As a result of the burning process, you are going to see the car blowing white smoke but not overheating. If the heat is increasing along with the smoke, you will have to vacate the car as well.

What Are The Reasons To Have White Smoke Without Increasing The Heat?

There are there main reasons to have white smoke from your car without raising the heat. They are, smoke caused by the oil, smoke caused by the leaking fluids, and electrical smokes.

Fuel Mixture

One of the reasons to have to blow white smoke but not overheating is the issues with fuel mixtures. If you have white or black color smoke coming out of the vehicle, you will have to check the fuel mixing composition.  If the smoke looks dark in color, you will have to check the fuel intake system. There can be a faulty sensor that allows the fuel to mix in high amounts. When it comes to blowing white smoke but not overheating, you must be having an issue with the air intake. Since the oxygen is adding lots of air along with the fuel gas, the production of the white smoke increases. In such cases, you will have to check the oxygen sensor.

Other fluids that cause blowing white smoke but not overheating

Since there are limited areas in the car that can create this incident, you will be kept to a limited area. As you already know, it is the coolant that burning off. Since the overflow tank is filled with coolant, the white smoke will occur without raising the heat.

If you feel a slight odor along with the coolant, you will have to remember that there is something else burning along with the coolant or any other fluid. When it comes to the other fluids that can be burnt, as white smoke, transmission oil, power steering, liquid-like fluids are crucial. You will have to check them when seeing a blowing white smoke but not overheating.

Electric smoke is also common.

Although electric smoke is as common as fluid-related smokes, the smoke doesn’t stay too long as the burning ends quickly. If the electric burning odor is continuous, you will have to walk out of the vehicle quickly. Because most of the vehicle’s wires are covered and insulated, you will not face such ugly incidents. But, the regular inspection of the alternator, AC compressor, and the plugs will stop seeing the blowing white smoke but not overheating.
