Does removing the engine compartment seal affect heat dissipation?
2 Answers
Removing the engine compartment seal does not affect heat dissipation, as it primarily relies on chassis openings and the grille for air intake. Insufficient refrigerant: The main cause of insufficient refrigerant is usually minor leaks in the system. If there is not enough refrigerant in the air conditioning system, the amount of refrigerant sprayed into the evaporator from the expansion valve will also decrease. As a result, when the refrigerant evaporates in the evaporator, the amount of heat absorbed will correspondingly decrease. Moisture infiltration in the refrigeration system: If moisture enters the air conditioning refrigeration system, it can lead to insufficient cooling. There is a component in the refrigeration system called the dryer (or receiver-drier), whose main function is to absorb moisture from the refrigerant.
As a car enthusiast who frequently tinkers with the engine bay, removing the sealing strip does affect heat dissipation. This component is primarily designed to prevent dust and water ingress, ensuring the engine operates smoothly in damp or dusty environments. If you remove it, airflow improves, allowing hot air to escape more easily, which might slightly enhance cooling. However, don’t just focus on the benefits—dust and moisture can quickly infiltrate, accumulating on engine components and accelerating wear and failure over time. I tried it during summer, and while cooling improved slightly, within weeks the air filter was filthy, leading to higher repair costs. In summary, modifying a car isn’t just about the perks; you need to weigh the risks. If cooling is a concern, checking the fan or cooling system first is a smarter move.
