Anyone here put a 160 deg thermostat in their '03 or newer? If so, do you need to have a programmer, or can this be done to a basically stock engine? Also, will the hyperteck 1014 thermostat work? I've checked out a couple of different websites selling them, one site only sells the 180 degree thermostat for the '03, and the other two websites conflict on what years the thermostat is for. One site says that the thermostat will work in a 99+ silverado, while the other site says it is for a 97-99 silvy. :rolleyes:

 

Thanks in advance!

I know a guy that has an 00 5.3 and he runs the 160 t-stat, but has the Hypertec Power Programmer.

 

I wouldn't put the 160 in a stock motor. I would not go lower then 180 with a chip/programmer and 190 in a stock engine. This is just my opinion.

 

When you run the motor at a lower temperature, with the computer not setup for it, you will get worse fuel mileage and running cold is not the greatest for the motor.

 

The real advantage to running at a lower temp is to avoid detonation, but if you don't have advanced timing(like what the programmer does for higher octane) then there really is no point to it.

O ya, how do you like the K&N FIPK? Worth the money?

 

How do you like the 40 series? Nice tone to it?

 

Thinkin about doing the same to my truck.

I'm running the 160 with a aem brute force induction and no other mods. I ordered it from summit racing equipment. I didn't experience in decline in gas milage as well. If you look at an obd II scanner, you'll notice that the truck goes into closed loop at 133 degrees. So does my dad's '04 suburban. I can also tell you that my friend with a 180 degree t stat ran 185 degrees normally and when he changed it over to a 160 degree t stat he still ran 185 degrees normally.

Hmmmm...

 

Interesting

 

The 40 series definitely sounds great. Have a 50 series on my Jeep with a 318 and it is a little quieter then I would like.

 

40 Series sounds like the answer.

I agree with this and the use of a low temp one will hurt fuel mileage too as well as allow more moisture build up in crankcase in stop and go driving in cool weather too. It is not worth it. A 180f would be as low as I would go and I use 190's .

      This is a really late reply but I just found this thread. They won't sell the hinges. I've gone 7 rounds with them. Their solution is to buy a new cover. I'm about to buy a new cover and it won't be a Bakflip. It also won't be from realtruck.com.

      2 speed transfer case optional now?

      By Chuck FB · Posted

      Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver.

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      By Chuck FB · Posted

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.
