ENGINE IDENTIFICATION
Engines can be identified by engine model and number. See ENGINE IDENTIFICATION CODE. On Miata,
engine model and number are stamped on flange at upper right rear of cylinder block deck, as viewed from
flywheel. On Protege, engine model and number are stamped on flange at upper left rear of cylinder block deck,
as viewed from flywheel.

REMOVAL & INSTALLATION
FUEL PRESSURE RELEASE & PRIMING
Releasing Pressure (Miata)
Locate and remove fuel pump relay from under left side of dash, near steering column. Start engine and allow to
stall. After engine stalls, attempt to restart engine to ensure no residual pressure exists. Turn ignition off and
reinstall fuel pump relay. When disconnecting fuel hoses, cover connection with shop rag to catch fuel leakage.
To avoid excessive cranking after servicing, prime fuel system before starting engine.
Releasing Pressure (Protege)
NOTE: For repair procedures not covered in this article, see ENGINE OVERHAUL
PROCEDURES article in GENERAL INFORMATION.
ApplicationCode
Miata & Protege (1.8L DOHC)BP
NOTE: Valve clearance is not adjustable. Some Hydraulic Lash Adjuster (HLA) noise
may occur during engine start-up. Noise should disappear after engine reaches
normal operating temperature. If noise persists and oil level is okay, change
engine oil. If oil change does not reduce noise, check with manufacturer for
modified HLA.
NOTE: For reassembly reference, label all electrical connectors, vacuum hoses and
fuel lines before removal. Also place mating marks on engine hood and other
major assemblies before removal.

STEERING SYSTEM - POWER RACK & PINION
1997 STEERING Mazda Power Rack & Pinion
DESCRIPTION
Steering system is a power-assisted rack and pinion. The system consists of a rack and pinion steering gear and
power-assist pump/reservoir. The steering gear and pump/reservoir are connected by flexible lines.
TESTING
HYDRAULIC SYSTEM PRESSURE TEST
Pump Fluid Pressure Test
1. Disconnect pressure line from steering gear and steering pump. Connect pressure gauge/valve between
steering pump and steering gear. See Fig. 1
. Bleed air from system.
2. Completely open valve. Start engine and operate at idle. Turn steering wheel from lock to lock to increase
fluid temperature to 122-140°F (50-60°C). To measure pump fluid pressure, close gauge valve
completely.
3. Increase engine speed to 1000-1500 RPM. Measure oil pump fluid pressure. Ensure pump pressure is
within specification. See HYDRAULIC SYSTEM FLUID PRESSURE SPECIFICATIONS
table. If
pressure is not within specification, replace pump.
CAUTION: DO NOT leave gauge valve closed for more than 15 seconds, or pump may
be damaged.
