Because your engine essentially operates by setting off thousands of small explosions, it’s necessary for a complex cooling system to disperse any heat. Overheating can not only cause inconvenient breakdowns, but it can also be incredibly dangerous. That’s why we’ve put together a list of tips on preventing engine overheating.
According to wikiHow, you should always monitor your temperature gauge. Any time the heat creeps into the “H” section, pull over and turn your car off. Overheating can cause the engine to fail, crack, or even explode. If you see steam coming from the under the hood, stop immediately. Be careful around a hot engine, as burns can occur very easily.
Preventing overheating starts with the coolant. You should regularly check antifreeze/coolant levels. Simply check the reservoir (be aware of “hot” and “cool” levels) and top off if necessary. If it is consistently low, you may need to look for leaks. Not only should you look under the car for dripping areas or pools of coolant, but you should also feel hoses for wet spots.
Flushing your cooling system is also necessary every few years. Buildup can cause blockage, restricting the flow of coolant. Radiators often develop calcium and lime residue, especially if you use a large ratio of water in the system.
If your car is running warm, try turning on the heater. Heat is taken directly off the engine block, so this may help cool the car a little. Always turn the A/C and other unnecessary accessories off. If necessary, you may just want to turn the car off but keep the ignition on (battery only) as this will keep the radiator fan and blower on. Finally, be sure to avoid rush hour traffic if your car tends to overheat.
