has anybody who owns a 91 ls400 re-charged youre a'c system if so. did you drain it? Did you convert it?

 

I have a 92 and my car has been converted to the R134. A/C recharges should be done by an experienced person as they can be dangerous for those who don't understand what they are doing. I have seen many people become critically injured due to trying to fill the wrong side of the A/C system, overfill, canister burst, etc. Discharging an A/C system out into the open air is technically illegal and needs to also be discharged properly. Please do not attempt to do this yourself if you are not a trained tech.

 

how much did you pay for the conversion also every thing under the hood is new so it has nothing to discharge i have the adaptor for the intake valve do you tink i should take it to a shop i heared it runs about 250

 

My friend is a mechanic and is certified to do A/C work. Had him do the conversion for me.

 

It is easy but you will need a vac pump, gauges and refrigerant along with common sense. Go here for good information
