It depends on what kind of shape the VIR is in. They are rebuildable. Is this a restoration? Do you want to keep all of the OEM parts intact? If the vehicle sat with a failed compressor, but all of the lines remained connected - the VIR may be just fine. The heater core should be replaced since you ...

The V7 uses the block style suction / discharge setup common to GM products. I know there are aftermarket blocks out there, as well as OEM stuff. Here are a couple of GM part numbers for V7 suction / discharge hose sets, see if you can find one locally to look at: 10229469, 19213199, 15034761, 19169...

GM installed V7's in Orifice tube systems. Yes, you give up a little performance with increased OCR. You could add a TXV if you want - just remove the orifice tube & plumb it in. Adding a receiver to the liquid line in the process. I would start with the O/T setup you have & go from there. I...

Well, the biggest Sanden you will find is the SD7H15. It is a little bigger, but not a direct bolt up either: http://www.sanden.com.sg/opencms/opencms/sites/default/Sanden/_configuration/Catelogue/Product.jsp?pid=1005 You could use an ear mount V7 and get variable displacement in the deal as well as...

I guess you are using aftermarket brackets for the compressor? Afraid of OEM brackets?

An Sd5H11 to cool a barge like that? 108cc's / rev compressor & 30 ounces of refrigerant sounds right for a Corolla. The OEM A5 on that car was 210cc's / rev. Charge was 80 ounces of refrigerant. My first choice for a GM compressor would be the V7 - should be mounts for that, Corvette through 20...

Too clever by half.

A bypassing compressor could be diagnosed as any other system issue. A bypass valve would keep the refrigerant and oil inside the system where it should remain. With the laws regarding venting, and the flammability issues of things like yf1234 this should be obvious.

Post a picture of the plate if you can. If it is badly bent that may indicate a failure of the plate springs. Hard to say without seeing it. You can buy a whole new clutch, but a used plate will be just fine too. Yes you can drive it with the plate removed. The idler bearing is held on the case with...

Yep. The very nature of the HPRV leaves the spring & piston open to the elements. Low mounted compressors can have corrosion issues. Either the spring in the valve rusts away & it opens - or the whole mess corrodes & it fails to open at all. That valve should really be a bypass within th...

Here you go. First 3 minutes of that video should cover it.
