Help! My New Car Won’t Start Because it’s Too Hot Outside!

It is usually a cold engine, which is exposed to extreme weather that is most often difficult to start. However, hot engines sometimes have problems too. Hot engines can be tough to start, and many people do not know how to deal with this situation when it occurs to their cars. I live in Texas, it is important to know exactly why it happens and what to do.

The most common reason why a hot engine will not start is because the problem is related to fuel. When your new car engine is too hot, fuel cannot circulate well, due to the way vapor obstructs its workings and therefore the engine just will not start, as it should. To keep your engine running at the correct temperature and to protect its alloys and metals, you need to use a properly designed coolant.

A new car’s engine temperature will rise until it has been turned off. During this time,the highest concentration of vapor is being circulated and chances are that it may obstruct the engine to a greater extent. Obviously, when and if you are driving in hot weather and have just turned off the car engine you may experience start problems. Here’s a novel idea; wait for a few minutes until trying to start it again. Then go and get a high quality engine coolant.

Now here’s the good news…Fuel injected engines do not experience this problem as much

Now THIS is a hot engine!

as other engines, because the fuel remains inside the injectors under high pressure. Therefore, the vehicle does not have the same issues when it comes to starting a hot engine. For most of us this is the case, but if you are having a hard time starting your car under extreme heat conditions, then it may be time to change over your old car to a newer car with fuel injection.

Just a point of note, many of the older models or the used automobiles from the 90’s don’t have fuel injected engines. Proper maintenance of its engine was the best solution for the engine temperature. It is always best to have a record of the old car’s past problems or issues to be able to get an expert inspect it properly.

Another reason why you may have an engine, which is hard to start while hot, is that it may be due to seasonal weather as refiners change from one fuel blend to another. Gas refiners often change a higher volatility fuel to a lower one when summer approaches. This is simply because hot weather causes fuel to evaporate more quickly. If refiners change back to a higher volatility fuel, while cars are still exposed to days of extreme temperatures, this may cause swift evaporation of the fuel which, in turn would create too much vapor within the engine.

…And for goodness’ sake people, check your radiator water, and keep it at its advisable volume, this will help absorb a lot of engine generated heat.

OK, that’s it. Strange topic, but it’s one that seems to be a daily occurrence for some folks under the hot Texas sun. If you are having an issue like this, you can always bring your car by for the experts to check it out.
