Follow these steps carefully
Find the under-hood A/C specification sticker on the 2019-2024 Nissan Altima and note R-134a or R-1234yf and the capacity. Confirm warm vents, compressor behavior, and that the cabin filter is not blocked.
With the 2019-2024 Nissan Altima switched off, identify the LOW-side larger-line service port. A DIY coupler must fit only the low side; do not force an adapter onto the high side.
Start the 2019-2024 Nissan Altima, select MAX A/C, recirculate, and high blower, then confirm compressor operation. Read low-side pressure against the kit chart for ambient temperature.
If the system is not near-empty and the kit instructions permit topping off the 2019-2024 Nissan Altima, add short bursts through the low side while watching the chart and vent temperature. Do not empty cans blindly.
Stop when the gauge and vent temperature reach the specified range, cap the port, and inspect for leaks. If cooling returns only briefly, stop recharging and arrange a leak test or professional repair.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
