Home Depot'd my CAI and dropped my IAT 20 degrees!

Looks familiar, I just paid more

There is a reason 99% of cars come with 195* t-stat

1. Engine needs to warm up to run properly.

2. Computer never comes out of "cold start warm up" mode.

Never run lower than a 180* t-stat.

i call BS on that since closed loop starts at 92 or 94* on these motors. if the motor is tuned properly for it, its not going ot hurt it. the reason they put 195 in for proper burning of fuel for everyday vehicles and emissions

My truck is tuned. I'm not trying to run the truck at 140* or anything. Just wanna keep it around 180*. If it gets colder than that i'll put in a modded thermostat. So far with no thermostat the coldest it gets after getting up to temp is about 190*.

You might have an issue as mine has a 160 in it and barely cracks 175 if ever. Then again, no tstat can make one run hotter because the coolant doesn't stay in the radiator long enough.

Closed loop starts at 153 degrees. Put too low a tstat in and you'll get P0128. With add on OEM efans and a 160 mine will set this code in the winter when the auto AC turns on the compressor and therefore the fans and the coolant never get warms enough for closed loop hence the P0128.

I would not say never go below 180 'cause a 160 does have a proper application but my 160 needs to be a 180 and I WOULD NEVER RECOMMEND NO TSTAT TO ANYONE for a driver, only a track only, TRACK ONLY vehicle.

i just looked up a stock tune file for a 02 4.8 silverado and closed loop is 131*

There is also a reason all cars come with catalytic converts too.
Like i said right now my truck is running at about 190*. Which is just about where i want it 180-190.

[GasGuzzler]

DTC sets on ANYTHING '96 and newer if ECT doesn't get to 153 in a certain time so we're arguing two different issues. But then again, 13X is too cool for optimum performance especially with heat shedding aluminum heads.

[SUX2BU]

the gauge doesnt show actual temp. my gauge reads about 170 and i cruise around 150

your gauge might show 195-200 and actual temp will be 215

All my readings are using a GM Tech 2.

No offense man but that means you need a 180 tstat as described.

[CHEVROLADE]

looks nice,
would a plastic intake stay cooler than a aluminum intake?
