Nissan Terrano model r20 series 2004. Manual — part 26
1. Warm up engine.
2. Turn ignition switch OFF.
3. Using CONSULT-II, make sure no error codes are indicated for
self-diagnosis items. Refer to EC section, “Fuel Pressure
Release”.
I
Do not disconnect CONSULT-II until the end of this operation;
it will be used to check engine rpm and for error detection at
the end of this operation.
4. Disconnect the negative battery terminal.
5. Remove the following parts.
I
Intercooler
I
Throttle body
I
Rocker cover
6. To prevent fuel from being injected during inspection, remove
fuel injection pump fuse [ENG CONT A/T (15A)] from fuse box
on the right side of engine compartment.
7. Remove glow plugs from all the cylinders.
I
Before removal, clean the surrounding area to prevent
entry of any foreign materials into the engine.
I
Carefully remove glow plugs to prevent any damage or
breakage.
I
Handle with care to avoid applying any shock to glow
plugs.
8. Install adapter (SST) to installation holes of glow plugs and
connect compression gauge for diesel engine.

9. Connect battery negative terminal.
10. Set the ignition switch to “START” and crank. When gauge
pointer stabilizes, read compression pressure and engine rpm.
Repeat the above steps for each cylinder.
I
Always use a fully-charged battery to obtain specified
engine speed.

I
When engine rpm is out of the specified range, check the spe-
cific gravity of battery liquid. Measure again under corrected
conditions.
I
If engine rpm exceeds the limit, check valve clearance and
combustion chamber components (valves, valve seats, cylinder
head gaskets, piston rings, pistons, cylinder bores, cylinder
block upper and lower surfaces) and measure again.
11. Complete this operation as follows:
a. Turn the ignition switch to “OFF”.
b. Disconnect battery negative terminal.
c. Replace glow plug oil seals and install glow plugs.
d. Install fuel injection pump fuse [ENG CONT A/T (15A)].
e. Connect battery negative terminal.
f.
Using CONSULT-II make sure no error code is indicated for
items of self-diagnosis. Refer to EC section, “Trouble Diagno-
sis — Index”.
