7) When refrigerant container (1) is emptied, use the
following procedure to replace it with a new
refrigerant container.
a) Close low pressure valve.
b) Replace empty container with a refrigerant
container which has been charged with
refrigerant. When using refrigerant container tap
valve (2), use the following procedure for
replacement.
i)
Retract needle (3) and remove refrigerant
container tap valve by loosening its plate nut
(4).
ii) Install the refrigerant container tap valve to a
new refrigerant container.
c) Purge any air existing in center charging hose.
When using refrigerant container tap valve, use
the following procedure to purge air.
i)
Once fully tighten refrigerant container tap
valve (1), and then loosen (open) plate nut
(2) slightly.
ii) Open low pressure side valve (3) of manifold
gauge set (4) a little.
iii) As soon as refrigerant comes out with a
"hiss" through a clearance between
refrigerant container and tap valve, tighten
plate nut as well as low pressure side valve.
iv) Turn handle of tap valve clockwise so that its
needle is screwed into the new container to
make a hole for refrigerant flow.
Air Conditioning System: Manual Type 7B-21
8) After the system has been charged with specified
amount of refrigerant or when low pressure gauge
(1) and high pressure gauge (2) have indicated the
following specified value, close low pressure side
valve (3) on manifold gauge set (4).
Specified amount of refrigerant
430 ± 20 g (15.2 ± 0.7 oz))
Low side and high side pressure example
Gauges should read as follows when ambient
temperature is 30 °C (86 °F).

Removal of Manifold Gauge Set
WARNING
!
High pressure side is under high pressure.
Therefore, be careful not to get injured
especially on your eyes and skin.
For the A/C system charged with the specified amount of
refrigerant, remove manifold gauge set as follows:
1) Close low pressure side valve of manifold gauge set.
(The high pressure side valve is closed continuously
during the process of charging.)
2) Close refrigerant container valve.
3) Stop engine.
4) Using shop rag, remove charging hoses from service
valves. This operation must be performed quickly.
5) Put caps on service valves.

Adjust throttle motor

The idle speed on a Suzuki SX4 should be controlled by the Idle Air Control Valve (IACV) rather than adjusting the idle screw on the throttle body, as the screw is factory set. Before using compressed air in the idle-air-bypass passages, the IACV should be removed to prevent damage to its delicate mechanism. If there is an issue with idle speed, checking the IACV function and referring to the SX4 service manual is recommended.

Possible issues with the heater in a Suzuki SX4 if the blower is working but the heater is not include:

1. Incorrect Temperature Output
- Temperature control cable broken or bent (non-A/C and manual A/C) → Check the temperature control cable.
- Temperature selector faulty (non-A/C and manual A/C) → Check the temperature selector.
- Incorrect installation of the temperature control cable (non-A/C and manual A/C) → Check and adjust the position as necessary.
- Temperature control door assembly broken → Repair the temperature control door assembly.
- Air ducts clogged → Repair air ducts.
- Heater core leaked or clogged → Replace the heater core.
- Heater hoses leaked or clogged → Replace heater hoses.
- Thermostat faulty → Check the thermostat.
- Temperature control actuator faulty (auto A/C) → Check the temperature control actuator.
- HVAC control module faulty (auto A/C) → Check the HVAC control module.
- Wiring or grounding faulty (auto A/C) → Repair as necessary.

2. Other Possible Causes
- Air flow control cable broken or bent → Check the air flow control cable.

Checking and addressing these components should help identify and resolve the heater issue.

increasing revs when changing gears

1 comments:
Mr. Anderson

The Suzuki SX4 may have increasing revs when changing gears due to its drive-by-wire system and the difference in final drive ratios between the manual (4.41) and automatic (2.81) transmissions. This difference causes high cruising RPMs in the manual version and sluggishness in the automatic. Additionally, if the revs climb while going uphill, it may be due to the transmission downshifting or kicking out of overdrive. Other possible causes include low transmission fluid, abuse, or a faulty transmission design.
