Hi every ones, can somebody help my , I need to know what is the valve to fill the air conditioner of my dodge grand caravan 1998
Thankyou

 

You should fill through the low side valve or fitting which is the one close to the compressor. The high side is on the line near the RH frame rail. Normally, they are different sizes and the recharge kit will only fit on the low side fitting. There should be a plastic screw off cap over the fitting.

 

Thank you next2poo;l I appreaciate you help

 

The low pressure line also has a different color cap. You need to add freon on the connector located under the windshield wipers almost close to the firewall.

When adding freon, run the engine, turn the airco on and have the blower motor on max speed. Keep the can up side down and shake it while adding.

Hope that helps......
