GM Throttle body service.
Hello, I'm calling in for an oil change in a couple days time and the service person at my dealer recomended a throttle body service for my 2010 SS at 50,000km. They really tried to sell me on this, but I declined until I research a little info on here from you guys. They also said it is recomended but not mandatory, I'm assuming this won't hinder my warranty if I don't get it done.
Question is what does this service entail? Are they just going to clean out the TB by hand or use some sort of "GM" seafoam? They were asking $56 I believe.
There's been a bit of Seafoam talk lately and I've watched the video recently posted, seems very easy to do myself.

They will probably just use some sort of TB cleaner. Usually they will sell you fuel system service. What they will do though for that is just take off your intake tube and start the car and spray the TB clean at the TB from what I've seen.

What exactly is entailed with Cleaning the TB on the LNF? I looked for some writeups, but couldn't seem to find any. From what i've read it is alot of work like you said.

But on a turbo car you can't obviously do that.
They would have to remove the lower charge pipe and remove the throttle body and clean by had. There is no safe effective way to clean it on the car.

They're probably trying to sell him an induction flush, which is like a seafoam treatment. No need to remove the TB. Some of you are being just as ignorant as you claim the dealership is.
Carbon deposits are a real problem on newer cars because of emissions, fuel additives and crankcase ventilation. Sure you can do it cheaper than the dealership, but you don't have to worry about paying for overhead, insurance, wages, etc...
You definitely should "safely" clean your TB every 20-30K to help resolve potential idle issues. On some vehicle, I've seen customers come in with check engine lights and pay diagnostics to find out they have throttle body performance codes set due to carbon deposits and resolved by an induction flush. There's nothing wrong with doing it yourself, just make sure you know what you're doing before you do it so you don't screw anything up.

Okay so from what I've got they would never do a TB clean due to cost/time, must just be a seafoam type of cleaner along with a gas tank additive, judging by the $56 cost. Are gas tank additives more/less effective on a DI engine?
This dealership is pretty good to me. I always have the head mechanic doing my work on the Cobalt (unless it's reg maint) He even did the Supercharger install for a 2.2 ecotec on my last car, 0 problems. Also there's a salesman there with an 08 SS/TC and he's went through the light mod stage (tune,intake,dp) so i'm hoping in the long run lessons learned from that car transfer over to mine
I haven't done a seafoam but come spring I think I will. Question is, how much does carbon buildup have an effect on performance? If 2 cars were dyno'd @ say 50,000km, 1 had been seafoamed a couple times, and the other never. Would there be a noticeable diffference on a dyno? Let's say this equation is doubled @ 100k, or even 150k, would the end results be visible on a dyno?
Thanks for the responses thus far.

Well i think you would see a little improvement with seafoam over time. The build up can cause issues like valve seating which will lead to lower compression and power. For sure needs to be done every 10k miles
In the gas tank won't really clean injectors and such though. High pressure pretty much prevents that.

if you drive like an old fart then you could have carbon build up gm doesnt recommend it gm has a bulletin saying not to do fuel system services but the dealers still sell them cash grab because its all about gas milage and if they say it will improve gas milage of course they'll do it

My brake pads are needing to be changed very soon they said, Sitting @ 56,000km. Also I'm thinking about doing Coolant/Tranny fluid, but would like to wait till spring.
