Left unchecked, a leaking car radiator could cause serious damage to your engine, forcing you to pay out for expensive repairs. Find out how much car radiator repair costs, and how much money you could save by using K-Seal.
The cost of flushing a car radiator will vary depending on whether you do it yourself or employ a mechanic to do the job professionally.
If you choose to flush it yourself, you’ll be able to keep costs down and just pay for the new coolant, which should be around £40. If you go to a mechanic, the cost of the will be around £70 depending on your car make and model.
Replacing a car radiator, however, can set you back over £250-£700. Labour costs involve a mechanic checking for leaks, removing the radiator, a whole system flush and the installation of a new radiator.
With costs this high it may be tempting to ignore the leak while the car is still functioning. But this can have dangerous consequences.
Your car radiator’s primary function is to keep your engine cool, preventing it from overheating. And that means something as “harmless” as a small radiator leak can develop into a serious issue if left untreated.
Problems which can occur from an ignored radiator leak include:
The heat and pressure of an overheating engine can also cause the engine block to crack or even melt.
A cracked engine block is an expensive repair that has no quick fix. If an untreated car radiator leak is left to cause this type of damage, you could be over £2,000 out of pocket and off the road for some time.
If it’s not treated quickly, a radiator leak can also lead to a blown head gasket.
A blown gasket will allow coolant to enter the car’s cylinders. This will soon lead to severe engine damage, as it prevents the engine from lubricating properly.
With coolant leaking out of the radiator, there will be restrictions on your vehicle’s ability to regulate its temperature causing the engine and radiator to overheat.
An overheated engine will cause the car to become difficult to drive – you’ll experience notable power drops, which could be a big problem on busy roads and highways.
The costs of repairing an overheated engine caused by ignoring a radiator leak vary from relatively cheap ‘quick-fixes’, to eye-watering engine replacements.
Minor repairs triggered by the side effect of a coolant leak will cost less. Heater hose replacement, thermostat replacement and cooling fan wiring repairs will on average come to £75 or less.
Major repairs and extensive engine work will cost more. Water pump replacement, changing the heater core, car radiator and head gasket replacements can range from £350 – £1,250.
A badly overheated cylinder will need to be pressure tested and inspected for warping and engine block crack/melt. These issues can lead to a complete engine rebuild and cost several £1,000 to fix.
Ignoring a radiator leak will lead to a costly outcome which can put you and your vehicle at risk. Stay on top of leaks by looking out for common radiator leak symptoms, such as:
