How much to replace a radiator in a Honda Odyssey?

A typical radiator replacement for a Honda Odyssey costs about $500 to $1,200 in total, depending on parts quality and labor. The exact price hinges on whether you choose aftermarket versus OEM parts, local labor rates, and whether any related cooling-system components need replacement.

In this article, we break down the main cost drivers, provide typical price ranges for both parts and labor, and offer practical tips for getting accurate quotes. The Honda Odyssey’s cooling system is essential to engine performance, and a radiator replacement involves removing the old unit, installing the new one, refilling coolant, and testing for leaks. Additional work—such as replacing hoses, the thermostat, or a cooling-fan assembly—can raise the final cost.

Cost drivers and regional variation

Several factors influence the final bill, including the choice between OEM (Honda) and aftermarket radiators, regional labor rates, and whether the repair requires related cooling-system components.

OEM vs aftermarket choices

OEM radiators from Honda are designed to fit your exact Odyssey model but tend to be pricier. Aftermarket radiators can save money, but quality and warranty levels vary by brand. When choosing, balance price with reliability and the dealership or shop’s warranty policy.

These estimates reflect typical price ranges for components involved in a radiator replacement. Actual prices vary by model year, vendor, and location.

• Radiator (aftermarket or generic): 100–260 USD


• Radiator (OEM/dealer): 180–450 USD


• Coolant (pre-mixed): 15–40 USD


• Thermostat: 15–40 USD


• Hoses and clamps: 5–60 USD


• Radiator cap: 5–20 USD

These component costs cover the core parts. If you need additional items such as a radiator fan, shroud, or a coolant flush, expect higher totals.

Labor costs and time

Labor charges are driven by the job’s complexity and the shop’s hourly rate. For a Honda Odyssey, the radiator replacement typically requires moderate access and can take several hours, with prices varying by region.

• Typical time to complete: 2–4 hours


• Common shop labor rate: 75–150 USD per hour


• Estimated labor charge range: 150–600 USD

In practice, the total labor portion often lands in the mid-range of the overall bill, with dealer or specialty shops sometimes charging more for diagnostics or guaranteed labor warranties.

Saving money and getting quotes

To keep costs reasonable, follow a structured quoting process and consider your parts options.

• Get written estimates from at least three shops, including both independent mechanics and dealers.


• Ask for a detailed, itemized quote that separates parts, hoses, coolant, and labor.


• Compare OEM versus aftermarket radiator prices, but check warranties and return policies.


• Ask about bundled services, such as a coolant flush or hose replacement, and whether labor coverage is included.


• Check if your vehicle is still under any extended warranty or recall coverage that might apply to cooling-system components.

Armed with multiple, itemized quotes, you can choose a option that balances cost, quality, and warranty protection.

Summary

For a Honda Odyssey, expect a radiator replacement to cost roughly $500 to $1,200 in total, depending on part choice (OEM vs aftermarket) and labor rates in your area. OEM parts tend to push the price higher, while aftermarket parts can offer savings with varying warranty terms. Always obtain multiple, itemized quotes and consider the overall value, including potential savings from a bundled coolant flush or parts replacement if needed. A well-chosen radiator replacement should restore cooling performance and reliability without surprise costs.
