HR6 or DA6? (Page 2/2) RWDPLZ AUG 12, 05:10 PM Yes, the switches are transferred over, they're held in with snap rings. If you break one, the replacements need a different connector, some versions of the new switches come with the new pigtails. http://www.fiero.nl/forum/Forum2/HTML/117640.html Check the instructions that come with the compressor for the oil type the manufacturer recommends. Ester VS PAG is still hotly debated with R-134A conversions. Fiero system capacity is 8oz. Drain and measure any in the compressor, and subtract from total capacity. The cycling switch needs to be adjusted (by a screw between the connector terminals) so that it comes on at 21psi with R-134A. You want to check this with a gauge set while you're filling the system, there are no set number of turns. Or you can buy a switch pre-set for R-134A.

A few questions: Do I put the oil directly into the compressor and put the plug back in before installing? Or fill the line where the orifice tube is? Will a vacuum remove any of the oil? I assume not since you have to fill before reassembly and you cant vacuum until after assembled. Everything I have seen states to use Ester Oil because it is compatible with mineral oil, which was originally used in the system. I read that adding PAG can create a glue like substance when mixed with mineral oil. Thanks for the advice! RWDPLZ AUG 12, 08:40 PM Put a couple ounces in the compressor, a couple in the condenser if you take it out to clean it, and the rest in the accumulator. Do this right before you vacuum down the system, as the oil and desiccant in the accumulator absorb moisture. The vacuum pump will not remove the oil. Replacing the accumulator and compressor removes most of the old mineral oil from the system, laying the condenser on the line connection side will drain most of the oil out of it, and flushing the lines off the car will remove the majority of the rest. Mct2green AUG 13, 01:50 PM How in the world do you get to the top front bolt on the compressor? I cant get a socket on it with enough room to ratchet from the bottom? Is there a easier way? Mct2green AUG 13, 04:34 PM I got the compressor out. the White mushroom switch cracked. advance auto has a Factory Air Compressor Mounted Low Cut-Out Pressure Switch #35756. Is this the correct replacement for the WHITE switch? It looks like the red switch is the high pressure. I want to make sure i got the right one. It has two wires, I understand to ground one and splice one to the existing harness. The high cutout switch is #35961. Is this correct? I dont want to correct? Last thing I want to do is install two of the same switches. My red switch came out with no issues, but the mushroom on the white switch cracked. RWDPLZ AUG 13, 05:11 PM No, 35756 is for the V5 compressor, you want the 35967 to replace the white mushroom switch. Yes red is the high pressure, replacement would be 35961. The top bolt, someone else may be able to speak to the V6, I've only done it on the 4 cylinder, laying on the ground next to the car with a ratcheting wrench. Mct2green AUG 13, 07:15 PM I think I will reuse my switch. Only a small part of the mushroom broke off. The wire still snaps in securely. I will just check it from time to time. The switches are easy enough to get to from under the car if I need to replace it later. Thanks!
