There will come a point you will fall victim to an overheating engine. The temperature indicator needle just camps on the red and won’t come down. In such instances, the last thing you need to do is keep driving, explains jerrylambertautomotive.com, an expert in radiator repair in Salt Lake City.
Doing so only serves to compound the problem. Instead, look for a safe place to pull over and get off the road.
Don’t switch off the engine
Instinctively, you will want switch off the engine when the temperature needle hits red. While that might seem logical since the engine is overheating, it is not the right thing to do. You should put the car in park and just idle the engine. The only time you should turn it off is when the coolant is leaking.
See, turning off the engine kills the car’s cooling mechanism, causing it to boil over. On the other hand, idling keeps the coolant running through the engine and soaking up the heat.
Do rev the engine
It might seem counterproductive to rev an overheating engine, but that’s not the case. As the engine is idling, rev the engine for a little while. Doing so increase the speed at which the coolant flows through the engine. If your car has a mechanical fan, revving the engine increase the airflow to aid the cooling process.
Cranking the heater at full blast also helps to cool an overheating engine. Doing so causes the heater core to extract more heat from the engine coolant. However, if you notice that the engine is not cooling or the ducts are not blowing hot air, cut off the engine.
You have a bigger problem such as coolant flow issue on your hands, and that calls for the intervention of an expert.
An overheating car engine can prove to be a nasty experience, especially when in the middle of a long journey. While sometimes, it is easy to resolve such a problem, and sometimes the problem calls for expert intervention.
