Air Compressor?

[1BADSS]

Can the Onboard air fill the tires on the truck?Just curious

[mjd932]

If it's at all like mine then yes.Look in the cargo compartment, there should be a hose long enough to reach all of your tires in there with a pressure gauge built in.

The two times I have used my air compressor for airing tires it cut off before completely filling the tire. I think there is a cutoff switch that kicks in when the compressor motor gets to a certain temp. The compressor will fill some recreational equipment such as beach balls, etc., but I don't count on it completely filling a tire. Can pump up a tire enough to get you going, but that is it. At least that is my experience.

I wanted to know cause I'm hopefully going to the track tommorrow, and when I lower my tire pressures I wanted to see if I could pump them back up before leaving.I'll just take a compressor with me.

Taking a back up compressor is a good idea. Why not try the SS compressor first and see if your results are the same as mine. If it can't fill the tires back to where you want them, then use the backup. Maybe I have a weak or bad compressor?

I noticed one of my coworker's tires were very low the other day and used it to fill it up. Worked like a champ!:thumbsup:

Did your compressor fill to 32 psi?

I had trouble airing up some beach toys with my Rainier. It seems to cut off the compressor when it heats up. It comes back after sitting for a few minutes.

Did your compressor fill to 32 psi?

Mine took all 4 tires to 38psi without cutting out.

Did your compressor fill to 32 psi?

I honestly can't remember. I think that I left it at 34.

The first time I adjusted all four tire pressures, no problem. Then last friday at the track it cut out a couple of times. Thermal overload I guess. I might look into a larger compressor.

how often does your compressor run?

[Gord]

I haven't used mine for long periods of time, so I can't answer the overheating question but I will say that the screw on connector is a pain in the ass... You get it to the pressure you want, then you lose 1 - 1.5 PSI while you unscrew the hose...

Way too often. I think there are some minor leaks in the plumbing.

If it's anything like a bicycle pump, which I assume it is, the air you're hearing leaking out is from the hose, not the tire. And when you screw it back on the 1.5psi you lose is to refill the hose again. You shouldn't really be losing anything.

Would a 2002 LTZ Trailblazer have this on-board air compressor? I've never heard of this but it sounds pretty cool. Where is it exactly?

[tbssny]

On the ss its in the right rear compartment a hose and on/off switch, hope this helps.:thumbsup:

The onboard air compressors main duty is to pump air into the rear air suspension that is load leveling. The load leveling suspension was an option on 2002 GMC Envoys, and maybe Olds Bravadas (not sure of this one). Then other high end GMT 360 370's got the option. Not sure if the GMT305's (GMC XUV) has this. The 2006 TB SS is the first TB to get this feature.

The compressor comes with an air hose to fill tires, recreational toys, air mattresses, etc.

mine seems to come on a few times a day without putting anything in it. even after sitting there for a few hours.

Mine does also. Especially after sitting for a while. Pretty normal.

[c72lt1]

Hook the hose up to the connection and blow it out before you use it for the first time. Mine blew out several ounce of water. You don't want to be putting any water in the tires.

Don't know if there is a little volume bottle in the system, anyone know?

The air isn't leaking out of the hose, it's coming out of both the hose and the tire while I unscrew the hose.

Does anyone know of a screw in atachment that would let me have a normal thumb release type connector?

[mcgyver7923]

The user guide talks about how the compressor will auto shut off when over heated. They make it sound like this is a normal thing..just wait a few minutes and go at it again. The way I see it is I leased my SS for 3 years and 36k miles so I'm going to use the crap out of everything on it and not be scared if it breaks. WARRANTY :D

My air hose / guage came with a smaller bag of parts, an air needle, a fitting to fill up a pool float, then an "air chuck" that doesn't have threads, you just push it onto the valve stem and release, no air loss at all.

Mine too.

I'll double check but I"m pretty sure I only got two attachments for filling up air matresses and stuff like that...

Thanks for the info though! Now I can ask the dealer to get me one if I don't have one already :D

I have all that too.

Yea i agree, I tried filling up my neighbors tire it was at 9lb. It took 10 minutes to get it to 40lbs What a POS:mad: Then tried another tire and it shut down for like 5 minutes then on for about 1 minute then off again. POS, only made for beach balls:p

[bostonsfavson]

I brought all four of my tires up from ~32psi to 35psi with no problem. The compressor will shut off before you can damage it. So you can definitely bring your tires up...you just might have to be a little patient ;-)
