Was looking into the grill area yesterday and noticed some oil on the ac/transmission coil...seems to be a leak on the ac side. Theres a Youtube video replacing one on a 2006 GC, doesn't seem too involved as long as you have access to ac equiptment. Theres an aftermarket coil for on Ebay for $90. Oem are 3,4 times the cost.

AC, just like any other system, the way to tell how bad the leak is, is to check the quantity still in the system. Also, your leak might NOT be the condenser itself, it could be the O-Ring at the connection for the tube. Also, if you had a crack or pin-hole in the metal condenser itself, most likely the AC would be totally empty and non-functional in minutes, best case scenario within in days. As well, this liquid on the condenser is actually AC oil leaking out of the system, its possible its something spilt from the shelf above it when you were changing oil or something splashed on it while you were driving.


So, I think you're jumping to conclusions that you need to replace your AC Condenser. Check out the AC system, see if it is working correctly, troubleshoot it properly, and see if it points to a leak. If the leak is at connection to the lines, fix the seals and lines first.


Yes, the OEM AC parts are extremely expensive, and there is a lot of cheap sub-standard AC parts out there. NO you don't have to buy the extremely expensive OEM dealer parts, to have a reliable AC system, but most of the cheapest parts, especially moving parts like compressors are sub-standard and the AC system won't last using those parts. i.e. find a happy medium of quality, don't have to buy the most expensive, but avoid the absolute cheapest that you can tell is NOT any quality.

The leaks on the opposite end of the line connection...and it really hasn't been warm enough to run the ac. I agree with using oem parts for compressors and like moving parts as well as electrical and electronic replacement parts. The replacement im considering is made by Denso.
The oil is dark, unlike the pinkish transmission fluid which runs through the top quarter of the coil.

The refrigerant itself will evaporate right away, its invisible, the PAG oil in the system is yellowish to clear oil. It could quickly collect dirt and darken though.


Well AC still runs when its cold out, you could turn it on and test it. If the Compressor won't even engage with the AC on full blast, that's a good sign that it has leaked out so much refrigerant the low pressure switch won't even let the system turn on to prevent damage.


If it runs, other than just a swag at how well it cools, you'll need a set of AC gauges put on the hi/low side to see the pressure relationship with the ambient temps to tell if its properly serviced or NOT.
