160 thermo

[VinPecora]

I have a stock ty with a hypertech thermo master, and 160 thermo stat, My temp guage hasn't changed much,actually on the high way the temp goes up past half way mark, my sy has a ATR chip , and ATR 160, and the guage stays way down. :roll: What Do I do?? Thanks

Alot of trucks read differently when they may be much closer than they appear. I would get a datalogging tool on both trucks and get the real temps.

Another easy fix would be to pick up a 160* thermo from the local parts store and put it on the Ty.

I had a 160* thermo in my Ty and temps would stay at 160* - 168* all the time. Turn on the AC and it would climb up just a bit, but nothing big.

Let everyone know what you find out...good luck.

I also have 160 with the same results, I like the 160 alot better than the 180 that was in there before.

it's cool to run cooler...

Go to Autozone or the like and pick up a Robert Shaw generation one 160 thermostat for less than $10. Just a word of caution though if you live in an area where you have to be checked for emissions. A cooler stat will make it harder for you to pass. So a swap to the stock stat may be required when you go to get tested (if ever) HTH.

I have the 160 thermo too with an electric fan (thinking of adding a light weight flex fan at the same time, too cool it down more and make a little noise) anyway, i ran emissions and passed with flying colors... they watched my rpms and shoved that stick up my ty's ass..... oh well my .02 with the low temps...

I was looking at the Robert Shaw thermostats at AutoZone the other day. I noticed that they have a few different 4.3L versions listed. Is there really any difference, and if so, which one do I want? Are there any possible negative side effects of going with a colder stat? Gas mileage, incorrect computer readings, etc.?

I ran a 160º this winter and since I only drive 2 miles to work, I was getting alot of condensation and fuel dilution in my oil (based on an oil analysis). I would recommend switching the 160º for a 180º or 195º during the winter.
