How to properly charge an Auto AC R134a?

The freon can should be upright so that refrigerant “vapor” is drawn into the low side. Remember that the Low side, also known as the suction side, normally operates as a “Low Pressure Vapor” state that is drawn directly into the compressor. You don’t want to “slug” the compressor by inverting the can…

Can a 134a Charger be used on an R12 Ford?

Replace or restore all rubber hoses with barrier hose. Install 134a charge port adapters. Charge with 134a between 70-80% of the original R12 charge amount. Replace any o-rings with 134a compatible. Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass.

What’s the charge rate on a Ford 134a?

Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass. Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.

How does the R134a high and low side A / C pressure chart work?

R134a Pressure Gauge Chart  This chart details how ambient temperature correlates with the system refrigerant charge pressure, and how it affects high and low side psi readings. It can be used for recharging refrigerant, or to diagnose an a/c system based on pressure readings from your gauges.
