It can be dropping from either the radiator or the hoses. The lack or shortage of coolant in the radiator can cause the coolant to change in color. The coolant of vehicles is mostly green, yellow, or pink.
This color can change to a thick brown-like color if there is contamination. This can obstruct the flow, and it can also clog the radiator. You might constantly perceive a sweet smell when you are around or inside your car. The odor of coolants is noted as a sweet smell.
Therefore, perceiving this type of smell can signify that there might be a leakage of coolant under your car. It would be best if you still investigate further to be sure of the cause. If there is a release of white smoke from the exhaust of your vehicle. What causes no coolant in the radiator but the reservoir tank is full? A damaged radiator cap can also break the hoses by building high pressure in them, creating another channel for the escape of coolant.
If the radiator hoses are always transporting hot fluid, then the hoses will wear out and will finally tear. Especially if your vehicle is used for daily long trips, the hoses on your car will wear out fast. The hoses might even explode, causing coolant to flow out from it easily. A bad radiator can be responsible for coolant not flowing from reservoir to radiator due to leakages. A damaged head gasket will turn the engine check light on.
The head gasket of your car is responsible for making a seal between the cylinder and the engine block. It also facilitates the smooth flow of oil and coolant. A head gasket blown can burn the fluid in the combustion chambers, which is very dangerous to your vehicle. You might not notice any leakage of coolant under your vehicle if the head gasket is faulty.
This component is located at the side or on top of the engine. The intake manifold gasket provides fuel and airstream to the burnt cylinders in order to provide power. A gasket is found inside the intake manifold where it merges with the engine. This gasket at the connection area with the engine can get damaged, leading to leakage of coolant in your vehicle. The radiator helps to cool the heated coolant as it passes through its metal tubes; this prevents overheating of the engine.
Damage to these components can cause severe leakage in the cooling system. I will highlight some ways to resolve the issue of no coolant in the radiator but the reservoir is full. These tips will aid you to protect your vehicle and also enable you to properly handle the situation where you are faced with any of the causes listed above:. In a case where your radiator cap is damaged, you will need to replace the damaged radiator cap with a good one. If you know how to perform this task, you can carry it out with the right toolbox , but you have to make sure that the engine is cool and the right radiator cap is purchased for your vehicle.
If you do not know how to do this, you should hire the services of a mechanic to assist you with resolving this. Going about this wrongly can increase the damage done to your vehicle. Radiator caps are not too expensive though it depends on the type you need. Suppose you have a case of worn-out or torn radiator hoses.
You have to park your car on a dry surface and let it cool down. If possible, let the vehicle rest for several hours. Then you can investigate if there is any leakage of coolant under your vehicle. Examine if there is any liquid on the surface of the hoses. You can tighten the hose clamp if you notice any leakage, and if it works, you do not really need to replace the entire radiator hoses.
In a situation where you find out that the radiator or water pump is bad in your vehicle, you need to get your vehicle to a mechanic shop immediately. The purpose of the radiator coolant overflow tank is to store excess coolant that is released from the radiator due to pressure build up from heat.
It works similar to an expansion tank on a water heater. As you may know, an engine that is working very hard will heat up very quickly. The oil alone is not enough to keep the components of the engine cooled off. The engine relies on coolant to ensure that it does not overheat during these high performing situations. While this heat is being generated, the coolant liquid will absorb all that heat so that the engine stays cool.
So what would happen if the coolant overflow reservoir tank became cracked, damaged, or overflowing? Below are common symptoms that may appear with a faulty coolant expansion tank.
As coolant gets hot due to it absorbing heat from the engine, the liquid expands and creates additional pressure in the radiator. As the pressure causes the coolant to get higher than the radiator pressure cap , the excess coolant needs to be captured somewhere in order to prevent leakage.
So, the radiator coolant overflow tank functions to serve this exact purpose. The excess fluid flows into the overflow tube and goes into the overflow tank. Once the driver parks the vehicle and turns off the engine, the heat dissipates which causes the coolant to not be as hot anymore. The coolant will then contract instead of expand; resulting in the volume of the coolant decreasing.
This is kind of like a vacuum effect where the pressure decrease allows the excess coolant in the overflow tank to flow back out of it, so it can return to the radiator.
If the radiator coolant overflow tank is damaged or cracked, then you can expect coolant fluid to leak out of it. Sometimes cracks will form on the overflow tank if it is too old and worn out. You should notice small puddles or drops of coolant on your garage floor or in your driveway. Note: Coolant is very harmful to dogs and cats. There have been many cases of dogs and cats getting very sick or even dying because they ingested engine coolant.
In addition to the coolant leak, there will be an apparent coolant smell coming from the front of your vehicle. Hi Mohammed, I am not sure if 0. Thank you so much I have replaced it with 1. Generally no. I am running an electric fan on the radiator and an electric fan on the ac condenser.
The radiator is a 4 row unit and cools well. If i put a recovery tank on the truck what cap pressure should I use? The radiator has a pressure release hose under the cap but there is no coolant overflow tank so when it gets hot the coolant just pukes onto the ground.
I am looking at different universal tanks online and see some with two valves one for in, one for out and other tanks with just one valve for both in and out. Which is best? How does the one-valve tanks work? Top off the radiator, then top off the overflow reservoir to the full line. Make sure you only do this when the engine is completely cool. It is very dangerous to remove the radiator cap while the system is hot and pressurized.
Add more coolant as needed during this process. I got the radiator replaced last year, but this is my first time at this shop. If your radiator leaks too much, your car will eventually overheat.
Some cars can leak a lot of coolant before any symptoms arise, but once you overheat an engine you are at risk of much bigger problems, such as warped heads and cracked blocks that will require expensive engine work or replacement.
With some temperature gauges, the needle only starts to move off center once your engine gets dangerously hot. If I did, does the bottle position or height relative to the radiator make any difference? And if I do install one, can I add a little more coolant to the radiator or do I still leave a couple of inches empty on top? Do I stick with the 15 cap that came with the radiator? I have a Toyota 4runner and I want to know if I should add coolant to my overflow tank or radiator?
Also after driving for a while, I noticed the coolant rises in the overflow tank and when left to cool off, the coolant level in the overflow tank drops most times below the full mark. What do you advice I do? Thanks in anticipation. The radiator should always be full, and the overflow reservoir should be between the low and full lines. This is a repeat, but please answer it as I have the same question.
I would check Nova owners forums to see if there is a common setup that works well for your vehicle, or if any owners have come up with an alternative approach.
