Product Questions & Answers (1)

Question by: Billy H on May 15, 2025, 7:54 PM
got a straight 4-1/2 inch coolant run to replace, is this hose actually 4.50 ID and 36 inches long?
Answer by: Customer Support on May 17, 2025, 12:46 PM
It is a straight 36 inch length with a 4.50 inch inside diameter and a 4.89 inch outside diameter, so it matches a 4-1/2 inch ID coolant hose size.
