Keep Your Vehicle on the Road Longer: Coolant Leaks, Transmission Service, Batteries, and Brakes

Watch Now

In this episode of the C&C Auto Show, Aaron Clemus and Jamie Bridges tackle real-world maintenance questions that can make the difference between a dependable ride and an expensive surprise. The conversation covers high-mileage coolant loss and “extra vapor” from the tailpipe, when a product like K-Seal may be worth trying, and why following directions matters.

They also break down why transmission fluid exchanges are still a smart preventive move on many vehicles, how heat destroys fluid over time, and why modern brake rotors are often “replace, not resurface.” Plus: battery maintainers for vehicles that sit, DIY brake-clean tips, and a practical take on headlight upgrades.

Listen or watch the embedded episode to hear the full calls, the shop-tested advice, and the stories behind the tech tips.

Questions and Answers

Quick takeaways from this episode—coolant leaks, transmission service, batteries that sit, brake jobs, and lighting upgrades.

What are the signs coolant might be getting into a cylinder?

Extra-heavy white exhaust on startup plus gradual coolant loss are common clues. If coolant is entering the combustion chamber, it’s important to evaluate the engine’s overall condition before deciding on a full repair or a stop-leak option.

Is K-Seal a good option for a high-mileage coolant leak or suspected head gasket issue?

For very high-mileage vehicles where a full head gasket repair may not be practical, K-Seal was discussed as an option some listeners have successfully used. Following the product instructions exactly is critical, and it’s generally viewed as a way to extend usable life rather than a permanent fix.

After adding K-Seal, how long should you drive the vehicle?

The recommendation was to drive the vehicle about 30–40 minutes after adding it so the product can circulate fully through the cooling system. Always allow the engine to cool before removing a radiator cap to avoid burns from hot coolant or steam.

Should you do a transmission fluid exchange, and when?

The show strongly supported transmission fluid exchanges as preventive maintenance. A general guideline discussed was around 40,000–60,000 miles depending on the vehicle and driving habits, since heat and wear break down fluid over time.

Why does heat matter so much for transmission fluid life?

Higher transmission temperatures accelerate fluid breakdown and reduce its ability to lubricate and protect internal components. As fluid degrades, it loses its cooling and friction-control properties, increasing long-term wear.

Why should vehicles that sit use a battery maintainer?

Vehicles like boats, motorcycles, and seasonal cars can slowly drain their batteries even when turned off. A battery maintainer keeps the charge at a healthy level and helps prevent repeated dead-battery replacements.

What battery maintainer was mentioned on the show?

The Clarios D400 Plus was highlighted as a charger and maintainer compatible with AGM, flooded, and lithium batteries, allowing flexibility across different types of vehicles and equipment.

Why are brake rotors often replaced instead of resurfaced?

Modern rotors are typically manufactured thinner to reduce vehicle weight. Because they wear along with brake pads and may not have enough material to machine safely, replacement is often recommended when installing new pads.

What should you do before installing new brake rotors?

New rotors usually have a protective oil film to prevent rust during storage. Cleaning them before installation and ensuring slide pins and hardware are free of buildup helps ensure smooth, proper brake operation.

Are LED headlight bulbs a good upgrade for older vehicles?

Caution was advised with LED conversions. Some kits are not truly plug-and-play and may cause beam pattern issues or early failures. Trying high-quality upgraded halogen bulbs and ensuring the headlamp lenses are clear may provide noticeable improvement first.
