Hi all, I'm looking into putting in a 160 degree thermostat ....got a few questions:

1) I've got the manual and read about replacing it ...but in real world terms ...how hard is it to do?

2) How much of a difference does this mod make?

3) Do I need to get re-tuned again ...and spend umpteen days hoping to hear back from Charlie Wheatly ...great results, but don't get me started on his customer service. lol

 

Not hard at all. You will need at least 2 gallons of fluid to replace what falls out. When I changed mine I removed the air intake, unbolted the cap(located on the passenger side front of the motor), Killed the grass under the truck, and installed the new T stat.

I did many mods at the same time....I don't know about performance......Ultimately, a cool engine is a healthy engine.

Retuning may be nessesary because you have electric fans. The sensors will need to be adjusted to turn on your fans at a lower temp.

Also, I went to 180 not 160.....I am Hypertech programmed and the program does not go lower.

 

Going to 160 isn't worth it anyways when you consider gas milage (an d emissions if you care). 180 allows the engine to run cooler but still keep it in a healthy operating temp range to get good power/mpg.

 

So,it sounds like the160 would be counter productive.... back to the auto parts store. lol

 

Nascar - optimun operating temp......210!!!

 

A couple guys on here use 160 t-stats, and have had no issues and alot of improvement, you may want to check with popo or MrLM7, I can't remember which.

As far as what nascar uses, they are also running 800 HP

 

I got the 160 degree thermostat and have had no problems with it, but i do live in Mass. and havent tried to pass inspections yet....

 

A cooler engine uses more fuel

 

I talked to one guy on CarDomain who has the 160* thermostat in his VHO and he said there is hardly any differencein normal operating temp and performance. He said it wasn't worth it.

 

a cooler engine is NOT more efficient? Is it the density factor?
