check engine light
"...the check engine light was on. So we proceeded to do our diagnostics and testing..."
The check engine light is a warning light on your car's dashboard that tells you something is wrong with the engine. It could be a small issue or something more serious, so it's important to check it out.
The check engine light is an indicator on the vehicle's dashboard that signals a problem with the engine or emissions system. It can indicate a range of issues, from minor to serious, and requires diagnostics to determine the exact cause.
thermostat
"So a thermostat, what does a thermostat actually do?"
A thermostat is a part in your car's engine that helps keep it at the right temperature. It opens and closes to let coolant flow and keep the engine from getting too hot or too cold.
A thermostat is a component in an engine that regulates the engine's temperature by controlling the flow of coolant. It opens and closes based on the engine's temperature to ensure optimal operating conditions.
internal combustion engine
"So what it does is it allows the engine to warm up quickly, an internal combustion engine."
An internal combustion engine is a common type of engine that works by burning fuel inside it to create power. This is what makes most cars move.
An internal combustion engine is a type of engine that generates power by burning fuel and air inside the engine's cylinders. This process creates a series of controlled explosions that push the pistons and ultimately power the vehicle.
operating temperature
"...It's best to operate at a warm temperature somewhere just under the boiling point of water, maybe around 190, 200 degrees Fahrenheit..."
Operating temperature is the best temperature for a car engine to run. If it's too cold or too hot, the engine won't work as well.
Operating temperature refers to the ideal temperature range at which an engine runs efficiently. For most internal combustion engines, this is typically between 190 to 220 degrees Fahrenheit.
cooling system
"Ideally the radiator fan, the way cooling system works, the thermostat will open up and then it'll flow coolant to the radiator."
The cooling system is what keeps the engine from getting too hot. It moves a special liquid called coolant around to help cool everything down.
The cooling system in a vehicle is designed to regulate the engine temperature by circulating coolant through the engine and radiator. It prevents the engine from overheating and maintains optimal performance under various operating conditions.
radiator fan
"That's why there's a fan. Most cars have electric fans these days. So once the temperature reaches a certain amount, say 205 Fahrenheit, the fan clicks on, cools down, then comes back on and off as it needs to."
The radiator fan helps cool down the engine by blowing air through the radiator. It turns on when the engine gets hot to keep everything from overheating.
The radiator fan is an essential part of the cooling system that helps to dissipate heat from the coolant as it passes through the radiator. It activates when the engine reaches a certain temperature to ensure that the engine remains cool, especially during hot weather or heavy loads.
electric water pump
"Some vehicles actually have electric water pumps that'll flow coolant to keep the coolant flowing through the system so it doesn't get hot pockets in the system. These things are pretty sophisticated compared to what they used to be."
An electric water pump helps keep the engine cool by moving coolant around. It's different from older pumps that were powered by the engine itself, making it more efficient.
An electric water pump is a component in modern vehicles that circulates coolant through the engine and radiator, helping to maintain optimal operating temperatures. Unlike traditional mechanical pumps, which are driven by the engine, electric pumps can operate independently, allowing for more efficient cooling management.
Volvo
"maybe if it's stuck open, like it was the case with this Volvo, you just get no heat in the vehicle in the winter time."
Volvo is a car brand from Sweden that focuses on making safe and reliable vehicles. They are known for their sturdy build and safety features.
Volvo is a Swedish automotive brand known for its emphasis on safety and reliability. Many of its models are equipped with advanced technology and features, making them popular choices for families and safety-conscious drivers.
air filter housing assembly
"that's the air filter housing assembly. There's an intake plenum up above it."
This part holds the air filter, which keeps dirt and debris from getting into the engine. It's important for the engine to run smoothly.
The air filter housing assembly is a component that houses the air filter, which cleans the air entering the engine for combustion. It's crucial for engine performance and efficiency.
plastic assembly
"nowadays, on most cars, when you have a thermostat, it's a plastic assembly that bolts up to the engine."
This refers to how newer cars use plastic parts instead of metal for some components, which can save weight and money but might not last as long.
In modern vehicles, thermostats are often integrated into plastic assemblies, which are lighter and can reduce manufacturing costs. However, they may be less durable than metal counterparts.
starter motor
"...That's the starter motor. So again, if you're doing a starter, yeah, to your right, just right below the thermostat."
The starter motor is what helps start the car's engine. When you turn the key, it spins the engine to get it running. It's usually found close to the engine.
The starter motor is an electric motor that initiates the engine's operation by turning the flywheel. It is crucial for starting the engine and is typically located near the engine block.
oil filter
"...to the left of that, there's another round item. Yeah, that's the oil filter."
The oil filter cleans the engine oil by removing dirt and debris. Keeping it clean helps the engine run smoothly and last longer. It's important to change it regularly along with the oil.
The oil filter is a component that removes contaminants from engine oil, ensuring that the oil remains clean and effective in lubricating the engine. Regular replacement of the oil filter is essential for engine health.
temperature management unit
"temperature management unit or something. It's like $800 and a lot more labor to get out. So this Volvo is actually on the scheme of modern thermostats, not too bad."
A temperature management unit helps keep the engine at the right temperature. It controls how coolant flows to prevent the engine from overheating or running too cold.
A temperature management unit is a component in modern vehicles that helps regulate the engine's temperature by managing coolant flow and other related functions. This is crucial for maintaining optimal engine performance and efficiency.
BMW
"Some cars, they try to manage the coolant flow. I say in this BMW, it did a couple other things than just being a simple thermostat, but proper temperature management is really critical..."
BMW is a car brand from Germany that makes luxury cars. They often use advanced technology in their vehicles to improve performance and efficiency.
BMW is a well-known German automotive manufacturer recognized for its luxury vehicles and performance-oriented models. The brand often incorporates advanced technology in its cars, including sophisticated temperature management systems.
coolant flow management
"Some cars, they try to manage the coolant flow. I say in this BMW, it did a couple other things than just being a simple thermostat, but proper temperature management is really critical..."
Coolant flow management is how a car controls the movement of coolant to keep the engine at the right temperature. It's important for the engine to work well and not overheat.
Coolant flow management refers to the system in a vehicle that controls how coolant circulates through the engine and radiator to maintain optimal operating temperatures. This is increasingly important in modern engines to ensure performance and prevent overheating.
