Why and When to Replace Your Cambelt

Your cambelt, also known as a timing belt, plays a crucial role in the proper function of your vehicle’s engine. However, knowing what a cambelt is and when it needs to be changed is important. In this blog post, we’ll explain the importance of timely cambelt replacement, why it’s so important to have it regularly checked, and the signs for cambelt replacement.

What Is a Cambelt and How Does It Work

Your vehicle’s engine is made up of many pieces of metal that move about several thousand times a minute. One of those components is the cambelt. It’s a component that synchronizes the rotation of the crankshaft and the camshaft, ensuring that the engine’s valves open and close at the right times.

Why Replace Your Cambelt

Regular cambelt replacement is essential for the smooth operation and longevity of your vehicle’s engine. As the cambelt ages, it can become cracked and cause the belt to fail without warning. In some cases, when the engine is idle, a rattling noise can be heard coming from the timing belt area. By adhering to your car maintenance schedule and replacing your cambelt at the recommended intervals, you can prevent costly engine repairs.

When to Replace Your Cambelt

Determining when to replace your cambelt depends on several factors, including your vehicle’s mileage, age, and the manufacturer’s recommendations. Most manufacturers recommend replacing the cambelt between 60,000 to 100,000 miles or every 5 to 7 years – whichever comes first. Additionally, if you notice any signs of wear within the engine, get an engine diagnostic. There might be other components that need care.

Signs It’s Time to Replace Your Cambelt

There are several warning signs indicating that it’s time to replace your cambelt. Oil leaking from the front side, check engine light is on, or the engine is misfiring while driving, may signal a worn-out cambelt that needs immediate attention. Regular inspections and maintenance checks can help identify these issues early on and prevent potential engine damage caused by a worn or broken cambelt.

The Role of Oxygen Sensors in Your Vehicle’s Performance

Most vehicle engine control systems rely on input from oxygen sensors to regulate the engine’s performance as well as its emissions and other vital functions. However, oxygen sensors can deteriorate over time, and as a result, you may experience increased fuel consumption, driveability problems, emission failures, and other problems. In this month’s blog, we will explore when and why you should consider replacing your car’s oxygen sensor.

When to Replace Your Oxygen Sensor

Oxygen sensors typically have a lifespan of around 30,000 to 50,000 miles, but this can vary depending on various factors such as driving conditions and vehicle maintenance. However, there are certain signs that indicate it may be time to replace your oxygen sensor. One common indicator is a decrease in fuel efficiency. A faulty oxygen sensor can lead to an incorrect air-to-fuel ratio, resulting in poor gas mileage. Additionally, if your car is experiencing a rough idle, engine misfires, or has reduced power, it could be a sign that the oxygen sensor is not functioning properly. Lastly, if your vehicle’s check engine light is illuminated, it is essential to have the oxygen sensor checked as it could be the culprit.

The Importance of Timely Replacement:

Replacing a worn-out or malfunctioning oxygen sensor is crucial for maintaining your car’s performance and fuel efficiency. A faulty sensor can result in inaccurate readings being sent to the ECU, leading to a misbalance in the air-fuel mixture. This, in turn, can cause the engine to run rich or lean, affecting not only fuel efficiency but also the overall performance of your vehicle. Moreover, a failing oxygen sensor can lead to increased wear on other engine components, such as the catalytic converter. Therefore, it’s essential to address any issues with your car’s oxygen sensor promptly.

Warning Signs You Should Get an Engine Diagnostic

A seasoned driver quickly catches what is wrong with their ride in an instant. Sometimes, it is really hard to pinpoint the exact issue because one symptom could mean countless things. For example, the burning smell of rubber can be worn-out tires or a broken belt. The car vibrating could be a problem with the transmission or wheel alignment. Here are some warning signs you should get an engine diagnostic test to identify any malfunctions.

1. Your tailpipe is emitting an unusual amount of smoke.

Steam coming out of your car tailpipe is very common, especially in the cold weather, but if you see black smoke emitting from your tailpipe, it is high time you get an engine diagnostic test. Colored smoke coming out of your tailpipe is never a good sign, so this needs to be diagnosed as soon as possible to prevent further damage to your engine.

Squealing brakes are a definitive indicator of failing brakes, but there are some sounds that even a professional can’t figure out. For example, a rattling sound coming from the engine could mean many things. That is why it is advisable to go for an engine diagnostic test to detect the real problem that is causing strange noises.

3. Your car electronics are not working properly.

Finding the cause of your electronics’ malfunction might be challenging because it could be anything from your alternator to your battery to your computer system. Your dealership’s factory-trained expert can use their diagnostic equipment to figure out why your electronics aren’t working correctly. To maintain your car running at its peak, they will also be able to repair or replace the problematic parts with authentic manufacturer components.

Strange smells are never a good indication of your car, but occasionally you can identify where they are originating from. For instance, if you’re braking hard while traveling down a steep hill, the brakes may overheat and emit a burnt odor. However, you might detect gas or other unidentified odors on different occasions.

4 Signs Your Car’s Engine Needs Maintenance

The engine is the beating heart of the car; it gives the necessary strength for proper performance and keeps the vehicle in good condition. However, this critical part is not always invincible! With less maintenance, the engine will be damaged and directly affect your vehicle’s performance. Fortunately, this can be easily avoided by giving the engine the attention that it needs and regular inspections from time to time.

In this month’s blog, we will discuss some of the most critical signs of car engine damage that require checking and repairing as soon as possible.

Check Engine Light

There are many different engine problems and malfunctions that can cause the check engine light to light up. The most important of which are:

  • There is a malfunction in the oxygen sensor and it needs to be replaced.
  • The adapter is damaged and it needs to be replaced.
  • The fuel cap is loose, and fortunately, it’s an easy problem to fix.

Knocking Noise

This often occurs as a result of damage to mechanical parts in the engine, such as the pistons or other moving parts that stop working. Your car in this case, will likely require a massive engine repair or possibly even an engine replacement.

Thick Exhaust Smoke

Whether it’s a thick gray, blue or black smoke, a colorful smoke usually indicates that there is something wrong with the engine that requires treatment as quickly as possible. This can include a malfunction in the fuel injector, sensors, air filter, a blockage in the fuel passage, or mechanical damage to the engine.

High Fuel Consumption

If you’re noticing that you are filling up your car’s gas tank more often than normal, chances are there is a malfunction in the engine. This sign indicates that the components that process the car fuel inside the engine are damaged, and this problem is usually also indicated with a check engine light.

The best thing you can do to notice this problem quickly is to keep track of how many miles you get per gallon. You don’t need to track it with exact numbers, but a general idea is enough to know when it’s time for a new engine or checkup.


Many car owners may eventually need to change the engines of their cars due to minor or major problems that might occur and affect the vehicle.

Car Diagnostic: The Details

If your car is acting up, you could take it into a repair shop for a total vehicle inspection, but there is an easier way to troubleshoot. The “check engine” light and other misfires can indicate a wide range of issues that can be difficult to determine. An auto diagnostics test will investigate the computer system in your car, and reveal any problems going on quickly and accurately. To learn more about the specifics of an auto diagnostic test, keep reading this blog post.

The Process

Once you take your vehicle in to the dealership or repair shop, a certified mechanic will link a car diagnostic computer to your vehicle’s computer processor, sensors, and microchips. This process takes just a few minutes, rather than the hours needed to perform a total car inspection. The convenience of the auto diagnostic makes it a necessity when your car is off-kilter.

The History

Back in the year 1996, the Environmental Protection Agency established that all cars sold in the United States must use the same diagnostic systems so repair shops can diagnose all vehicles regardless of the make and model. The diagnostic test that was created does a total-vehicle checkup, responding to a set of codes that signal what the mechanic must focus on.

What Does it Detect?

A simple auto diagnostic will tell you a number of things about your car. For example, it will indicate whether it has ignition timing issues, buildup in the engine, engine RPM inconsistencies, and coolant levels. The mechanic can also look for manufacturer notes and other vehicle history information during the scan, which will allow them to tailor repairs to your car’s needs. During the diagnostic exam, the computer will reveal a report with codes that indicate areas that need repair. Since the test will notify you of minor issues, you will be able to avoid future costly repairs.

How Often?

Professionals recommend that people perform annual checkups on their vehicles to ensure their proper function. Once it’s been a year, you should head on in to the auto shop to be safe. Even if you don’t notice any present issues with your vehicle, there could be minor problems with the exhaust system, transmission, brakes, or more that could lead to major future damage. Get ahead of the problem with annual checks.


There is nothing easier than taking your car in for a diagnostics check, which takes only an hour or two. To keep your car in great shape for longer, make sure you get it done every year. If you’re in Del City, OK come on in to H.W. Automotive Inc the next time you’re ready for auto repairs.
