It sounds as though you might have added air to the system. To get rid of air pockets, the FX needs a bleeder valve for the coolant. Open the bleeder valve, turn up the heat, start the car, and “massage” the radiator hoses. If air is trapped in the system, air bubbles ought to emerge from the valve.
Additionally, anytime I change my coolant, I empty the engine by unplugging the block’s plug. I doubt the FX has this.
You used a 50/50 mixture of coolant and distilled water, correct? HTH.

Are radiators bled in cold or hot weather?
Step 2: Turn off the heating. Turn off the heating completely and wait for the radiators to somewhat cool down because the system needs warm water to be in it for bleeding radiators.
Is it better to bleed radiators when the heat is on or off?
Should I bleed the hot or cold radiators? Before attempting to bleed your radiators, always make sure your boiler is off and your central heating system is cold. Your radiators hold hot water when they are turned on, so bleeding them now puts you at risk of burning yourself.
Will the cooling system self-bleed?
Depending on the model and approach you use, it typically takes 15 to 30 minutes. However, heating the engine and draining the coolant both take about 15-20 minutes.
Between the overflow tank and thermostat, your cooling system can leak a little. However, you must fill the coolant and drive the vehicle with the radiator cover off in order to fully bleed.
The water needs to be turned on and adjusted to run slowly. To remove the radiator from the cooling system, turn off your car.
What results in excessive radiator pressure?
Leaky hoses are the most frequent cause of radiator leaks, but the radiator itself can also leak, which can be a bigger issue. There is a lot of pressure created by the coolant flowing continuously from your radiator to your hot, running engine and back again. Your radiator hoses will eventually perish due to that pressure buildup.
The hoses will eventually deteriorate or become loose, allowing coolant to leak out of the system and eventually causing overheating. Your radiator is leaking if you notice green fluid under your car or nearby and you smell something pleasant. Even if your radiator’s hoses are in good condition, excessive corrosion can still result in a leak in the radiator’s body.
As part of routine maintenance, replace your radiator hoses on a regular basis.
What location is the coolant bleeder screw?
Typically, the bleeding screw is situated near the top of the engine. The connection between the top radiator hose and the engine is most frequently made directly on the thermostat housing. Your cooling system has a bleed screw if you observe an orphaned, single screw; some systems, though, come with more than one bleed screw. If necessary, consult the owner’s manual or repair manual for your vehicle.
Make sure the engine and radiator are both cool before you start this procedure. Wait an hour or more if they are heated.
- Remove the radiator cap when ready.
- If necessary, add distilled water and antifreeze in a 1:1 ratio to the coolant to raise the level as needed. The mixture should be poured into the radiator until it reaches the bottom of the radiator neck.
- Additionally, fill the reservoir with coolant. Increase the coolant amount till it says “Cold.”
- Radiator cap should be changed.
- Place a pan on the ground to capture the coolant that will leak out of the bleed screw after you find it.
- Activate the bleed screw. Attach the end of a 4 foot clear hose to the bleed screw after turning it twice counterclockwise. The hose must tightly fit over the screw. Put the hose’s other end in the catch pan underneath the car.
- When the engine has reached working temperature, you will feel the upper radiator hose become hot. To bring the engine to operating temperature, start it and let it idle for around 20 minutes.
- Retighten the screw when you notice a stream of coolant flowing through the clear tube without any air bubbles.
- Remove the clear hose and the catch pan from beneath the car after turning off the engine and letting it cool.
- If extra new coolant is required, fill the reservoir, radiator, and radiator neck all the way up.
- Check to check if the temperature remains within the typical ranges while you test-drive your car. The third step below, “How to bleed a radiator using two jack stands,” is where you should go if not.
- Check the coolant reservoir periodically over the following few days to make sure the proper level is maintained.
How can you tell whether your radiator is filled with air?
To check and bleed your radiators, simply follow these easy steps:
activate your heating
As you turn on the heat, give your home’s radiators some time to warm up.
Determine which radiators need to be bled.
Make sure that the temperature is consistent throughout the whole surface of each radiator by carefully inspecting each one. There may be trapped air inside certain radiators, and you will need to bleed them if you notice any radiators that are cold at the top or hear any gurgling sounds.
We advise putting on a pair of light gloves to check each radiator because they could be very hot.
Turn off the heat and let the radiators cool before continuing.
We advise turning off your heating system before bleeding any radiators so they aren’t too hot to handle.
Under the radiator bleed valve, place a cloth.
Find the radiator bleed valve, and make sure that an old towel or a piece of fabric is positioned beneath it to catch any water that may be released.
The bleed valve is present on every radiator. They usually appear as a round hole with a square within and are situated at the top corner of a radiator.
Release the air by opening the valve.
When you bleed the radiator, if no water or air comes out, the valve may be blocked with paint. Remove the screw from the bleed valve’s center after closing the inlet and outflow valves at each end of the radiator. Slowly turn the bleed valve counterclockwise using the radiator key. As the air is released, you should hear a hissing sound.
In case you accidentally open the valve too much, we advise keeping a bucket nearby to catch any water that may splash.
Shut the valve.
Turn the key in the clockwise direction to close the valve when the hissing has stopped and water has begun to leak.
Verify the boiler’s pressure.
For each radiator in your home that requires bleeding, repeat this procedure. Check the pressure in the water pressure gauge on your boiler once you’ve completed doing this.
Repressurize the system if the boiler pressure is too low (below 1 bar). You can turn on your heating and check to see whether your radiators are now heating up as they should be if the pressure is normal (between 1 and 2 bars).
Why is my reservoir empty but my radiator full?
The radiator hoses that allow fluid to flow from the coolant reservoir to the radiator may be leaking or clogged if the overflowing coolant reservoir does not return the hot coolant that needs to cool down. It can be due to a cracked radiator cap. If your radiator cap is broken, the coolant in the radiator will be able to escape, which will prevent it from returning to the reservoir.
Nissan uses a unique coolant, right?
Nissan Green Coolant has a shorter time frame than blue coolant in terms of duration. Every four years or every 60,000 miles, it must be replaced.
A specific variety of Nissan Green Coolant is the 999-MP-AF000P. Knowing that this cooling agent is concentrated will help you understand that it must be diluted with water before being poured into your car.
Why does the cooling system in cars get airlocked?
Your automobile may have overheated for a variety of reasons, but inefficient cooling is frequently the root of the problem. Your engine’s cooling system is essential to its efficient running. Your cooling system uses the circulation of coolant or antifreeze to dissipate heat from your engine. The cooling system in your car is incredibly intricate and relies on the engine as well as the radiator, heater core, thermostat, water pump, and hoses to perform its essential function.
Your cooling system’s leaks are frequently to blame for an overheating engine. Leaks allow air into the system in addition to obstructing coolant circulation. Large bubbles that cannot be forced through the system form as a result of “airlock,” which happens when there is air in the cooling system. Airlock can significantly reduce coolant flow, causing heat that should be dispersed to remain inside the engine. Similar results occur when your cooling system becomes blocked, with the engine overheating as a result of poor circulation. Foreign items and mineral build up are two major reasons for blockages.
Overheating may occur if a water pump fails. The water pump is crucial to the operation of every cooling system because it keeps the coolant flowing. Engine overheating may occur as a result of a broken or worn water pump, which can happen over time. Overheating is frequently the fault of the coolant. The dip in temperature, particularly during the winter, can cause coolants to vary in consistency. In colder climates, your coolant may turn gel-like, restricting circulation and possibly causing blockages. Car overheating can also be brought on by something as straightforward as low coolant levels.
Why is my coolant bubbling even though it’s not hot?
When the engine is not overheated, coolant bubbling in the reservoir is typical. Most often, a minor repair is all that your car needs in this situation. It can be due to contaminated/low coolant levels, air in the radiator cap, or both. To identify the underlying problem, you might require a proper diagnosis.
Replace the radiator cap if necessary. The coolant can also be topped off or completely flushed before replacement. After that, drive the vehicle. If the bubbling ceases, a damaged radiator or low/contaminated coolant is to blame. Take the car to a mechanic if the bubble persists.
Can you combine Nissan coolant in green and blue?
Nissan Green and Blue coolants can be used together, but be sure to first dilute Green in distilled water and then use. The mixture’s lifespan will be equal to that of green coolant, which is 4 years or 96,000 kilometers/60,000 miles, if you combine the coolants.
How can I tell if my cooling system has air that is stuck inside?
One of the many indications that there are air pockets in the coolant system is a broken car heater. There won’t be any heat coming from the vents when you turn on the car heater. The air could not be forced out because of the air bubbles. Hot fluid cannot enter the heater core because of the trapped air.
How can air be taken out of a heater core?
This technique can be compared to how we put a child to sleep after hearing it burp. Take your car for a mountain drive if you reside in San Francisco or a nearby mountainous area. On a slope, park it in an inclination. If you don’t have access to this equipment, jack up your automobile so that the front end is higher than the trunk. As you do the following:
- Prepare your coolant container by getting it.
- Slowly remove the radiator cap and drain some coolant to prevent bubbles.
- The heater valve automatically permits the coolant to flow through the heater core once it reaches operational temperature. The air bubble is forced outward by this motion.
- In this situation, let the automobile sit for 15 to 30 minutes.
- Keep an eye on the radiator’s coolant level. Occasionally, you will be able to observe the coolant bubbling and burping. Once you notice that the bubbling action has stopped, begin adding the coolant gradually.
- You ought to witness a constant flow of coolant without any bubbles or burps after around 20 minutes.
