Checking Preweld Measurements And Watching
Align to the standard reference dimensions, based upon the body dimensions illustration, so that new parts are installed in the correct position.
Welding Notes
For the number of weld points, welding should be performed in accordance with the following reference standards.
Spot Welding Notes
The shape of the spot welder tip is D=(2?t)+3. If the upper panel thickness is different from that of the under panel, adjust to the thinner one.
Because the weld strength is affected by the shape of the spot welder tip, the optimum condition of the tip should always be maintained.
Spot welds should be made at points other than the originally welded points.
Before spot welding, make a trial weld using the same material as the body panel to check the weld strength.
Checking Weld Strength
Installation locations of the engine, chassis, and seat belts are designated as important safety locations for weld strength. Check weld strength by driving a chisel between the panels at every fourth or fifth weld spot, and every tenth regular weld location.
Drive the chisel between the panels according to the number of panels as shown below.
To determine weld strength, drive the chisel between the panel and check whether the panels come apart. If the panels come apart, make another weld near the original weld.
Restore the shape of the checked area.
Rear Seat Removal/Installation
CAUTION:
When removing or putting in the rear seat, contact with the surrounding areas
of the vehicle could cause scratches and damage. When removing or putting in
the rear seat, always use two or more persons to perform the work and be careful
not to scratch or damage the rear seat ...
Break-In Period
No special break-in is necessary, but a few precautions in the first 1,000 km
(600 miles) may add to the performance, economy, and life of your Mazda.
• Do not race the engine.
• Do not maintain one constant speed,
either slow or fast, for a long period of time.
• Do not drive constantl ...
Intake Air Temperature (Iat) Sensor
IAT Sensor No.1
Purpose/Function
Detects the IAT before it passes through the throttle body as basic information
for mainly determining the fuel injection amount.
Detects the IAT before it passes through the throttle body and inputs it
to the PCM as an IAT signal.
