About this episode

Ford’s “we know SUVs are bad” rationalization sparks jokes about money addiction, followed by practical calls. Ben asks about skipping “oil and lube” on a high-mileage 1987 Nissan Stanza—hosts explain most modern cars have sealed joints with no grease fittings, but timing belts can be critical. Faith reports a 1992 Camry wagon locking her in; they suggest a likely recall/TSB and relay-related fix. Other segments cover fly infestations at horse shows, Stump the Chumps (Ford screeching = serpentine belt), a brakes-material puzzler, and a math probability game. Final advice warns about burning smells from serpentine belt pulleys and debates using Coleman fuel in a pinch.

Company

Carvana

"This message comes from NPR sponsor, Carvana, making buying a car 100% online with real, transparent pricing and customizable financing that fits your budget. Browse thousands of cars and get yours delivered."

Carvana is a company that sells cars online. Instead of going to a dealership, you pick the car on their website and they deliver it to you.

Concept

customizable financing

"This message comes from NPR sponsor, Carvana, making buying a car 100% online with real, transparent pricing and customizable financing that fits your budget. Browse thousands of cars and get yours delivered."

Customizable financing refers to tailoring loan terms—like the down payment, monthly payment target, and loan length—to fit a buyer’s budget. It’s relevant because different terms can change the total amount paid over time, even if the monthly payment looks similar.

Concept

delivery fees

"Delivery fees and terms may apply. Hello and welcome to Car Talk from National Public Radio with us, click-and-collect the"

Delivery fees are extra charges for bringing the car to you. They can change the final price, so it’s good to look at them up front.

Brand

Ford Motor Company

"Now, this is an interesting announcement from Ford Motor Company. This is brilliant. Here's what Ford Motor Company publicly announced."

Ford Motor Company is a big car manufacturer. In this segment, they’re the ones making the announcement being discussed.

Car

1987 Nissan Stanza

"[251.6s] 1987 Nissan Stanza with 195,000 miles on it. [255.7s] Good for you."

A Nissan Stanza is a regular passenger car from the 1980s. The point here is that even if you change the oil, other scheduled maintenance can still be overdue on a high-mileage car.

Term

timing belt

"[287.4s] Okay. [287.8s] So you've never replaced like the timing belt? [290.2s] No."

The timing belt is like a timing “sync” belt inside the engine. If it breaks, the engine’s timing can get thrown off and it can cause major damage.

Part

ball joints

"And if you are, then lubing the ball joints becomes kind of. Yeah, it's like fixing the curtains on the Titanic."

Ball joints are little joints in the suspension that help the wheels move up and down and steer. Some older cars have grease points for them, but many newer cars use sealed parts so you don’t grease them.

Term

grease fittings

"...many cars don't even have a provision for greasing them. There are no grease fittings on the car. You remember, I mean, you must have had a grease gun..."

Grease fittings are little metal nipples where you attach a grease gun. If your car doesn’t have them, the parts are usually sealed and maintenance doesn’t include greasing.

Term

Zerk fitting

"It's called a Zerk fitting. Yeah."

A Zerk fitting is a little grease nipple on some car parts. If you see one, you can use a grease gun to add grease and help the part last longer.

Concept

boot bulge

"...you give it a couple of pumps and either you'll see the boot bulge up, which means you put too much grease in it."

The boot is the rubber cover that protects the joint. If it starts to bulge a lot while greasing, that can mean you’re putting in too much grease.

Term

automatic door locks

"[476.5s] I drive a 92 Camry wagon. [478.8s] I have a problem with the automatic door locks. [482.1s] The way I usually lock the car is that I open the door"

Automatic door locks are the car’s built-in locking system. Here, the problem is that once the doors lock, the driver can’t get back out.

Concept

couldn't reproduce the problem

"[529.1s] And I had it at the dealer recently [531.2s] and, of course, I couldn't reproduce the problem for them. [534.2s] So they don't believe me. [535.8s] Hey, Camry had this problem."

“Couldn’t reproduce the problem” means the dealer couldn’t trigger the issue during diagnosis. Many intermittent electrical or safety-related faults only happen under certain conditions, so the lack of a repeatable symptom can delay repairs or make the issue harder to validate.

Concept

technical service bulletin

"that there's probably a technical service bulletin on this car. And you'd like them to do a little research and find out."

A technical service bulletin is like a manufacturer’s “heads up” to mechanics. It tells them about a common problem and what fix usually works best.

Term

relays

"There must be some relays that have to be replaced. I don't know what the final result was."

A relay is an electrical switch that helps your car control things like lights or fans. If it goes bad, that part of the car can stop working or act weird.

Term

license plate

"Into your license plate or VIN, get a real offer down to the penny and schedule a pickup on your time. No surprises."

A license plate is the number on your car’s front or back. Some services can use it to find your car in their records, but the VIN is the exact ID.

Term

wheels used to be made out of wood

"[775.4s] For example, wheels used to be made out of wood [777.9s] and they were made out of steel"

Long ago, some vehicle wheels were made of wood instead of metal. Wood wheels don’t last as well and can wear out or get damaged more easily than modern wheels.

Term

wheels were made out of steel

"[777.9s] and they were made out of steel"

Steel wheels are stronger and more durable than wood. Today, many cars use metal wheels too—often aluminum—because it can be lighter while still being strong.

Term

aluminum alloy

"and now they're made out of some kind of magnesium, [781.0s] aluminum alloy."

An aluminum alloy is aluminum plus other metals to make it stronger. Cars use it because it’s lighter than steel and resists rust better.

Term

plastic

"[785.8s] and now plastic and other things. [788.2s] So I'm going to do this little what am I game?"

Plastic is used a lot in car interiors because it’s lighter and easier to shape. It can also be made tough enough to handle bumps and impacts.

Part

clutches

"[931.0s] I mean, I was working on clutches, but the wood. [936.6s] And in fact, if it weren't for the wood,"

A clutch is what helps a manual-transmission car change gears smoothly. It lets the engine and the gearbox “disconnect” briefly so you can shift without damage.

Term

steering wheel

"It's going to get on the seats. It's going to get on the steering wheel. You're going to get in the car."

The steering wheel is what you use to turn the car. If something gets on it, it can feel slippery or dirty, which makes driving less comfortable and safe.

Concept

Stump the Chumps

"It's time to play Stump the Chumps. This is the portion of the show where we revisit a previous call to find out if our advice fell into the realm of useful, useless."

This is a part of the show where someone describes a car problem and the hosts try to figure out what’s wrong. It’s like a puzzle, but for car issues.

Term

turn on the heat

"It squealed whenever she turned on the heat. I guess her mother-in-law likes it cold in the trunk."

They notice the noise happens when the heater is turned on. That usually means the problem is connected to the car’s heating/air system, like the fan or a control that moves air.

Term

air conditioner

"So what do we really tell her? Well, we had two solutions, a cheap one and an expensive one. And they both had to do with the air conditioner."

Your car’s air conditioner is what cools the inside of the car. Even when you’re trying to defrost the windshield, many cars still turn on the A/C to help dry the air.

Part

serpentine belt

"So they put a new radiator hose on it, also a new serpentine belt. And when I drove out of the dealership, it still smelled."

The serpentine belt is the main belt that powers several parts of the engine. If it starts slipping or rubbing, it can get hot and smell like burning rubber.

Concept

check by removing the belt and turning pulleys by hand

"If they merely take the belt off and try to turn everything that the belt turns by hand, they will find one of those things is not turning freely and that's your culprit."

A good way to find the problem is to take the belt off and spin the pulleys by hand. If one pulley feels rough or won’t spin freely, it’s likely the failed part causing the belt trouble.

Term

overheating the belt

"And what it's doing is it's overheating the belt and burning up the rubber. I'm with it."

Belts get too hot when they’re slipping or when a pulley isn’t spinning normally. Heat damages the rubber, making the belt more likely to break.

Term

Coleman fuel

"and about very often I have Coleman fuel, like a gallon of Coleman fuel. And I'm wondering if I can put that into the car rather than... What is Coleman fuel anyway?"

Coleman fuel is the fuel people use for camping stoves and lanterns. It’s very flammable, so carrying it in a car—especially inside the cabin—can be risky if it leaks or fumes build up.

Term

kerosene

"[1873.0s] No, I mean, I think it's kerosene, isn't it? [1876.5s] No, no, it's definitely not kerosene. [1884.2s] Kerosene will not, actually we'll burn at room temperature, but."

Kerosene is a fuel that doesn’t evaporate as easily as gasoline. Because of that, it usually needs more heat to burn.

Term

volatile

"[1878.4s] No, it's not kerosene. [1879.4s] Because the match on it flares up like gasoline. [1880.8s] Yes, it is much, much more volatile."

Volatile means the liquid turns into vapor easily. Fuels that are more volatile catch fire more easily.

Term

Coleman lantern

"And I have a Coleman lantern. Ask her to look, go down to the basement and read what it says on the can."

A Coleman lantern is a portable camping light designed to run on Coleman fuel. The fuel type matters because it’s formulated to vaporize and burn properly in the lantern’s burner system.

Term

petroleum distillates

"I think the side of the can says something like, contains petroleum distillates. Yeah. Which is what gasoline is too."

Petroleum distillates are fuels made from refined crude oil. If the label says that, it usually means it’s a fuel that behaves a lot like gasoline.

Concept

minivans

"And even though mothers everywhere whip their minivans around and head back to DC for another protest, whatever they hear us saying."

A minivan is a family car with sliding doors and lots of room inside. People use them for everyday driving like school drop-offs and road trips.
