PREVENTIVE MAINTENANCE
Topping Up
With the engine cold, top up with premixed ELC30 coolant. Add coolant
through the filler cap on top of the surge tank atop the radiator. For correct
level, see illustration below.

If frequent topping up becomes necessary and there are no visible signs
of coolant leaks when the engine is cold, check for leaks with the engine
in operation at normal operating temperature. The system may be leaking
when pressurised. Never use 100% antifreeze to top up coolant.
UNDER NO CIRCUMSTANCES REMOVE THE PRESSURE CAP
Do not add stop leak to the cooling system. Stop leak collects around
turbulators in the radiator, interfering with proper cooling.
Standard System Refill
1. Verify that the radiator and engine block drains are closed.
2. Move the heater control to maximum heat position.
3.
Remove the surge tank filler cap.
4. Fill the system through the surge tank with premixed coolant in an
uninterrupted flow until the radiator is full.
5. Start the engine.
6. Idle at low rpm.
7.
Complete the filling as quickly as possible.
