Watch your oil pressure as well.. I know mine gets pretty high when the weather gets cold. Takes about 10 minutes for the oil to warm up completely and for the pressure to get down to normal. When I'm first coming out of my driveway in the morning I usually can't get above 3500 rpm without the oil pressure going above 120 psi, so I just take it slow until everything gets warmed up.
When it is below 40 degrees outside. I turn on my car, wait for the oil pressure to build which just takes about 10 seconds. Then I wait 60 seconds and drive off slowly.
If you put your manual transmission in neutral and let the clutch out it while it is warming up and the tranny fluid will heat. That makes that first shift to second gear smooth.
Did this on my old 300ZX and now I do it on my 350Z. It just works really well on these cars.
When you take off drive easy for the first two miles or so. By then your motor and heater should be all warmed up and ready to rock and roll!

Okay, winter HVAC questions… You guys need a Canuck for that one (me!)
The A/C will dry the air even if it’s cold outside. It it’s important that it is on when you’re running in Recycle mode. Why? Just the humidity from your breathing can fog up the windows in winter. Worst, if it’s snowing you probably brought some with you getting in the car. The HVAC will scoop the air from the floor, where that melted snow is.
Once the engine is warm, go back to Fresh mode and enjoy a fog less cabin. I keep the A/C on most of the time even then.
You’re right about the lubrication part also.

I used to do this in all my previous cars to get the interior heated up faster since the interior air temp is warmer than outside fresh air. Now I have to wait till the engine is warm enough to cool the outside air b/c I refuse to have the compressor running during the winter.
Note: It is good maintenance to run the a/c periodically throughout the Winter to keep the seals lubricated. This may have been a secondary motive for Nissan.

Dont "They" always say anything over 1 minute of warm up time is actually hurting your engine.
It's the same thing with storing a car for the winter, some people insist on starting it every so often and letting it run for 10 minutes or so until the temperature is up. This isnt all there is to it, just because the engine is at operating temperature doesnt mean that all the condensation, contaminates and by products of combustion are getting exhausted completely.
Driving it is the best thing to do, as stated, once the oil pressure is up. Driving slowly for the first few kms/miles until the temp and idle is normal.
If you want things to warm up a little quicker, purchase or use your block heater.

. YES!
Back to the original problem. I have a 2003 Track. It is single digit temps in Iowa right now. When I come to a stop, long light, etc. the heater air goes cold. I've check to see if the antifreeze is low. It is at the Max line. Sounds like there may be a problem with the 2003s.
