Overflow tank looks good and performs as intended Rated by Kam on January 21, 2026
Summary: I purchased this overflow tank to secure to the side of a radiator/fan assembly on a Model A hot rod. It worked well, but It is worth noting that if you intend on adding this as part of a proper coolant recovery system (where hot coolant can be recovered back into the radiator once it has cooled), you really cant have the fluid level in this overflow very high while it is cold. I initially filled this reservoir with just a couple inches worth of coolant on a cold system, and volume difference while at operating temp/hot was enough to nearly overfill it.
Yes, I recommend this product.
