The o2 sensor fuse was in the fuse box.

it sounds like you guys are making too big a deal out of the 180* t-stat... it is not. all it does is open sooner and opens to full flow sooner than a 195* t-stat. you will not throw a code and you will not have any adverse affects from the swap. DC puts a 195 stat in there for emissions purposes... a hotter motor runs cleaner at the sacrafice of performance...

 

Well i replaced mine with a 195 and the engine runs significantly below its old opperating temp. Before i only used strait coolant in the radiator but now its got around a 60% 40 % coolant to water ratio. i dont know if this would cause the change in temp but should i worry about anything with the cooler temp? i havent noticed any performance difference.
My truck has a sputtering problem occasionally and it seems to be occuring more frequently not that i changed the thermostat but that could just be a coincidence

 

I have to flush the rad and was going to put a 180 in now i'm not sure.

 

Straight coolant is a great way to damage your engine and cooling system.

 

Sorry, but I beg to differ bro.

After I installed the 180 I kept throwing a code, each time related to the t-stat, in winter. 3 X $25 a read and it was gone.

 

I've read in warmer climates like Texas, southern Cali, Florida, etc., the 180 t-stat works just fine. However, up here in the midwest and other places where we have pretty cold winters (and other places that have even colder winters), the 180s sometimes cause CELs. Don't think I actually have heard of any real problems related to the t-stat other than the CEL, though.

 

my 160 hasnt given me any problems other than being stuck in open loop, No CEL`s no nothing. And ive ran this for a year now , through the cold winter.

 

I still haven't got an answer that makes any sense what the benefit is of running a 180 degree t-stat. It seems to me the risk of carbon build up and poor combustion from the lower temps would be more of a risk than any gains you would get.

 

I'm in Southwes Texas and have no issues with mine; however it may be different up there where you boys are with all the snow and stuff.

 

I installed the 180 T stat two weeks ago, and i drive about 400 miles a week, the truck runs better with this T stat and there is no difference in mpg, so i love it so far, no worries of over heating just drive the truck and last week i was in a big traffic mess so i had to drive 2 miles per hour for about 15 miles, and the truck stays at 180.
