Why is my coolant low but no leaks?

When you are losing coolant but no leak is visible, several parts could be the guilty party. It could be a blown head gasket, a fractured cylinder head, Damaged cylinder bores, or a manifold leak. It could also be a hydraulic lock.

Overheating under the hood.

Smoke blowing from the exhaust with a white-ish tint.

Depleted coolant levels with no trace of leakage.

Bubble formations in the radiator and overflow compartment.

Milky discoloration of the oil.

How long can you drive on an overheated engine?

Someone may hit up to 20 miles with an overheating car, and the engine would still be in good condition. In contrast, another may hit just 10 miles, and the car might shut off on its own. This is to prove that there is no length or mileage that an overheating engine would drive before a potential/fatal damage occurs.

How much should coolant cost?

The cost of a coolant flush typically runs between $100 and $150, according to highly rated mechanics. Kauffeld says this can include four gallons of coolant, a conditioner and a cleaner.

How long does coolant last in a car?

Depending on the vehicle and the coolant, the average time between flushes is two years or 30,000 miles for silicated coolants and up to five years or 100,000 miles for an extended drain coolant. You can tell which type of coolant you have by the color.
