What causes coolant to leak from the tank?
There are really only three common causes for coolant leaks, although each type of leak has several possibilities, varying in severity. You may notice that coolant has collected on the ground under your car or that your reservoir tank is not as high as it should be. This could be evidence of a slow leak in your system.
How can you tell if your car has a coolant leak?
A suddenly overheated engine is also another key tip-off that you may be facing a coolant leak. You may even be able to smell the coolant leaking. Oftentimes, the type of leak is easy to determine but sometimes it takes a little more effort to find it. It is a good idea to check the level of the coolant reservoir tank with every few gas fill-ups.
Why is coolant pooling under my car engine?
You may also find that you have a crack in the coolant reservoir. Since the coolant in the main system is what is keeping the car engine cooled, it will most likely not cause the car to overheat, but it is in this case that you will see coolant pooling under your car when it sits for long stretches of time.
Where does the coolant come from in a car?
Most likely you can easily spot where the leak is coming from by looking at it; a split or broken hose or a hole in the radiator are two good examples. Leaks in the water pump, heater core, or engine freeze plugs can also allow coolant to escape. These too are easy to diagnose by a visual inspection.
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 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.
Why is the coolant coming out of my radiator?
If you have a leaky or a weak radiator cap, you may experience loss of coolant from the overflow tube every time the coolant heats up. The radiator is a pressurized system so if there is a loss of pressure from the cap not fitting properly or if the cap is the incorrect cap for the radiator, the pressure will be lost and a leak could occur.
