Oil total and distribution for the system

uunfews on Tue September 09, 2008 5:45 PM User is offline

Year: 2001
Make: Honda
Model: Civic
Engine Size: 1.7
Refrigerant Type: 134a

I found out my car takes a total of 130ml of oil for the whole system and that the new compressor gets the same amount that was drained out of the old compressor but I can't find any specifications on how much oil should be replenished for the various part like drier, condensor, evap, and hoses if doing a replacement for each component. Can anyone shed some light on this matter?

Just dump the total system capacity into the compressor. If you can stick a wrench on the compressor's clutch plate nose nut and turn the compressor shaft 10 or 20 times, that would help prevent slugging the pistons/head when starting (if it's a reciprocating compressor).

I have a 94 civic, and the haynes manual that I have cover 92-99 yrs, has specific amounts for the part being replaced, example 94 civic, drier 1/3 ounces oil, evap 2 1/2 ounces not sure this pertains to the 2001, Haynes manuals are avail at your local auto part stores for about $15.00

as to bearings1 advice "Just dump the total system capacity into the compressor" I would not, you would obviously have too much oil in your system

Distribution numbers are typically used if you're just replacing one piece of equipment. If you add up the oil in each part it likely won't add up to the system's capacity.

I believe that is what unnfews is doing, replacing a componet, the reason why if you add all the total capacities from each componet it will not add up to total capacity, is the capacities for each componet is taking compensation for the oil that remains in the lines

The compressor used on this vehicle is a scroll design and adding this much lube into the compressor may result in serious compressor damage. Normal amount of lubricant to be added to the compressor itself should not exceed 2 oz.
The same issue with lubricant can apply to other compressors,esp the GM V series. These compressor require a specific lube charge method.
The 'old' adage of simply 'dumpin' it in' does not work well with some of the newer designed compressors.

Exactly, I am looking at changing the compressor and drier. I don't like to rely on third party information since their seems to be inaccurate most of the time. Take for instance this link I seen online regarding my car : http://napabeltshose.com/downloads/download_common.cfm?file=NapaCapacityGuide2-8-05.pdf&folder=news&view=napa_hc
My car on the owner manual as well as hood sticker stated 17.6-19.4oz of 134a not 23oz as per napa.

I am looking for info on from Honda OEM Shop Service and Repair Manual.

One source I looked at says 130ml for compressor and 10ml for drier but it is from an OEM 2002 Honda Civic Hatchback Service Manual.
