COOLANT DRAIN AND FILL UP Draning & Filling up Procedure 1. Loosen the cap a little and release pressure and remove the cap. NoticeFor the risk of scalding, the cap must not be opened unless the coolant temperature is below 90 o
C.
2. Loosen the radiator lower drain cock and drain the coolant.
Notice Collect coolant by using a proper container.
3. Drain the coolant from the crankcase by inserting a hose(dia. 14mm) onto the drain bolt on the side of crankcase (exhaust manifold) and by loosening the plug. Notice
Just loosen the drain plug to drain the coolant and do not remove the plug completely.
Collect coolant by using proper container.
4. After complete draining of the coolant, remove the hose connector to drain plug and reinstall the drain plug. Installation Notice
5. Tighten the radiator lower drain cock.
