Long-life coolant is a type of antifreeze that says it can last a long time without needing to be changed, but sometimes it still needs to be checked or replaced.

Term

antifreeze

""...there's several different types out there, color, it doesn't really matter until you get into European cars...""

Antifreeze is a special liquid in your car that stops the engine from freezing when it's cold and from getting too hot when it's warm.

Concept

European cars

""...except for when you get into European cars and I can speak for that because we do have a couple of European cars... domestic automotive technicians do not understand the European cars, you need a European tech to work on them...""

Cars made in Europe sometimes need special care and different fluids than cars made in other places, so it's good to have a mechanic who knows about them.

Term

head gasket

""...now you've got a head gasket problem and it may be deeper than that we won't know until we tear the engine down what's that going to cost, that's the first thing you're going to say""

The head gasket is a part inside your car's engine that keeps important fluids separate and helps the engine work properly. If it breaks, it can cause big problems and cost a lot to fix.

Term

diagnostic time

"so eight hours at whatever the shop rate is that's your diagnostic time to determine what exactly happened and how bad is the engine hurt"

Diagnostic time is when the mechanic looks at your car to find out what's wrong before fixing it.

Concept

engine damage

"and how bad is the engine hurt that's what you got to know, that's being in the know"

Engine damage means something inside your car's engine is broken or worn out, which can make the car stop working properly.

Concept

vehicle longevity

"this is reality if you want to give longevity to your vehicle's engine transmission and its driveline and you want to keep that vehicle as long as you can possibly keep it going"

Vehicle longevity means how long your car can keep running well if you take good care of it.

Term

driveline

"if you want to give longevity to your vehicle's engine transmission and its driveline and you want to keep that vehicle as long as you can possibly keep it going"

The driveline is the part of your car that helps move the power from the engine to the wheels so the car can go.

Concept

you pull it yards

"I'd rather go to you pull it and pick one of those in there and bring it back to life... and that's why a lot of really good looking vehicles are stacking up at the you pull it yards... nobody's going in to pull the parts"

A "you pull it yard" is a place where old cars are kept and you can go there to take parts off the cars yourself. It's a cheaper way to get car parts or even cars that need fixing.

Car

Jeep TJ Wrangler Sport

"but I segue into the very first couple of videos of our 97 Jeep TJ Wrangler Sport that that is now a reliable, safe, long life"

The Jeep TJ Wrangler Sport is a type of Jeep made from 1997 to 2006. It's a popular off-road vehicle that is tough and can handle rough roads well.

Jeep TJ Wrangler

"and so what finally killed that 97 Jeep TJ Wrangler? Cooling system failure"

The Jeep TJ Wrangler is a type of Jeep made between 1997 and 2006. It's a popular off-road vehicle that many people use for adventure and driving on rough roads.

Term

cooling system failure

"and so what finally killed that 97 Jeep TJ Wrangler? Cooling system failure that's what took it out"

Cooling system failure means the parts that keep the engine from getting too hot stop working properly. This can cause big problems for the car's engine.

Term

engine liquid locked

"the engine liquid locked the cooling system was definitely failing"

Engine liquid lock is when liquid gets into parts of the engine where it shouldn't be, stopping the engine from running because liquids can't be squeezed like air can.

Term

cooling system pressure

"the pressure got so high in the cooling system on that little Jeep that it blew the upper radiator hose connection to the radiator"

The cooling system uses pressure to keep the engine from getting too hot. But if the pressure gets too high, parts can break and cause problems.

Term

engine transmission failure

"engine transmission failure engine transmission failure"

When the engine or transmission breaks down, the car won't work properly. This can happen if parts aren't taken care of.

Term

cooling system maintenance

"on the back of the bottle it says that you should have the system maintained on a regular basis... and you haven't been maintaining your cooling system"

Taking care of your car's cooling system means checking and fixing parts that keep the engine from getting too hot or too cold, like the radiator and hoses.

Term

acid corrosion

"the pH balance and the alkalinity acid corrosion level goes right off the chart"

Acid corrosion means the coolant gets too acidic and starts to eat away parts inside the engine.

Part

intake gaskets

""coolant in the engine intake gaskets letting go while on the highway""

Intake gaskets are seals that help keep air and liquids in the right places inside the engine. If they break, the engine might not work well.

Term

alkalinity

"what's the acid corrosion level pH balance and alkalinity"

Alkalinity means how much the coolant can stop acids from hurting the engine parts.

Term

pH balance

"what's the acid corrosion level pH balance and alkalinity"

pH balance tells us if the coolant is more like lemon juice (acidic) or soap (alkaline), which helps keep the engine safe.

Concept

maintenance-free coolant claim

"it's maintenance free my friends you don't have to do a stinking thing to the vehicles cooling system for seven whole years"

Some coolants say they don't need to be changed for a long time, but that's not always true. You still need to check and change it sometimes to keep your car safe.

Term

planned obsolescence
