Cracking Radiators – Causes & Prevention

Cracking Radiators

Radiators are essential components of your vehicle’s cooling system, and when they crack, it can disrupt the entire system. If your radiator cracks, it can cause serious damage to other parts of the car. So, it’s important to understand what causes radiator cracking and how to prevent it from occurring in the first place.

Common Causes of Radiator Cracking

There are several factors that can lead to a cracked radiator. Let’s take a look at some common culprits:

Overheating – The most common cause of radiator cracking is overheating. This happens when your engine runs too hot for an extended period of time, causing the metal in the radiator to expand and eventually crack or warp. This can happen due to low coolant levels or problems with your cooling fan or thermostat.

Cracking RadiatorsPoor Manufacturing or Installation Quality – Poor quality parts or improper installation can lead to premature wear and tear on your radiator, eventually leading to a crack developing over time as well as leaks throughout the system that may go unnoticed until further damage occurs.

Natural Wear and Tear on Old Systems – Even if you maintain your vehicle well over time, the radiator may eventually crack due to age and normal wear and tear.

Damage from Foreign Objects or Chemicals – If your radiator is exposed to foreign objects or harsh chemicals, it can cause the metal to corrode and weaken over time, leading to cracks in the system. This is especially common for radiators that are located near the front of the vehicle, where debris from the road can quickly cause damage.

How to Fix a Cracked Radiator

If you find that your radiator has cracked, it’s important to repair it as soon as possible before further damage occurs. Depending on the severity of the crack and its location, you can repair it yourself with epoxy or by welding a patch over it. However, if the damage is extensive or if you don’t feel comfortable attempting repairs yourself, it’s best to hire a professional auto mechanic who can accurately assess what type of repair is needed and make sure that everything is done correctly.
