2005 Honda Accord hole in Condensor

Glennjd3 on Thu June 26, 2014 1:36 AM User is offlineView users profile

Year: 2005
Make: Honda
Model: Accord
Engine Size: 2.4L
Refrigerant Type: 134a
Country of Origin: United States

Drove to California and on the way home took a rock to my condenser. Put in leak detector and I have a ginormous hole in the condenser. Everything else checks out fine. My question is this. How much PAG 46 should I add to the new condenser? I know this is iffy but in general, how much is lost when the condenser is replaced? I have a new condenser and receiver dryer. I have a good grade AC pump and can pull a good vacuum. I'm planning to replace the o-rings. Is all 134a equal or are some brands better than others. What type of oil is best for lubrication of the o-rings. Finally, what are the specs for this system--I've found specs for the 2004 accord with the same engine but not for the 2005 (2004--19oz 134a; 5.5 OZ pag 46). Any advice would be gratefully received and followed. I am planning to add protection screens to the front air dam.

Thanks,
James

The best AC specs for your car are on a label in the engine compartment. This will list the capacity for R134a and the PAG oil. Most likely, Honda brand PAG oil will be specified which you can buy at the dealer.

The Napa doc says this for your car : "09-05 Excl. Hybrid - 19.00 Oz. R-134a; 5.50 Oz. PAG-46"
To find this doc, google for "2012_NAPA_Capacity_Guide.pdf"

You should replace the accumulator/drier too.

I will let the experts chime in on your other questions.

Thanks for the input. Is there any recommended amount of oil to add when replacing the condenser and accumulator? I really don't want to pull off the compressor. Ideas?

With a "ginormous" hole on the high side, it is hard to say how much oil was lost and needs to be replace along with that which needs to be added with the new condenser. Best to start from a known amount of zero (empty and flush) but I hope everyone can admit to not always doing this. Here is a guide, but it is only a guide and does not take into account the oil lost with a sudden release of refrigerant.

As far as brands of r134a, as long as it is pure 134a from a reliable source (a store not some guy selling it out of his van), I would not worry about the brand to much. Avoid any that comes with oil, sealers, oring conditioners, snake oil, and cooling enhancers. All the system needs is pure r134a and the right oil. However, adding a little dye while the system is open is never a bad idea and may help someone find the next leak if there ever is one.

I bought a can of 134a at w**-mart that had a stop leak, oil, and dye in it. It also had a hose and a gauge, so now I'm an AC pro!

Thanks for the advice. I just want to make sure I'm interpreting this correctly. If I put 35 ML into the condenser that should be in the zone for what was lost? Given that I'm replacing the condenser and the accumulator. Also, is Honda brand PAG 46 necessary or will the house brand do? I'm way off warranty. How long to you recommend drawing the vacuum? I usually run the pump for an hour, some recommend longer. What's actually necessary? Also what should the H/L pressure readings be on this car at 80 degrees ambient?

Thanks for all the advice,

James
