Leaking Heater Core

SONY DSC

Q.

My 1963 Chevy Nova is almost restored. New carpet was just installed. I replaced the heater core once and it leaked on the old carpet after 4 years of use. Is there any place that will repair old cores? Can’t have a supposedly new core leaking on new carpet.

A.

There was a time when virtually every town had a shop dedicated to radiator repairs, and yes they would often do heater core repairs as well.

Over time the cost of replacement radiators has come down, so much so that in many cases it is much cheaper to buy new than to repair.

In doing a few quick internet searches for your car, it revealed heater cores were available in both aluminum and brass/copper, and could be had for as little as $30 and as much as $150.

There are times when no one makes a replacement heater core, in those events I would seek out a radiator repair shop that still makes radiator repairs, and they will have the skills and equipment to make the repair.

I recently had a radiator repaired, and while it took a few phone calls to find the right people to work on it, the reward was having a first rate job personally backed up by the shop owner with a promise and a handshake.

Because your car is so popular I would strongly recommend purchasing a complete new heater core. As repairs to your existing one will likely exceed the purchase price of a new one.

Wrench Safe,
