
- Reconnect the hose, tighten bolts to manufacturer specs, and refill the cooling system with the correct mixture of coolant.
- Start the engine and clinically bleed any air from the cooling system, checking for leaks and monitoring the coolant level after warm-up.
- Dispose of old coolant properly and reset the system as needed.
If you’re not comfortable with DIY work or if you don’t have the right tools, consider hiring a mechanic. A professional can typically complete the job in a couple of hours, and the total cost will include parts plus labor.
Summary
The thermostat replacement for a 2003 Honda Element generally costs between 15 and 60 USD for the part itself, with OEM parts at the higher end and aftermarket parts typically cheaper. Total costs can increase with labor if you opt for professional installation. Shop around across dealerships, auto parts stores, and online retailers to compare prices and ensure you get the correct part for your engine variant. If you’re comfortable with basic tool use and coolant handling, a DIY replacement can save on labor while giving you a straightforward path to getting your Element back on the road.
