Description
Suit any original side fitting radiator with the sender unit fitted in the bottom on SPI 1275cc models from 1991 on.
This 15lb radiator cap has a top rubber seal on it to ensure an air tight fit creating a vacuum as these models were fitted with an overflow bottle/expansion tank. This cap has a small vent which will open and draw the fluid back from the overflow bottle into the Radiator from the overflow tank as it cools down.
