How Much Does a Radiator Cost for a 2006 Honda Civic?

Expect to pay about $90–$220 for an aftermarket radiator and $300–$500 for an OEM Honda unit (parts only) for a 2006 Honda Civic. Installed at a shop, the total typically runs $350–$850, depending on labor rates, trim (regular 1.8L vs. Si 2.0L), and whether related parts and fluids are replaced at the same time.

What Drives the Price

The cost varies with the type of radiator you choose, your Civic’s exact trim, and the shop’s labor rate. Here’s how those factors usually break down in the U.S. market as of 2025.

• Aftermarket radiator (non-Si 1.8L): typically $90–$220
• Aftermarket radiator (Si 2.0L): typically $140–$260
• OEM Honda radiator assembly: roughly $300–$500
• Labor: 1.5–2.5 hours at about $100–$180/hour ($150–$450)
• Coolant (Honda Type 2): $25–$45
• Shop supplies/disposal fees: $5–$25

On balance, most owners see a total installed price in the mid-$400s to mid-$700s, with dealer quotes often at the higher end.

Aftermarket vs. OEM: Which to Choose?

Both options can be appropriate, but they differ in price, availability, and warranty coverage. Consider the trade-offs below to match your budget and priorities.

• Aftermarket: Widely available (e.g., from major parts retailers), lower cost, multiple brands; quality varies by manufacturer.
• OEM Honda: Higher price, generally consistent fit/finish; good choice if you prefer factory parts or your vehicle is stock and you want original performance.
• Si models: Often use different radiators than non-Si trims; expect slightly higher parts prices and confirm fitment by engine (2.0L) and transmission.

If you’re cost-conscious and your Civic isn’t modified, a reputable aftermarket brand usually balances price and reliability; OEM is a solid pick if you value factory specifications and long-term fit confidence.

Total Installed Cost Scenarios

Depending on where you get the work done and whether related components need attention, your total bill can vary. These common scenarios illustrate typical ranges.

• Independent shop, aftermarket radiator, basic install: $350–$650
• Independent shop, OEM radiator, basic install: $500–$800
• Honda dealer, OEM radiator: $600–$1,000
• DIY (aftermarket): $120–$300 for parts/fluids, plus your time and tools

DIY can save substantially if you’re comfortable with draining coolant, removing fans and hoses, and bleeding the system, but many owners prefer a shop for speed and warranty coverage.

Common Add-Ons That Affect Price

Shops may recommend replacing wear items while the system is open. These are sensible to do if parts are aged or leaking, but they add to the total.

• Upper/lower radiator hoses: $30–$70 for the pair
• Thermostat and gasket: $25–$60
• Radiator cap: $10–$20
• Automatic-transmission fluid top-off (if applicable): $5–$20
• Cooling fan assembly (if noisy or cracked): $120–$250

Approving these items can push a mid-range job toward the upper end, but it can prevent repeat labor and future overheating issues.

How to Get an Accurate Quote

Because trim and transmission can change fitment and labor, a targeted quote ensures you’re comparing like-for-like across shops and parts suppliers.

• Provide your VIN, engine (1.8L or 2.0L Si), and transmission (manual or automatic).
• Ask for separate line items: radiator brand/part number, coolant, labor hours, and any recommended hoses/thermostat.
• Request pricing for both aftermarket and OEM to compare.
• Confirm warranty terms on parts and labor.

With those details, you can quickly identify the best value and avoid surprises at checkout.

Bottom Line

For a 2006 Honda Civic, plan on $90–$220 for a quality aftermarket radiator or $300–$500 for OEM, with installed totals typically $350–$850 at a shop. Prices trend higher for Si models and dealer service, and additional cooling-system parts can raise the final bill.

Summary

A replacement radiator for a 2006 Honda Civic generally costs $90–$220 (aftermarket) or $300–$500 (OEM) for the part alone. Including labor, coolant, and fees, most drivers pay $350–$850, with variations by trim, shop rates, and whether hoses, thermostat, or other items are replaced concurrently.
