    HOW TO MAINTAIN THE COOLING SYSTEM OF VOLVO GENERATOR ENGINE

 - Different types of coolant must not be mixed with each other.

- Risk of reduced cooling function and performance by clogging and isolation..

- Follow the mixing recommendation on the product.

- The coolant should be mixed with distilled, deionized water. For Volvo Penta specified water requirements

  # NOTICE:

    Always use “Ready Mixed” coolant if water quality cannot be determined or if it does not fulfill ASTM D4985.

    Never mix more than 60% concentrated coolant with water. 

1) Coolant Level, Checking and Topping up.

    # NOTICE:

      - Do not open the coolant filler cap when the engine is hot, except in emergencies as this could cause serious personal injury. Steam or hot fluid could spray out

      - Only use coolant recommended by Volvo Penta. Fill up with the same type of coolant that is in the system. Different types of coolant must not be mixed with each other

      - Filling of coolant must be performed with the engine stopped. Fill up slowly, to allow the air to flow out. Check the coolant level daily before start.

    # Carry out:

      - TWD16:

        1- Open the filler caps (1).

        2- Check that the coolant reaches the MAX mark on the sight glass (2). Top up with coolant as required

        3- Close the filler caps.

        -  TAD16:

        1- Open only the filler cap (1). Do not open the pressure cap (2).

        2- Check that the coolant level is between the MIN and MAX marks on the expansion tank (1). Top up with coolant as required

        3- Close the filler cap.

  2) Filling a completely empty system.

    - Mix the correct amount of coolant in advance, to ensure that the cooling system is completely filled. Refer to Technical Data, page 91 for the correct coolant volume.

    - Do not start the engine until the cooling system is completely filled and vented.

    - If a heating unit is connected to the engine cooling system, the heating control valve should be opened and the installation vented during filling.

    - Carry out topping up in the cooling system:

      1- Kiểmtraxemtấtcả drain points đãđượcđónglại.

      2- TWD16:

           Open the caps to both the expansion tank (1) and the radiator (2). Fill the expansion tank so that the coolant reaches the MAX mark on the sight glass. Close the filler caps.

          TAD16

          Open only the filler cap (1). Fill the expansion tank so that the coolant level is between the MIN and MAX marks. Close the filler cap.

        3- Bleed the system at the bleeding nipple (3).

      4- Start the engine when the coolant system completely filled and vented. Open any bleeding nipples a short while after starting, to allow trapped air to escape.

      5- Start the engine after approx. one hour and check the coolant level. Top up with coolant as required.

3) Coolant, Draining.

    - On engines which are to be put in storage, the engine cooling system should not be drained. the coolant contains corrosion inhibiting additives.

      1- Stop the engine before draining.

      2- TWD16

          Open both the pressure caps on the expansion tank (1) and the filler cap to the radiator (2).

          TAD16

          Open the filler cap (1). Do not remove the pressure cap (2).

      3- Open all drain points. Drain the coolant from the radiator and engine block, using the drain hose. The drain nipples are situated under the radiator on the right side of the engine block.

      4 - Check that all coolant drains out. Deposits may be found inside the drain plug/tap, and need to be cleared away. There is otherwise a risk that the coolant could remain and cause frost damage. Check whether the installation has any further taps or plugs at the lowest points of the cooling water pipes.

      5- Close any taps and check that the spring-loaded covers on the nipples close completely. Install the rubber plugs and the filler cap(s).

4) Charge Air Cooler, External Cleaning.

    - Do not use a high pressure power washer.

    - Remove guards as necessary, to access the radiator.

    - Clean with water and a mild detergent. Use a soft brush.

    - Be careful not to damage the radiator vanes. Reinstall removed parts.

5) Cooling System, Cleaning.

    1- Empty the cooling system. Refer to Coolant, Draining, page 75.

    2- Put a hose into the expansion tank filling hole and flush with clean water, as specified by Volvo Penta– refer to section Water quality in Technical Data, page 91 until the water draining out is completely clear.

    3- If there should still be some contamination left after flushing for a long time, cleaning can be done with coolant. Otherwise, continue as in item 8 below.

    4- Fill the cooling system with 15-20 % mixture of concentrated coolant. Use only Volvo Penta recommended concentrated coolant mixed with clean water.

    5- Drain the coolant after 1-2 days of operation. Remove the filler cap and possibly the lower radiator hose to increase the speed of emptying. To prevent suspended material from settling back in the system emptying should be done rapidly, within the space of 10 minutes, when the engine has not been standing still for a long time.

    6- Flush the system immediately and thoroughly with clean hot water to prevent dirt from settling in the inner areas. Flush until the water that runs out is completely clean. Make sure that any heater controls are set to full heating during emptying.

    7- If contamination should still be left after a long period of flushing, cleanout using Volvo Penta radiator cleaner, followed by finishing-off with Volvo Penta neutralizer. Carefully follow the instructions on the package. Otherwise, continue as in item 8 below.

    8- When the cooling system is completely free from contamination, close the drain taps and plugs

    9- Fill up with Volvo Penta recommended coolant, following the instructions in the chapters entitled Maintenance, page 72 and Coolant Level, Checking and Topping Up, page 73.

Solutions to typical fault codes of diesel generator sets

This article is mainly about dealing with typical fault codes of diesel generator set, hope it is helpful to you.

1.Fault code 131,132

131: No. 1 accelerator pedal or lever position sensor circuit, voltage above normal value or short circuit to high voltage source.

132: No. 1 accelerator pedal or lever position sensor circuit, voltage under normal value or short circuit to low voltage source.

(1)Fault phenomenon

The voltage on accelerator pedal position sensor 1 circuit is high(fault code 131) or low (fault code 132).

(2)Circuit description

The throttle position sensor is a Hall effect sensor connected to the accelerator pedal, the signal voltage from the throttle position sensor to the ECM will change when the accelerator pedal is depressed or released. When the accelerator pedal is at 0, the ECM will receive a low voltage signal; When the accelerator pedal is at 100%, the ECM will receive a high voltage signal. The accelerator pedal position circuit includes 5V power circuit, return circuit and signal circuit. The accelerator pedal has two position sensors which are used to measure the throttle position. Both position sensors receive 5V power from the ECM and the corresponding signal voltage from the ECM according to the accelerator pedal position. The No. 1 throttle position signal voltage is twice of the No. 2 throttle position signal voltage. This fault code is set when the ECM senses a signal voltage that is below the normal operating range of the sensor.

(3)Component location

The accelerator pedal or lever position sensor is located on the accelerator pedal or lever.

(4)Reason

Accelerator pedal or lever position signal circuit short circuit to battery or + 5V source;

Broken circuit in accelerator pedal circuit in harness or connector;

Accelerator power supply short circuit to battery;

Faulty accelerator pedal or lever position sensor;

Wrong installation of accelerator pedal during maintenance.

(5)Solution ways

Check whether the wiring of accelerator pedal is correct;

Check whether the accelerator pedal position sensor and connector pins is damage or looseness;

Check whether the accelerator pedal position sensor voltage and return voltage are about 5V;

Check if the ECM and 0EM harness connector pins are damage or looseness;

Check if the ECM and 0EM harness circuit is open or short.

2.Fault code 331, 332

331:The current in No.2 cylinder injector solenoid driver is below normal value or open.

332: The current in No.4 cylinder injector solenoid driver is below normal value or open.

(1)Fault phenomenon

The engine may misfire or run rough; the engine is weak under heavy load.

(2)Circuit description

When the injector solenoids control the amount of fuel injected, the electronic control module (ECM) supplies power to the solenoids by turning off the high and low switches. There are two high-end switches and six low-end switches in the ECM.

The injectors of cylinders 1, 2 and 3 (front) share a single high-end switch inside the ECM, which connects the injector circuit to the high-pressure power supply. Similarly, four, five and six cylinders (back row) share a single high-end switch inside the ECM. Each injector circuit in the ECM has a dedicated low-end switch, which forms a complete circuit to the ground.

(3)Component location

The engine harness connects the ECM to three through connectors for the injector circuits that are located in the rocker arm housing. The internal injector harness is located under the valve cover and connects the injector to the engine harness at the through connector. Each through connector supplies power to both injectors and provides a return circuit.

(4)Reason

331 fault alarm caused by abnormal operation of cylinder 1, 2 and 3 injectors;

332 fault alarm caused by abnormal operation of cylinder 4, 5 and6 injectors;

Virtual connection of engine injector connecting harness or injector connecting wire;

The injector solenoid is damaged (high or low resistance);

ECM internal damage.

(5)Solution ways

Check the fuel injector harness for virtual connection or short circuit;

Check the pins in the injector connection harness for a short circuit caused by oil contamination.

3.Fault code 428

428: Water in fuel indicator sensor circuit, voltage above normal value or short to high source.

(1)Fault phenomenon

Engine water in fuel fault alarm.  

(2)Circuit description

The water in fuel (WIF) sensor is attached to the fuel filter and the electronic control module provides a 5V DC reference signal to the water in fuel sensor. After the water collected in the fuel filter covers the sensor probe, the water in fuel sensor makes the 5V reference voltage grounded, indicating that the water in fuel filter is high.

(3)Component location

Water in fuel sensor is generally provided by 0EM and synthesized on vehicle fuel prefilter.

(4)Failure reason

Alarm caused by too much water in prefilter;

Alarm caused by disconnection of harness connector of connecting sensor;

Alarm caused by reverse connection of connecting harness;

Alarm caused by wrong sensor model

Broken in harness, connector or sensor return or signal circuit;

The signal wire is shorted to the sensor power supply.

(5)Solution ways

Check whether the vehicle prefilter has accumulated water;

Check whether the sensor matches;

Check whether the sensor wiring is correct and whether the connector contacts;

Generally, the alarm "428" will be given when two wires are short circuited.
