What causes coolant to leak from under the radiator cap?
When coolant leaks out of the radiator filler neck and dries, it often leaves white streaks behind. While you may not notice coolant leaking from under the radiator cap, look out for these white streaks.
What should I do if my coolant reservoir overflows?
In older automobiles, the radiator was made of copper and aluminum. In more modern automobiles, the radiator contains a lot of plastic. The plastic radiator are light weight, but tend to ware out faster. Replacing the radiator is recommended over applying a patch if the leak is found.
Is it normal for coolant to bubble up through filler neck?
It is often very normal for the coolant to “bubble up” through the filler neck as any trapped air in the internal cooling passages is forced out of the system.
How can you tell if your Radiator Cap is stuck?
Below are the top 5 signs. If the radiator cap is stuck, fluid cannot get released. This will cause pressure to build inside of the radiator, causing the hose to leak or break open. If you notice coolant fluid near the radiator or the radiator cap, then you clearly have leaky coolant.

Why is coolant leaking from my Nissan transmission?
Leaking coolant is mixing with transmission fluid through the cooler lines to create a toxic hell stew that irreversibly damages everything around it. Automatic transmissions in certain 2005-2010 Nissan SUVs and Trucks are under attack from their radiators.
Are there any recalls on the Nissan radiators?
The key to the petition was proving a safety defect existed, something Nissan has continually denied. NHTSA only forces automakers to issue recalls when there’s a safety risk involved. NHTSA found that the radiators are defective without a doubt. ” When examined under a microscope, cracks and fractures were observed at the lead points.
How big is the crack at the top of the radiator?
I have a small hairline crack at the top of my radiator (plastic). Its about an inch and a quarter long. When i turn the car on i see a very small puddle of water on the top plastic part of the radiator, that’s how I found this crack. Do you guys know if this can be fixed?
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 to do if your plastic radiator has a crack?
Mark the cracked area with a marker or tape. Then wait for the tank to cool down and take the cap off. Check if the crack is above or below the coolant level. If it is situated below, you have to drain some coolant until the crack shows up above the coolant level.
What are the symptoms of a bad radiator cap?
The radiator cap ensures that this pressure remains constant. There are several symptoms of a bad radiator cap like leaking coolant, the appearance of white streaks, and hose bursts caused by coolant pressure fluctuations. Excessive pressure causes cooling system component failure while less pressure could lead to the liquid coolant boiling off.
Why do you need a radiator cap on a car?
The radiator cap is the gatekeeper of the cooling system. The cooling system uses pressurized coolant (also known as antifreeze) to take accumulated heat away from the engine. Having a functional radiator cap is critical to this process, as it maintains the proper amount of pressure.
