Description

Full size extended cab pickup truck with a fuel injected 5.7 (350ci) V-8 , 4 speed automatic overdrive tranny, and electronic pushbutton 4wd. I just hit 150,000 miles in May of 2008.

Z71 Premium Off Road package, ps, pb, at w/ OD, pw, pl, ac, remote keyless entry, cc, tilt, electronic 4wd, digital compass, auto dimming mirrors, power mirrors, power seats w/ lumbar, Factory towing package with upgraded oil and tranny coolers, AM/FM/CD/Cassette. Pretty much all factory options except the 6 disc CD changer and leather seats.

Since I have purchased the Hybrid Escape, this vehicle has now achieved "Beater" status, and probably won't be driven much anymore.
Modifications
7/10/2008 ScangaugeII w/ xGauge installed

8/10/2008 Air Dam Extension. (http://www.gassavers.org/showthread.php?t=8727) Picked up an airdam from a 2wd Chevy Tahoe @ a U-Pull-It junkyard earlier this week. I flipped it upside down and bolted it to the bottom of the airdam on my truck. Total cost: $10 Installation time about 30 minutes. Hopefully this will net me some extra mileage. Can't wait for some highway miles...

8/28/2008: Experimenting with leaving the lid off of the air cleaner housing so the engine pulls warm air from the engine bay instead of the factory intake. In city driving I notice temps 30 degrees over outside air temp, and @ 55 MPH I noticed temps of 15 - 25 degrees over ambient. Still not a WAI, but a good start that took less than a minute to do.

8/30/2008: Stealth grille block installed. http://www.gassavers.org/f11/stealth-grille-block-installed-in-the-beast-8927.html I blocked the grille with black plastic from a flattened out trashcan. I then took a holesaw and made a 4" hole right in front of the oil and tranny coolers. Hopefully this is all the airflow I need. If it gets too hot I'll add another 4" hole. I really don't think I'll need 2 holes though.

8/31/2008: Installed new OEM plug wires. Turns out that the truck is almost 11 years old with 150,000 miles and it still had the original plug wires installed. Inspected cap & rotor. They were fine (I expected as much, there was only 30,000 miles on them) Didn't bother with the plugs since there was only 30,000 miles on them and they are 100,000 mile platinums.

9/1/2008: Road tested grille block 80F ambient temperature, max water temp was 208. IAT had risen to 140 - 160. I will add another hole in the grille block as I do not feel comfortable that it will adequately cool in 100 degree heat.

9/3/2008: Added a second 4" hole to the grille block.

9/7/2008: Experimenting with removing the aerial radio antenna, but I think with the bulk of my driving being short trip city stop & go it probably won't make a difference.

9/10/2008: Michelin LTX A/S "E" rated tires @ 70 PSI, alignment, and a bottle of BG 44K added today. (http://www.gassavers.org/showthread.php?t=9033)

9/28/2008: Oil change. This time I tried Mobil 1 0w30 instead of my normal Mobil 1 5w30. I also tried the Mobil 1 oil filter instead of the regular Fram filter.

10/2011: Scangauge removed and installed on my Escape.
