Niall Jenkins

"I'm your host, Niall Motormouth Jenkins, coming to you straight from the Car Connection Workshop, where we mix a little humor, a little know-how, and a whole lot of horsepower."

The host of this radio show and podcast, who shares practical advice on how to fix and maintain your own car to save money.

Part

Chrysler 3.6L Pentastar engine

"The only one that wasn't mentioned in all my research, which I found very interesting because I know the 3.6 Panistar engine. It's not bad, but it isn't great."

A very common 6-cylinder engine found in many modern SUVs, minivans, and trucks made by Jeep, Dodge, and Chrysler. It is a reliable workhorse, though it has a few well-known design flaws that require attention as it ages.

Term

lubricity

"So instead of the coefficient of friction, I'll use they lose their lubricity, their slipperiness, their slickeriness. That's what happens."

A technical term for how slippery a fluid is. Good fluids keep metal parts from rubbing directly against each other, preventing them from wearing out or melting from friction.

Part

cooling system

"And number four, cooling system is King folks. So if you're thinking up till now, you've gotten lucky with the cooling system. Well, the heat will find you out on this one. Cooling system failures, the number one system that is mostly most neglected on almost every automobile."

The parts of a car (like the radiator, water pump, and hoses) that work together to keep the engine from getting too hot. It circulates a special liquid to absorb engine heat and blow it away.

Part

air dam

"And you go, oh, that's that's probably not needed. Yeah, it is. They're called air dams. They're trying to push as much air up into the engine bay to get heat out the backside and away from the motor."

A plastic shield under the front bumper of a car that helps direct wind. It makes the car slide through the air more easily and pushes cool air up into the engine to keep it from overheating.

Part

intake plenum

"It's well on its way to the junkyard because there's a lot of plastic plastic valve covers plastic intake plastic intake plenums. The whole top of the engine is all plastic now."

A chamber that holds air before it gets sucked into the engine's cylinders. It ensures each cylinder gets the right amount of air, but because modern ones are made of plastic, they can crack when they get too hot.
