The cold that is plaguing these last few days, the Iberian Peninsula, in addition to almost all of Europe, has caused us to hide from the cold more than usual, with temperatures well below zero degrees in many points. So cold has made that we have even been able to see snow in municipalities where it was half a century that I wasn’t a flake of snow. I wonder if we have given our car the attention it deserves in these situations.
As you all know, boot a heat engine when it takes several hours standing involves several efforts for the same. To be “cold” lubricant is thicker as should be found under normal operating conditions. It is for this reason that, despite the fact that we lose fuel, it is recommended wait a few seconds since we put it up until we start. In the following video, with a thermal camera, we can see how it is gradually taking temperature.
heat engines are designed to function properly at a coolant temperature of around 90 degrees. It is not necessary to wait for the fluid coolant to take that temperature to initiate the march and that the oil is also hot, but after a night of frost will always come well to leave several seconds or even a couple of minutes. In that space of time the oil will be moving, warming up and reaching all the corners, which extend the life of our engine.
In this video, and thanks to the thermal imaging camera, we could see that the driver of a Subaru has cost close to 5 minutes to let the idle range normal after having spent a night hovering around 6 degrees celsius negative. It is important to remember that if normally your car is in cold climates you’ll need, in addition to leave it booted for a few minutes before starting the ride, use refrigerant fluids proper to this climate and also specific oils. Your engine will thank you. Oh, and don’t forget to treat him “with love” (without sudden acceleration or stretching out the gears) until it is near its optimum temperature.
