Diagnosing overheating and weak cooling, plus the thermal systems that EVs and high-performance vehicles need. These guides cover the sequence of checks, seasonal load, heatwave demand and the thermal architecture of electric vehicles.

Frequently asked questions
What should I check first when a car overheats?
Coolant level and condition, then fan operation, then thermostat and flow. Replacing parts before those checks is how a cooling system ends up with three new components and the same fault.
Why do EVs need different cooling systems?
Battery and power electronics have their own thermal limits, so EVs use separate or combined coolant loops and often electric compressors. The architecture differs even though the principles are the same.
