Engine Cooling coolant protection and re-distribution in system
The expansion tank absorbs excess coolant and minimizes excess pressure in the engine cooling system.
An expansion tank helps maintain a minimal pressure increase during heated water expansion, helps reduce coolant hammer, and helps protect the engine cooling system from stress. Furthermore, the expansion tank ensures that there is no spilage by re-distributioning excess coolant into the system.
To help avoid and prevent premature failures, your expansion tank should be checked annually.
La solución de Nissens
The expansion tank range includes 26 items, covering +105 OE numbers and +360 truck models.
OE Matching Quality
All Nissens’ expansion tanks are designed, manufactured and tested to match OE quality.
The expansion tank development process includes a number of tests, such as vibration, pressure-impulse, thermal expansion, and burst, eliminating the risk of leakage or insufficient cooling performance.
First Fit - all that is needed in the product box.
Fits the engine layout and the relevant connections smoothly. Fully compatible with the vehicle systems.
Beneficios del producto
High Performance Welding
All expansion tanks are welded with advanced machinery to ensure the strongest possible connection of the top and bottom part.
Each individual tank is leak tested before shipment.
Highest quality fittings that ensures a secure and consistent fit that will last.
OE Matching Plastic
Nissens’ always use PA66GF33 or PP Plastic, matching OE quality. This ensures advanced heat and stress resistance.
All materials are tensil tested and no recycled materials are used.
All sensors are individually function tested and pre-mounted on the expansion tank for quick installationAll sensors are individually function tested and pre-mounted on the expansion tank for quick installation
A blocked expansion tank can cause leaking or bursting in the engine cooling system as the connections, fixtures and components get stressed and damaged due to excess pressure.
If the expansion tank is leaking, the engine could overheat as the level of coolant in the system could decrease.
Note the level of coolant in the expansion tank when the engine’s cold. Once the engine reaches operating temperature, the level must rise. If it doesn’t, the system is not operating properly.
