The essence of every Toyota’s greatness lies in its engine. All engines need a certain degree of maintenance but used Toyota engines need a bit extra care. However, not everyone has access to a reliable mechanic every time. That’s why some DIY maintenance tips can go a long way in helping you.

Here are five tips that will help you maintain your engine for years to come.

  • Replace engine air filter

When you find used engines for sale, you must inspect and replace the engine air filter. Even after the replacement, the air filter needs to be inspected from time to time. All you need to do is unscrew or unclip the air filter box retainers and remove the old filter. One way to see if the filter is blocked is to check if some light passes through it by holding a shop light behind it. If the filter is more than 50% blocked, replace the filter.

  • Change the coolant in your engine

Coolant change is another important part of engine maintenance. Good quality and condition of coolant prevent overheating. But just a coolant chance can set you a few hundred bucks behind. Fortunately, you can change the coolant in your engine yourself and save money while doing so. 

  • Replace the spark plugs

The used engines available for sale mostly have decent spark plugs but a few changes here and there can help you spike up the performance significantly. So, change your engine’s spark plugs yourself to maintain peak performance and high gas mileage. As long as you have the right tools, you can easily do it.

  • Clean the air/fuel intake system

If your used Toyota engine is lagging on the response and delivering a crummy idle when you put the pedal to the metal, you may have soot and carbon build-up on the valves, intake manifold, and throttle body assembly.  What you need to do in this case is clean the air/fuel intake system and allow the engine to function optimally.

  • Clean the engine block 

An engine’s outer appearance is a tell-tale sign of what could be going on inside the engine. So, if your engine block appears to be filthy with dust, dirt, and oil marks, it’s time to clean it. Use your usual cleaning supplies. Also, look at the user manual to see which parts are water-resistant; so you don’t clog the engine with water.


Toyota engines need regular maintenance and care. But if you wish to maintain your Toyota engine without calling up a mechanic every time, there are a few things you can do on your own, like cleaning the engine block, and fuel intake system, replacing the air filter & spark plugs, and changing coolant. This way you’ll put away the regular engine maintenance tasks and save some money as well.
