How do I put freon in a 2002 Cadillac deville
Take it to the a auot shop. you can not add freon
You can add Freon to your 2005 Pontiac Grand Prix air conditioning system through the low pressure port. The low pressure port can be found on the air conditioner compressor.
on a 2001 grand prix the low pressure value to add freon is on the back of motor close to the firewall . if u look straight to the firewall there is a loop and black cap. there is where u connect the hose. and the high pressure line is underneath the airintake box that has black cap.
Buy a kit at Wal-Mart or auto parts comes with instructions
Look down between the air cleaner and washer fluid reservoir; the two A/C valves are just below the back corner of the battery. At least they are on my '92 Gran Prix.
Freon is no longer sold and available for use in vehicles, as it is extremely toxic and bad for the ozone layer. However, if you buy the currently available and used refrigerant for your car, you open the A/C valve and put it in there.
A 1966 Grand Prix did not come with a reservoir tank. You can add one though.
I belive the low port is located in behind of the front grill. I have a 99 GV. 2.5
on the low side only
You add the refrigerant through the low side service port.
I have a '92 model that has the ports just under and behind the air filter box. Look for the one with a BLUE plastic cap. leave the RED one alone.
