Car overheating no heat
Step 1 – Check coolant level. The first step to diagnosing an overheating car is to check the coolant level. Coolant circulates through the engine and absorbs heat via heat transfer. The hot coolant is then pumped through the radiator where it is cooled by passing air before being circulated back into the engine block.To do this, set the heater controls in the car to maximum heat, remove the radiator cap (or remote mounted coolant pressure cap, sometimes on the overflow tank) and fill to the correct level.
