Coolant Systems


Coolant Systems | Wayne Truck & Trailer LLC

Your cooling system in your vehicle not only reduces the temperature when your engine gets too hot but also regulates that temperature continually. It can be overlooked, but this component is one of the most vital aspects of your engine. 

Signs of a Malfunctioning Coolant System

Your vehicle cooling system is vital for keeping your engine at the correct temperature at all times. Your engine works best in high temperatures but can overheat if not taken care of. If it gets too hot, the coolant flushes through to lower the temperature down–in the same way, it also raises the temperature if it gets too cold. 


Most of the time you can pick up on various signs that can point to a malfunctioning coolant system. Even if you’re unsure, it’s always best to treat these symptoms as potential issues and see a professional to help. Some  signs include:

  • Overly heated hood
  • Steam from the engine 
  • Multiple dashboard lights active
  • Liquid leaking (yellowish color) 
  • Squeaking and ticking noises 

What to do If Your System is Overheating

Driving your vehicle while the system is overheating can lead to various issues–not to mention potential fire within the engine.

If you notice your engine overheating through some of the abovementioned signs, contact Wayne Truck & Trailer to inspect the vehicle. 


At Wayne Truck & Trailer, we offer roadside assistance, as well as towing services when needed. Make sure you understand the signs of an overheating system in order to keep this from happening. 


Components of the cooling system

It’s helpful to know what exactly your cooling system consists of to increase your awareness of potential problems. Some of the main components include:

  • Radiator/coolant reservoir: the heat exchanger of the engine, helps to transfer the heat of the water coming from the engine 
    • Radiator Cap: part of the pressure regulation system. Although it’s just a small “plastic-looking” cap–it’s vital for the whole CS.
    • Water pump: helps circulate the coolant throughout the engine
    • Thermostat Housing: allows the coolant to go back and forth from the engine to the radiator. At 181 degrees, it begins to open up to allow the coolant to move–before that temp, the thermostat cuts off the coolant so it can flow through the radiator.  
  • Expansion tank: allows for thermal expansion–without this tank, the coolant would run through the radiator and leak out the valve since it has nowhere to go.
  • Engine fan: connected from the crankshaft itself(in a 4-cylinder engine)
  • Tubes/lines: pressure release lines–if the engine builds up too much pressure, these lines help release that pressure
