darkseed Posted February 16, 2004 Report Share Posted February 16, 2004 About a week ago I purchased my 160 thermo an hypertech 1014. After reading previous post and namely one by member a1cmaw I noticed that this was the model being installed on the 03 ss. I went to install mine just after recieving custom tune and it does not fit. The two outer post that come off the main housing that retain the spring are to wide.....by about an 1/8 of an inch. Has anyone with an 04 ss installed a powerstat....? which one did u go with? Is it poss that this has changed from the 03......seems strange thanks Dave Link to comment Share on other sites More sharing options...

BenKey Posted February 16, 2004 Report Share Posted February 16, 2004 I bought a 160* powerstat from Tbyrne. Didn't have any problems. Unsure of the part number. If you got one and it didn't fit, then I would think you didn't get the right one for our engine. That would mean that the water pumps would now have diff part numbers if there was a difference in the thermos. I could be wrong, but I don't think they changed between '03 and '04. Where did you order from? Link to comment Share on other sites More sharing options...

blackhawk Posted February 16, 2004 Report Share Posted February 16, 2004 darkseed, That should work in your truck; they may have shipped the wrong one to you… Go to this link and click on ignition and scroll down... Powerstat Link to comment Share on other sites More sharing options...
darkseed Posted February 16, 2004 Author Report Share Posted February 16, 2004 yup thats the one they sent me 1014 ....and no fit. My mechanic and I checked and rechecked and it would not fit thats why I am wondering if any 04s have tried to put in a stat Link to comment Share on other sites More sharing options...
blackhawk Posted February 16, 2004 Report Share Posted February 16, 2004 darkseed, Hmmm, sorry I can’t help. BTW, your truck is missing a nipple… Nice ride, my windows are blacked out as well, makes it a Bi@ch to see at night though… Link to comment Share on other sites More sharing options...
SuperSport Posted February 16, 2004 Report Share Posted February 16, 2004 I just ordered a 180 thermostat for my truck that is a hypertech i hope mine fits, i have an 04 as well. Link to comment Share on other sites More sharing options...
Jspeeddemon Posted February 16, 2004 Report Share Posted February 16, 2004 I understand that they changed the housing size on 04 corvettes as well so 03 thermostats will not fit in 04 corvettes either, you may wnat to investigate farther to verify.

BigTex Posted February 16, 2004 Report Share Posted February 16, 2004 After I posted the stuff on how to modify your stock thermostat, I tried the same thing on my SS. As it turns out, GM changed the way the Tstat is configured on the inside and a BB no longer fits. Plus, the stat was more difficult to work with. Fortunately, I had another "older" stat off an 02 truck. I did the BB mod on it without issue. As far as it not being as cool as a hyperstat160, well I think its actually cooler. At moderate speeds without my fans coming on, temps usually show low 170s with EFI software and the gauge needle is in the 180 range. Link to comment Share on other sites More sharing options...

The stat off the '03 SS did not work with the BB mod. I used the stat off my previous '00 5.3L Silv with BB mod and it worked fine. My coolant temps stay between 160 and 180, depending on the weather. Unusual if GM changed the stat from '03 to '04... Link to comment Share on other sites More sharing options...
onelow04 Posted February 17, 2004 Report Share Posted February 17, 2004 I just found this out also after dumping my antifreeze out! I installed my hypertech pp3 and went to put in the thermostat and it wouldnt work.(160 degree) I called hypertech and they said that they dont have a powerstat out yet for the 04 chevys because they were not aware that they had changed from 03. They said that one of their customers had went to Autozone and bought a 180 degree for an older truck (without housing)and it worked but Hypertech has not tried this yet. They also told me not to go as cold as 160degree on the 03/04 trucks, to go with a 180degree thermostat if you can make a regular thermostat work. The sad part about this is that if you call Stylin,or Summit they will tell you that the powerstats will work on the 04s but they are not aware of this problem either.

zippy Posted February 18, 2004 Report Share Posted February 18, 2004 looks like i need to do some part number research at work tomorrow and possibly order a stock thermostat for an 04' to see what can be used. Link to comment Share on other sites More sharing options...
