Removing ac condenser

Post by Dairy » 8 years ago

Does anyone know how to remove the ac condenser or at least help me out with draining it? Also how did the belt run for it. Did it have the same belt that is connected to the alternator?

A/C refrigerant is extremely harmful to the atmosphere. Best to have a shop that can recycle the refrigerant evacuate (drain?) the system so it doesn't escape into the atmosphere.

Belt was separate, its own belt, looped around the other (frontmost) crank pulley and its own adjustable idler/tensioner.

A-yup, 2 pulleys on the crankshaft dampner sounds about right.

Let me put my two cents in here . . .

Back in the day, say the 1950s, flash-frozen food (vegetables, fries) was frozen by running wire-mesh conveyors through a bath of Freon (a registered trademark of the Dupont corporation, I think it's the public name for diclorodifluoromethane, from the top-of-my-head. Let me Google that . . . yup, I remembered it right. It was a test question in my tech training in 1980; I had to be able to spell it correctly! ).

We're not talking about sealed units, these baths were open to the atmosphere, and tons of Freon were lost per day!

Compare that to the 20 ounces of R12 in a fully-charged automobile A/C system.

I would not be too worried about evacuating an R12 system to the atmosphere, myself. In a professional shop situation, that's different, where you might recover 10-100 pounds of the stuff per year, in addition to being able to filter and resell R12 (which is what we did, the last shop I worked at). The price of purchasing R12 is really high, so recycling it makes good economic sense.

But don't beat yourself up that you're destroying the planet if you open up your Maxima's A/C system and let the poisonous R12 out.

(I got the flash-frozen vegetables info from a food technologist that I worked with in 1989, who was there in the 50s. At the time, we were both working for a company that still builds custom food-processing equipment, huge stuff that fries 50,000 lbs of french fries per day, that sort of thing.)

IIRC, one sheave on the crankshaft damper drives the fan, water pump, alternator. The other is for the A/C compressor only. Do I have that right?
