30-June-2010: WAI added.

30-June-2011: Installed underdrive pulleys for crank & waterpump. Replaced rear shocks and front sway-bar end mounts with Master Pro K80066.
//*note: June-2011 The driver-side rear tire has been making noise due to a jagged wear pattern caused by a failed shock absorber. I recently replaced the rear shocks, but this tire still makes noise and adds extra rolling resistance accounting for a slight decrease in mpg. The switch back to regular motor oil also showed a slight decrease in mpg in comparison to the 0w-30 mobil-1 synthetic.
The underdrive pulleys have increased the operating temperature of the coolant back up to the normal factory level of 210* - 230*F. -end note.//
