TECHNICAL INFORMATION TIP
ROTARY ROUGH IDLE
YEAR(S): 1982-85
MANUFACTURER: Mazda
MODELS: RX-7
DATE OF ISSUE: June 1993
ISSUE: BAD SHUTTER VALVE CAUSES ROUGH IDLE/NO IDLE
A bad shutter valve may cause a rough or no idle on 1982-85
Mazda RX-7 models. To test the shutter valve, remove the hose from the
valve (it's located below the carburetor) and check for vacuum. If
there is vacuum at idle, the shutter valve is bad and should be
replaced.
Another thing to check that may be causing your idle problems is
the vacuum hose that leads from the carburetor to the AA valve. This
large hose may be burned or split at the bend in the hose near the
intake manifold and can introduce a large vacuum leak if it's leaking.

ENGINE COOLANT
Model: ALL MODELS
Bulletin No.: 008/87
Date: 7/16/87
Category: 3
DESCRIPTION
The proper level for the coolant is between the "FULL" and "LOW" marks
on the coolant reservoir. If the level is below the "LOW" mark when
the engine is cool, add enough 50/50 mixture of water and ethylene
glycol anti-freeze mix to bring the level up to or near the "FULL"
mark. Do not overfill.
In addition to freezing protection, ethylene glycol provides corrosion
protection for aluminum engine parts.

CAUTION WHEN ADDING COOLANT
1. If water only is added, the mixture ratio of coolant will be
reduced, which may result in the following:
* Rust or corrosion in the engine.
* Water leakage or overheating caused by rust or corrosion in the
radiator.
* Water leakage due to corrosion of the water pump at the seal.
2. If the reservoir is overfilled, a rise in coolant temperature will
cause expansion of the coolant volume, which will allow some
coolant to overflow. The customer may misunderstand this overflow
to be a mechanical problem.
CAUTION WHEN REPLACING COOLANT
After replacement, set the heater control lever to the "HOT" position
and warm up the engine to the normal operating temperature (Thermostat

fully open). Check that there are no coolant leaks.
Add additional coolant as needed so that the radiator is full and the
coolant level is at the "FULL" mark on the coolant reservoir.
NOTE: If you encounter a reservoir bottle that is empty, it is likely
that the level of coolant inside the radiator is also low. In
such a case always.
1. Wait until the engine is cool and then remove the radiator cap. Add
coolant as needed to bring the level inside the radiator up to
full.
2. Pressure check the radiator and radiator. Also perform general
check of coolant system.
