Having to replace an engine in a vehicle can be an arduous process, especially if you are someone with little to no knowledge of the inner workings of a car. If you happen to be a person without any experience, you really should consider doing the job under the direct guidance of an experienced mechanic or a person who has carried out the operation before.

If this is not possible, you should do plenty of research about the replacement process before undertaking this job. Get hold of a maintenance manual for the particular vehicle you will be working on, and become as familiar as possible with all the parts, procedures, and tools which are necessary for replacing the engine.

Engine Options

Before you start the process of replacing an engine, you will have to decide what kind of engine you will replace the old one with. A vehicle owner can buy either a new engine or a used one, and each choice has its advantages and disadvantages. Purchasing a new engine is likely to help the car owner avoid more engine problems, but this option will be definitely be more expensive.

Anybody who is thinking of buying second hand engines in Perth for installation, will be nicely surprised by how it will cost far less, but just make sure that you are dealing with somebody in the trade who is renowned and trusted. A third option that may work out is to avoid replacing an engine by rebuilding the current one, but the success of such an operation will depend on how much the current engine is damaged.


The tools you will need for replacing an engine are somewhat minimal, but saying that, some special tools will be necessary if the used engine has had some wear. If the engine parts need machining, it may be a good idea to send the parts out to a machine shop instead of attempting to do it on site without the right tools. Don’t forget too, that if one part of the engine is damaged, the chances are that another part of the engine is damaged as well. This is certainly true of things like head gaskets, so a complete and thorough inspection of the engine will be required.

The engine mounts should be duly inspected and then replaced if necessary before installation. And should the bolts look undamaged, it may be in your best interests to replace them anyway, as wear sometimes can be difficult to determine just by looking. All fluids in the engine will need to be flushed and replaced as well, and new fresh oil will have to be in the engine and primed properly before attempting to start it for the first time. Grab a wiring guide to make sure all the electronics are hooked up correctly, and do not hook up any electronics at all to the battery until all work is finished.

Or you can always ask the business where you bought the engine from to do the job for you!
