APPLICABLE MODEL(S) / VINS 2001-2007 Truck / B-Series (2.3L Only) 2005-2006 Tribute (2.3L Only) 2003-2007 Mazda6 (2.3L Only) 2004-2007 Mazda3 (2.0L & 2.3L) 2006-2007 Mazda5 2006-2007 Mazda MX-5 2006-2007 Mazdaspeed6 2007 Mazda CX-7 2007 Mazdaspeed3 DESCRIPTION When removing or replacing the crankshaft pulley on a 2.0L (Mazda3 only) or a 2.3L engine, be sure to follow the Workshop Manual procedures. The crankshaft pulley is not keyed to the crankshaft, and when loosened, it may move out of position on the crankshaft. The engine MUST be re-timed whenever the crankshaft pulley bolt is loosened, removed, or replaced. For normal aspirated engines, follow the Workshop Manual procedures and time the engine using Special Tools (Crankshaft Alignment Pin 303-507, Camshaft Alignment Timing Tool 303-465 and a standard M6 X 1.0 X 2.25 bolt). For direct injection spark ignition engines, follow the Workshop Manual procedures and time the engine using Special Tools (Crankshaft Alignment Pin 303-507, Camshaft Alignment Timing Tool 303-1061 and a standard M6 X 1.0 X 2.25 bolt). Please refer to the Mazda Job Aid on MS3 under Training titled “Engine Timing Verification and Correction LF2.0L and L3/L3T 2.3L” for more information. CAUTION: Engine damage will occur if the engine is not re-timed properly. Refer to applicable Workshop Manual (Section 01-10 – MECHANICAL – 2.0L (Mazda3 only) or 2.3L). NOTE: Damage to an engine caused by not following proper Workshop Manual procedures may result in denial of warranty claims or back charges.

2004-2009 Mazda3 2006-2009 Mazda5 2003-2008 Mazda6 with L3 Engine 2006-2009 MX-5 DESCRIPTION This bulletin provides guidelines for repairing internal engine noise issues (such as Knocking, Ticking, Tapping, Rattling, Grinding, Squealing, Squeaking, Thumping, Whining, Creaking, Popping, Clicking, Roaring, Loud, High-pitched etc). When engine replacement is necessary, use short block or long block according to following guideline. Do not replace long block assembly if short block assembly or cylinder head assembly will resolve concern. Guideline for Short Engine/Cylinder Head Replacement SERVICE POINTS TO DETERMINE PARTS REUSEABILITY 1. Cylinder Head Check for contact mark between the cylinder head (A) and piston (B). Check for carbon peeling or valve to piston interference. – If OK, flush cylinder head (with valves assembled) with kerosene and blow oil passages with regulated shop air. – If no good, contact MASH for authorization to replace cylinder head assembly and related damaged components.

2004 – 2006 MAZDA3 DESCRIPTION There have been a variety of electrical problems reported where the root cause may be a poorly secured connector, unsecured wire, or bent terminal or pin to the PJB. Many of these problems have occurred after the PJB was removed and reinstalled, as is done for the HVAC diffuser plate or in-cabin filter installation. Examples of these problems include the following: While performing diagnostics, there is no communication with the PJB Door Ajar Light remains on with all of the doors closed Dome light remains on with doors closed or it is inoperative Fog Lights are inoperative A/C not cooling and compressor is inoperative Power door locks are inoperative Turn signals or hazards are inoperative Brake or ABS light remains on with no system problems found Dimmer switch is inoperative Keyless entry is inoperative (with ignition key reminder NOT on with key removed from the ignition). If a vehicle is presenting electrical problems and during diagnosis there are symptoms present that lead you to suspect a poor connection between a wiring harness connector and the PJB, inspect each harness connector and mating terminal on the PJB to determine if they have a proper connection by performing the inspection procedure below. INSPECTION PROCEDURE 1. Record all DTC(s) if any are present. 2. Record all preset radio stations.NOTE: Perform steps 4 and 5 for each of the connectors to the PJB (J-01 – J-06), one at a time, before moving onto step 6.

One of the causes of repeat A/T failures is an internal automatic transmission fluid (ATF) restriction at the inlet side of the oil cooler. This restriction is usually caused by an accumulation of metal particles and debris (from a previous A/T failure) on the internal mesh type baffle of the oil cooler. Power flush- ing will remove the restriction by back flushing the cooler/lines followed by forward flushing. This will in turn ensure full ATF flow for the transmission when it is operating.NOTE: Repeat repairs caused by improper or lack of cooler line flushing will not be covered under warranty, and are subject to review and debit by Mazda Recommended Power Flushing Equipment

the steering effort is hard or heavy with power steering malfunction indicator lamp illumination and DTC C1099 [ELECTRO HYDRAULIC POWER ASSIST STEERING (EHPAS)] stored in memory. This problem is caused by contamination of the system from such things as corrosion getting inside the power steering line, sticking in the power steering pump, and lowering the revolution speed. The system then goes into a fail safe function. Customers having this concern should have their vehicle repaired using the following repair procedure. REPAIR PROCEDURE OUTLINE 1. Verify customer concern. 2. Clean the steering gear box by flushing all fluid lines with 10 quarts of fluid. 3. Remove the electric power steering oil pump assembly (A) and pipe assembly (B). 4. Replace the power steering oil pump unit (shaded part of A) on the pump assembly with oil pump kit. 5. Install the repaired power steering oil pump assembly and new pipe assembly. 6. Fill the pump reservoir with ATF MIII and remove air from the line.
