You have to charge it on the low pressure side ONLY. That would be the bigger of the two air cond. lines. Usually there is a port that comes right out of the plastic box that is mounted to the firewall. Look for a port with a RED cap on it. Your Recharge kit hose will only fit on that line as the high pressure hose has a much bigger quick-connect port. It should take 3 cans to fill it . They are $15.00 each at autozone, don't forget a small can of oil first. If the third can won't empty try turning it upside down . Then it will go in as a gas not a liquid. Good Luck, Kenny.

My 2001 mercury grand marquis don't have a red cap on the low pressure line. The only valve that the hose fits is on the evaporator coil and the pressure is pushing out.
