Batteries rarely last longer than five years so replacing one near the end of its life can save a lot of time and inconvenience at the side of the road.

Avoid running electrical systems any longer than necessary – turn the heater fan down and switch the heated rear window off once windows are clear. Turn off nonessential electrical loads like lights, rear screen heater and wipers before trying to start the engine and use the starter in short five-second bursts if the engine doesn’t start quickly, leaving 30 seconds between attempts to allow the battery to recover. ANTIFREEZE: A continuous squealing noise as soon as the engine is started is a sign the water pump is frozen. The cylinder block could be frozen too. Stop the engine immediately and allow it to thaw out. This may take several days unless the car can be moved to a heated garage.

If the car begins to overheat a few miles from home it’s likely that the radiator has frozen, preventing coolant from circulating. Stop straight away to avoid serious damage and allow the radiator to thaw.

Most modern cars use long-life antifreeze, so it’s important to use the right type and avoid mixing different types. Check the handbook or ask a dealer for advice. Glycol-based antifreeze should be changed at least every two years.
