How to Warm Up a Car in Winter?
2 Answers
Methods for warming up a car in winter: After starting the engine, wait briefly in place (the waiting time depends on when the RPM drops to a relatively stable level, usually no more than one minute). The engine RPM should remain within the range of 2000 to 3000, with the RPM being basically stable without significant fluctuations, and the car body should not exhibit noticeable shaking. Under these conditions, you can shift gears and start driving. The main reason for warming up the car is: After the car has been parked for a long time, the engine oil flows back into the oil pan at the bottom of the engine. Upon starting, the upper part of the engine is in a state without oil and lacks lubrication. It takes about 30 seconds after starting for the oil pump to circulate the oil to the engine components that require lubrication, such as the pistons, connecting rods, and crankshaft.
I'm quite good at warming up the car in winter, mainly to protect the engine and keep warm. I usually let the engine idle for a minute or two after starting it, so the oil can better lubricate the engine parts and avoid wear caused by cold starts. The warm-up time shouldn't be too long—experienced drivers say no more than two or three minutes, then drive slowly for a while to let the water temperature rise gradually. This saves fuel and avoids waste. Remember to check if the windows and lights are frozen—safety first. In cold weather, starting the car early can also help the AC warm up a bit, but don't expect immediate warmth; wait a few minutes, and it'll get better. Doing this before each drive ensures the car won't have major issues all winter.
