Thinking about a new radiator but worried about the price? You’re not alone. A faulty radiator can overheat your engine fast, and the right replacement keeps your car running smooth. In this guide we break down the real cost of a radiator when it’s installed, so you know exactly what to expect before you sign off on the work.
First up, the type of radiator matters. Basic steel models are the cheapest, usually £80‑£150 for the part alone. Aluminium or high‑performance units for sportier cars can jump to £200‑£400. Then there’s the make and model of your vehicle – a common family hatchback will be cheaper than a luxury SUV because parts are more widely stocked.
Labor is the next big chunk. A professional shop typically charges £70‑£120 per hour, and most jobs take about 1.5‑2 hours. That means labour can add £100‑£200 to your bill. Some garages include the part price in a flat‑rate quote, which can simplify things, but always ask for a breakdown.
Location also plays a role. Shops in city centers or affluent areas often have higher overheads, so you might see a £20‑£40 premium compared to a workshop on the outskirts. Finally, extra services like coolant flushing, pressure testing, or replacing related hoses can push the total up by another £30‑£80.
One easy way to cut costs is to shop around for the part yourself. Online retailers and local auto parts stores often sell radiators for 10‑20% less than a garage’s markup. Bring the part price to a reputable garage – many will match the cost or at least give you a discount for supplying it.
Consider timing. Shops sometimes lower labour rates during slower periods, like mid‑winter or early autumn. Booking an appointment in advance rather than walking in for an emergency can also net you a better price.
If you’re comfortable with tools, a DIY install can save the labour charge entirely. The job isn’t extremely complex: drain the coolant, remove the old unit, bolt in the new one, refill and bleed the system. Plenty of video tutorials walk you through each step. Just make sure you have the right bolts and a proper coolant flush to avoid future leaks.
Don’t forget to check for any warranties. Many new radiators come with a 12‑month guarantee, and some garages offer free removal of the old unit. A warranty can save you money if the new radiator fails early.
In short, expect a total installed cost of £180‑£450 for a typical family car, with luxury models edging closer to £600. By comparing part prices, timing your visit, and asking about bundled services, you can keep the expense on the lower end of that range.
