Heater Box Replacement, Radiator Upgrade, Door Maintenance, and Turn Signal Switch Replacement On A 1966 Ford Mustang – San Diego, California

     I’ve been doing some needed repairs and replacements on this 1966 Ford Mustang. The owner has owned this car since 1975, and she decided it was time to bring her back up to specs. I replaced all the engine compartment electrical during the last visit. See Post. This time around I installed a restored heater box, upgraded the radiator, replaced the driver’s door window regulator, and replaced the turn signal switch.

     The heater box was original, and only the heater core had been replaced sometime in its life. The internal gaskets were deteriorated, and the motor was dragging due to debris that has been sucked up over the years. As a precaution, I check the radiator for clogs and rust. If the radiator has both, then the heater core will soon follow. The heater core is nothing more than a small radiator, but can get clogged much quicker. In this case, the radiator had large rust chunks stuck in the tubes. This was a great time to upgrade the radiator to a larger cooling capacity. The original was a factory two row with deteriorated fins. It was replaced with a high efficiency 3 row, and a upgraded fan shroud and steel five bladed fan for extra air flow. To protect the cooling system from further corrosion, I replaced the stock radiator cap with one that has a zinc anode. A zinc anode will corrode before anything else corrodes, and requires periodic replacement. The customer also went with a little bit of a concourse look with correct stamped radiator hoses.

     The doors needed some maintenance as well, so I adjusted and lubricated all the internal components. The driver’s side window regulator was frozen, so I replaced it with a concourse regulator for smoother operation. Whenever replacing a window regulator, you must check that the window goes up and down freely, or the regulator will have a short life. I also noticed that the driver’s door latch screw holes were cracked, so I installed reinforcement washers. The latch areas are only sheet metal, and is very common to cracking especially on the driver’s side.

     The last component  that was replace was the turn signal switch. I usually replace them because they no longer cancel, or the horn contacts are bad. This had neither problem. The cancellation lever was stripped, and someone tried tapping the threaded hole on the switch. The hole is thin walled, and had split. The only repair is to replace the switch.
