• Lubrication

  It is essential to use the recommended oil and change it frequently. This ensures all moving parts like crankshafts, camshafts, and pistons are well lubricated. It minimizes friction and wear, reducing the chances of engine damage and improving its lifespan. Check the oil regularly for contaminants. This practice helps to maintain the quality of the oil and the effectiveness of the lubrication system.

• Cooling

  The engine needs to be cooled down after running, especially in high-load operations like driving uphill or towing. This allows the coolant to circulate and temperature equalization to occur. The engine won't be damaged, and its performance won't be affected by heat stress. The cooling system also needs to be checked regularly for leaks or blockages. This ensures that it works efficiently and maintains the temperature of the engine within the optimal range.

How to choose ee20z engines

Choosing a suitable EE20Z engine for resale requires consideration of several factors to meet the target customers' needs. Here are some of the factors to consider when choosing Subaa diesel engines for resale.

• Model Specifications

  Subaru introduced the EE20 engine in 2008. It is a four-cylinder engine with a flat-four (boxer) layout. Before choosing the engine for resale, understand the specific features of each model. For instance, the EE20Z engine has a long stroke and ample low-speed torque, making it suitable for heavy vehicles. The EE20 engine also has a turbocharged intercooler, which increases the intake air pressure and improves the engine's efficiency and output. The EE20Z engine is mainly used in large vehicles such as buses and trucks. If the target customers are bus and truck owners, it is better to choose the EE20Z engine.

• Condition

  Inspect the engine's condition to evaluate its wear and tear. Look for any physical damages, rust, or corrosion in the engine block. Thoroughly examine all the engine components, such as the piston, cylinder head, camshaft, and valve spring, to see if there are any cracks or need replacement. Check the engine's mileage since the wear and tear are directly proportional to the engine's mileage. Reselling engines in good condition without any major repairs or overhauls require less investment.

• Modifications

  Some dealers modify the engines to enhance their performance. For instance, the piston and cylinder head may be replaced to improve the engine's compression ratio. The camshaft may also be changed to enhance the intake and exhaust valve timing. Modifications may either limit or increase the resale value, depending on the market demand. If the target customers are looking for high-performance engines, modified engines can attract a good profit margin. On the other hand, modification can discourage potential buyers who want the engine in its original condition.

• Documentation

  When reselling engines, it is important to have the necessary documentation to comply with the local laws and regulations. Find out the required documents to show proof of ownership. In some regions, a receipt from the previous owner is enough, while others may require a certificate of ownership transfer. Additionally, inspect the engine to see if it has the necessary compliance and quality certification. For instance, emissions certification shows that the engine meets the environmental standards set by the local authority.

How to DIY and Replace ee20z engine

Replacing the Subaru EE20 engine is a complex task that requires expertise in automotive mechanics. The EE20 engine is a diesel boxer engine used in various Subaru models. Here are some general steps to replace an EE20Z engine:
