Then switch off the engine, disconnect and reconnect the battery terminal to reset the system. The "Coolant Level Too Low" warning should disappear. If not, then go to step two. Step 2: Replace the Coolant Level Sensor If the coolant level is fine then chances
Active battery cooling is a meme, most batteries have enough thermal mass that you can just chuck your accumulator in a freezer before heading out on track, get it down to 10 C and you''re set. If you''re really worried, you can get some PCM and drive up your thermal mass a fair bit for not much money, weight or complexity.
