Nissan Pathfinder
Car

Nissan Pathfinder

The Nissan Pathfinder is an SUV, meaning it’s a larger vehicle meant for carrying people and gear. A 1989 Pathfinder is an older model, so it may need more maintenance than newer cars. People talk about them because they’re built to handle everyday driving and some rougher roads, but they can be tricky when they get old.

Term

engine warms up

When the engine is cold, oil doesn’t flow as easily as it does when everything is warmed up. That can make certain noises show up for the first few minutes after starting.

Term

oil starvation

Oil starvation is when the engine doesn’t have enough oil flowing where it needs to go. That can cause noisy sounds because parts aren’t getting proper lubrication, and it can happen more when the engine is cold or if the oil system is clogged.

Part

oil pump

The oil pump is what pushes oil through the engine to keep parts lubricated. If it’s weak, the engine may not get enough oil pressure, and you can hear unusual noises.

Part

oil screen

The oil screen is like a protective filter inside the engine’s oil system. If it gets clogged, less oil can get through, and the engine may not be lubricated properly.

Term

oil pan

The oil pan is where engine oil sits at the bottom of the engine. The oil has to be picked up from there and sent through the engine—if that pickup can’t keep up, the engine may not get enough lubrication.

Term

pickup screen

The pickup screen is like a small filter on the oil intake. If it gets clogged, oil can’t flow properly, and the engine may start making noise because parts aren’t getting enough oil.

Term

valves making noise

When the valves make noise, it usually means the engine isn’t lubricating that part well. In this story, they think the oil isn’t getting to the valves properly at speed.

Term

oil change

An oil change means replacing the old engine oil (and usually the filter) with fresh oil. The goal is to keep the engine properly lubricated so parts don’t run dry or get noisy.

Term

crankcase

The crankcase is the bottom part of the engine where oil collects. If oil doesn’t drain back there correctly, the engine can end up running with less oil than it needs.

Car

Colt Vista

They’re talking about a specific car called the Colt Vista. Their point is that if you don’t change the oil for a long time, dirty sludge can clog the oil system and cause problems.

91 Accord
Car

91 Accord

This is a 1991 Honda Accord. The big maintenance item mentioned is the timing belt, which is a belt that keeps the engine’s timing correct. Replacing it is more involved than most normal services.

Term

timing belt

The timing belt is a belt inside the engine that keeps the engine’s moving parts working in the correct order. If it fails, the engine can be damaged, so mechanics replace it at the recommended mileage.

Term

labor rate

Labor rate is the hourly charge a shop applies to technician time. Even when parts prices are similar, differences in labor rate can change the total cost of a job like a timing belt replacement.

Term

water pump

The water pump moves coolant through the engine so it doesn’t overheat. Mechanics sometimes replace it during a timing belt job because it’s easier to do while the engine is already partly taken apart.

Term

counterbalance shaft belt

Some engines have extra parts to reduce shaking. This “counterbalance shaft belt” is the belt that helps run that vibration-reducing system, so it may need replacement along with the main timing belt.

Term

cooling systems

The cooling system is how the car keeps the engine from overheating. A flush is when the old coolant is cleaned out and replaced so the system works properly.

1988 Oldsmobile Cutlass Sierra
Car

1988 Oldsmobile Cutlass Sierra

This is a specific older car: a 1988 Oldsmobile Cutlass Sierra. It’s the kind of mid-size American car from the late 1980s, so it’s useful to know because parts and repairs are usually straightforward compared with newer cars.

Term

starter engage

When you turn the key, the starter motor has to “grab” the engine so it can spin it. If it grabs and then lets go almost immediately, the engine won’t start right away.

Term

starter kicks out too early

The starter is supposed to stay connected long enough to spin the engine. If it disconnects too early, the engine doesn’t get spun up and won’t start.

Term

starter drive

Your starter has a small “engaging” mechanism that grabs the engine so it can crank. If that piece fails, the starter may not actually turn the engine reliably.

Term

Bendix drive

The Bendix drive is an older name for the starter’s “gear-engaging” mechanism. It’s what helps the starter gear connect to the engine so the engine can turn over.

Person

William Bendix

William Bendix is the person the “Bendix drive” name comes from. The hosts are basically saying the name stuck, even if most people don’t know who he was.

Term

factory reconditioned starter

A factory reconditioned starter is a starter motor that’s been rebuilt and tested by a professional remanufacturer or the original manufacturer’s reconditioning process. It’s typically sold as a replacement to reduce the chance of repeat failure compared with a poorly rebuilt unit.

Concept

abandoned at the airport

They’re talking about a car that was left sitting at an airport for a long time. When nobody is paying attention to it or making payments, it can end up being handled like an unpaid asset and sold off.

Concept

purchases the Lexus

He didn’t buy it from the person who originally left it—he bought it through the bank. That usually happens when a financed car isn’t being paid for, so the bank ends up selling it.

Term

dragon tracks

“Dragon tracks” sounds like a funny name for ugly streaks or lines on a car’s exterior. It’s usually the kind of cosmetic problem that a car detailer might be able to remove or reduce.

1966 Volkswagen camper van

This is a vintage Volkswagen van from 1966 that people often convert or buy for camping. It’s known for being a classic “road trip” vehicle, and it has a simple, old-school design.
