Why does my car only leak coolant sometimes?

Why does my car only leak coolant sometimes?

A coolant/antifreeze leak can occur for a variety of reasons, including a blown radiator hose, a bad hose clamp, warped head gasket, or the most common reason, a foreign object kicked up by the truck in front of you penetrating the radiator itself.

Why does my antifreeze keep getting low?

Causes of Coolant Loss External leaks from radiator hoses, connections between hoses, or from the radiator itself. Radiator cap leaks due to a faulty seal on the cap where the pressurized coolant can leak out. Internal leaks where coolant may leak out of places such as the engine’s head gasket.

Why do I have to keep replacing my coolant?

The coolant can become more acidic over time and lose its rust-inhibiting properties, causing corrosion. If the corrosion inhibitors have deteriorated, the antifreeze coolant should be changed.

How do I find out where my coolant is leaking from?

Look for signs of coolant leakage—a light-colored residue or stain—around the radiator cap, on hoses throughout the engine compartment (check the ends where they are clamped to other components) and on the radiator itself. If it looks like a hose is leaking near a clamp, try tightening the clamp with a screwdriver.

What happens if you don’t replace engine coolant?

The answer: nothing good. Coolant circulates through your car and extracts heat from various components, keeping their operating temperature within normal parameters. Without coolant, there’s nothing to extract this heat, and these parts quickly overheat and break down.
