Things To Know About Antifreeze Leaks

Modern car engines can generate so much heat, they could potentially destroy themselves if not for the help of a liquid cooling system. By circulating cooling fluid throughout the engine, the engine is kept cool, and excess heat is carried out of the engine. Naturally, that means if this system leaks fluid, the engine is at risk of overheating, which has the potential to cause catastrophic damage! Below, we'll tell you about four places the engine cooling system could leak and why.

Coolant is often brightly colored so that it's more easy to spot a leak 

4. Radiator Leaks

When you imagine the kind of coolant leak that leaves a big puddle under the front of your car, that's possibly a leak from the radiator. Once the coolant captures excess heat from the engine block, it flows to the radiator where air can flow across the radiator and cool the fluid back down as you drive. Since the radiator is typically located right behind the vehicle's front grille, the radiator is easily damaged in a forward collision. The system of delicate fins can more easily be damaged by rust or corrosion build-up, which can also lead to a leak. Coolant is typically bright green, pink or orange in color. If you notice such a puddle forming beneath your car, get a tow to our service center where we can check your radiator and repair or replace it.

3. Engine Leaks

While you might be able to spot coolant puddles forming under your car if the leak is big enough, some smaller leaks might not be so easy to spot. For example, coolant has to flow through all parts of the engine. If one of the engine's seals fails, such as the head gasket, coolant can seep out of the engine, burning up and congealing on the engine's exterior before a puddle can form. In fact, coolant leaks can even form inside the engine, causing coolant to be burned up by the engine. Sometimes, this can cause your car to emit a white exhaust smoke as you drive. If your engine begins to overheat, find out why and get it repaired before the engine can sustain damage. If there's a coolant leak or a blown gasket, we'll help you get it fixed.

2. Hose Leaks

If the components that make up your cooling system aren't themselves leaking, you might have a leak in the hoses the coolant flows through. Between the engine and the radiator, the water pump, the heater core and other elements are durable rubber hoses. They're held in place by metal clamps. If any of the fittings come loose, or a hose sustains damage -- such as rubbing against a moving part, drying out and rotting or cracking -- coolant may begin to leak. As part of a cooling system inspection, we'll check all the fittings and connections in the system to make sure they're in good shape.

1. Heater Core Leaks

The heater core is essentially another radiator, but it's located behind the dashboard as part of the vehicle's climate control system. When you turn the heater on, hot coolant from the engine flows to the heater core, which warms the air before it's sent through the climate system vents. The heater core may similarly develop a leak, and when it does, it might even leak coolant down the back of the dashboard and into the vehicle's interior, usually the passenger's footwell. Coolant has a sweet, syrupy smell, so if you find a mysterious leak of a sweet-smelling substance in your car, now you know where it (probably) came from.
