Is It Normal for the Hood to Be Hot After the Car Is Turned Off?

1 Answers

It is normal for the hood to be hot after the car is turned off. When the engine is running, the external temperature can reach 90 degrees Celsius, and the exhaust pipe temperature can be around 50 degrees Celsius. Additionally, the heat insulation layer on the hood and the underbody panels can block heat dissipation, causing the hood to remain hot after the car is turned off. The hood serves to protect the engine and surrounding pipeline components, as the area under the hood contains critical parts of the vehicle. This includes the engine, electrical circuits, fuel system, braking system, and transmission system, all of which are vital to the vehicle. By enhancing the strength and construction of the hood, it can prevent adverse effects such as impacts, corrosion, rainwater, and electrical interference, ensuring the vehicle operates normally.

How to Replace Spark Plugs in a Tiida?

Tiida spark plug replacement procedure: Open the hood, lift the plastic engine cover, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust, and ensure thorough cleaning. Place the new spark plugs into the spark plug holes, hand-tighten them for a few turns, then use the socket to tighten them further. Reinstall the removed high-voltage distributor wires according to the firing order, and secure the cover. Spark plug replacement interval: Under normal maintenance conditions, replace spark plugs every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's advisable to follow the owner's manual. For reference, platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.

How to Use the Cruise Control in Camry?

Press the main cruise control switch, and the dashboard will display "CRUISE," indicating that the main switch is on. The throttle must be pressed to reach a speed of at least 40 km/h, then pull the control lever backward and release the throttle. The car will then maintain the set speed. Conditions for using cruise control: 1. Highways or fully enclosed roads: Cruise control is generally used on highways or fully enclosed roads, where it is more convenient. If used in congested areas, frequent braking will disrupt the stable cruise control state, making it pointless. 2. Avoid using cruise control in rainy or snowy weather: Wet or slippery roads during rain or snow may cause skidding when using cruise control. 3. Do not use cruise control on winding or mountainous roads: Using cruise control on curves compromises driving safety, as the vehicle automatically maintains a constant speed with the throttle controlled by the onboard computer, posing risks. The driver needs flexible control over the car.

What are the reasons for the Mazda 3 not responding when starting?

Reasons for the Mazda 3 not responding when starting: 1. Insufficient fuel: First, check if the fuel level is insufficient. When the car lacks its power source "gasoline", it naturally won't start. If the failure to start is due to running out of fuel, you can seek help from nearby car owners based on your situation, requesting to borrow some fuel or towing the car to a gas station as emergency measures. 2. Incorrect gear position: Generally, the P gear or N gear is the correct position for starting an automatic transmission car. If the gear is placed in R gear or other positions, the result will not only be a failure to start but also pose safety hazards. 3. Car electrical circuit issues: Common circuit faults include blown fuses, open circuits in high-voltage coils, open circuits in low-voltage circuits, detached central ignition wires, leaking distributor rotors, damaged spark plugs, etc.
