radiator fan switch HONDA CR-V 1999 RD1-RD3 / 1.G Owner's Manual

Stall Speed
Test
CAUTION:
. To prevent transmission damage, do not te3t stall speed for mors than 10 s€€onds at a time'
. Do not shift the lever while raising th€ engine spsed.
. Be sure to remove tho pressuro gauge bofore testing stall speed,
1. Before testing, check the transmission fluid level, s€e page 14-160.
2. Engage the parking brake and block all four wheels
3. Connect the tachometer, and start the engane.
4. Make sure the Ay'C switch is OFF
5. After the engine haswarmed upto normal operating temperature (the radiator fan comes on),shiftinto@ position.
6. Fully press the brake pedal and accelerator for 6 to 8 seconds, and note engine speed '
j. A|ow 2 minutes for cooling, then repeat the test in E, E ('97 - 98). E {'99 - 00}, and E positions. Stall speed should
be the same in E, E, E, tr. and E positions
Stall Speed rpm:
Specitication: 2,550 rpm
S€rvice Limit: ?,400 - 2.700 rpm
TROUBLEPROBAELE CAUSE
Stall rpm high in El, E, E, E and E
positions
ATF pump output is low
Clogged ATF strainer
Pressure regulator valve stuck closed
Slipping clutch
Stall rpm high in E positionSlippage of 1st clutch, 1st-hold clutch, or 1st gear one-way clutch
Stall rpm high in E positionSlippage of 2nd clutch
stall rpm high in E! or E positionSlippage of 1st clutch or 1st gear one-way clutch
Stall rpm high in E positionSlippage of 4th clutch
Stall rpm low in [dd, E. E, E, ana E
positions
. Engine output low
. Torque converter one-way clutch slipping

Instail the transmission ground cable terminal on
the transmission hanger, and install the radiator
hose clamp on the transmission hanger,
Connect the starter cables to the starter, and install
the harness clamD on the clamD bracket. Make sure
the crimped side of the starter cable ring terminal is
facing out.
STARTEBCABLE
STARTER CAAtf,
Install the air cleaner housing assembly and the
intake air duct.
Refill the transmission with ATF (see page 14-161).
Connect the battery positive terminal and negative
terminal.
Set the parking brake, Start the engine, and shift the
transmission through all gears three times.
Check the shift cable adjustment (see page 14-271]-.
Check the tront wheel alignment and adjust it if
needed (see section 18).
Let the engine reach normal operating temperature
(the radiator fan comes on) with the transmission in
E or N position, then turn it off and check the ATF
level {see page 14-160).
Perform a road test (see page 14-157 and 14-158).
