Engine Size: 5.7L
Refrigerant Type: R134a retrofit
Country of Origin: United States
I have a recently restored 1980 Chevy Camaro. It has the original A/C that looks in great shape; however it is not charged (mineral oil was previously drained from compressor). I want to convert it to R134a. ACKITS.COM was recommended and I have been doing some reading, so far the list of parts include the following. I want to try and do it right, hopefully the condensor, evaporator and compressor are in good working order.
1. Accumulator (which one ???); if universal need proper accumulator tube
3. O-ring Kit
4. O-ring lube
5. 8 oz Ester oil
6. 4 cans 12 oz R134a (42 OZ)....R12 was 52 OZ
8. Brass or steel conversion fittings for high side and low side (does new accumulator need fitting ? also does the pressure cycle switch need a fitting to fit on the new Accumulator ?)
Already have gauges, vacuum pump and can tap.
I plan on swapping out the accumulator and orifice, changing out all the o-rings, adding the 8 oz of ester oil and attemp to pull a vacuum to approx 28-29 "; remove vacuum pump and let it go over night to see if any leaks. If no leaks than charge with R134a and go from there.
Any tips or help choosing parts for my upcoming order would greatly be appreciated, especially the accumulator. Does the new accumulator already have a R134a connection for the lowside port ??? If so I only will need an adapter for the high side. Also is an adapter needed for the pressure cycling switch.

Sealing Washer Kit
Evap Mounted Orifice Tube
BVA Auto 100 POE x 2 You may need extra to flush old oil or shipping from compressor.
We do not sell refrigerant.
Conversion items: You need a label, low and high side adapters depend on the high side thread size. With out adapter the original vale core must be removed. One core to service port. HPCO is also required if the vehicle does not have one when converting t R134a.
Thanks Tim....I'm going to place an order ASAP !!!
Had (2) quick questions before I did:
1. What is the difference between the o-ring kit and sealer washer kit ? (also I assume the ester oil is sufficient for lube ?)
2. How can I determine which adapters I need ? For the low side it is on the accumulator. The high and low side threads are equivalent (schrader valves). Also I think I need an adapter for the other port on the accumulator which goes to the pressure cycle switch.
I may need a compressor but will test out the system first and place another order if needed....I'll go ahead and order spare oil.

Sealing washers fit the ports on the back of the newer style compressors where the hoses mate up. O=ring kit is for the connections on the rest of the system.
Forgot to add you should get some Nylog RT201b also.
Adapters are easy. Low side is always the same. High side can have a same or smaller service port than the low side on a r12 system. If it is the same size you need the 1/4 adapter. If the high side port is smaller than the low side port. You need the 3/16th adapter.
Thanks for the quick reply Tim !
