This morning I started my car and headed to work. The engine temp slowly got up to the middle, optimal range (3 bars) and stayed there for about 30 minutes. Then one bar drops off (down to 2 bars) signifying that the engine is now running cooler. It stayed this way for the remaining 15 minutes to work with the engine staying mostly around 3k RPMs at about 60 mph or so. Any ideas why it would run a little cold? Ran fine, no problems.... 30F outside.

 

Cause it's cold out silly pants..

 

I'm thinking my engine would still run at normal temperature... tell me if i'm wrong, i've never noticed my engine running colder in another car during the winter. HOwever, i've never had a digital readout for engine temp. either, its always been a needle, so I have no idea how much temp. difference that largest digital block represents.

 

I don't know what done it for but after i replaced the header my temp stays at 2 bars all the time that is the normal operating temp

 

Well, from what i hear from other sources, 4th gen temp. gauges aren't the most accurate, i'm guessing b/c of the digital aspect..... but it seems this is normal and within safe conditions....

 

did you have the fan/heater on? if you have the heater on I find that it will suck out the hot air and make the engine run a lil cooler.

 

in that cold of weather you should be fine running a little lower, just watch out when you start running hot. Then come back and worry. Brrr... 30 is cold, it was 23 out here today.
