Four Reasons Why Your Car Overheats

One of the most frustrating problems that any motorist can encounter is car overheating. Here’s a look at the common reasons why cars overheat and what motorists can do about it.

A Stuck Thermostat

One of the most common reasons for car overheating is a stuck thermostat. When the thermostat sticks or freezes, it will block the flow of coolant to your engine. The easiest way to check if your thermostat is not open is to feel for the upper radiator hose. Once the engine warms, the radiator hose should become warm. If it doesn’t then the thermostat isn’t opening properly.

A Leak in the Vehicle Cooling System

In simple terms, if the vehicle is losing coolant then there won’t be enough coolant in the system to keep the vehicle cool. This is easy to diagnose as the radiator will be low on fluid and the car will leak coolant. Car owners are advised to look for coolant on the floor of the garage, the leak is more likely than not to be down to a small hole or crack in and around the welds of your radiator.

A Faulty Water Pump

The water pump is a vital part of your cooling system, since it is responsible for circulating the coolant throughout the engine. If a faulty water pump is the suspect, your vehicle won’t run for more than a few minutes without overheating.

Malfunctioning Cooling Fan

Your vehicle will have two types of fans which are electric and mechanical. The electric fan will be activated automatically once the vehicle reaches operating temperature, or when the AC is turned on. If the cooling fan fails to start, it will need to be replaced. The mechanical fan will run all the time and it will work harder the faster the engine heats up. When the vehicle is warm, the fan shouldn’t turn as quickly or freely.

These are some of the most common causes for engine overheating. Motorists are advised to remember that a great deal of damage can be done to your vehicle if it overheats consistently. It’s wise to be vigilant, otherwise you may be faced with a large bill for any work that needs completing.
