Rear AC block off kit

Rear AC block off kit

If your vehicle has a leaking rear AC evaporator coil and it’s too expensive to fix, you can cut the lines to the rear ac block off kitrear AC evaporator and cap them with a rear AC block  off kit. The kits literally cap the line so you can continue to use your front AC to stay cool.

To install, evacuate the system and cut the AC lines near the rear evaporator. Then install the rear AC block off kit on the liquid and suction lines.

The brand I use is made by AirSept. You’ll need to measure the line diameters or consult a shop manual.
