If your engine is getting too hot, the radiator is the first thing to check. But before you call a garage, you probably want to know how much the whole job will cost. In this guide we break down the price of a new radiator, the labour you’ll pay, and the extra bits that can surprise you.
The price of the radiator itself depends on the make of your car and the quality you choose. A basic replacement for a common hatchback can start around £80‑£120. Mid‑range options for popular Italian models such as Fiat or Alfa Romeo usually sit between £150 and £250. If you drive a high‑performance Ferrari or Lamborghini, the part can climb to £500‑£1,000 or more because it’s a specialised unit.
Don’t forget the ancillary parts. Coolant hoses, clamps and the thermostat are often sold as a kit for £20‑£50. A professional coolant flush, which removes old fluid and debris, typically adds another £30‑£60. If you need a new fan or sensor, factor in an extra £40‑£80.
Labour is the biggest variable after the part itself. A straightforward radiator swap on a rear‑engine car can take about 2‑3 hours, while a front‑engine model with tight engine bays may need 4‑5 hours. In the UK, most garages charge £70‑£90 per hour, so you’re looking at £140‑£450 in labour depending on the complexity.
Some workshops offer a flat‑rate quote that includes both part and labour. This can be handy because you won’t be hit with surprise time‑overrun fees. Always ask if the quote covers disposal of the old radiator – some shops charge a small fee for that.
Now that you have the raw numbers, here’s a quick way to estimate your total cost:
Example: A mid‑range Alfa Romeo radiator (£200) + hoses (£30) + 3 hours labour at £80/hour (£240) + VAT (£94) = roughly £564 total.
If you’re comfortable with tools, a DIY replacement can save the labour cost entirely. You’ll need a lift or jack stands, a socket set, and a drain pan for coolant. The process usually takes 2‑3 hours for a DIYer, but make sure you follow safety steps – disconnect the battery, relieve pressure in the cooling system, and properly bleed the new radiator to avoid air pockets.
When you call a garage, ask for a detailed breakdown. A transparent quote shows part cost, labour time, taxes and any additional items. This makes it easier to compare different shops and avoid over‑charging.
Bottom line: radiator costs can range from under £200 for a basic swap on a small car to over £1,200 for a high‑end sports model with premium parts and labour. Knowing the pieces of the price puzzle helps you get a fair quote, decide whether DIY is right for you, and keep your engine from overheating.
