Beyond the engine, the cooling system plays a pivotal role in the health of this vehicle. The Celica’s cooling system holds approximately 9 quarts of AMSOIL Passenger Car & Light Truck Antifreeze & Coolant. Maintaining the integrity of this system is essential to prevent overheating, which can cause catastrophic damage to the engine block and head. AMSOIL Propylene Glycol Antifreeze and Engine Coolant products are formulated with unique poly-organic acid technology, designed to exceed OEM requirements and protect against corrosion and erosion for extended periods. The pre-mixed Ethylene Glycol version offers convenience, while the Propylene Glycol concentrate allows for customization and offers additional safety benefits due to its lower toxicity profile. Both formulations are designed to be compatible with various coolant colors and free from harmful additives like phosphates and silicates that can cause silicate dropout.
The transmission is another critical area that requires attention, depending on whether your Celica is equipped with a manual or automatic gearbox. For the automatic transmission, the fluid capacity varies based on the specific configuration. The initial fill for the A40D…AF3 transmission requires 2.5 quarts, while a total fill for the 4-speed A40D system requires 6.7 quarts. Synthetic transmission fluid is highly recommended to ensure smooth shifting and to protect against the thermal breakdown that occurs during heavy use.
