How to mount a AC Condenser
From Wheels of Time
An auto condenser should be mounting with in 1/8" to 1/4" in front of your radiator without touching the radiator. Mount the condenser with the large line at the top and the smaller line on the bottom. The refrigerant flows to the top and exits thru the bottom line with the refrigerant changing from liquid to gas in this process.
Always use the modern parallel flow condenser when using 134a refrigerant. These are as much as 40% more efficient with the smaller 134a molecules.
