Hot oil may flow freely, but it will also induce serious burns if you don’t let it cool down before changing it. Here is a tip for speeding up your oil change – if the engine is cold, fire it up and run it for 2-3 minutes.
Should I let engine cool before changing oil?
TOM: So, for that reason, here’s what we recommend. First, don’t do the oil change when the engine is red-hot. Let it sit for half an hour or an hour before starting your work. The oil will still be warm enough to flow easily, but the exhaust manifold won’t be glowing red and 800 degrees.
How long does it take for an engine to cool down for oil change?
Under normal circumstances, it takes a minimum of 30 minutes for an overheated engine to cool down to a temperature where it is safe to inspect it and potentially work on it.

What is the fastest way to cool off oil?
One way to do this is to put just water in the larger container and then put ice in the area surrounding the sides of the oil container. The water will help conduct the heat even from the underside of the oil container into the ice.
Can I drive my car straight after putting oil in?
You can drive immediately, assuming you did an oil change and not re-assembled an engine (fully dry). With oil changes, some of the old oil is still there around the engine, and you don’t need to wait before driving off, a short 15–30 second idle would be adequate to have enough oil circulation.
How do you cool down engine oil?
Oil to water (or O2W for short) transfers the oil’s heat into the engine’s coolant system through a unit typically called a heat exchanger. Another route is oil to air (or O2A for short), which transfers the oil’s heat through an exchange with airflow through a unit typically called an oil cooler.
Can I pour water on my engine to cool it down?
If your engine is still hot, don’t pour cold water on it. Pouring cold water on a hot engine can cause serious damage. Instead, let the engine cool down on its own or use a coolant to help speed up the process. Be sure to follow the instructions on the coolant container, as some coolants need to be diluted before use.
What do you do when oil temp is hot?
Bring your car in for service to determine whether you need more oil or a different type of oil, and to make sure your engine hasn’t been damaged from the hot oil temperature.
How do you stop oil from overheating?
To maintain the proper oil temperature, use a clip-on deep-fry thermometer and keep close watch. If the oil starts lightly smoking, that’s a sign that it’s overheated and starting to break down; remove the pot from the heat until the oil cools to the correct temperature.

In only a few minutes, oil can overheat and the vapours burst into flames. Many people are killed or seriously burned in kitchen fires that start this way.
How can I cool down my car engine while driving?

Can I drive with a hot engine?
If your car is overheating, you should definitely not drive it. This could be due to several factors, including low coolant levels or a faulty cooling system. Driving an overheated car puts additional strain on the engine, leading to further damage and costly repairs down the road.
How long can a car overheat before damage?
The furthest you can drive an overheating car is about a ¼ mile before you risk irreversible engine damage. While some vehicles could still make it as far as 20 miles, we would never recommend driving very far with an overheating engine.
Does turning on your heater cool your engine?
Sometimes the engine may overheat while you are on the road, with no place for pulling over. When this happens, turn on the car heater. The heater taps into the car’s cooling system and takes heat from the engine coolant to warm the air that is blown into the cabin.
