relieve any pressure, before
removing cap completely.
When the engine overheats and hot coolant overflows
through the overflow pipe and cannot be stopped, stop
the engine immediately and make the following checks
to determine the cause of trouble:

1. Check to see if there is any coolant leak;
2. Check to see if there is any obstacle around the
cooling air inlet or outlet;

radiator fins and tube;
4. Check to see if the fan belt is too loose;
5. Check to see if radiator water pipe is clogged; and
6. Check to see if anti-freeze is mixed into coolant in
warm seasons.
