Changes: Engine Oil PressureSwitch+Needle

Revision as of 16:03, 21 August 2021

This V6~4.0L~SOHC has an OilPressureSwitch only, not a true variable Sensor; it toggles Off~On @6~8psi;
despite appearance, the InstrumentCluster OilPressureNeedle is Off~On only; it's not a true variable Gage.

EngineColdStart Procedure

If V6~4.0L~SOHC Engine hasn't run for 12 hours or longer, this EngineColdStart routine is recommended
for general PreLub of the Engine critical components & specificly to PrePressurize the TimingTensioners.

Turn Key To RUN Not START, Let InstrumentCluster Lamp+BuzzerTest Complete
Push+Hold GasPedal To Floor, InstrumentCluster OilPressureNeedle Should Be At Zero
Turn Key To START, Let Engine CRANK Without Starting Until OilPressureNeedle Moves Or ~10secs
Let Key SpringReturn To RUN, Engine CRANK Should Stop
Release GasPedal, Turn Key To START; When Engine STARTS, Let Key SpringReturn To RUN
OilPressureNeedle Should Quickly Rise+Hold At MidGage Position
