Easy mistake when starting up your car in cold could cost you over £1k in damage
AN easy mistake when starting up your car in cold weather could cost you over £1,000.
As temperatures drop below zero drivers are being warned that cold starts can wreck the engine.
Now a motor expert has warned drivers that a broken piston could cost £1,000 to repair.
The expert warned drivers to warm their cars slowly to avoid damaging the piston and other components.
Speaking on his YouTube channel, TorqueCars, he explained: “You want everything to be correctly bedded into place.
“As the piston is going up and down and handling the explosion going on inside the cylinders, you really want that piston and the piston rings to be as close to the cylinder wall as possible
otherwise you're just going to lose all of that energy.
“Plus if it’s not fitting precisely it’s going to rattle around and that's a condition we will refer to as piston slap.
“Now all engines experience piston slap but it's usually to a very small degree unless the wear and tear has happened.”
He advised drivers to gently warm the car and not to rely solely on the water temperature reading on the dashboard.
He said : "Drive it gently until the engine oil is up to temperature. Specifically the engine oil because the water temperature is not an indicator of the engine being up to temperature
"The actual operating temperature of the engine usually happens a little while after the engine's water has got up to temperature.
"That's just the nature of the water cooling system and the way it works so it's a good idea to get an oil temperature sensor fitted to your car just to be extra sure."
Expert mechanic Scotty Kilmer recently warned drivers about the risk posed by cold weather.
Scotty said: "Don’t run your tank low as there’s a lot of water vapour in the air.
"If it’s cold then the water vapour can freeze and you can get stuck, so I always make a point of filling the car up more often in the winter."
Secondly, the motors whizz addressed a common winter gripe for UK drivers. He explained: "You might as well get your battery tested.
"Batteries cost a tonne of money if you’re stuck in the middle of nowhere.
"If you get a call out it could be like £150 but you could go to [a shop] and buy that same battery for like £50.
"If you put it off, you’ll be at the mercy of whoever’s got a battery near you and they can charge whatever they want."
Many auto parts outlets, like Halfords, offer free battery checks or you can even pick up a voltage checker and do it at home.
