Sorry for the delay in responding, internet service has been sporadic and I was locked out.Here is the info you need. Add 3.5 ounces of clean refrigerant oil to NEW accumulator.Add one ounce of clean refrigerant oil to condenser.Add 3 ounces of clean refrigerant oil to evaporator. If replacing compressor, drain and measure oil from old compressor. If less than one ounce is drained, add 2 ounces to NEW compressor. If more than one ounce is drained, add that amount to NEW compressor. 1994-1999 All Engines - Crew Cab ... R134a 36.00oz PAG 150 8.00oz Total system is 8 ounces. do compressor first and divide remaining oil in other areas.
