Installation Notice

5. Install the drain plug in bottom of radiator.

6. Add the coolant through the coolant reservoir.

7. Warm up the engine until the thermostat begins to open

and check if the coolant level is at “FULL” mark on the
reservoir. Add if necessary.

2. Loosen the drain plug in bottom of radiator and drain the

coolant.

1. Release the pressure from coolant reservoir by loosening

one notch of coolant reservoir cap, and then remove the

Notice

Scalding hot coolant and steam could be blown out
under pressure, which could cause serious injury.
Never remove the coolant reservoir cap when the
before the temperature goes down below 90°C.

Notice

Collect the drained coolant with a proper container.

OVERVIEW

Glow plug is installed on the cylinder head (combustion chamber) in the D27DT preheating control unit system. Cold
starting performance has improved and exhaust gas during cold starting has reduced.

ECU receives coolant temperature and engine speed to control; after monitoring the engine preheating/after heating and
glow plug diagnosis function, the fault contents will be delivered to ECU.

• Engine preheating/after heating functions

• Preheating relay activation by ECU controls

- Senses engine temperature and controls the preheating/after heating time

- Glow indicator

• K-LINE for information exchanges between preheating unit and ECU

- Transmits preheating unit self-diagnosis results to ECU

- Transmits glow plug diagnosis results and operating status to ECU
