• Failure to follow these rules may result in your threads being locked, deleted, or moved. Depending on the severity of your actions, or frequency of your actions, your user account could be suspended or banned. These rules are to help protect both buyer and seller.


    1. CONSOLIDATE all of your for sale items into ONE thread only. This means there will be NO making multiple sales threads for different items regardless if the parts are related or not.

    2. PRICE IS REQUIRED. We do not permit ads without an asking price for each item. "Best Offer" is not an allowable substitute for posting a price. You may ask for $1 but a price must be listed regardless. If a price is not listed with in the first 24 hours of making your sale thread IT WILL BE LOCKED or DELETED. Once a price is listed a bidding war is not permitted. If the seller gets an offer that meets his asking price, the seller should honor the asking price and sell for that amount.

    3. EBAY LINKS AND OTHER LINKS. We allow links to ebay ads, but you MUST have a buy-it-now price posted, or an asking price to stop the auction in your ad here (Not just in the link). If it is from another site or from here, do not use a link but post the full text instead with pictures if you have them listed. If a BIN price is not posted, then your thread will be DELETED.

    4. CITY / STATE are required info for each ad. Information must be posted in the first post of thread, NO EXCEPTIONS. Buyers and sellers reserve the rights to privately ask for full contact information on any purchase or sale. 24 hour notice will be given, if you do not comply your post will be DELETED.

    5. NO TWO PARTY SALES. This means no more "I'm selling for a friend" posts and will be deleted immediately with no notice. Seller assumes all responsibility of anything they post for sale.

    6. NO FEELER THREADS. You are either selling it or you aren’t selling it.

    7. POST COUNT AND/OR TIME LIMIT. We are requesting that you spend some time with us before you start a For Sale thread. A pre-determined minimum number of posts will be required or 1 year since creating the account + an intro thread (just so we know you aren’t the Prince of Africa). Any for sale thread posted out of the For Sale section to circumvent the rules will result in being deleted. Those who do meet the criteria and post outside the section will have their thread moved, constant violation of this will result in an infraction.

    8. NO BUMPING OR TT’ing YOUR THREAD MORE THAN ONCE IN 48 HOURS. Don’t worry your thread will still be a bold read until a user reads it and if people are really interested they will let you know. Post warning will be issued if in violation and on the 3rd warning, the thread will just be locked.

    9. NO THREAD DUMPING OR I DON’T LIKE YOUR PRICE. Don’t post in a person’s thread just to tell them they are too high, either move along and say nothing or throw an offer to them. The person can sell it at whatever price they think someone is willing to pay. Offenders will be issued a warning, if it is a constant issue then an infraction will be issued.

    10. KEEP YOUR THREAD UP TO DATE. This is really for your benefit, so you don’t get 10 PMs asking if you still have it when you already sold it.

    11. NO WEAPONS. As Admins we have determined that no weapons will be allowed to be sold, this includes knives, guns and anything else deemed a weapon (even if its a wall hanger only). We ask that if you want to sell these items you seek out the appropriate websites elsewhere to do so.

    12. Pictures are REQUIRED. Pictures of all items for sale. This is to help BOTH seller and buyer. As a seller it is MUCH easier to sell something if you have pictures of it. As a buyer you feel better seeing exactly what you are buying. Pictures should contain the item/s for sale and a sign of some kind that has your username on it. 24 hour notice will be given, if you do not comply your post will be DELETED.

    FRAUD & RISK. Buy and Sell at your own risk. Grand Prix Forums and its staff are not responsible if someone rips you off or doesn't send parts out in a timely manner. This classifieds section is a free service for the community, and it is YOUR responsibility to handle all transactions in a low-risk method. DO NOT contact us if there is a dispute between you and someone else, we are NOT INVOLVED. You can help minimize fraud risk by doing these suggestions:

    Pay using PAYPAL, using a credit card. This way, if a part does not arrive, you can do a charge back through your credit card company. If you gift it, then you have no recourse to get your money back when things fall through. Pay the 3% and have the buyer protection. Using someone else's paypal and gifting to pay for goods is violating Paypal's Terms of Service.



    Always ask for full name, residential address, phone numbers of both buyers and sellers. An honest seller should have no problem disclosing this info to you privately.


    Shipping things C.O.D. is risky. Try to use UPS or Fedex, so that you can track shipments. Have someone sign for it if it is expensive.


    Ask for references from other members, hopefully from other members who have been registered for longer than one year and are active here.


    Use your gut feeling. If something seems too good to be true, or a seller/buyer seems a little shady, don't take the risk.

    TIPS:
    -Post pictures: with mobile phones these days and auto uploads, it’s not even really hard anymore. Have it automatically drop in Photobucket, grab the Img tag link and paste it in.

    -Give good contact information if you aren’t going to be on here a lot.

    -If you are going to disappear for an extended time (vacation, time in jail, what have you), then give us a quick note that you aren’t going to be around. People will trust you a little more.

    -Look around and gauge your price with other items. Just cause you bought it for $1000, doesn’t mean it’s now worth $1,200 or even the original $1,000. You are free to ask what ever you want, but an item that is priced right will sell quicker.
  • The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

WTB LS4 water pump and TPS

2006 Grand Prix GXP
Really need a new water pump (mine is leaking around the pulley) and a tips or throttle body. My idle speed is about 20mph and my rpms are at 1100 when it used to sit at 5-600 at idle and I was told I need to replace my throttle position sensor... Which I also found out that I need the whole throttle body? If I'm wrong please let me know.
 


You are correct you will need a new TB. Someone on here recently bought a new TB for same problem. The water pump is really simple to do and if I where you id replace the thermostat as well while ur at it. Aren't u parting out a GXP. There's ya a used TB

not to jack but i noticed it looks like mine is leaking as well, marines, you say its pretty easy to do? Figure remove battery, battery cover, fuse box?
 
Yea remove battery and leave the fuse box outta the way. Take belt off. Then remove the cover. Here around 8 I'm going back to my room there's a good video I have plus I'll inclued the GM manual instructions as well with it

Edit: I helped a friend who has an impala and it took longest putting the serpentine belt back on lol

thats for just the water pump? if mine shows sign of moisture on the other side of housing is that gonna be the seal for the whole unit itself?
 


yea...the water pump i purchased came with a new seal and the pump and seal thing was only like 50 bucks from rock auto. the hardest part was getting the dang belt on and off...that was a bit*h without the proper tool but i was able to get it off with a socket and long extension bar and 4 hands

I am parting it out but I think that when the battery caught on fire that it shorted out all the wires on the engine harness because some of them are melted even where the heat didn't get to them.. Would heat or a short hurt the throttle body? Also, how about the water pump? won't the seals be all jacked up since it's on the same side as the fire :(

You are a life saver! Now to do the TB...
 
The seals very well could be but if u were taking the pump off of any ls4 I would replace it anyways. Their only a couple bucks. And a short could damage it but I would try the one from the one ur parting out just to see if it works or not

Very true, it's not like it would take very long to swap, everything is right on top. If i had to buy a new one though, i was told that they are 250 bucks minimum and that they are extremely hard to get ahold of
 
When I did it on my buddies impala as the pump I got off rock auto costs lime 40 or 50. But total I charged him 100 for the work and that was still way cheaper than letting the shop do it for him

Oriely's auto quoted me at 147 bucks for a new pump with gaskets.. should i just order one online? Are they trust worthy replacements parts though? I really don't want to ever have to do this again. If you could send me a link to the one you purchased that would be great. That'll save me a ton of money since I can put it in myself

Yup. Its what I used all you'll need from there is basic wrenches and a tool to remove the serp belt. I do not recommend doing it the way the guy in the video did.

Got everything fixed the other day. You weren't kidding about the hardest part being the stupid belt. I would have almost rather pulled the trans than do that again lol.
ended up buying a brand new pump since the one in the damaged car was all burnt up. I did however manage to get the TPS off the burnt car without a problem and it works great!! No more 1200 RPM idle speeds. She's sitting at a nice and quiet 500-600 after it's warm. Thanks for the help on the water pump! You saved me a ton of money.
