Your vehicle’s cooling system plays a vital role in maintaining engine temperature and preventing overheating. It circulates coolant through the engine and radiator to absorb and dissipate heat. When this system starts to fail, your engine can quickly become too hot, leading to serious damage and expensive repairs. Recognizing the early signs of cooling system trouble can help you address small issues before they become major problems. At Ken’s Muffler & Brakes, we provide expert cooling system repair in the greater Dallas area. Here are four common symptoms of a cooling system issue.


Rising Engine Temperature

One of the clearest signs of a cooling system issue is a rising temperature gauge on your dashboard. If it starts creeping into the hot zone, your system may not be circulating coolant properly. This could be caused by issues like a failing water pump, low coolant level, or a blocked radiator. Continuing to drive with a hot engine can lead to severe engine damage, so it’s best to pull over and let the engine cool down before investigating further.


Coolant Leaks Under the Vehicle

If you notice bright green, orange, or pink fluid (yours could be a different color) pooling under your car, there’s a strong likelihood it’s a coolant leak. The cooling system relies on maintaining proper coolant levels, and even small leaks can lead to big problems. Leaks often come from worn hoses, a cracked radiator, or a faulty water pump. It’s important to have a technician inspect and repair leaks promptly to keep your engine protected from overheating.


Sweet Smell Coming from the Engine Bay

Coolant has a distinctive sweet smell, and if you start noticing it while driving or after shutting off your car, it could mean coolant is escaping somewhere in the system. This odor can come from a small leak that isn’t yet noticeably accumulating or from coolant vaporizing on hot engine parts. Either way, it’s a sign that your system isn’t sealed properly and should be checked as soon as possible.


Steam from Under the Hood

If steam starts coming from under the hood, your engine is likely overheating. This commonly means that coolant isn’t flowing properly or that the radiator can’t cool it effectively. When this happens, pull over safely ASAP and turn off the engine to avoid serious damage. Be sure to let your engine cool before investigating the matter.

What are some simple ways to help keep my brakes healthy & safe?

by Ken’s Muffler & Brakes • 3 October 2025
Brakes are among the most critical safety components on your vehicle. When they’re in top condition, you can drive with confidence knowing you’ll be able to stop when it matters most. On the other hand, neglected brakes can become a major hazard and lead to costly repairs. The good news is that with a little preventive care and attention, you can help keep your brakes performing reliably for years to come. At Ken’s Muffler & Brakes, we provide expert brake service in the greater Dallas area. Here are four tips for healthy brakes. Get Regular Brake Inspections Having your brakes checked regularly is the first step in keeping them dependable. During an inspection, a mechanic can look for worn pads, thin rotors, or leaks in the brake lines. Routine inspections often reveal small problems before they escalate into dangerous or expensive issues. It’s generally recommended to have your brakes looked at at least once a year, or sooner if you notice anything unusual. Replace Worn Brake Pads on Time Brake pads are designed to wear out over time, but waiting too long to replace them can create bigger problems. Once pads become too thin, they can cause rotor damage that requires more extensive repairs. If you hear squealing or grinding noises when braking, it’s a strong sign your pads are due for replacement. Keep an Eye on Brake Fluid Brake fluid plays an essential role in the braking process, helping transmit pressure from the pedal to the brakes themselves. Over time, this fluid can absorb moisture, which reduces its effectiveness and may lead to corrosion in the brake lines. Checking your brake fluid level and condition periodically, and having it flushed as recommended in your vehicle’s manual, helps maintain strong and responsive braking power. Address Problems Right Away Strange sounds, vibrations, or a spongy feeling when pressing the brake pedal are all warning signs that something isn’t right. Ignoring these symptoms can compromise your safety and lead to more serious mechanical issues. As soon as you notice unusual behavior from your brakes, schedule a professional inspection. Prompt attention keeps your vehicle safe and prevents small problems from becoming major repairs.

Engine Overheating: A Look at 4 Common Causes

by Ken’s Muffler & Brakes • 10 September 2025
When your vehicle overheats, it’s more than just an inconvenience—it’s a warning sign that something under the hood isn’t functioning properly. An overheated engine can cause serious damage if not addressed quickly. At Ken’s Muffler & Brakes, we provide expert cooling system repair in the greater Dallas area. Here are four issues that often lead to an overheating vehicle. Failing Thermostat The thermostat is a small but essential component that controls the flow of coolant through your engine. If the thermostat gets stuck in the closed position, coolant cannot circulate, and heat builds up rapidly. Drivers may notice the temperature gauge rising unusually fast, signaling that the thermostat may be malfunctioning. Replacing a faulty thermostat is a relatively simple repair, but ignoring it can result in significant engine damage from overheating. Low Coolant Levels Coolant plays a critical role in keeping your engine at the right temperature. If your coolant levels are low, your car will struggle to regulate heat, especially in hot weather or heavy traffic. Leaks in the radiator, hoses, or water pump are often the culprits behind coolant loss. Without enough coolant circulating through the system, the engine cannot dissipate heat properly, which can quickly lead to overheating. Radiator Problems The radiator is responsible for cooling down the hot coolant before it circulates back into the engine. When the radiator becomes clogged, damaged, or develops leaks, it cannot perform this crucial function. A clogged radiator may be caused by debris buildup, while leaks are often the result of corrosion or physical damage. Because the radiator is central to the cooling process, problems with it can easily lead to overheating. Malfunctioning Water Pump The water pump enables coolant to flow properly throughout the engine. If the pump fails, coolant will not move efficiently, and the engine will begin to overheat. Signs of a failing water pump include coolant leaks and whining noises. Prompt replacement is necessary to prevent serious damage.
