How Long Does it Take to Replace a Car Engine?

If you are looking to change your car’s engine, then you need a good idea of the amount of time it would take you or a professional to do the replacement. On average, one needs between 8 and 15 hours to replace a car’s engine. Obviously, the time taken will depend on many factors such as skill, car’s model, and the kind of engine work being done. Some cars are quite complicated and hence might need more time to replace than others. This article gives information regarding the amount of time it would take to have your car engine replaced.

How Long to Replace a Car Engine

If you are handy and have the needed skills, you can replace an engine on your own. However, you should note that cars are now complicated and it will not be easy for you to do the replacement on your own. Different factors such as the type of engine you are replacing and your car’s age might lead to complications during the installation process. Some things that you may want to leave to car experts include grease buildup that is very thick, broken bolts, and a case of rebuilt engines.

As earlier mentioned, the type of car does play a critical role in determining the time it will take to replace the engine. For instance, a simple gas or diesel engine will take a good mechanic somewhere between 5 and 7 hours to replace the engine.

Electric and hybrid cars may take longer depending on the specific elements being replaced. Trucks and other large vehicles may take 8-9 hours for full engine replacement.

You need to pay attention to other variables that affect the time needed to replace a car engine. Some of these other elements include the number of components, the vehicle’s age, and the engine’s accessibility. A complicated engine can even take a skilled over 15 hours to replace.

Factors That Determine the Length of an Engine Replacement

As earlier mentioned, several factors must come into play when determining the number of hours needed to replace a car engine. This part of the article looks at exactly that.

  • Expertise Level and Tools Used

Doing engine replacement requires some level of expertise. If you are not skilled in car mechanics, you should never attempt doing engine replacement. Even an expert will need to use the right tools to make the process easier and faster. The main equipment needed here is the crane, which lifts the old engine out then lifts the new engine and puts it into place. Engines are quite heavy and you should not try lifting them by hand because even a small gasoline engine weighs around 300lbs or more.

  • Vehicle’s Age

It is easier to replace engines in older vehicles than in newer models. The reason behind this is that old vehicles have more space to work with and simple parts and connections. Old vehicles, especially those manufactured in the 1970s and 1980s, have fewer technical aspects compared to those manufactured in the 2000s.

  • Engine Accessibility

Another thing that influences the length of time needed to replace a car engine is the ease of access to the engine and the specific connections. In some vehicles like minivans, there is less access to the engine due to the many obstacles and less space. Due to this, replacing a minivan’s engine may require extra steps, which will definitely increase the time needed to replace the engine. Tight spaces affect the replacement time and cost required to remove the old engine. Modern passenger vehicles are usually meant to offer the driver and the passenger with maximum safety and comfort. They have advanced technology and components that lead to a limited space for a mechanic to work. The type of vehicle therefore plays a critical role in determining the length of time it will take to replace a car engine.  

Engine replacement is probably one of the most challenging tasks for mechanics. Since most mechanics charge by the hour, it is good to understand the number of hours it would take your mechanic to complete the job. Engine replacement normally requires between 8 and 15 hours. However, for a well-versed mechanic, it could take 5-6 hours to replace a simple gas or diesel engine. Hybrid cars and trucks can take longer, usually 8-12 hours. It is good to talk to your mechanic so you can get an idea of the number of hours it will take them to replace your car’s engine.
