Disappearing engine coolant could be the result of a slightly cracked hose, a tiny hole in your radiator, or a water pump issue. It's also possible for a coolant leak to develop inside your vehicle or to simply vaporize into mist via your defroster.
Where is my antifreeze going if it's not leaking?
If you've ruled out an internal leak, that means your engine is burning the coolant somewhere else. The most common place is the radiator cap. Radiator caps hold the pressure inside the system, but if it's not sealing properly, then some hyper pressurized coolant will escape in the form of steam.
Can coolant leak without a leak?
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.
Why is my coolant running out so fast?
Antifreeze leaks can be caused by a variety of things but the two most common factors are age and dirty coolant. Dirt or oil in your coolant can accelerate wear in your system, leading to leaks in your water pumps, at gaskets, or at o-rings. Flushing your cooling system is the best way to stop this type of leak.

How do I find a leak in my radiator?
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.
How do you know if your water pump is going bad in your truck?
One telltale sign of a soon-to-be-faulty water pump is a noticeable coolant leak toward the front of the vehicle. If the car is left overnight and you notice an orange or green (depending on the coolant you use) puddle on the ground, suspect the pump.
How does coolant run out?
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.

Can a water pump be bad and not leak?
It is usually driven by a belt from the crankshaft pulley or sprocket. The answer to the question of whether a water pump can be bad and not leak is yes. Some modern water pumps have plastic impellers (fan blades) and these sometimes break. This leads to vibrations which in turn cause the pump to fail.
What does a water pump sound like when it's going bad?
Whining or Groaning Noise A whining or groaning noise usually means that either a drive belt is loose, or the water pump pulley is bad.
Will a bad water pump throw a code?

How do I know if my car water pump is working?
With the engine off, open your hood and locate the water pump pulley. With gloves on, grab it and wiggle it back and forth. There should be no movement, if there is, this along with the noise is a good indication you may have a water pump problem.
Will check engine light come on for blown head gasket?
your check engine light is on: the car's computer constantly monitors engine performance. if it detects a misfire caused by a leaking head gasket, it turns on the check engine light.
How much does it cost to fix a head gasket?
How Much Does it Cost to Replace a Head Gasket? According to a national average, it costs between $1,624 and $1,979 for a head gasket replacement. The associated labor costs are estimated between $909 and $1147 while the parts themselves vary in the range of $715 and $832.
How much does a blown head gasket cost to fix?
How much does it cost to replace a blown head gasket? The cost of head gasket repairs can run into the thousands, meaning it's often easier and cheaper to scrap the vehicle than it is to have it repaired. The average cost of head gasket repair is around $1,000 to $2,000, but this isn't because the parts are expensive.
How often should engine coolant be topped up?
You need to check your engine coolant at least twice a year before summer and winter, ideally. Although, this advice may vary between car manufacturers. Coolant should be topped up whenever the level drops below the guide marks.
How much coolant loss is normal?
How much coolant loss is normal? Providing that the engine is running well, with no leakages or damage, you can expect a coolant loss of 0.25% every four to six months. This means a loss of two to three ounces a year is completely normal.
Should I add coolant to radiator or reservoir?
If your engine is cold, the coolant level should be up to the cold fill line. Loosen the reservoir cap just a little, then step back while the pressure releases. Then, remove the cap completely. If the coolant level is low, add the correct coolant to the reservoir (not the radiator itself).
