Does anyone know the part# for the wastegate actuator? I've been talking to a few cobalt SS owners...and they seem to think it's the actuator. BUT....I can't find a part number anywhere.......

 

IIRC I don't even think that part is availaable through Gm

 

what is "IIRC"?

 

If I Remember Correctly

 

Removed the wategate actuator...

Looked it over for broken vacuum nipples...looks fine
Cleaned the electrical connector with electrical cleaner
Blew Air through it
Shot 12 volts of power to it...and it makes a "clicking" noise...I'm thinking it's working fine.
Put it all back together....no change...exactly the same. Guess it's time for that reflash...

 

Did you get the cable with your trifecta, I'm new at this, I just did my first data log, that was fun, 2nd to 3rd especially. The stock tune came with mine, is that how you are flashing it ??

 

I went ahead and rented their "GT Tuner"....it's a hand held unit that plugs right in.

I have to take it to the dealer so they can "reflash" the GMS1 tune...which will delete the Trifecta Tune.

 

For you guys wanting the GM Part Number for the Turbo Wastegate Actuator....I found it..after searching online for about 5 hours.

Part# 19168559
It's available through www.gmpartshouse.com & is about $150 bucks plus shipping

 

Update......................

Talked to the dealer today.....
They automatically thought it was the nuts on the wastegate rod...they thought they were out of adjustment. I told them...if that were true...it wouldn't be sporadic....

Then I told them about the wategate actuator solenoid...
I could tell that the gave a sh*t...but they ordered one for me. They told me to keep it on the downlow...and once I install the new actuator....to give them my old actuator...and they will put it under a warranty claim.

So...atleast I'm getting something done...

 

Thats great they are working for you. It seems like they should be telling you whats wrong, but at this point, any help is ,... help. I sure hope it straightens it out, we will all have to stash one of them, just in case.
