Special tools are available from Mazda and other manufacturers for removng
retaining clips. Use Mazda Tools 49-UN01-053 and 49-UN01-054 or equivalent.
If the tool is not on hand, go onto step 2. Align the slot on the push connector
disconnect tool with either tab on the retaining clip. Pull the line from
the connector.
If the special clip tool is not available, use a pair of narrow 6-inch slip-jaw
pliers with a jaw width of 0.2 inch (5mm) or less. Align the jaws of the pliers
with the openings of the fitting case and compress the part of the retaining
clip that engages the case. Compressing the retaining clip will release the
fitting, which may be pulled from the connector. Both sides of the clip must
be compressed at the same time to disengage.
Inspect the retaining clip, fitting end and connector. Replace the clip
if any damage is apparent.
Push the line into the steel connector until a click is heard, indicating
the clip is in place. Pull on the line to check engagement.
