As temperatures drop, starting your truck in cold weather becomes an unavoidable challenge for truck drivers on the road. How can you properly start your vehicle and avoid damaging parts?
Today, we’ll reveal four common mistakes people make when starting trucks in cold winter, helping you get through the winter safely!
1. Repeated Forced Starts
In the cold winter, truck batteries are already under increased load and continue to discharge slowly even after the vehicle is stopped. If you impatiently try to start it repeatedly after the first failure, not only will you be unlikely to succeed, but you will also worsen the situation and severely shorten the already strained battery life.
The correct approach is to patiently wait about 20 seconds after the first unsuccessful start to allow the battery to recover slightly before attempting a second start.
Once the engine starts successfully, do not rush to drive. Allowing the engine sufficient warm-up time is crucial. Generally, starting when the coolant temperature reaches approximately 40 degrees Celsius is the most economical and efficient.
Furthermore, develop good habits before shutting down the engine: always turn off all electrical devices such as the air conditioner, headlights, and radio. Only turn these electrical appliances on after the engine has started and warmed up. This will maximize the protection of the battery.
2. Misuse of Starting Fluid
While starting fluid, due to its volatile and low flash point properties, can indeed aid in rapid ignition and alleviate battery stress in extremely cold environments, its misuse carries extremely high risks.
After a vehicle has been parked outdoors for an extended period, the lubricating oil film between the friction surfaces inside the engine often evaporates, leaving components in a dangerous “dry friction” state.
Forcibly injecting cold starting fluid at this time will cause the engine to explode instantly, generating a huge impact that exacerbates this abnormal wear.
If the injection amount is not properly controlled, excessive starting fluid can easily lead to serious mechanical accidents such as “cold cylinder scoring” or “bearing failure,” with severe consequences. Therefore, starting fluid must be used with extreme caution!
If it is absolutely necessary to use it, the key is to preheat and lubricate critical engine components first. The best solution is to prioritize installing a fuel tank heater to preheat the fuel.
If preheating the oil pan (engine oil) is required, it is strongly recommended to use safe hot air equipment or a professional electric heating device. The use of open flame torches is strictly prohibited, as they pose a serious fire hazard.
3. Aggressive Acceleration During Start-up
Many drivers have a habit of abruptly flooring the accelerator after a cold start to “make a sound” or try to quickly warm up the engine. This behavior is akin to torture for the engine and is extremely harmful.
First, after the vehicle is stationary, the engine oil flows back to the oil pan, interrupting the oil film between the friction surfaces. During a cold start, the high-viscosity, low-temperature engine oil needs time to be re-delivered to the lubrication points by the oil pump.
If you abruptly floor the accelerator at this time, the moving parts will operate at high speed under severely insufficient lubrication conditions of “dry friction” or “boundary lubrication,” leading to abnormal wear on critical components such as cylinder walls and bearings, significantly shortening engine life, and in extreme cases, even causing cylinder scoring and bearing failure.
At the same time, the viscous engine oil at low temperatures will cause the oil pump, which operates at high speed during a sudden acceleration, to generate instantaneous extremely high oil pressure. This powerful pressure can easily damage the oil filter element and even exceed the oil pressure sensor’s tolerance.
Even with the protection of a pressure relief valve, excessively viscous engine oil may not release pressure in time, ultimately damaging related components.
Therefore, after a cold start, it is essential to be gentle and patiently wait for the engine to idle until the water temperature stabilizes at around 40 degrees Celsius before gently accelerating to prepare for starting.
