Where and how do I put refrigerant into an Oldsmobile tornada 90 ?|||Have a AC shop do it. If you don,t know where to put it in, you probably don't have any proper tools. The system would need to be pumped down and rescue the old refrigerant, system lubricated, checked for leaks, all before trying to recharge it. The gauges for this will cost as much as a normal service.|||i have a 1988 olds.delta 88 and i had mine recharged last summer and yours is probably the same as mine.on the passenger side,back by the firewall,theres a tank and a valve on it.get yourself a ac refill kit and screw the hose on the can and on the valve,now turn the little valve on the hose,and it will go into the tank.thats how a friend did mine.|||If you do not know the answer to this question, you absolutely must not do it. Anyway, if the vehicle has no sticker indicating that it has been retrofitted to the new R-134a, then your car takes R-12, which is now illegal for anyone to buy unless you are a professional automotive technician. Plus, there is probably a leak that has caused this problem, and if this is not corrected, it is most likely that this ozone depleting freon will dissipate into the atmosphere as quickly as you put it into the system.|||If we are talking about the AC, then you will find a fitting on the low pressure line. That will be the bigger of the two hoses for the AC. If you buy a recharging kit, it will have the right connectors and a pressure gauge along with the 134A refrigerant.|||for the older vehicles you have to get a kit to recharge it with the new stuff it will have the instructions with the kit i did that to my 93 gmc i think the kit is called retrofit?, anyway if you get the hole kit it should come with the adapters that just screw on to the old fittings, a hose, and the refrigerant and lube for the compressor. i got mine from napa but most common auto parts stores should have it.|||i own a repair shop,and it always goes in by the tank side on it or the nearest one to the back,you can retro fit this to use 134 -a ,and it will cool it just as good,and its lot cheaper also and easier than using r-12,,but that's where it goes in at,good luck i hope this helps.
