Issues with Stillen lightweight crank pulley

nomodsjk

I am wondering if anyone has had issues with after market lightweight crank pulleys damaging serpentine belts, barrings or altinators? If anyone has read my thread about my csf radiator install nightmare this thread is related. Today, after a long ordeal with the dealership botching the installl, my ac compressor went out. This was the first time since picking up the car on Tuesday that I've tried to turn on the AC and immediately the compressor seized. I was told this was a coincidence and had nothing to do with their work. They told me it was related to a faulty after market part and pprobably had something to do with my crank pulley. The compressor went haywire as soon as I turned on the AC. I refuse to believe it's a coincidence. They told me they will not work on my car anymore and to take it elsewhere but they will reimburse me after the fact. It's been almost 3 weeks and cost me 1014$ for the install. I'm really mad and I feel rightfully so. Can someone please tell me if my Stillen supercharger kit could cause this? Please

If you run the A/C low of R134a due to a leak this could have caused your issue. The low pressure switch should have kicked in and saved the compressor. If you didn't see alot of oily residue from the R134a leak then yes, it was just your time for the compressor to fail. Hope you had a new dryer installed when you had the radiator/condensor changed. The dryer is the filter for the A/C system. Anytime you break open the system you are supposed to replace it. Not really much the dealer could do to mess up the compressor. The only thing I can think of is if the system got low on oil.

Ok cool that was helpful. Just seemed like one hell of a coincidence

How would one check this oil level? And I don't remember them saying anything about a dryer. Also I'm getting the new compressor installed on Monday so any advice between now and then would be greatly appreciated just don't want to have this happen again

I would have been checked by the A/C tech. When he vaccumed down the system, he should have collected the oil that was evacuated by the A/C machine. He would then open a valve on the machine and dump it to a container that would measure the oz.'s of oil recovered. He would need to add that much back into the system while it was under a vaccum and no leaks were discovered. (it needs to hold a vaccum for 30min and not change a around 28-30 inchs of mercury. (can't remember the values, it has been 15 years ago since I was a tech).

Make sure you have a new Reciever/Dryer installed. It is attached to the condensor (round cylinder where you probably had your leak). I would also have new oil added. I would have added 2 oz. for the new condensor, but with a new compressor, it has new oil in it since it will be under a vaccum. I would talk with them and add 2-4 oz of new oil.

Thank you sir. I really appreciate your time and input! I love being a forum member.

If you were closer, we would take it to a friends shop to use the R134 A/C machine and do the work at my house. LOL

Make sure you get the source of the leak narrowed down to ensure it dosen't happen again.

Forgot to add, if the compressor shelled out, have them clean out all of the lines. They would run A/C safe solvent through it, and then blow the lines and condensor out with compressed air. You don't want any metal muching up this compressor.

I will relay the info. Thanks again.

Honestly after speaking with you on the subject I'm really happy with Nissan for agreeing to reimburse me for this. Originally I was really upset with them but now not so much

If you can't tell, I have had some bad luck with this myself. It started the, screw it, I will do it myself mode. This acutally turned into a full time job for me while I went back to school. I was a dealer technician for several years.

I once took my car in to a Z only modified shop for an issue. I had an intercooler installed at the same time. I then had the car retuned. While the tuning was going on the tranny blew. It suxed. I paid for the parts, they rebuilt it for me. Needless to say, several months later I was passing another car in 5th gear. I started to hear a knocking sound. I downshifted to 4th and it went away. Come to find out, I tore 3 teeth of the 5th gear counter gear. LOL At that time a search for a T-5 manual 280zx turbo tranny insued. I still have the car today running 11 psi of boost (1975 Datsun 280zt). Needs paint and a bunch of new parts installed that I have hoarded up. Working on that.

It's always freaking something with these Damn cars but I still love my car on an unhealthy level!
