When do you lose coolant, but no leaks?

When do you lose coolant, but no leaks?

It may be happening only when the car is hot when you drive and the coolant is under pressure. Try checking it when it is hot, under pressure and while the engine is running. BustedKnuckles July 6, 2016, 2:02am #8 The coolant pressure test is obviously showing a coolant leak. The system should not lose pressure if there were no leaks.

What causes coolant to leak from bottom of radiator?

The leak may be happening from the bottom hose or radiator drain. It may be happening only when the car is hot when you drive and the coolant is under pressure. Try checking it when it is hot, under pressure and while the engine is running.

Why is my coolant leaking but no dye marks?

It is a slow leaks about an overflow in 2 weeks and no dye marks. The leak may be happening from the bottom hose or radiator drain. It may be happening only when the car is hot when you drive and the coolant is under pressure. Try checking it when it is hot, under pressure and while the engine is running.

Can a car lose antifreeze without a leak?

Monitoring its level and condition is a part of the regular maintenance of the vehicle. Generally, there should be a leak somewhat if the vehicle is losing a high amount of antifreeze. However, a car could be losing coolant but no leak. What should you do when coolant disappearing from reservoir without leaving any trace?

What causes coolant to leak from the radiator?

A defective radiator cap gasket will allow coolant to escape in the form of steam. The steam disperses inside the engine compartment. With high engine temperatures, the steam evaporates or moisture collects on the engine compartment firewall and fender wells. Coolant loss results, without obvious puddles signs.

What happens if you lose antifreeze with no apparent leak?

Losing Antifreeze With No Apparent Leak. Whenever a vehicle loses antifreeze, also known as coolant, the usual expectation leads the owner to check for evidence of leaks at all the coolant connections and components. Obvious coolant leaks can usually be found in the form of puddles left on the pavement.

Why does coolant disappear from the engine reservoir?

Call it antifreeze, a coolant, or even radiator fluid; the purpose is to maintain the engine’s cool. There may be times when the coolant system may fail due to one reason or another. The mystery arises though when magically the coolant disappearing from reservoir is noticed with no potential signs of leakage. Has this happened with your car too?

Can a head gasket leak cause coolant to evaporate?

Solving the mystery of Coolant Disappearing From Reservoir. Sometimes, though the head gasket can turn out to be defective. Such an issue, in turn, can lead to coolant flowing into the cylinder and evaporating. In case, the head gasket leak is a minor one; the air is likely to enter the coolant system.

Is there a leak in my Malibu 2.5L?

On my 2013 Malibu 2.5l LCV I have been loosing coolant and I can’t find the leak. So far I have pressure tested the cooling system at 20 psi and found no leaks. Today I have added the dexcool friendly uv dye in hopes of the leak showing up. After letting the dye circulate for an hour or so no leaks noted.

What causes a car to lose coolant after turning it off?

Coolant loss results, without obvious puddles signs. When a vehicle overheats, or after the engine has been turned off after a long ride, an expansion valve opens inside the radiator cap to allow pressurized coolant to enter the overflow reservoir.

Is there a leak in my coolant system?

So far I have pressure tested the cooling system at 20 psi and found no leaks. Today I have added the dexcool friendly uv dye in hopes of the leak showing up. After letting the dye circulate for an hour or so no leaks noted. There are no stored DTC codes, no milky oil and no white smoke from the exhaust.

Can a coolant leak be detected at an oil change?

This is much different than the slight decrease in coolant levels that you’ll notice at regular oil-change intervals. Sometimes a leak may not be visible. Even if you have depleted coolant levels with no sign of leakage, you could still have an internal leak that isn’t detectable from the outside of your engine.

When does the coolant go out in a van?

Another test to try is to start the van and let it get real hot, then shut it off in a quiet garage or area and listen. Cooling system max pressure happens right after engine shutoff when there is no circulation to keep coolant temps more even. Any seep leaks will happen at this time.

What to do if your fridge is losing coolant?

It’s possible to have a pressure loss between the pressure tester and radiator. I’ve seen this more than a few times. You might consider wiping the connection surfaces down with a cold, heavy grease as this can help stop any pressure loss. Stick the grease in the fridge for a few hours if need be.

Can a coolant pressure test show no leaks?

The coolant pressure test is obviously showing a coolant leak. The system should not lose pressure if there were no leaks. Since the leak is not external, it may be getting burned. Maybe the intake gaskets leaking again?

What does it mean when your coolant level is low?

A low coolant level doesn’t necessarily mean a coolant leak. But if you’re refilling the coolant reservoir or radiator frequently, most likely the engine cooling system has a leak somewhere.

What are the symptoms of a bad coolant reservoir?

Coolant leaks. Another symptom of a potential problem with the coolant reservoir is coolant leaks. If the coolant reservoir cracks or breaks due to old age or overheating it will leak. Small leaks may produce steam and drips, while larger leaks will produce streams and puddles, as well as an obvious coolant odor.

What causes a car engine to overheat when there is no coolant?

Low Coolant By a large margin, the most common cause for engine overheating is simply a low coolant level. Your engine’s cooling system relies on coolant to circulate and remove heat from the engine. If you don’t have enough coolant in there to do the job, heat will build up and your engine will overheat.

Is it safe to run a car without coolant?

Yes, you can check to see if the coolant level is normal or if the radiator hoses sprung a leak, but unless you have all the necessary components in the trunk of your car, and are a DIY master/MacGyver, you’re probably not going to perform a roadside repair. Not everyone is cut out to be a mechanic, so play it safe, and leave it to the pros.

What causes an engine to overheat with hot coolant?

Overheating problems due to the head gasket may also be due to a break in the head gasket that is allowing combustion gasses to be pushed into the coolant. Depending on you engine configuration and the location of the water pump, the result could be trapped air in the water pump.

What happens if you find oil in your Radiator?

If you find oil in the radiator you have a major problem. There are two types of oil that could leak into your cooling system, transmission oil and engine oil. Transmission oil can enter your cooling system if the transmission oil cooler that is inside your radiator leaks.

How can you tell if a car cooling fan has gone bad?

To check an electric motor cooling fan, remove the key from the ignition switch and away from the car. Then reach in and spin the fan blade by hand, it should “freewheel” and spin easily. If it sounds rough or is difficult to turn it has gone bad and needs replacement.

What should I do if coolant is coming out of my radiator?

The radiator cap can deteriorate over time, letting antifreeze slip through when you are driving. A clogged radiator system could be a problem too as it blocks the flow of the liquid. Check the radiator when the coolant disappears without any trace. Replace the worn out radiator cap. Engine overheating and coolant are closely related to each other.

What does it mean if your car is losing coolant but no leak?

However, you may breathe easy if the mechanic does not find any trace of exhaust gases in the coolant. It means that the liquid has not reached the engine yet. The radiator cap can deteriorate over time, letting antifreeze slip through when you are driving. A clogged radiator system could be a problem too as it blocks the flow of the liquid.

What causes coolant to leak from the reservoir?
