The Ultimate Guide to Transmission Repair: Keeping Your Vehicle Running Smoothly

When you start your car and head out on the road, there's a lot happening under the hood that most drivers never think about. One of the most important parts working behind the scenes is the timing chain. While it might not get the psotlight like brakes, tires, or batteries, it plays a critical role in keeping your engine running smoothly. What Is a Timing Chain? A timing chain is a strong metal chain inside your engine that connects the crankshaft and camshaft(s). Think of it like the conductor of an orchestra- it makes sure all the engine's moving parts stay in perfect rhythm. The pistons and valves have to move at exactly the right time, and the timing chain makes that hapeen. Without it, the engine simply wouldn't run. Do All Cars Have Timing Chains? Not all cars use a chain. Every enegine needs a timing system, but some manufacturers use a timing chain (metal) while others use a timing belt (reinforced rubber). Both do the job, but chains generally last longer, while belts need replacement sooner. Why Is The Timing Chain So Important? The timing chain ensures precision inside your engine. If it stretches, skips, or breaks, the engine's timing is thrown off- and that ca lead to serious and costly damage like bent valves, piston damage, or even complete engine failure. In other words, when the chain fails, it can take the whole engine with it. How Long Do Timing Chains Last? One of the benefits of a chain over a belt is lifespan. Timing chains are designed to last a very long time- often 150,000-200,000 miles, and sometimes for the entire life of the vehicle. That said, they aren't invincible. The chain itself can stretch, and the guides or tensioners that keep it tight can wear down over time. Maintenance and Warning Signs Timing Chains are lubricated by engine oil, so the best way to take care of them is by keeping up with regular oil changes. Dirty or low oil can speed up wear and tear. Some common warning signs of timing chain touble include; -Rattling noises from the engine, especially at startup, -A check engine light, -Rough idling or misfiring. If you notice these symptoms, it's a good idea to have your vehicle inspected before the problem turns into something bigger. Why Do Timing Chains Need to Be Replaced? Eventually, even tough metal chains wear out. they can stretch, lose tension, or their guides can fail. Replacing a timing chain isn't cheap, but it's still much less expensive than repairing or replacing an engine after the chain has failed. The Bottom Line Your timing chain might not be something you think about often, but it's one of the hardest-working parts of your engine. With regular oil changes and good maintenance habits, it can last for years without trouble. But keeping an ear out for warning signs- and addressing them early-can save you from major engine damage down the road.

A heater core is a small radiator-like component inside your vehicle, usually located behind the dashboard. It is part of your car's cooling system and heating system. It looks like a mini radiator, with tubes and fins, and it carries hot coolant from the engine. When the temperatures drop, most drivers don’t think twice about turning the heat on in their car. But behind that blast of warm air is a hard-working little part called the heater core. Understanding what it does and why it’s important can help you spot issues early and keep your car comfortable and safe. How does it work... your engine produces heat while running, and coolant circulates through the engine and absorbs that heat. Some of that hot coolant is routed into the heater core. A blower fan pushes air across the heater core's hot fins; in turn, the warm air is sent through your vents and into the cabin. So every time you turn your heater or defroster on, you're relying on the heater core to deliver that heat. Why the heater core matters... The heater core is more than just a comfort feature- it plays several key roles. It keeps you warm during cold weather. It directs warm air to your windshield to clear fog and ice for better visibility. The heater core regulates engine temperature by pulling heat from the coolant, preventing your engine from running too hot. Like any other car part, the heater core can wear out or leak over time. Be sure to watch for these symptoms: foggy windows inside the car, a sweet smell (from coolant) inside the vehicle, coolant leaking onto the passenger-side floor, no heat, or weak heat coming from the vents, and or engine overheating caused by low coolant levels. Why you shouldn't ignore heater core issues... A faulty heater core isn't just uncomfortable- it can leave you stranded. If it leaks, you'll lose coolant, which can cause your engine to overheat and lead to serious engine damage. Plus, driving without a heater or a working defroster is a safety risk in winter conditions. The heater core may be small, but it plays a big role in keeping your car safe, comfortable, and reliable. If you notice signs of heater core problems, it's best to have it checked out right away before it turns into a bigger repair. Check out our video on YouTube: https://youtu.be/qnsqRA0J9hI

Understanding Airbags: How They Keep You Safe on the Road When it comes to vehicle safety, airbags are one of the most important features your car has. Most of us know they “pop out” in a crash, but have you ever wondered how they actually work—or why they're so important? At Faithful Auto and Truck Repair, we believe informed drivers are safer drivers. Here’s a simple breakdown of how airbags protect you and your passengers. What Are Airbags? Airbags are soft, fabric cushions that inflate in a split second during certain types of collisions. Their job? To absorb impact and reduce injury by acting as a buffer between you and the hard surfaces in your vehicle—like the steering wheel, dashboard, and windows. How Do Airbags Work? Your car is equipped with sensors that detect sudden stops or crashes. If the impact is severe enough, those sensors trigger the airbag system. A tiny explosive charge fills the airbag with gas (usually nitrogen or argon) in just milliseconds. Sensors Detect a Crash: Your vehicle has crash sensors that monitor sudden deceleration (like in a collision). Signal Sent: If the impact is severe enough, the sensors send a signal to the airbag control unit. Inflation: The airbag system ignites a small explosive charge that rapidly fills the airbag with a gas (usually nitrogen or argon) in about 0.03 seconds. Cushioning Effect: The airbag inflates to create a cushion between you and hard surfaces like the steering wheel, dashboard, or windshield. Deflation: Right after inflation, the bag deflates through small vents to absorb the energy of your body and allow movement. Once deployed, the airbag cushions your body, especially your head, neck, and chest. After doing its job, it deflates quickly through small vents—reducing the risk of rebound injuries. Types of Airbags in Today’s Vehicles Modern vehicles have multiple airbags placed throughout the cabin: Front Airbags – For the driver and front passenger. Standard in all cars since 1999. Side Airbags – Built into doors or seats to protect your torso in a side impact. Curtain Airbags – Drop down from above the windows to protect your head. Knee Airbags – Help prevent leg injuries in a frontal crash. Rear Airbags – Found in some newer models to protect backseat passengers. Airbags + Seat Belts = Maximum Safety One of the biggest safety misconceptions is that airbags replace seat belts. Not true! Airbags are designed to work with seat belts—not take their place. Without a seat belt, the force of an airbag alone can actually cause more harm than good. Always buckle up. Maintenance Tips While airbags don’t require regular maintenance, it's still a good idea to: Check your dashboard for the airbag warning light—if it's on, something's wrong. Have your airbag system inspected after an accident, even if it didn’t deploy. Keep kids under 13 in the back seat with proper restraints. Another important safety tip people often don't think about...Keep your feet off the dash while the vehicle is moving. The airbag can deploy upwards to 200mph. At Faithful Auto and Truck Repair, we care about more than just keeping your car running—we want to keep you and your family safe. If your airbag warning light is on or you’ve recently been in an accident, stop by and let us take a look. We’re happy to answer any questions and give you peace of mind.
