I guess metal, but not little dirt, right? If you are not changing the accumulator drier, you don't need to drill a hole to drain the oil. There is an aftermarket blend door kit, does anyone have experience with changing it thru the evap hole? But if flushing, out the system then a total of 7 oz needs to go in system, some in accum. If a charging station is not available, system charging may be accomplished using a separate vacuum pump, charging cylinder, and manifold gauge set; refer to Manifold Gauge Set Connection in this section. Set the blower motor speed to maximum and allow the remaining refrigerant to be drawn into the system. I changed sister n laws focus last week, compressor and also changed out accum. Catastrophic is somewhat difficult to define.
I removed the condenser when I did this. Please make it easy on me--there must be a max of oil to put in system-- So how much can i load into system? Observe the low-pressure gauge for 5 minutes to make sure that the system vacuum is held. Quest: when i did ford focus sister n law last week--i put oil in ports of compressor, and turned sideways to manuver into manifold lines, back of compressor oil would leak out from ports, so got someone to hold upright while doing it. If vacuum is not held for 5 minutes, leak-test the system, service the leaks, and evacuate the system again. It would be great not to change accum. The label is missing from the engine compartment, so I need to know what the proper capacity is for the R134.
Just want to know for sure before my friend fills it up. Now for some questions: Going to change evap and accum. I know drawing a vac will not affect the oil, just moisture. I pulled the motor and there are no stripped gears. So, I would add a couple of ounces to the compressor. Our Mercury parts and accessories are expedited directly from authorized Mercury dealers strategically located all across the U. Most of the oil was lost when the evap exploded, nice puddle under the truck.
If certain components of the system are removed for replacement, some of the refrigerant oil will go with the component. Bobby This is from 2000 Shop manual 7. Dilemma: Haynes says drain oil from new compressor, yet instructions on new compressor says don't drain remove the 1. How would i do it by myself if no one is around to help--which probably and most likely is the case? I hate moving things, fear that other things move with it or brake. Close the charging cylinder valve and allow the system to pull any remaining refrigerant from the hose. Ford Parts Giant is your prime online source with the biggest and best selection of genuine Mercury parts and accessories at giant discounted prices. Now for the charge question.
Continue to operate the vacuum pump for a minimum of 45 minutes. If not flushing, but changing the orifice tube, add 2 ozs to the receiver inlet as above. A local pro also told me today if he did the repair he would dump up to the whole 7oz of oil in there after what happened and all that time with a hole. So if not doing flush then add 2 oz to compressor, it probably has 1. He said its a big system and an extra bit of oil reserve has place to go. Just making a little sound now when turning on compressor. To ensure reliability, purchase Oil - Compressor - Air Conditioning.
Do i put it all in compressor, but it may overflow out of ports. To maintain the original total oil charge, it is necessary to compensate for the oil lost by adding oil to the system with the replacement part. I'm thinking it would be easier. I'm wondering what the best way to recharge. But says max out at 6 oz next--haynes says drain oil from accumulator after drilling holes in bottom and add same amount to new one plus 2 oz--don't exceed 7 oz;s next-haynes says if replacing condenser then replace 1 oz--i am not replacing condenser, but if i flush it, then it would be same as needing oil. If it is not due to catastrophic failure, you wouldn't need to flush the system. I would rather not flush with solvents since oil otherwise is clean.
So what do i do????? Lets says 3 oz although haynes says i can add up to 7 oz if that much is drained from it to accumlator and 1 oz for condenser because i would flush system if needed maybe, then that would have a potential of a whopping 14 oz's---Sounds like way to0 much pressure in system Could haynes have assumed i am not replacing compressor and accumulator,otherwise there formula for adding oil would over load system. I bought the pag 46, thinking of pouring 3 oz in the accum and 3oz in the evap. . I just did a motor swap on my 2K excursion with a 7. Ford Parts Giant has you covered no matter what type of Mercury vehicle you drive. When the suction pressure drops to approximately 207 kPa 30 psi , close the charging hose valve.
I thought I read somewhere that Ford increased the capacity on the excursions for some reason? If you are changing it, follow the Ford procedure. Orifice tube full of junk. Guess one would have to look at orifice tube first. The total charge is 7oz oil. This part fits specific Mercury , models. The compressor requires tons of dexterity to move around and in front of radiator already. But what a contradiction or something left out.
But haynes says if replacing compressor then replace accumulator, so they can't assume that. He said the pag deteriorates with moisture, and he always overfills those compressors by an ounce or three! Continue to add refrigerant into the system until the specified weight of R-134a has been added. Also, can a professional machine remove all oil if the charge is all gone? I plan on adding the oil, then drawing a vac, then charging with 3 cans of pure R134a truck takes 33 oz I believe. It seems to work fine, exept for one click when at max or min temp. Now a question: Why are you changing the compressor? While the evap is out, I'm thinking of fixing the blend door as a preventitve measure. . .
