Tip: whenever you take your car to the dealer for servicing, ask to top up the coolant. If there is a leak, it must be repaired before a lack of coolant caused the engine to overheat. If the coolant level is very low or there is a smell of coolant or signs of leaks under the hood, have the cooling system pressure tested for possible leaks. Check your owner's manual for safety precautions and the proper way to do it.
If the coolant level is just a bit lower, as in the photo, it needs to be topped up, using the right type of coolant. Some amount of coolant normally evaporates as you drive. Low coolant level can also cause the heater to blow cold air from the vents. The level should be between the "Low" and "Full" or "Min" and "Max" marks.Ĭaution, don't open the radiator cap or the pressurized overflow tank cap when the engine is hot! The cooling system is under pressure when hot. Visually check the engine coolant (antifreeze) level in the overflow tank. The cooling system keeps the engine temperature in check, but to work properly it needs to have enough coolant. Many expensive engine repairs, such as blown head gaskets are caused by overheating.

There are typically marks on the reservoirs for you to use as a guide. Check the fluid levels of the brake and clutch cylinders (if applicable).A tread depth less than a match-head is unsafe and illegal. Check for abnormal tyre wear which may indicate incorrect pressure or a wheel alignment problem.If you have to use your space saver spare tyre, it should not be driven at speeds above 80 kph or for distances exceeding 100km.Usually, space saver spare tyres should be inflated to 420 kps / 60 PSI. Check tyre pressure regularly including the spare.In this situation, consult a battery specialist or automotive technician. A battery labelled "low maintenance" or "maintenance free" could still be low on fluid.Check the electrolyte level and top up with water if required.Ensure the terminals are clean and securely tightened.If the belt appears loose, have an automotive technician make the necessary adjustments especially in newer cars. Check for fraying, cracks or other signs of deterioration.When driving, particularly on long journeys, continuously check your oil and water indicators, and warning lights.Vehicles with air conditioning occasionally drip water from the condenser drain pipe, so any apparent leakage may not necessarily be from the engine cooling system. Look for signs of oil or coolant leakage on the driveway after your vehicle has been parked.If your oil is darker than usual and you're unsure of the mileage or when your last service was, the oil should be replaced. Engine oil tends to get darker in colour as it ages. Check the engine oil level using the dipstick when the engine is cold - perform this check twice.Check radiator and heater hoses for signs of deterioration, leakage, softening and loose clamps.Leaks are indicated by the presence of water or water staining. Check the radiator core and tanks for leaks.Check the seal on the radiator cap and for evidence of sludge build-up on the underneath of the cap and in the neck of the radiator.Coolant level should be high when your vehicle is hot and low when your vehicle is cold. Check the operation of the expansion tank (if fitted).Check the radiator coolant level when your vehicle is cold.Check your manufacturer's recommendation. Your vehicle should be serviced at regular intervals- usually every 10,000km or every 12 months (whichever occurs first).Generally, ensure increased fuel or oil consumption, hard starting, rough running or any unusual noises experienced while driving are promptly inspected by an automotive technician.
