Is It Okay for the Engine Compartment to Get Hot in Summer?

It is quite normal for the engine compartment temperature to be relatively high in summer. Here are the details: 1. Cooling circulation system: Install a small cooling circulation system at the intake, similar to an intercooler system, to allow coolant to circulate and cool the air drawn into the engine, thereby increasing the engine's air intake. After complete combustion, the absence of high-temperature exhaust gas can effectively reduce the temperature of the engine compartment and the engine itself. A small-power fan running is better than a high-power one. 2. Accelerate combustion speed: The higher the fuel octane rating, the more inert the fuel. 97# fuel is less efficient at low RPMs compared to 93#; 97# burns slower than 93#. Most cars today have a compression ratio below 11. If you're not driving aggressively, cars with lower compression ratios can also use 93# gasoline. 93# gasoline burns faster and is more suitable for city driving than 97#. This not only reduces vehicle operating costs but also speeds up combustion, leading to quicker cooling and fewer interventions by the cooling fan, naturally lowering fuel consumption.
I've been driving for over 20 years, and it's actually quite normal for the engine compartment to get hotter in summer. The engine naturally heats up during operation, and with high temperatures adding to it, the compartment might get hot enough to burn your hand, but it's not a big deal. Heat resistance was considered during the design phase, so the materials can handle it. However, excessively high temperatures are problematic—like insufficient coolant or a clogged radiator, which can cause overheating and engine shutdown. Once, I got a high-temperature warning on the highway, and it turned out the fan belt was loose—took half an hour to fix. High temperatures also accelerate the aging and cracking of rubber hoses and can damage wire insulation, leading to short circuits and sparks. I recommend checking the antifreeze's freezing point and topping it off regularly in summer, rinsing the radiator fins with a water jet during car washes to prevent dust buildup, and avoiding prolonged idling when parked. Just keep an eye on the temperature gauge to ensure it stays steady, and you'll be fine.
