DIAGNOSTIC INFORMATION AND PROCEDURE
COMPRESSION PRESSURE CHECK
Tools Required
09915–64510 Compression Pressure Gauge
Check the compression pressure in the following proce-
dures:
1. Warm up the engine to the normal operating tempera-
ture (Cooling temperature : 80–90C (176–194F)).
2. Stop the engine and then remove the high tension
cable and the spark plug.
3. Disconnect the distributor optical sensor connector.
4. Install the compression pressure gauge 09915–64510
(a) in the hole of spark plug.
D12B301A
5. Disengage the clutch in Neutral (to lighten starting
load on engine upon cranking), and depress the ac-
celerator all the way to make the throttle fully open.
6. Crank the engine with the starting motor, and read the
highest pressure on the compression pressure gauge.
The difference of measured value between cylinders
is 98.06kPa (14.22 psi) and less.
On checking, make the connection perfectly airtight
between the hole of spark plug and compression pres-
sure gauge.

7. After checking, remove the gauge and install the re-
moved parts.
OIL PRESSURE CHECK
Tools Required
09915–77310 Oil Pressure Gauge
Prior to check oil pressure, check the followings:
Check oil level and add if required.
Replace the discolored, deteriorated or diluted oil.
Check any oil leakage and repair the defective parts.
Check the compression pressure in the following proce-
dures:
1. Remove the oil pressure switch (b) from the cylinder
block.
2. Install the oil pressure gauge 09915–77310 (c) to the
mounting place of the oil pressure switch.
D12B302A
3. Start the engine and warm up to the normal operating
temperature.
4. Raise the engine speed up to 2,000rpm and then
read oil pressure.

5. After checking, wrap the threads of oil pressure
switch with a seal tape and tighten it to the specified
torque 12–16 N
m (106–144 lb-in).
6. Start the engine and check oil pressure switch for oil
leakage.

CAUTION: Disconnect the negative battery cable before removing or installing any electrical unit or when a
tool or equipment could easily come in contact with exposed electrical terminals. Disconnecting this cable
will help prevent personal injury and damage to the vehicle. The ignition must also be in B unless otherwise
noted.

1D–4 ENGINE COOLING
DAEWOO M-150 BL2
The main fan size is 320 mm (12.6 in.) in diameter with
seven blades(k) to aid the air flow through the radiator
and the condenser. An electric motor(l) attached to the
radiator support drives the fan.
A/C OFF or Non-A/C Model
The cooling fan is actuated by the electronic control
module (ECM) using a low speed cooling fan relay
and a high speed cooling fan relay. On A/C equipped
vehicles, a series/parallel cooling fan relay is also
used.
The ECM will turn the cooling fan on at low speed
when the coolant temperature reaches 93
C (199
F)
and high speed at 100
C (212
F).
The ECM will change the cooling fan from high speed
to low speed at 97
C (207
F) and turn the cooling
fans off at 90
C (194
F).
A/C ON
The ECM will only turn the cooling fan on at high
speed when the A/C system is on regardless of any
condition.
ENGINE COOLANT TEMPERATURE
SENSOR
The engine coolant temperature (ECT) sensor (n) uses
a thermistor to control the signal voltage to the engine
control module (ECM).
D102D004
COOLANT TEMPERATURE SENSOR
The coolant temperature sensor(m) controls the instru-
ment panel temperature indicator. The coolant tempera-
ture sensor is located on the distributor case with the
ECT sensor on an SOHC engine.
