Re: Help ac compressor not drawing in refrigerant upon charging

Your low side connector is not depressing the schrader valve. You are reading the cracking pressure of the valve on the low side.

Re: Drier for a Motorhome (Evans Tempco)

One of Ford's old dry break connectors. Info from the old board - been a while since I posted that http://www.autoacforum.com/messageview.cfm?catid=4&threadid=16459 Scroll down about 10 posts for pics & info. You could eliminate it. It is probably not assembled correctly at this point.

Re: Ac blew up on recharge.

Only one springlock? Then it may be a dealer kit.

Nothing wrong with that really, but it can make parts shopping fun.

If you used new parts everywhere, the leak is probably the gauge set - you said it blew a seal.

Did you install 134a service fittings, or are you still using the R12 ports?

Re: Ac blew up on recharge.

If it is an FS10, and all of the system fittings are Springlocks - the system is factory air.

Re: Ac blew up on recharge.

Sounds like a piccolo condenser. They have parallel paths, instead of a single pass. They are more efficient, but can hold less refrigerant too. I have a 1993 F150 with dealer A/C. Which engine is in your 150? and which compressor model is installed? Finding the leak is the first order of business. ...

Re: Ac blew up on recharge.

Was there oil already in the compressor? Is this truck a factory A/C unit, or a dealer install? Many 1992 & 1993 F150's actually had dealer installed A/C. What type of condenser do you have now? OEM was a tube & fin design, some aftermarket stuff is not. That first chart you posted is a real...

Re: Ac blew up on recharge.

Those pressures are way out of line for an ambient below 70f

You said you installed a new condenser. What brand & type is the replacement part?

Is the fan & shroud installed on this truck?

How much & what type of oil in the system?

Re: Is my compressor bad?

The condenser is likely full of debris. The evaporator is in the cabin, and is usually clean. The hose set is a maybe. The high pressure lines are subject to contamination, but if they have no mufflers they can be cleaned out - just make sure any solvent used is completely removed. Bare & dry on...

Re: Help Identify this compressor please

The compressor is available. There are 2 different units - one for cars with power steering,and one for manual steering. Call AMA on Monday at 602-233-0090 They can help you with the compressor, and very likely the manifold. Usually the manifold is swapped to the new unit when the compressor is repl...

Re: Is my compressor bad?

If it loads the engine to the point of stalling, it is trashed.

The debris from a compressor failure in that vehicle contaminates the condenser too - it is a piccolo type, and flushing is not cost effective.

A firewall forward replacement would be the best option.
