Engine Size: 4.5 L
Refrigerant Type: R134A conversio
Country of Origin: United States
I'm planning on helping my son to replace the compressor his Q45 - it is a Calsonic. The vehicle was retrofitted to R134A before my son bought the car, now compressor is noisy.
I plan on draining and flushing evap, condensor, replacing exp valve, drier and compressor, vacuuming system, and charging. I have a dessication system (silica gel column through which shop air passes) on my shop air, I will be using it to blow oil and mineral spirits through system hoses and components, I plan on removing and flushing evap core, with exp valve removed.
1) Are the ACKits rebuilt calsonic compressors worthwhile, and/or what type oil and quantity should be used in this system?
2) This car has externally compensated exp valve, with capillary tubing and temperature sensor bulb. Does this type of exp valve function properly with either R12 or R134A?
3) Is an inline filter worthwhile on this car, and if so, since it is metric, which size is correct?
I feel we use the best manufactures in the business. With any item it can fail at times. Anyone telling you they have had zero failures is being dishonest.
Compressor Type Calsonic V-5
Oil Capacity 8.0 ozs.
Refrigerant (R-12) Capacity 38-41 ozs.
System Operating Pressures
High Side 142-173 psi (10.0-12.2kg/cm2 )
Low Side 27-33 psi (1.9-2.3kg/cm2 )
Many seem to think that mineral spirits is a great flush for A/C system......check this out....this is the result of a mineral spirits based flush being used. This came from a major supplier in the southwest that used a mineral spirits based flush chemical. The trouble with mineral spirits is getting the stuff out of the system.
Chech with site sponsor for a more acceptable flush......HECAT is good....that "cool' stuff......think twice...hard to remove from system.
The strongest reason for the people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government.
