This Chevy deluxe heater core is a bolt-in replacement of your leaky, decayed original. Even when repaired and tested, original heater cores often spring new leaks due to age and weakness in the core and seams at the tanks. A really good way to ruin your new dash pad and carpet! We always recommend replacing this part even before the first signs of trouble. The part features an all new core soldered to new top and bottom tanks and brackets. It is ready to install inside your stock 1957 classic heater box on the firewall. When replacing this core, you should also replace the control valve P/N 35-50. Solve or prevent leaks and improve the operation of your heater with a Chevy deluxe heater core!
