This TSB is being republished to provide current service part numbers for the dipstick cap and baffle.
Power steering pump leaks which appear to originate at the pressure fitting, return fitting, or at the reservoir to housing seal may actually be caused by fluid spilling past the dipstick/cap assembly. Overfill is the most common cause of spillage. Also, vehicles with high performance engines such as the 5.0L H.O. and the 2.3L EFI turbo are more susceptible to spillage. Other vehicles may spill fluid due to rough roads or severe handling conditions.
Figure 1 - Dipstick/Cap Assemblies:
A new center vent dipstick (Figure 1) has been released to prevent spillage. It includes one additional baffle, a deep set "O" ring, and a 3/16" lower fluid level. For high performance vehicles with a 5.0L H.O. or 2.3L EFI turbo, a separate rubber baffle is added to the dipstick.
Before installing a new dipstick/cap assembly, make certain that spillage was not caused by an overfill condition.
1. Check return line at the pump for looseness and tighten clamp as necessary.
2. Check fluid level with new dipstick and adjust fluid level between "add" and "cold full" with fluid at room temperature.
3. If it is a high performance vehicle as noted above, install baffle on dipstick as illustrated in Figure 1.
NOTE: A gap between the filler neck and the cap is normal on reservoirs originally using the old dipstick. The deep set "O" ring compensates for this.
