Retrofitting the air conditioning system in a classic car, like this Factory Air 69 model, can be a rewarding project. Upgrading the car AC system often involves replacing several key car AC parts to ensure modern performance and reliability. This write-up details the experience of upgrading a classic car’s AC, including replacing the heater core and condenser, highlighting crucial steps and potential challenges encountered along the way.
Beginning the overhaul, installing a Sanden compressor is a common and effective upgrade for older systems. When working on the heater core, consider replacing the heater box foam seals simultaneously for optimal performance. It’s also an opportune time to inspect vacuum motors, a frequently overlooked car AC part, for any malfunctions. Addressing heater core issues and vacuum leaks at this stage can save significant effort later. Modifying the heater box might necessitate new firewall and heater box seals, essential car AC parts for preventing leaks and ensuring proper insulation.
Finding the correct AC bracket and tensioner pulley can sometimes be a hurdle, especially if original car AC parts are missing. Securing these components is vital for proper compressor mounting and belt alignment.
Moving to the expansion valve and hoses at the firewall, ensure you have the correct copper sleeve/clamp to secure the bulb against the return line. This car AC part is critical for proper refrigerant flow and system efficiency. Don’t forget firewall and heater box seals if modifications are made in this area.
Applying cork tape to car AC parts, particularly around connections, is essential for insulation and preventing condensation. Using manageable chunks of cork tape makes application easier and neater.
A common issue during installation can arise with the condenser. In this case, the nipple on the condenser hose end was too long, preventing a proper seal. This highlights the importance of checking the fit of all car AC parts. Modifying the hose end with a cutoff wheel and file resolved the issue, emphasizing that minor adjustments might be necessary for a successful retrofit.
Finally, selecting the correct V-belt, like a Duralast #17540 for a 351W engine, ensures proper drive for the compressor. Using the right car AC part belt is crucial for system operation. Upgrading your classic car’s AC system involves careful selection and installation of various car AC parts, but the result is a comfortable and enjoyable driving experience.
