Line Pressure Adjustment
WARNING: This page is about a different car, the 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
Measure distance from the valve body to the inner edge of the adjusting screw with an accurate steel scale (Fig 1).
Distance should be 33.4 mm (5/16 in.).
If adjustment is required, turn the adjusting screw in, or out, to obtain required distance setting.
NOTE:
The 33.4 mm (1-5/16 in.) setting is an approximate setting. Manufacturing tolerances may make it necessary to vary from this dimension to obtain desired pressure.
One complete turn of the adjusting screw changes line pressure approximately 1-2/3 psi (9 kPa).
Turning the adjusting screw counterclockwise increases pressure while turning the screw clockwise decreases pressure.
