H&H Classic Parts - Overflow Tanks

The radiator overflow tank allows the water to heat up and cool down without blowing gaskets or caps when the pressure builds. It also allows the water to cool down before circulating back into the radiator, which keeps it full and working as it should. A properly functioning radiator keeps those Chevelle engines running smoothly without damage. The overflow tank must be a good fit for your car or there could be a loss of pressure or water, which can permanently damage your engine. If you have modified your engine or added a larger engine than the car had originally, you want to make sure you update all the other parts. When you add a new overflow tank, you only want to use parts that are reproduced specifically for the Chevelle. H&H Classic offers reproduction parts that are designed to fit your classic Chevy. Keeping your engine cool is easy when the parts you add work as they were designed to do, and no matter whether you need a 13-inch or 15-inch overflow tank, you will find it now.
