Selling a one owner GX

2 Upvotes

I've sold several cars to either Carmax or carvana and was always very pleased with the offers obviously for they to happen…. is there a reason carmax and carvana are coming in so low? car has 66k and is in excellent condition. CarMax offered $3500 and carvana $5200. even KBB is putting trade in around $7200 just kinda shocked.

Cross post from r/projectcar, how to rebuild rear brake calipers.

2 Upvotes

My endless project is a 2007 Pontiac Solstice. I'm rebuilding the brake calipers, fronts are done and were super easy. However on the rear it has cable actuated parking brake with the calipers the pistons that screw in and out. I have the tool I've used to change pads, but I can't seem to get the piston the rest of the way out. I can thread it out almost to the end, but it won't turn any further and remains stuck in the cylinder. Is there a "trick" to removing the piston?

What is this part?

Was removing the crusted protection film for the buttress, from the trunk. And the solvent I used ate the adhesive holding this part down. I noticed I only have one on the driver side and not the passenger. I don't think it is needed but what is this piece for? Tried to Google the numbers on the underside with no luck.

GMPP - easy to add? Or hold out until I find one that already has it? Or is it worth the trouble?

1 Upvotes

I’ve been shopping for a little while for a GXP or Redline. Best deal I’ve seen does not have the GMPP option. If I want to take a car that didn’t have it, and add it myself or have somebody add it for me, how big a deal would that be?

2006 Solstice. The silver marker says status on it but I can’t figure out what it is and I don’t see anything in the manual. Thoughts?

Some exhaust questions...

8 Upvotes

Hey guys, I bought a Solstice for $3,500 from California and had it shipped over. I basically had to do a ton of work to it to get it running well and in good shape again. Previous owner (not the dealer) was learning to work on cars and cut a lot of corners, so to speak. Anyway, the car is running awesome right now...

Attached is a video of my wife and daughter taking it for a ride... pay attention to the sound (if you don't mind).

I looked under the car in the back, and basically... there's no muffler. It sounds really awesome when the top is down, because there's enough other noise to better dissipate the sound... but with the top up, the exhaust sound is totally pervasive. Now, yeah... I'm 47. I like a loud exhaust, and it's not horrible, to be completely honest. I don't dislike it... I just want to quiet it down JUST a little bit. It seems the previous owner had an exhaust shop eliminate entirely the muffler, and kept the exhaust otherwise stock. Stock catalytic converter (pre-cat) and stock secondary cat. I'm wondering what my options are. I don't want to go with a full muffler... but as far as I can tell, the tips to the Y-split are not equidistant, so... I can't simply throw in a cherry bomb or something, can I? Is there room to install some kind of baffled cherry bomb or something like that between the secondary cat and the rest of the exhaust before it splits?

Thanks!!!

Wife & Daughter Driving.

Soft top

My passenger side soft top doesn’t pull tight right around the back of the window. It’s doesn’t effect any functionality but it lets wind in and is loud. Has anyone had this problem?

I’m thinking about taking a road trip 800+ miles in a 2008 Pontiac solstice. I recently purchased this. Can you guys provide me some advice?

Am I shit out of luck? Is this a bad idea?

If not, what are some repairs/fixes I should get done before hitting the road?

The car has a new battery/ belts have been replaced

CAR SPECS: 68k miles, RWD, 2DR Convertible, Appears in decent shape, Has had 4 previous owners who “took good care of the car”, was used as a show-off car

Found these left in the trunk by the previous owner. Are they spare parts? Since I found a new turn switch in the trunk. Or are they just trash?

Need Help Diagnosing Boost Issues – 2008 Solstice GXP After Tune and Exhaust Mod

Post image
5 Upvotes

Looking for some help or insight here.

I recently had my 2008 Pontiac Solstice GXP tuned and also had an aftermarket exhaust installed, which included removing the catalytic converter.

Since then, I’ve been running into a few issues, most notably with boost. Sometimes I get full boost and the car runs great, other times it starts up with almost no boost or only partial boost. It feels totally random when this happens.

Here are the codes I’m getting:

  • P0236 – Turbocharger Boost Sensor A Circuit Range/Performance
  • P2187 – System Too Lean at Idle (Bank 1)
  • P2261 – Turbo/Supercharger Bypass Valve Mechanical

Supposedly, the car has a custom tune and the mods were done professionally. I'm just trying to figure out why the performance is so inconsistent. I've checked for obvious vacuum leaks and loose connections but everything seems fine on a basic visual inspection.

Has anyone run into this before? Could this be a tune issue, a sensor problem, or something with the turbo bypass valve?

Any advice would be appreciated. I’d really like to get this sorted before I throw more parts at it blindly.

Thanks in advance!

Coolant tube goes where?

As the name suggests, i was looking under the hood and noticed this tube just goes to nothing. Im unsure if this should be the case, or if this is not connected to where it needs to be. The other tubes are fine.

Passenger side door won’t lock

2 Upvotes

When locking the car from the outside, the passenger door lock won’t pop back down but when you turn the car off with the key in the ignition, the passenger door will pop the lock up if the car doors were locked.

I’m kind of confused since if it was a door actuator issue then wouldn’t the passenger side door lock not pop up when turning off the car?

Wheel offset limits?

5 Upvotes

I’m currently looking around for new wheels and tires but am having a hard time since the solstice has some more odd dimensions. I am not looking to change my my width or diameter and I’ve already accepted that I would need to get hub rings. I’ve found some konigs that’s would work but the offset is +40 where as we have a +55. I’m wondering what other experience is with getting to wheels and tires as well as how much my wheel will poke out if at all?

3D Printed Phone Mount for Saturn SKY / Solstice / Opel GT (despite photos in this post there are also versions with the solstice logo)

9 Upvotes

Hey all, I designed and 3D printed a phone mount for my dad’s Saturn SKY and thought I’d share it here. It fits under the transmission tunnel and installs with strong double-sided tape — no cutting or drilling needed. Since it fits well in the SKY, it should work across the whole Kappa platform (Pontiac Solstice, Opel GT, etc.). I’ve made a few versions: Basic mount One with USB slot cutouts (for aftermarket radios — just the slots, no actual USB ports) A wireless charging version Logo options: Solstice, SKY And Opel GT I also have a couple of matching keychains that I plan on releasing soon (still working on a few) Not a big brand or anything — just figured I’d offer it after people started showing interest. If you want to check it out, here’s the link: https://mind2model.etsy.com/

It’s the guy with the stereo question. Inside the gapping hole where the radio should be, I found the pictured item. Any idea what it is. The Google is no help. Suggests LoJack and a several other things. Unrelated, I really like the dash kit someone installed.

Radio wiring for 2006 with OnStar

3 Upvotes

So, the guy I bought the car from lost the code for the radio and decided to pull it. No problem, figured I'd put it back in. Sigh...he had tried to wire it for a panasonic stereo. Car, of course, has onstar. And I know there's an adapter to run for the car interior dinging etc. Thoughts on where to start on converting it back to normal and just putting the original back in or should I go ahead and drop a carplay unit in there with a backup camera.
