Re: AC has a loud short bang at startup then cools normally

Too much oil (or a really tight compressor) could cause a high torque issue at startup - which would cause the belt tension to go sky high & bang the tensioner stop.

If the clutch itself is actually making a banging noise, it is not right. So yes, swap it out before it does something worse.

Re: AC restoration questions, '93 Mazda RX7

Yeah, you will need to host the photo someplace else to post it on here. I have seen some ludicrous FMIC installations over the years here - with posters wondering why the A/C no longer works. With any sort of changes to the heat exchanger stack, it is always good to make sure the fan is pulling air...

Re: AC restoration questions, '93 Mazda RX7

If you are putting in a huge intercooler, you will need to be sure that the condenser airflow is not compromised. Using a larger condenser is a good plan, because of the increased air temperature at the face. Plenty of choices out there. CTS Cadillac condenser has been a good swap for me a few times...

Re: New to me '03 Ford E150 has zero freon.

I don't think I would charge an empty, unknown system. I would be inclined to pull the compressor & see if it has any oil in it. I know it is an E series, and a pain to work on. Perhaps pull the accumulator & check it for oil? Some of those vans had scroll compressors, others had the FS10 pi...

Re: 1961 cadillac conversion

Just another kid with a sanden catalog , Tim. Interesting that one vendor caused the Original Poster so much trouble though. Supplied an inadequate compressor for a car that big, AND a "custom" defective evaporator. And the only way the OP got the the bottom of it was coming here - for free.

Gus:

You asked about Sin City. I have never heard a bad thing about them, and I think Chris keeps about half of the E30's in Las Vegas on the road.

If you replaced the tensioner 6 years ago, it might be time. Sometimes aftermarket replacements just don't last as long as OEM.

Re: Compressor Short Cycles with Correct Charge

Try another gauge set. Your control system appears to cycle off at all sorts of different low side pressures. Either the switches / sensors are bad or your gauges do not repeat. Before you go after the control system, try a second set of gauges to make sure you are not chasing your tail. You have re...

What is the high side reading while it cycles?

BMW used a hydraulic tensioner for the belt in that car.

Open the hood, and locate the tensioner. Have someone start the car, then turn on the A/C while you watch the tensioner.

Re: Seeking help with my Lexus/Toyota A/c

Absolutely. If you are finding bits of foam coming through the vents, something is failing.

Mitchell DIY subscription is $20 for a one month access. You get the whole factory service manual.

Well worth the price, you can save days of work on jobs like removing the a/c evaporator box.
