What is a safety release radiator cap? MotoRad safety lever radiator caps utilize a lever that locks the cap to the filler neck requiring the lever be lifted before removal. When the lever is lifted, the valve pressurizing in the cooling system is opened and pressure is vented through the overflow tube making it safe to remove the radiator cap.
What does the safety lever on a radiator cap do?
We have reached the end of our list, and this radiator cap comes with the safety lever. Since this radiator cap is from MotoRad, you can rely on the quality of the cap. The safety level helps in the removal of any residue pressure before you open the cap. It ensures that the water doesn’t splatter around, and you are not injured because of it.
What is the guarantee on radiator caps?
The guarantee assures that the radiator caps are reliable, and the brand is ready to take ownership of faulty caps. Pay attention to the price of the radiator caps and steer clear from any outlier in the market.
What is a high pressure radiator cap?
Note – In the new cars, most manufacturers started introducing high-pressure radiator caps to eliminate pressure build inside the radiator. These caps have a special valve to get rid of excessive pressure and preserving the coolant from contaminating at the same time.
How does a radiator cap work?
This radiator cap has a safety lever that allows you to release the pressure when you are changing the cap. The cap is easy to change, and it fits perfectly on most of the vehicles. The quality of the cap is excellent. Nothing that we could notice. We have already shared the list of best radiator caps with you.
What is a safety radiator cap?
Coolant Caps MotoRad radiator pressure caps are designed and manufactured to offer precise pressure control for the automotive cooling system. Most standard radiator caps are also offered in a version with a safety lever feature and each part is factory tested prior to shipping to customers.
What are the different types of radiator caps?
there are four different types of cap:With lower seal only, with free-hanging vent valve (Partial-pressure, open system)With lower and upper seals, with free-hanging vent valve (Partial-pressure, coolant recovery system)With lower seal only, with spring-loaded vent valve (Full-pressure, open system)More items...•
Can you take off the radiator cap while the engine is running?
After the pressure releases, push down on the cap and turn it until it comes off. Removing the radiator cap while the engine is hot can cause the coolant to spray out, seriously scalding you. Always let the engine and radiator cool down before removing the radiator cap.
Does the radiator cap release pressure?
The cap is actually a pressure release valve, and on cars it is usually set to 15 psi. The boiling point of water increases when the water is placed under pressure. When the fluid in the cooling system heats up, it expands, causing the pressure to build up.
How do I know which radiator cap to use?
Each cap is different depending on the model of your car. The owner's manual often has the correct pressure rating listed that is necessary for your car. If the pressure rating is not listed in the owner's manual, it will be under the hood on top of your old radiator cap.
Is there a difference in radiator caps?
Radiator caps can come in all shapes and sizes unique to your car's radiator. Different vehicles have different systems and therefore work with individual pressures. Ensuring it all works smoothly comes down to this one little piece of the puzzle.

Around inside your dash. When you're operating your vehicle.
What happens if you open coolant while hot?
Never touch a hot radiator! Absolutely never try and remove the cap of one. When your radiator overheats pressure builds up and the resulting rush of steam and hot coolant when opened can cause third degree burns and permanent scaring.
What happens if radiator cap pressure is too high?
Unchecked high pressure could cause damage to the radiator, heater core, hoses or water pump seal. The pressure cap also prevents radiator hoses and tanks from collapsing. As the engine cools it causes a vacuum in the cooling system. This vacuum draws the coolant back in the system instead of air.
What causes pressure build up in radiator?
Leaks. The most common cause of radiator leaks is leaky hoses, but you can have leaks in the radiator itself, too, which can be a bigger problem. The coolant continually running from your radiator to your hot, running engine and back again creates a lot of pressure.
What happens if you leave the radiator cap off?
Overheating can cause damage to an engine, and a seriously overheated engine can be irreparable. When the garage left the cap off the overflow reservoir , the cooling system was unable to maintain pressure which means that the coolant boiled and would have spilled out into your engine bay.
How long does a radiator cap last?
On average, a radiator cap could last about 10-years. This lifespan could increase or decrease based on the frequency of use. If the frequency radiator use is high, the lifespan could decrease, on the other hand, if it is not high, then lifespan could increase above 10-years.
How tall is a radiator cap?
The top section of the radiator cap’s diameter is 2.6 inches, and the height of the radiator cap is 1.06 inches. The spring system helps in retaining the pressure.
Why is my radiator rusting?
Rusting is mainly because the coolant can be corrosive. If you are changing the old radiator cap because of the corrosion, you might want to look at this option. This radiator cap is highly resistant to oxidation. It has a long service life, and it can resist high levels of pressure as well as temperature.
How much pressure does a radiator cap hold?
The radiator cap can hold the pressure between 14 pounds to 18 pounds. If you have a faulty radiator cap, then do not buy the ones at the dealership. This radiator cap is available at a fraction of cost when you compare the price of the radiator cap available at the dealerships. Pros.
Why does a radiator lid need to be sealed?
The lid has multiple seals, and these seals help the radiator in ensuring that the pressure can buildup for the circulation of the coolant. A faulty cap can lead to overheating of the cap as it will reduce the pressure, and hence it will reduce the boiling point of the water.
Why is coolant reservoir important?
The coolant reservoir helps in keeping your car temperature lower. When there is an issue with the radiator cap and it is stuck, it will build pressure inside the radiator. The worst part is, it will cause leakage in the hose. You can find dripping coolant under the car.
What is the pressure rating of a radiator cap?
It is a standard radiator cap that fits most of the vehicles. It has a pressure rating of 16 pounds, and it performs pretty well in all types of conditions. This radiator cap works as expected, and you will not face any issues with the cap.
What is the role of radiator in a car?
The car’s radiator acts as a heat exchanger, transferring excess heat from the engine’s coolant fluid into the air. The radiator is composed of tubes that carry the coolant fluid, a protective cap that’s actually a pressure valve and a tank on each side to catch the coolant fluid overflow.
Why does coolant pressure increase when it enters the radiator?
When it enters the radiator, the pressure increases even more because it’s in an enclosed space. The radiator cap acts as a release valve set to open at the maximum pressure point.
How does coolant fluid work?
This way, the coolant fluid is mixed together, cooling all the fluid evenly, and not just cooling the fluid that touches the sides of the tubes. By creating turbulence inside the tubes, the fluid can be used more effectively. When coolant fluid overheats, it expands, causing the fluid to become highly pressurized.
How does transmission fluid cool?
Cars with automatic transmissions cool transmission fluid in the same way with a separate heat-exchange circuit built into the radiator. This two-step process of cooling the transmission fluid is equivalent to a radiator within a radiator. As the heated transmission fluid enters the transmission cooler, the oil’s heat is exchanged with ...
