Engine Overheating Causes:

Normal Temperature Ranges and Coolant

Your vehicle’s cooling system is designed to keep your engine running within normal temperature ranges (typically 195 to 220? F depending on make and model). Coolant will boil at 225? F, but pressure created by the radiator cap and coolant blend ratios also help to increase the temperature that can be withstood.

Coolant System Causes

The most common cause of overheating is also the most simple, coolant. If your coolant level is too low, your vehicle’s cooling system cannot work properly. Coolant levels can drop through normal use, but if you notice significant drops in the fluid level check for coolant leaks or the possibility of a clogged radiator. To learn more about the warning signs, visit Signs of a coolant leak . Also make sure to use the coolant ratio recommended for your vehicle. Consult your owners manual for the correct levels.

Fan, Pump, Hose and Thermostat Failures

A faulty radiator or radiator fan can cause engine overheating if proper cooling is not occurring. Additionally, when a water pump, one of the most important parts of the cooling system, malfunctions it can lead to leaks or bearing problems that can cause overheating. Hose damage and hose collapses can also play a part in inadequate cooling, as well was a stuck or faulty thermometer.

The Consequences of Overheating

The damaged caused by an overheated engine can be serious. Overheating can cause damage to pistons, cylinders, bearings and valves, as well as a number of other vital engine components. As a result, warning signs of overheating should never be ignored; shut down your vehicle at the first indication that your engine may be operating above normal temperatures!

Engine Overheating Prevention

Avoid overheating by keeping an eye on your vehicle’s temperature gauge and coolant levels and regularly inspecting belts and hoses. Since a working radiator cap provides the pressure needed to allow for higher coolant temperatures, make sure your cap is working properly and replace it if needed. Never remove the radiator cap when the engine is hot!

Professional coolant and radiator flushes are also available to help maintain a well functioning cooling system, and as always, the experts at Pep Boys are happy to discuss your specific vehicle’s recommended maintenance and offer a range of services to keep your vehicle on the road.
