Your radiator keeps your engine at a safe operating temperature by dispersing heat and circulating coolant effectively. If it fails, the most likely symptom you’ll notice is an overheating engine or smoke/steam billowing from the bonnet. This may be accompanied by the temperature warning light on your dashboard.

If your car is struggling to keep itself cool, it’s very likely that you won’t be able to drive it anywhere, creating an incredibly stressful situation.

If you’ve noticed low coolant levels, a brightly coloured leak under the car or suffered a breakdown due to overheating, you need to get the problem fixed quickly.

 

When Should I Book a Radiator Repair?

If you’ve noticed any of the following, it’s time to book a radiator repair near you:

  • Low coolant levels

  • A brightly coloured leak under the car

  • Rust or visible damage on the radiator when you inspect the engine bay

 

Likewise, any issues with overheating suggest a problem with your car’s radiator so you should book a repair as soon as you notice smoke/steam coming from under the bonnet.

 

What if My Radiator Isn’t to Blame?

A car’s cooling system is quite complex, and a failing radiator may not be your main problem.

A coolant leak, inefficient or low-quality coolant and problems moving coolant around the system can all cause your radiator to fail by placing it under more strain.

If you notice a brightly coloured puddle under your car (usually green, pink or orange) or low coolant levels within the reservoir, there’s likely a leak somewhere in the system which needs fixing.

Likewise, if your coolant isn’t as brightly coloured as it should be or there are bits floating in it, you should book a coolant change as soon as possible.

Frequently asked questions

We’re working hard to add radiator repairs to our list of instant price products. In the meantime, you can compare labour rates from local garages to see how much a lengthy repair is likely to cost.
A garage’s labour rate is how much they charge for an hour of their time. It accounts for their level of experience, any specialist equipment and/or facilities they have access to as well as their general overheads, and is usually competitively priced against other garages in the area.
You may be able to perform a temporary radiator repair, such as using sealant to fix a small leak or tightening a loose hose, but anything more advanced will require a professional repair.

We strongly advise against repairing your radiator if you don't have any mechanical experience because you can cause serious long-term damage and put your safety at risk with a sub-standard radiator repair.
You should only add water to your car’s radiator as an emergency, short-term solution.

Circulating tap or distilled water is better than no fluid at all, but it’s not a long-term alternative to engine coolant.

Once you’ve got your car home or to a local garage, you should look to replace the water in your system with the correct coolant for your engine to maximise its protection.
We show verified, unfiltered reviews from genuine customers for every garage on our comparison site. These detail real experiences from drivers just like yourself – so when you choose a highly rated local garage with dozens of 5* reviews, you can be sure they’ll provide a great experience.

If they’ve also been rewarded with a Silver, Gold or Top Tier badge – highlighting them as one of the very best garages near you – you can have even more confidence in your decision.
Many garages on our platform offer Payment Assist or Klarna monthly repayment options to help spread the cost of an expensive repair.

Unfortunately, we’re currently unable to show which garages offer these services. Some may display it on their listings with custom banners, but you may need to contact your preferred garage directly if this is something you need.
Yes, we have a growing network of mobile mechanics on our platform, many of whom offer mobile radiator repairs. This helps make your life easier, especially if your car is undriveable.

To book a mobile radiator repair, select ‘Only Mobile Mechanics’ from the left-hand sidebar. This will filter out static garages from the results, only showing options that meet your needs.
Every garage on our platform sets and updates their own prices, so what you see is always what you’ll pay. The only reason the cost will change is if you agree to additional work with them directly or require a different repair.
Yes, you should repair your radiator as soon as possible because it’s a vital car part. Without a functioning radiator, your engine will likely run too hot, potentially causing serious damage to the cylinders and/or engine block.

It can also lead to repeated breakdowns and potential MOT failures, which all incur additional stress and costs.
The average UK car radiator repair costs around £200, with prices ranging from £150 to £400. The price will vary depending on your vehicle and the extent of the problem.

Your chosen garage will be able to provide an accurate quote once they have inspected the damage.
A car radiator repair usually takes between 1 and 2.5 hours, depending on your vehicle and the severity of your repair.

The average repair usually takes around 1.5 hours, but your chosen garage will be able to give you a more accurate estimate after inspecting your car.
Yes, a car under warranty is covered for any radiator repairs that arise from a mechanical fault. However, we would recommend checking the terms and conditions of your warranty before making a claim to ensure you're covered.
Due to the extreme weather conditions we often experience in the UK, it is unsafe to use solely water in your car radiator.

During colder periods water can freeze once the temperature reaches 0°C, and expand into ice crystals within the reservoir.

In the warmer months, water can turn into steam as a result of high pressure within the engine.

As you can imagine, water can cause real damage in either circumstance. 

When it is time to replenish coolant levels, there are two ways to do so.

You can buy engine coolant as a pre-mixed solution, which is usually made up of a 50:50 ratio of distilled water to antifreeze.

Alternatively, you can mix a 50:50 ratio of distilled water to antifreeze yourself, so that the antifreeze can regulate the boiling point of the liquid. 

If you choose to take the latter approach, you should bear in mind that the water you use should always be bottled or distilled.

Tap water contains minerals which can cause damage to the engine, and may even clog or corrode the radiator pipes. 

Topping up with water can help you drive to the nearest garage - as long as you keep an eye on the temperature gauge or warning lamp.
