Although starting an engine seems as simple as turning a key, a lot actually goes into it under the hood. Diesel engines, in particular, can be difficult to get started, which is why 7.3 Powerstroke glow plugs exist. +Read more
While a running engine can continue to run as long as it’s supplied with fuel and air, those initial few cranks need to come from a 7.3 Powerstroke starter. Issues with the starter motor may not be caused by the starter itself. As the part is electrically powered, damage to the 7.3 Powerstroke battery cables might result in the starter either not receiving enough power or not working at all. Similarly, a failing 7.3 Powerstroke alternator will result in a battery with low charge, and if the battery has too little charge, then the starter won’t be able to crank the engine.
Cold engines are harder to crank for a number of reasons. A colder air/fuel mixture doesn’t combust as easily, and as metal shrinks when it’s cold, the starter will be fighting against more friction in a chillier climate. If you’re having trouble starting your truck in winter, then a 7.3 Powerstroke starter upgrade may solve your issues. An upgraded starter can crank the engine with more force and has a better chance of starting your vehicle the first time. However, that starter will also require more power to exert its maximum force, so you may have to upgrade your battery and perform a 7.3 Powerstroke alternator upgrade, too, if you want to get the most out of your new part.
