Is there anyway for the service department to find out if you used a smaller pulley if you were to remove it and swap the stock one back on before taking it up to the dealership? Maybe some kind of log or whatnot in the computer that would say how much boost you were running?

 

Nah I wouldn't worry about it, the only way for it to log it is to know how fast the S/C is actually spinning, and there's no such sensor. So you're safe! Plus where I got mine, the service department said that it doesn't matter what I do to it as long as its not a direct relation to any future problems. For instance, a pulley isn't going to make your starter go out.....

 

Yeah, no real way for them to tell. Unless you mangle something trying to press the pulley on or off....already saw one guy on the RL forums destroy his supercharger doing that. Bet warranty didn't save him on that one!!

 

Sounds good. Yeah when I had my mustang carmax tried to void my warranty because I had longtube headers.....when the problem was a cracked intake manifold. Of course, the magnusson moss act worked wonders in that situation. Glad to see some dealerships are a little more lenient on the mods.

 

if your using a modular pulley setup it will be extremely easy for them to tell, hmm what are all these hex bolts on the sc pulley, that wasn't there before.

 

Taking aftermarket parts off your car in order to have the car fixed under warantee is fraud; it is illegal and you can be convicted and punished for it. Not only that, but it just drives up the cost of cars and warantees for the rest of us. Don't commit warantee fraud. IF the aftermarket part you added is the cause of the problem then YOU need to pony up the cash to fix it, period. Don't like that? Don't mod your car.

Now, having said that, just because a part was added to your car doesn't mean that it voids your entire warranty. In fact the law even states that the dealership/manufacturer has to prove that the part added to your car caused the problem. And you can fight if the dealership refuses warantee work because of a part added to your car... but you need to be smart about it. An aftermarket SC pulley likely won't have anything to do with your air-conditioning not working. An aftermarket exhaust won't cause your power windows to stop working. However, an aftermarket SC pulley *could* be the cause of an engine failure.

I've had my car in twice for warrantee work. I've taken it to the dealership WITH aftermarket CAI, WGA, MBC, 3" Exhaust, BOV, etc... installed. And the dealership performed the work without question. Once was for a fraying Throttle Cable, and once to replace the seat back as there was a peice of foam missing. Even when replacing the throttle cable, the dealership had no problems with it.

Do yourself and your fellow car enthusiasts a favor and be honest about your mods and if you can't afford to fix something that could be caused by your mod, then don't mod.

 

Just FYI for you guys concerned about the warranty . GM tech2 is more sophisticated than you may think , and so is OBD2 . If you had any issues due to higher than stock boost levels , Im about sure they could track that with techII . I dunno if you pop the factory bypass valve if it sets a high boost level code or not , if it did Im sure it would be a code that would not set a ses light , but WOULD show up in code logs if the car had to be scanned . Some of the new GM OBD2 pcms have the ability to see conditions when a particular codes are set .

Dealers arent clueless

are just a few the possible codes higer than stock boost levels "may" set no chages made to the stock pcm tuning . Not all of them will set a SES light . Alot of codes like that are hidden . So say you have a dumb problem with the security system and go in to get the car scanned , the set codes you dont knw about are seen . Whether they would do anything about it , who knows . Point is , they would be able to tell higher than stock boost levels if they wanted to pursue it

 

I see, thank you for your informative, yet arrogant and snide reply. I appreciate that. Besides insulting my intelligence pertaining to legal situations, and in particular, the magnusson moss act, you failed to answer my direct question...which silver SS/SC so graciously did. I do not plan on bringing my vehicle in for any engine/drivetrain problems as I am mechanically enclined enough to fix my own problems. Perhaps, if I were to explain my situation to you, you wouldn't be so quick to judge....though it looks like you already have.

 

Don't be so quick to ASS-u-me. My post wasn't necessarily directed at you. I offered up some generic information for everyone that reads the thread, the same as I have done on other forums. There are alot of people out there that have no clue what the Magnusson Moss act is, or even that taking off a performance part to take it to the dealership for repairs is fraud and criminal prosecution is possible.

Seems like every board is filled with people that DON'T know and try (many with success) to get items repaired under warantee that were damaged due to performance parts by taking off the performance part before service so the "dealer doesn't know." And some even scream bloody murder when a dealership won't warantee repairs because of their mods.

And if you're going to do the work yourself, then why are you asking "Is there anyway for the service department to find out if you used a smaller pulley if you were to remove it and swap the stock one back on before taking it up to the dealership?" Sounds to me like you're wanting to keep the dealership in the dark about your mods and that is fraud.

 

Hey no problem, I'll be the first one to take back my words, I was thinking the whole post was directed towards me. I apologize. Basically my situation is I ordered a 3.25 pulley and it came in this morning; however I have to bring my car up to the shop on Friday due to the "infamous" rattles that have come up in many of the CSS's. Knowing that the person driving my car to pin-point the rattles is probably going to be a little "throttle-happy" (if you saw the teenagers working in the service area you'd understand lol, I think they all drive modded LS1's). Basically I don't want them to end up toying around and chancing them bringing up the whole "our service tech noticed you have done this/that to your car, you do realize you have voided your warranty...etc" crap (happened to me at Carmax, which is when I learned what the M.M act was. It took what was a simple intake gasket leak, into a three month legal battle about my 4.10 gears...that have nothing to do with the motor.. on my mustang). I was going to take the pulley off and put the stock one back on to avoid the chance confrontation.

 

I don't think the pully tool sfph sells to put on the pulley hub on would be able to take it back off, because the replacement hub is smaller than the original pulley.

I don't see how any of the installer tools I have looked at would be able to.

 

couldn't you just reset you pcm before you or when you got the the dealer, buy disconnecting the battery and then, pressing the brake to take out any other power that is left.

 

To remove the DUB Hub Assembly, you will need our DUB Hub Removal Tool, to work with the Pulley Puller Tool, to remove the DUB Pulley Unit completely. Hope this helps, as here is a link to the tool.

IMPORTANT NOTE: You DO NOT want to attempt to remove the Hub Assembly with the DUB Pulleys attached to it, as it will distort the SC Pulley as you attempt to remove it. You MUST use the Dial_Ur_Boost Hub Removal Backing Plate to safely and easily remove the DUB Hub. We sell the Backing Plate separately in our Products section.

 

There should be a sticky post on warranty...

WHy is it that people think a Mod voids the entire cars warranty....

A cars warranty is for the whole car and can only be broken if you affect something directly. For example.. if you put a cat-back on your car, dont bring it in for problems with your exuast. BUTTT if your AC stops working and you get a leak in the window, thats what your warranty is for.
