Your vehicle’s cooling system plays a critical role in regulating engine temperature and preventing overheating. When any part of the system begins to fail, it can quickly lead to serious engine damage. That’s why it’s important to recognize the early signs of cooling system trouble and address them right away. At Hye-Tech Auto, we provide expert cooling system repair in the greater Covina, CA area. Here are four signs that your vehicle’s cooling system needs immediate attention.

Rising Temperature Gauge

One of the most obvious indications of cooling system trouble is a rising engine temperature gauge. If you notice the needle climbing toward the hot zone, especially during normal driving conditions, it’s a clear warning sign. This could indicate problems like low coolant levels, a failing thermostat, or a problem with the radiator. Continuing to drive with an overheating engine can cause severe internal damage, so it’s crucial to stop and address the issue as soon as possible.

Steam from Under the Hood

If you see steam coming from under your hood, it's a strong sign that your engine is overheating. This commonly happens when coolant is boiling and turning to vapor, often due to a leak. Pull over immediately if you notice steam, and avoid opening the radiator cap while the engine is hot. Letting a mechanic inspect the system ASAP can help prevent further damage.

Coolant Leaks

Visible coolant leaks are a serious red flag. You might spot bright green, orange, or pink fluid (yours could be a different color) under your vehicle. Leaks can occur from the radiator, hoses, or water pump. Even small leaks can soon deplete coolant levels, leading to overheating. If you notice a puddle, it’s important to have the cooling system inspected before driving any further.

Low Coolant Light 

Many modern vehicles are equipped with sensors that detect low coolant levels or high engine temperatures. If your dashboard displays a coolant warning light or message, don’t ignore it. These alerts are designed to prevent engine damage by giving you time to react. Topping off coolant (after your engine has cooled down) might help temporarily, but the root cause still needs to be diagnosed and fixed.
