The pressure will eventually be enough to force coolant through the tiny hole and your car will slowly lose coolant. As you drive, pressure in the cooling system will build. You will often see a pinpoint leak that only sprays coolant when the car is warmed up.Ī hose with a small hole may actually seal just fine when the car is cold. Most of the time the pressure isn’t high enough to rip the hose in half.

If pressure in the cooling system is too high, you are likely to see one or more hoses start to spray coolant all over the engine bay. 5) Radiator Hose Bursts radiator hose ready to burst If this happens, inspect the cap to see if there is any damage. The vacuum won’t be released by the radiator cap properly and it will cause the radiator hose to collapse during the cooling down period. You may have a bad radiator cap if the radiator hose collapses. While you’re in there, check to make sure your coolant overflow tank is working properly.

If you have a bad radiator cap, the coolant could get released too quickly and cause the reservoir to overflow. The radiator cap releases the extra pressure by sending some coolant into the overflow tank. 3) Overflowing ReservoirĬoolant goes into the reservoir tank as it expands. They may tell you the cap is leaking under pressure or intermittently. While you may not notice coolant leaking from under the radiator cap, look out for these white streaks. When coolant leaks out of the radiator filler neck and dries, it often leaves white streaks behind.

If you notice coolant near the radiator or the radiator cap, then you clearly have leaky coolant. If the radiator cap is stuck, pressure may build inside of the radiator, which could cause cooling system components to leak or burst. Signs of a Faulty Radiator Cap 1) Leaking Coolant
