What is the primary purpose of the oil cooling system?
Oil cooling is the use of engine oil as a coolant, typically to remove surplus heat from an internal combustion engine. The hot engine transfers heat to the oil which then usually passes through a heat-exchanger, typically a type of radiator known as an oil cooler.
When draining the engine oil the engine should be fully cold for best results?
Most oil experts say it's better to drain the oil when it's hot instead of when it's cold, for several reasons: Oil viscosity is thinner when it's hot, so it drains more quickly and completely out of the engine than when it's cold.
What is used to force coolant through the cooling system?
Thermostat. The thermostat is simply a valve that measures the temperature of the coolant and, if it is hot enough, opens to allow the coolant to flow through the radiator.
What is involved in dressing the engine?
Technician B stated that "dressing the engine" refers to coating the engine with coolant and lubricating oil. Which of the following statements about this scenario is true?
What is the cooling system?
cooling system, apparatus employed to keep the temperature of a structure or device from exceeding limits imposed by needs of safety and efficiency. If overheated, the oil in a mechanical transmission loses its lubricating capacity, while the fluid in a hydraulic coupling or converter leaks under the pressure created.
How do oil cooling systems work?
The oil is going to enter the oil cooler while its temperature is still high. Inside the cooler, the oil will move around the pipes that are fitted with fins that release heat. Once the oil is processed, it will leave the cooler at a temperature that is already colder. This cycle will continue repeatedly.
Is it better to check oil hot or cold?
If checking the oil yourself, make sure the car is parked on level ground and, with most cars, the engine is cold, so you don't burn yourself on a hot engine part. (With some cars, the automaker recommends that the oil be checked after the engine has been warmed up.)
Can I add oil when engine is hot?
Adding Oil When The Engine Is Warm
Ideally, you should change the oil when your automobile is warm. ... After a few minutes, the oil is less viscous and will flow easier. The oil will get hot enough, so the old oil doesn't stick to the oil pan and other engine parts.
Can you change oil when engine is cold?
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. The oil will warm up to about 100 degrees, which is not hot enough to burn you, but warm enough that it will flow easily. If the vehicle has been driven, let it sit for 20-30 minutes before draining the oil.
What is the purpose of the radiator?
In the simplest terms, the radiator is the central component of a vehicle's cooling system. Its primary function is to monitor and regulate a vehicle engine's temperature and prevent it from overheating.
How does the cooling system work in a car?
The cooling system in your car works by sending the coolant through passages in the engine block and heads. As the coolant flows through these passages, it picks up heat from the engine. The heated fluid then makes its way through a rubber hose to the radiator in the front of the car.
How does coolant flow through a radiator?
The coolant flows through the thin tubes that make up the core of the radiator and is cooled by the air flow through the radiator. From there, it flows out of the radiator, through the lower radiator hose and back to the water pump. By this time, the coolant is cooled off and ready to collect more heat from the engine.
What is the type of oil used for a newly rebuilt engine?
When breaking in any new or rebuilt engine, we recommend a dedicated Break-In Engine Oil. These are all conventional (mineral-based) oils with higher levels of ZDDP.
What does lugging an engine mean?
Similarly, lugging the engine refers to trying to accelerate when you're in too high a gear. So put most simply, you're straining the engine. You're making it struggle. Imagine if you were on your 10-speed bike, and you got to a steep hill and tried to climb it in 10th gear.
What should be done to help prevent rear cylinder distortion?
To avoid cylinder distortion, bore diameter checks are made before, during & after honing. It is critical to properly simulate normal block stresses during cylinder honing to minimize effects from cylinder profile changes during engine operation.
