Product Questions & Answers

Q:I want to install this on my 1966 Pontiac GTO to stop coolant flow to the heater core. Is the valve plastic or metal? Are BOTH nipples 5/8"? Show Less
anthony c.
A:BEST ANSWERHi Anthony, thank you for reaching out. This item is metal. We don't have the exact measurement of the ports since this item is a direct fit for the Ford/Lincoln/Lincoln trucks. This item is incompatible with the 1966 Pontiac GTO. Should you need further assistance, feel free to call our Sales team at 1-866-529-0412. Show less
