NGK P559A-96222 Radiator Cap 96222 Standard Type

【NGK P559A-96222 Radiator Cap 96222 Standard Type】
■Product Description
NTK radiator caps maintain proper pressure inside the radiator through the action of the main pressure valve (pressure valve) and the negative pressure valve.
If the temperature rises and the pressure becomes too high, the main pressure valve inside the cap activates to adjust the pressure.
Conversely, if the temperature drops and the pressure decreases, the negative pressure valve activates to maintain proper pressure inside the radiator.

Specifications
Opening pressure: 88kPa (0.9kg/cm2)
NTK radiator caps prevent engine overheating by increasing the pressure inside the radiator and raising the boiling point of the coolant. For example, with an opening pressure of 88kPa, the boiling point of water increases by approximately 20°C to about 120°C.
【Features】
Main components are made of stable, rust-resistant materials.
Individual parts are optimally designed for excellent strength and durability.
Sealing rubber material uses enhanced heat and LLC resistance.
【Side effects of a faulty radiator cap】
Deterioration or deformation of the seal, damage to the seal, or dirt, rust, or deposits inside the radiator cap can impair the operation of the main pressure valve and negative pressure valve, leading to overheating.
【Replacement Procedure】
Removing the radiator cap when the coolant temperature is high, immediately after stopping the engine, can cause hot water or steam to erupt,
posing a risk of burns.
Always wait for the engine to cool sufficiently and the water temperature to drop before performing the work.
1. Prepare a towel or similar item.
2. Place the towel over the radiator cap and slowly loosen it.
Stop midway to release the pressure inside the radiator.
3. After releasing the pressure, slowly remove the radiator cap.
Be careful not to remove it abruptly, as hot water or steam may erupt.
4. Check the condition of the removed radiator cap.
5. Check the operating condition of the radiator cap with a radiator cap tester.
Even if the radiator cap appears to be in normal condition, the opening pressure may have decreased due to spring fatigue.
6. When installing a new radiator cap, tighten it securely until the tab meets the stopper position.
Type: Standard type

■Precautions
When inspecting or replacing, always stop the engine and work when the engine is cold. Failure to do so may cause fire or burns.
Do not use on vehicles other than those for which it is compatible. This may cause overheating.
Always check the vehicle's model year, vehicle model, and engine model using documents such as the vehicle inspection certificate.
Even if the vehicle's model year, vehicle model, and engine model are the same, the compatible radiator cap may differ, so please check the actual product (shape and pressure).
Coolant immediately after driving is under pressure, and removing the radiator cap can cause hot water or steam to erupt, posing a risk of burns. Please wait until the engine has cooled sufficiently and the water temperature has dropped before removing it.
After removing the old radiator cap, if any foreign objects are attached to the mounting surface, wipe them clean before installing the new radiator cap.
When installing the radiator cap, ensure it is securely attached until the cap's tab meets the stopper position on the radiator body's mounting opening.
