AC specs check
Yeah I have no idea how that all got in there. Looks like compressor oil to me. Last year when my condenser line rubbed thru, this oil was dripping out. I have a feeling that the d-bag at the Napa auto care that charged my ac two years ago pumped way too much oil in. -

AC specs check
Think I found my problem. Pulled dryer off and it was filled with liquid. Swapped out my new dryer and pulled vacuum for 30 min. Left the truck to sit overnight and will check it tomorrow. Only thing I couldn't change was the orifice tube. Car quest only listed one for a 2007 dmax but the... -

AC specs check
ok then I need to do that. anything else I should replace while I'm in there? any is there any brand of Freon that is better than the others? edit- what I was thinking of- the orifice tube? you change that when you change the dryer right? -

AC specs check
I will check my pressures either tonight or tomorrow night. both times my ac lines blew (once in 2013 and in 2014) the system lost all Freon and was open to air for probably 3-4 days. -

AC specs check
ok bumping this back up. I haven't used my AC since I worked on it two weeks ago. Today its 83 and humid here, so I decided to try it out. I'm pretty disappointed with it to say the least. just doesn't seem my ac can cool my truck down enough. I have the digital climate control, I set at to... -

injector leak?
Did you change the washers when you had the injectors out? if not then I would pull it and change. I always put new washers and o rings on anytime I pull injectors. I think some guys reuses the copper washers, but they are only meant to be used once -

AC specs check
yes the fill spec is for pounds but in my case- where I initially overfilled and then pulled to much out, I have no way of knowing how many pounds I have in the system. unless I fully evacuate it and start over. So I use the pressure readings of the AC system to determine if you are over or... -

AC specs check
Ok I don't have the mechanical fan- got flexalites in. Got em wired to run when the ac comes on. I had the truck Rpms at 1500 with ac set on high and recycling when I took the temp readings. But at idle when I got out to check pressures. So at idle with my electric fans running I should... -

07 LBZ in my sig. I rubbed thru my AC line by my pass wheel well last year and lost all my freon. I replaced it and recharged- I accidentally overfilled so I just drained some back out. Now today I think I was under charged- driving thru town with AC on all of the sudden the air would... -

LBZ: I can get the ac system to work if I put water over the condenser
We are probably gonna need some more info about the symptoms too. like it wasn't working at all and then came on? or it was blowing hot and then you sprayed water and it started blowing cold? -

LBZ: I can get the ac system to work if I put water over the condenser

LBZ loud knock
yeah hes talking about the harmonic balancer. with the engine running you can look down to see if its wobbling back and forth. Or you can try putting a socket on it and see if you can move the balancer at all without moving the flywheel. the thing you said that would lead me against crank... -

LBZ loud knock
he said in his very first post he has a cylinder 3 misfire code and a balance rate of 12 on cylinder 3. I think we can make a pretty good guess its cylinder 3. I'd be pulling the valve cover
