Factory manualTaken from a Mazda factory workshop manual, with page citation.

Procedure

Check with engine cold or at least 30 min after stopping. New means run for less than 5 min. Apply 98 N {10 kgf, 22 lbf} midway along the generator-to-crankshaft span or the power-steering-to-crankshaft span, as appropriate. Applies to power steering with or without A/C; does not establish an A/C-only belt setting. The actual 2005 engine technical-data table explicitly includes BP and BP WITH TC; the displayed setting applies to both.

Applies to

NB 2001–2005 (BP-Z3) — Other years inferred from 2003 factory evidence.
NB 2004–2005 (BP-Z3-TURBO) — 2005 factory technical data explicitly includes BP WITH TC; 2004 inferred within MSM family.
