...I would hope they teach you more as you go, the current EFI strategies are based on sensor data and time, not mileage.
Remote start doesn't do anyting for your vehicle, it is a "convenience" feature that wastes gas. Your speed in the driveway with no one behind the wheel is 0 and the engine is running, therefore your MPG is 0. The owners manual says to drive the vehicle immediatley after starting to warm it up and increase economy.
The 3.0L engine is equipped with a "bypass loop" in the cooling system to reduce circulation noise as reported in the 1994 (ish) TSB. This is a warm loop that by-passes the thermostat to circulate coolant 100% of the time through a 5/8" hose starting at the lower (cold) hose and going to the intake manifold, before the T-Stat.
The water pump pulls cooled water from the lower radiator hose and forces it in the front of the block, from here it goes to the rear of the block (the vast majority of it) enters the heads at the rear and moves forward to the intake manifolds water riser, to the T-Stat housing and NORMALLY to the hot side of the radiator (top) through the upper hose. The bypass "jumpers" the hot side to the cold. The mechanical fan turns all the time, bring colder outside air over the radiator. Since cold water sinks, this water is now picked up at the input to the bypass and run through the engine.
With an electric fan, no additional cooling is added at idle, so the water is continuously warming. I also deleted the hot water bypass and used a full flow t-stat with a small hole drilled in it instead. Worked great, warmed up very quickly, removed 3 ft of useless hose, 4 clamps and made the front of the engine look much cleaner. Hoses changes are much easier too.
Been there, did that, recorded the results.
