Discover the perfect fit for your 1992-1996 Rover Mini with our 15lb radiator cap, specifically designed for original side fitting radiators equipped with a sender unit at the bottom on SPI 1275cc models from 1991 onwards. This high-quality cap features a top rubber seal to ensure an airtight fit, creating a vacuum essential for models with an overflow bottle/expansion tank. The built-in small vent opens to draw fluid back from the overflow, maintaining optimal radiator performance.

Trust us to keep your classic ride running smoothly.
