What I meant was the tstat by itself without the switch. :D

 

I am not good at judgeing if you are serious. But to answer seriously, it's alway's the combination of parts, not the part. Ric

 

I'm serious Ric.....see I can put the tstat in but don't know how to put the fan switch in:D

 

It's not how many years you've run with the 160 it's how many miles. I've had 7 Corvettes and each has had an average of 47K miles per year. Two of those had the 160 thermostat. If you want to know what happened to those two at 60K and 73K miles email and I will tell you. I'm not going to get in a P-----n match on this thread but be carful on how and why you mod.

 

I know what you mean. I've had two different dyno days, a year apart, with three pulls each time and this is what I got...and the mechanic said my car was running too hot...even though the later dyno runs (all three within probably ten minutes) sometimes showed more horsepower. So what does it all mean??? I guess there is some error factor to be considered in the dyno too.

1st Day HP/TQ 291/293 297/323 296/310

2nd Day (a year later) HP/TQ 298/302 292/298 295/301

Oh yeah, by the way, this was without the Blackwing, power duct, and MAF screen removal listed in my sig. I am going to do the MAF translator (probably my last mod) and get it dynoed again this Thursday and see what I come up with. I'm going to be pretty irritated if I don't break 300 hp this time around..!!! :yesnod: :yesnod:

1st off, not intending to enter a urinating contest, just my take below :D

On average, my LT1 only runs about 10 - 12 degrees cooler using the 160 tstat. Granted I use fans on at 213 off at 205, because the lower settings make the fans run continuously. Oil temps get up to the usual ~212 range as with the 180 tstat so crank case moisture boil-off is not reduced w/ the 160 vs. the 180, not in my sled at least. My instant mileage and avg mileage have stayed the same. Because although it runs 10 - 12 F cooler, the temp no longer climbs to 230 in traffic like the stock GM programming let it. What I am getting at it is that the heat range fluctuation is slightly reduced from the stock condition. Stock condition in city driving: 205 - 230 degrees range = 25 F routine temp fluctuation. 160 condition w/ fans programmed as above: 194 - 212 degrees = 18 degrees fluctuation.

Based on these numbers I am seeing with my car, I cannot see how the 160 can make any long term negative impact on engine longevity. Granted I don't run the fans as aggressively as some do, but then I don't want them running continously. I tried a fans on/off setting of 185/176 and they ran all the time which I didn't care for-- wear them out faster and also the alternator.

Gary, YOU can get the fan to run at the track, here is the quick fix, pull realy 43 out of your under hood fues,realy box. carefully "pry the plastic cover up and off, when it's off use a nail file on the small tabs so it will be easy to remove the cover next time. Put the realy back in with the cover off, you will see it has a butterfly switch, if you push it over the high speed fan comes on. Take a piece of card board or folded paper, put it inbetween the butterfly and tab to hold the switch back. When you see it, it's simple. My advice is to pay someone to put a realy and switch in, but this will get you the same result. In FLA your car will run 178-85 with a 160 when moveing and the same as stock in trafic. Ric

 

I just turn on the AC before the run, my fans come on with it.

 

Ric thanks for the heads up.Right now I run between 194-212 in traffic.Just curious....I have access to a Tech 2.....can it reprogram the fans to come on earlier? Thanks

 

I haven't had access to a tech II but it woulden't suprise me if it could. It also woulden't suprise me if there were differant versions available depending on who you are, and where you get one. Ric

 

Ric I will stop by my dealer tomorrow to see if it can.....The service manager is very cool and will do it if possible.

 

I put mine in over six months ago because the car was getting up to 230 on a regular basis. I added the new thermostat and I never get above 215 and there only rarely. INcluding at the track. When I had the PCM reprogrammed, I had them allow for the new thermostat.
