What Can Cause a Radiator to Crack
Here are a few of the main causes of radiator cracks. Read more about each cause below.Temperature Fluctuations RocksAccidentsRadiator FansDirty CoolantOver PressureTemperature Fluctuations
Your radiator has to be able to function anywhere between ambient temperature (which varies depending on where you live) to over 200 degrees! These drastic swings create thermal stress on the metal and plastic in the radiator, which can cause a radiator to crack or leak over time, regardless of how well you care for your vehicle.

Your radiator is at the front of your vehicle protected only by your vehicle’s grill. Rocks and road debris can easily find their way in through the grill and poke holes in your radiator tube and fin matrix. These leaks are often slow and will cause drips at the front of your vehicle. Small leaks like this can easily be fixed using BlueDevil Radiator and Block Sealer.Accidents
Fender benders regularly cause radiator leaks since your radiator is at the front of your vehicle. Anything that pushes on the front of your vehicle has the chance to damage or even split the radiator core support, causing leaks in the radiator or in the coolant hoses that connect to it. If you’ve been in an accident, make sure your frame is straight before attempting to repair your radiator.Radiator Fan
Fans can cause radiator damage in two ways. If your radiator fan doesn’t turn on it can cause high temperatures and pressure in your system, leading to cracks. On the other hand, if your radiator fan is spinning but has a bad bearing, the wobbly fan can contact your radiator damaging the tubes and causing a leak.Dirty Coolant
Dirty coolant can cause a radiator leak due to corrosion. If your coolant is dirty or of the wrong type it can cause pitting in the aluminum radiator or cylinder head. Since your radiator is made of thin metal small pits in the aluminum can lead to leaks. Make sure to regularly flush your radiator to ensure your coolant is not damaging your radiator.

As the antifreeze in your cooling system heats up it will expand and expanding fluids increase pressure in a closed system. Your radiator cap is designed to release pressure at a certain point, usually between 10 and 18 PSI. If your radiator cap is malfunctioning it can cause an overpressure in your system which can damage some of the more delicate components in your radiator. Radiator caps are usually inexpensive so consider replacing yours if you are worried about high pressures in your system.
How Long Can You Drive With a Cracked Radiator?
If you have a cracked radiator, your check engine light may not come on immediately. But if you notice an issue, you should never drive with a cracked radiator. Driving without a working radiator can cause your car to overheat, stop working altogether, or even catch on fire! Driving with a cracked radiator is simply not worth the risk.
Cracked Radiator Cost
The price to fix a cracked radiator will vary greatly depending on the make and model of the vehicle as well as how you choose to get the radiator fixed. If you need a complete replacement and get it repaired at a shop, your costs will be much higher than a simple patch job or attempting to seal a leak with a stop leak solution.
