Toyota 7AGE Engine Specs
The Toyota 7AGE engine is a popular choice among car enthusiasts due to its impressive performance and reliability. This engine is a modified version of the Toyota 4AGE engine, which was originally designed for the Toyota Corolla and MR2 models. The 7AGE engine combines the best features of the 4AGE engine with some modifications to enhance its power and torque output.
Engine Configuration
The Toyota 7AGE engine is a four-cylinder, inline configuration engine with a displacement of 1.8 liters. It features a dual overhead camshaft (DOHC) design with four valves per cylinder, allowing for better airflow and improved combustion efficiency. The engine is equipped with Toyota’s Variable Valve Timing with intelligence (VVT-i) system, which optimizes valve timing for enhanced performance and fuel efficiency.
The 7AGE engine utilizes a cast-iron block for durability and an aluminum cylinder head for weight reduction. It has a bore and stroke of 81mm x 85.5mm, resulting in a compression ratio of 10.3:1. The engine is also equipped with electronic fuel injection (EFI) for precise fuel delivery and improved throttle response.
Engine Oil Specs & Service Intervals
Proper engine oil selection and regular maintenance are crucial for the longevity and performance of the Toyota 7AGE engine. Here are the recommended engine oil specifications and service intervals:
- Engine Oil Type: It is recommended to use a high-quality synthetic or semi-synthetic engine oil with a viscosity rating of 5W-30 or 10W-30. This ensures proper lubrication and protection for the engine components.
- Oil Capacity: The Toyota 7AGE engine has an oil capacity of approximately 4.2 liters (including the oil filter).
- Oil Change Interval: It is recommended to change the engine oil and oil filter every 5,000 to 7,500 miles or every 6 months, whichever comes first. Regular oil changes help remove contaminants and maintain optimal engine performance.
- Oil Filter Replacement: The oil filter should be replaced during each oil change to ensure proper filtration and prevent engine damage.
It is important to note that these specifications and service intervals may vary depending on the specific model and year of the vehicle. Therefore, it is always advisable to consult the owner’s manual or contact a certified Toyota technician for the most accurate information.
