To keep your car looking good and performing well, OzFreeOnline offers you suggestions on checking the Coolant (Antifreeze) level as well as the engine oil level.

COOLANT (ANTIFREEZE) LEVEL

Never open the radiator of a car that has just been running. The cooling system of a car is under high pressure with fluid that is usually hotter than boiling water. Look for the cooling system reserve tank, somewhere near the radiator. It is usually translucent white so you can see the fluid level without opening it. (Do not confuse it with the windshield washer tank). The reserve tank will have two marks on the side of it. ‘FULL HOT’ and ‘FULL COLD.’ If the level frequently goes below ‘full cold’ after adding fluid, you probably have a leak, which should be checked as soon as possible. Today's engines are much more susceptible to damage from overheating, so do not neglect this important system.

ENGINE OIL LEVEL

An engine cannot run without oil; oil is what prevents serious engine damage or total destruction! To check the oil level, make sure that the engine is turned off, then find the engine oil dipstick and remove it. With a paper towel or rag, wipe off the end of the stick and notice the markings on it. You will usually see a mark for ‘Full’ and another mark for ‘Add.’

Check your owner’s manual to be sure. Push the stick back into the tube until it sets, then immediately pull it out to see the oil level. You should not add oil unless the level is below the ‘Add’ mark and NEVER add oil to bring the level above the ‘Full’ mark. Your main concern with this check is that oil consumption is not rapidly increasing. If it is, take your car to a repair shop as soon as possible and have it checked out. It is acceptable for the oil to be dark as long as you change it at the recommended intervals. However, it should never be foamy and should never have a strong petrol smell. If either of these conditions exists, have it checked out soon.
