Expansion tank for Sierra Cosworth 3-door
Reproduced expansion tanks for the Sierra Cosworth 3-door.
Two internal reinforcements have been added to limit the excessive deformation observed on the original tanks, a phenomenon that could cause micro-cracks around the sensor area. These tanks have undergone laboratory validation tests:
Thermal stress: -40 to +115 °C
Pressure spike test: 5 bar
Durability test: 200,000 cycles at 2 bar (one cycle every 2 seconds)
