If you are doing any A/C work, it is well worth it to upgrade to this more efficient, modern, parallel-flow condenser. The original condenser was designed for R-12 refrigerant; however, due to environmental concerns, R-12 has been phased out in favor of R-134a, which (unfortunately) is not quite as efficient. Using this condenser will make up for some of this loss of efficiency and restore your A/C to like-new performance (assuming everything else is in tip-top shape, of course).
To be clear, you still get the advantage of increased efficiency, regardless of the refrigerant you choose. Most shops in the USA will only install R-134a, but if you are using R-12 or R-12a, upgrading your condenser will result in increased performance over the stock, serpentine flow condenser.
Compatible with all common refrigerant types: R-12, R134a, R12a (RedTek, EnviroSafe).
Comes with instructions, adapter hose, and mounting hardware for a seamless install.
Fits all 1983-91 Vanagons equipped with factory A/C.
