![]() ![]() A broken radiator cap is one of the quickest fixes any vehicle owner can perform confidently (remember, never open the radiator cap when the engine is hot-always wait until the radiator is cool to the touch). If you’re lucky, fixing a coolant leak in your sedan, pickup, minivan or SUV is as simple and straightforward as replacing a minor part. Now that you know the signs of a coolant leak, let’s dive into what is likely causing the coolant leak. What Causes a Coolant Leak & How to Fix It In a worst-case scenario, you will see visible steam clouds coming from under your hood while your engine is running due to the intense heat radiating from the engine compartment. A clear (or should we say neon) sign that you have a car leaking coolant is orange, green, red or blue liquid forming on the ground beneath your frontend. For more classic cars and old-school pickups, you should monitor the temperature gauge on your dash to ensure the red needle isn’t steadily rising toward the red danger zone. In most modern vehicles, the ‘check coolant level’ warning light will illuminate on your dashboard. If there isn’t enough liquid circulating, your interior cabin won’t heat up in the winter. When set to heat, your A/C system relies on warm coolant from the engine passing through the heater core. So, what are the signs of a car leaking coolant? If your heater is blowing cool air through the vents, you could have a low coolant problem. A blown head gasket is just one example of how one damaged automotive part can lead to expensive service repair bills if left unaddressed. A leaky head gasket means this critical component is warped, which allows coolant to escape into the engine’s combustion chamber. If your coolant is contaminated, dried up or leaked out, your high-powered engine will ‘melt down’ from extreme heat and pressure. It lubricates the water pump and carries important additives, which prevent corrosion from forming inside the engine. Coolant is critical for maintaining efficiency and even improving performance. ![]() This automotive liquid transfers the heat from inside your engine to your radiator where it is then further dispersed. Offered in a spectrum of formulations and colors, the coolant running through your engine’s operating system keeps temperatures regulated. ![]()
