H. COOLANT REPLACEMENT

1. Allow the engine to cool up to ambient tempera-

ture if it is hot.

2. Keep a suitable container below the radiator

drain plug to collect the coolant that will drain

3. Open the coolant tank cap

(1).

4. Loosen the Drain plug till the coolant starts to

drain from the drain tube and drain the coolant.

NOTE

The complete cooling system including oil cooler will

be drained.

5. Pour fresh water through the coolant tank to en-

sure all used coolant is flushed out of the system

6. Using dry compressed air (up to 1 bar) at the

coolant tank, flush out the coolant completely.

7. Drain the Coolant tank and refit the hoses.

COOLANT RE-FILLING PROCEDURE

1. Reconnect all the hoses and secure the hose

clamps properly.

2. Refit the radiator drain plug.

3. Use a funnel for coolant filling.

4. Hold the funnel over coolant tank. Refill the cool-

ant in the system through funnel. The filling rate

should be 1.0 liter / min approx.

5. When coolant level comes up to coolant tank max

level, wait and allow air bubbles to escape from

the system for 5 to 10 min. Top up coolant once

the level drops.

6. Start the engine and run in stationary condition at

2000 to 2200 rpm till thermostat opens and con-

tinue to run for 5 mins. (The radiator fans coming

on is indication of opening the thermostat)

7. Wait after stopping the engine to allow engine to

come at atmospheric temp. Top up coolant in fill-

er neck after stopping the engine.

8. Repeat the step 6 and 7 twice.

9. The coolant refilling is complete now.

10.Ensure that there are no leakages in the com-

plete cooling system.

NOTE

It is recommended to refill the coolant in the engine

through the vacuum evacuation system, if available.
