How much freon is needed in a 1992 sunbird?

Answer 1

First are you sure it uses R12 or has it been switched to R134A.

If it still uses R12 where are you going to get it ...it's about

Thirtydollars/lb.

if you are licensed to buy it....ie you are certified or get certified on line

at http://www.macsw.org/certification.php and then buy it ....or go to

Mexico and buy it for

six dollars/can of 12 oz.

Or if you want switch to R134A or if it is already R134A then crank up the

engine ...close the windows connect the R134A or the R12 (CFC-12) put

a digital thermometer in the ac vent in the center of the car turn on the

ac and watch the temperature form outside the car. If it's about

60 F or higher start adding gas slowly and watch the temp...

when it gets as low as it will go some cars 50 some cars 55 some

40 aome 45 stop adding gas....your done....have fun! and stay cool
