The Car Show with Dane Donovan - 5/16/2026

The Chevrolet Cavalier convertible is a late-1990s/1990s-era compact that’s known for being a simple, affordable platform—so repairs often come down to basic, replaceable components. In this episode, the hosts are discussing a 1996 model that’s been restored after sitting outside and getting water intrusion.

A blower fan is the fan that pushes air through the HVAC system into the cabin. Replacing the blower fan can restore airflow even if the air conditioning itself still won’t work.

“Freon” is a common nickname for refrigerant—the chemical that absorbs heat inside the AC system and releases it elsewhere. Opening the AC system can vent refrigerant, which then requires proper recovery and recharging.

Manifold gauges are the set of pressure gauges used to diagnose and service an AC system. They help you read refrigerant pressures to determine whether the system is low, overcharged, or not operating correctly.

The Dodge Dakota is a midsize pickup, and this one is described as a 4x4. In the segment, the hosts are troubleshooting fuel-system issues on this truck, including a recurring check-engine-style code and an evaporative emissions-related problem.

A smoke test is a diagnostic method where technicians introduce visible smoke into a sealed vacuum/evaporative system to find leaks. If smoke escapes at a fitting, seal, or hose connection, it pinpoints the leak location without guessing.

A charcoal canister is part of a vehicle’s evaporative-emissions system. It stores fuel vapors from the tank so they don’t vent to the atmosphere, and if liquid fuel gets into it (for example from overfilling or a leak), it can become contaminated and cause drivability/emissions trouble.

The AC clutch is the electromagnetic coupling that engages the air-conditioning compressor when the system calls for cooling. When it fails, the compressor may not spin, so the cabin won’t get cold even if the rest of the system is intact.

The AC compressor is the pump that pressurizes the refrigerant, which is what makes air-conditioning possible. If the compressor is failing, replacing only a small related part (like the clutch) may not fix the underlying problem, because the compressor’s internal wear can still cause leaks or poor cooling.

A vacuum machine is used during A/C service to evacuate the system and remove air and moisture. After evacuation, technicians can verify the system holds pressure (or holds vacuum) to help confirm there isn’t an active leak.

In an A/C service, “evacuate” means pulling the refrigerant out of the system and removing air and moisture using a vacuum machine. This is necessary before recharging so the system doesn’t have contaminants that can prevent proper cooling.

An automotive A/C system is sealed and operates under pressure because the refrigerant needs the right pressure to change state and move heat. If pressure drops due to a leak, the system can’t circulate refrigerant correctly, so cooling performance suffers.

“Pressurizes” here means the service machine fills the A/C system to a test pressure to confirm it holds. If it doesn’t hold pressure, that indicates a leak, and the technician can’t accurately diagnose or recharge until the leak is found.

Fluorescent dye is added to the A/C system so leaks can be found later. After the system runs for a bit, a technician uses a black light to locate where the dye escaped, pointing to the leak location.

A black light (UV light) is used to make the fluorescent dye glow. This lets the technician visually identify the leak path after the A/C has been operating for some time.

Rubber O-rings are sealing rings used at A/C connections (like when removing and reinstalling lines or a compressor). Replacing them is important because disturbing the seal can cause leaks, even if the parts were reassembled correctly.

The AC evaporator is the heat-absorbing part inside the dashboard. As refrigerant flows through it, it evaporates and cools the air that the blower pushes through the vents.

The AC condenser is the heat-releasing component mounted in front of the radiator. After the refrigerant leaves the evaporator, the condenser cools it down so it can return to the compressor and keep the cycle going.

A common AC failure pattern is a refrigerant leak: the system loses refrigerant over time. If a shop only refills (“charges”) the system without locating and repairing the leak, the AC will stop working again shortly afterward.

The Kia Soul is a compact, boxy crossover/hatchback from Kia, known for being practical and easy to live with. In this segment, the host focuses on keeping a 2019 Kia Soul healthy by staying on top of oil changes and monitoring oil level.

Transmission fluid is the lubricant and hydraulic fluid that helps an automatic (or some manual) transmission shift smoothly and protect internal parts from wear. Changing it at the right interval can help the transmission run cooler and last longer.

Hyundai is a major automaker whose vehicles are discussed here alongside Kia. The host claims there’s a known pattern of oil consumption on some Kia/Hyundai engines and emphasizes frequent oil changes to improve longevity.

Engine oil consumption means the engine uses/burns oil as it runs, so the oil level drops between changes. The host claims this is a known issue on some Kia/Hyundai engines and ties it to a bigger risk of engine failure.

A class action lawsuit is a legal case where many people with similar claims join together against a company. Here, it’s referenced as evidence that certain Kia/Hyundai engines have a recurring problem related to burning oil.

Oil level is the amount of oil in the engine, typically checked with a dipstick or sensor. The host recommends checking it between oil changes so you can catch oil consumption early before it becomes dangerous.

Engine lock up means the engine can seize and stop rotating, usually due to severe internal damage or lack of lubrication. The host links oil consumption to this worst-case outcome, implying that low oil levels can lead to catastrophic failure.

An oil change replaces the engine oil (and usually the oil filter) to remove contaminants and keep the oil’s lubrication and cooling working properly. The “interval” is how many miles or time pass before the next change, and it varies by manufacturer and driving conditions.

Suspension parts are the components that connect the wheels to the car’s body and control ride quality and wheel contact with the road. Worn suspension components can affect handling, braking stability, and tire wear.

Coolant is the fluid that carries heat away from the engine to prevent overheating. It’s typically maintained on a schedule (often involving inspection and periodic replacement), and it works alongside the radiator and thermostat.

Brake fluid is the hydraulic fluid that transfers force from the brake pedal to the brake calipers or wheel cylinders. Over time it can absorb moisture, which can reduce braking performance and contribute to corrosion.

Power steering helps the driver turn the wheel with less effort by using an assist system. Some cars use hydraulic power steering, while others use electric power steering (EPS).

The oil light is a dashboard warning that indicates low oil pressure or an oil-related problem. If it comes on, it can mean the engine isn’t getting enough lubrication, and continuing to drive can cause severe engine damage.

Oil consumption is when an engine uses oil faster than expected, often because oil is being burned or leaking past seals/rings. The hosts describe cars arriving “with no oil in them,” which implies severe consumption and a risk of engine damage if the oil level drops too low. Regular checks and timely oil changes are emphasized as the practical mitigation.

Engine oil viscosity is the measure of how thick or thin the oil is at operating temperatures. The numbers in grades like 10W-30, 15W-40, and 0W-8 indicate how the oil behaves when cold (the “W” part) and when hot (the second number). Thinner oils can flow more easily, but if the engine’s sealing isn’t right, they may also contribute to oil getting past internal seals.

Toyota is referenced as an example of how modern engines and oil specs have changed over time. The speaker contrasts older oil grades (like 10W-30 and 15W-40) with newer, thinner oils, using Toyota’s current lineup as the backdrop for the “thinner oil” argument.

Honda is named as one of the brands the speaker recommends for reliability. In this segment, it’s part of a short list (Honda, Toyota, Mazda) presented as “the three brands” they’d suggest to buyers.

Mazda is included in the speaker’s recommended trio (Honda, Toyota, Mazda). The segment frames Mazda as a brand that “flies under the radar” but is not associated with the problems the speaker says they see in their shop.

“Low maintenance” is a practical ownership claim meaning the car typically doesn’t require frequent or complicated repairs beyond routine service. In this segment, it’s tied to the host’s experience that they rarely see major engine or transmission problems on these vehicles.

“Engine failure” refers to a serious malfunction where the engine can’t operate correctly and may require major repair or replacement. The host is contrasting this with their experience that they don’t see it often in Mazda vehicles.

“Transmission issues” means problems with the gearbox that can affect shifting, acceleration, or drivability. In this segment, the host says they don’t commonly see major transmission failures in Mazda cars.

The Mazda CX-5 is a compact SUV, and the host is using it as an example of Mazda’s smaller-SUV lineup. They describe it as being about the same size as other compact crossovers and say it’s a nice, low-hassle choice.

The 2018 Chevrolet Equinox is a modern compact SUV that uses an engine management system to control things like valve timing. When the host hears ticking and later sees an engine light tied to VVT, it points to an issue in the engine’s variable valve timing control or related sensors.

VVT (variable valve timing) is a system that changes when the engine’s intake and exhaust valves open and close. That lets the engine improve efficiency and power across different speeds, but it also means VVT-related faults can trigger an engine light and cause abnormal noises if components or sensors fail.

Camshaft and crankshaft position sensors tell the engine computer exactly where the camshaft and crankshaft are in their rotations. If either sensor fails or sends incorrect signals, the car can mis-time valve events (including VVT) and illuminate the engine light.

Intake and exhaust solenoids are electrically controlled valves that help operate the hydraulic/electronic mechanisms behind variable valve timing. If a solenoid sticks or fails, the VVT system may not adjust properly, which can cause ticking noises and set diagnostic trouble codes.

The oil filter traps contaminants in the engine oil. If metal shavings appear in or around the oil filter, it can indicate internal wear or a component failure that’s sending debris through the lubrication system.

The “engine light” is the check-engine indicator, which turns on when the car’s computer detects a fault. It’s tied to diagnostic trouble codes (DTCs) that can point to the system causing the issue.

“Reduced” here is part of a dashboard message that indicates the car is limiting performance to protect the engine or emissions systems. It’s commonly triggered when the car detects a fault and goes into a protective “limp” mode.

A vacuum pump creates vacuum pressure used by various engine systems (often including brake assist and emissions-related controls, depending on the vehicle). Replacing a failed vacuum pump can be necessary if it’s causing faults or contributing to abnormal operation.

“Reset the code” means clearing the diagnostic trouble code(s) stored in the car’s computer after a repair. If the underlying problem is truly fixed, the light should stay off; if not, the code will often return.

To “advance” or “retard” timing means shifting when the camshaft events occur relative to the crankshaft. Advancing timing generally increases cylinder pressure earlier in the cycle, while retarding delays it—both are used to match conditions like load and RPM.

The GMC Safari is a full-size van (by GMC) that’s known in enthusiast circles for being a practical, family-hauler platform—often with older V6/V8-era powertrains depending on year. In this segment, the hosts are discussing a timing-related issue on a GMC Safari, pointing to the engine’s variable valve timing and timing chain system.

Trouble codes are fault codes stored by the engine’s computer (ECU) when it detects abnormal sensor readings or component behavior. Reading them helps pinpoint whether the issue is related to timing, VVT actuation, or other engine control problems.

Clearing trouble codes resets the ECU’s stored faults, but it doesn’t fix the underlying mechanical or sensor problem. If the root cause remains (like timing being out of sync), the codes typically return after the next drive cycle.
