When the engine is warm (NOT HOT) open the radiator drain plug or remove bottom hose.
Ensure your car is parked on level ground with the hand brake applied
Set heater control to 'hot'
Replace drain plug / radiator hose
Remove radiator cap. Use a water pressure hose to flush out old coolant
Put recommended quantity of HP Koolgard into radiator. Top up with water and replace cap
Run engine for 5 minutes. Check water level and top up if necessary
Complete flushing and renewal of your engine coolant should occur at least every two years. Once every year engine coolant changes are desirable, if concentration is not well maintained. Most car engines have a coolant system which requires a glycol based coolant mixed with water. The glycol base acts as an anti - freeze and maintains the physical characteristics of coolant, which continuously protects your engine parts from corrosion and damage. The concentration of HP Koolgard in water should be minimum 30%, or as per vehicle manufacturer's recommendation, so as to attain complete protection.
Please check: Keep a close watch on radiator hose and fittings. A damaged radiator
hose or a loose fitting may result in leakage and overheating. Check the pressure of the radiator cap. Keep observing the change in colour of water being drained from the radiator; it can give you an indication of your engine's health.
