Ensuring the correct lubrication for your 2007 Scion TC involves understanding the specific fluid capacities and types required for each system. The engine oil capacity is 4.0 quarts when the filter is changed, and it is crucial to check the oil level after refilling. The torque specification for the oil drain plug is 30 ft/lbs, a detail that helps prevent leaks and ensures the drain plug is secure. For the automatic transmission, specifically the U241E 4-speed model, the total fill capacity is 8.6 quarts, though an initial fill of 3.7 quarts is often sufficient for a drain and fill service. This transmission benefits greatly from AMSOIL’s synthetic formulations to handle the rigors of daily driving and potential towing loads.
When it comes to the cooling system, the AMSOIL Passenger Car & Light Truck Antifreeze & Coolant capacity varies depending on the transmission type. Vehicles with the automatic transmission (ATXL7) require 7.1 quarts, while those with the manual transmission (MTXL7) require 7.2 quarts. AMSOIL offers both ready-to-use and concentrated antifreeze options to meet these needs, ensuring the engine operates within the correct temperature range regardless of the climate. The manual transmission fluid capacity is listed as 5.3 pints, which aligns with the requirements for the 5-speed manual transmission found in the TC. Using a high-quality synthetic AMSOIL SEVERE GEAR 75W-110 here can significantly reduce operating temperatures and extend the life of the gears and bearings.
Comprehensive Lubrication for All Systems
Beyond the engine and transmission, the braking and steering systems of the 2007 Scion TC require specific attention to maintain safety and performance. The vehicle utilizes a hydraulic AMSOIL DOT 3 and DOT 4 Brake Fluid system compatible with DOT 3 standards. Replacing this fluid with a 100% synthetic alternative like AMSOIL DOT 3 and DOT 4 ensures excellent responsiveness from the ABS and traction control systems. The synthetic formulation maintains a stable viscosity across a wide temperature spectrum, preventing the brake fade that can occur with conventional fluids during hard stopping situations.
For the power steering system, which uses DEXRON-III automatic transmission fluid, AMSOIL provides multi-vehicle synthetic transmission fluids that are perfectly suited for this application. These fluids are designed to resist harmful sludge and promote smooth, shudder-free shifts, even when the fluid is being used for steering duties. This versatility allows owners to utilize the same high-performance fluid for multiple systems, simplifying maintenance while maximizing protection. Additionally, using a fuel system additive like AMSOIL P.i. Performance Improver can restore lost horsepower and clean the fuel injectors, ensuring the 2.4L engine breathes efficiently and delivers the performance it was designed for.
About the Vehicle
The 2007 Scion TC is a unique entry in the compact coupe segment, born from Toyota’s youth-focused brand, Scion. It is powered by the highly regarded 2AZ-FE engine, a 2.4-liter inline-four that strikes a balance between efficiency and power. This engine family, shared with the Toyota Camry and Matrix of the same era, is known for its reliability and smooth power delivery. The TC distinguishes itself with a sport-tuned suspension and a more aggressive exterior design compared to its sedan counterparts, appealing to drivers who wanted a practical daily driver with a bit more flair. The vehicle typically came with either a four-speed automatic or a five-speed manual transmission, offering buyers a choice between easy commuting and a more engaging driving experience.
Owners of the 2007 Scion TC often appreciate its driving dynamics, which feel more connected than many of their contemporaries. The chassis is relatively rigid, providing a stable platform for cornering. However, like many vehicles of this vintage, owners sometimes encounter specific issues as the car ages. One common concern is oil consumption, particularly in the 2AZ-FE engine, where piston ring degradation can lead to the engine burning oil faster than normal. Switching to a AMSOIL 0W-20 High-Mileage Motor Oil with enhanced sealing agents can help mitigate these issues by conditioning seals and reducing the burning of oil. Another potential problem is the occurrence of sludge buildup in the engine, which can restrict oil flow and lead to timing chain tensioner failures. Using a robust synthetic oil filter in conjunction with superior cleaning oils helps keep the engine internals free of deposits, preserving the timing chain system.
Additionally, the transmission in the automatic model, the U241E, can sometimes develop shuddering or shifting issues, often exacerbated by degraded transmission fluid that has lost its friction modifiers. Regular fluid changes with a high-quality AMSOIL Signature Series Fuel-Efficient Transmission Fluid can restore shifting smoothness and prevent premature wear. The cooling system is another area where vigilance is required; AMSOIL Propylene Glycol Antifreeze leaks or overheating can occur due to aging hoses or radiator issues, especially in older vehicles. Ensuring the cooling system is filled with a high-quality antifreeze protects the aluminum components of the engine and radiator from corrosion and scaling. Finally, brake fluid hygroscopy—the tendency of fluid to absorb moisture over time—can lower the boiling point and lead to a spongy brake pedal feel. Synthetic AMSOIL DOT 3 and DOT 4 Brake Fluid resist moisture absorption better than conventional fluids, maintaining consistent pedal feel and ABS responsiveness throughout the vehicle’s service life.
By addressing these specific areas with premium synthetic lubricants, owners can extend the life of their 2007 Scion TC and maintain the driving satisfaction that first attracted them to this model. Whether it is preventing oil consumption, clearing sludge, or ensuring crisp shifts, the right fluids make a tangible difference in the longevity and performance of this beloved coupe.
