5 Common Automotive Cooling System Issues that Shouldn’t Be Ignored

Express Oil Change & Tire Engineers • April 25, 2025

Your car’s cooling system plays a vital role in keeping the engine at a safe operating temperature. When components within this system begin to fail, it can lead to overheating, engine damage, and costly repairs. Ignoring early signs of trouble can quickly turn a minor issue into a major headache. At Express Oil Change & Tire Engineers, we provide expert cooling system repair in the greater Orlando area. Here are five common automotive cooling system problems that should be addressed as soon as possible.


Coolant Leaks

One of the most common cooling system problems is a coolant leak. Coolant can escape from a number of places, including the radiator, hoses, and water pump. If you notice a sweet-smelling puddle under your vehicle or see the coolant level dropping without explanation, it’s important to investigate immediately. 


Overheating Engine

An overheating engine is a clear sign that the cooling system isn't functioning properly. Overheating can be caused by a variety of issues, including a stuck thermostat, a malfunctioning radiator fan, or low coolant levels. If your temperature gauge starts climbing into the red or you see steam coming from under the hood, pull over and shut off the engine as soon as it’s safe. 


Clogged Radiator

Over time, debris can build up inside the radiator, reducing its ability to dissipate heat. A clogged radiator can prevent coolant from flowing properly and lead to overheating. If your car is running hot and you haven’t had the radiator flushed in a while, this could be the culprit. 


Faulty Thermostat

The thermostat controls the flow of coolant between the engine and the radiator. When it fails, it can either stick in the closed position, causing the engine to overheat, or remain open, preventing the engine from reaching optimal temperature. Replacing a faulty thermostat is relatively inexpensive and can prevent much larger problems.


Worn or Cracked Hoses

Hoses are responsible for transporting coolant. With age and heat exposure, they can become brittle and develop cracks. If you see bulges, splits, or dried-out rubber, it’s time for replacement. A ruptured hose can cause an immediate coolant loss and rapid overheating, so it’s best to address these signs early before they lead to a breakdown.
