Toyota Super Long Life Radiator Coolant 5L 08889-80490

Get Toyota Super Long Life Radiator Coolant 5L 08889-80490 in Kenya

The Toyota Super Long Life Radiator Coolant (SLLC) 5L is an advanced ethylene glycol-based engine coolant formulated to meet the specific thermal and corrosion protection requirements of Toyota engines and cooling systems. Engineered using phosphate-based organic acid technology (OAT), it provides long-lasting performance and protection for aluminum, steel, cast iron, copper, and other metals commonly found in modern engine components.

This ready-to-use coolant is pre-diluted with deionized water, eliminating the need for mixing, and is designed to deliver extended drain intervals, excellent heat transfer efficiency, and superior anti-corrosion protection under diverse operating conditions.

Primary Functions

The Toyota SLLC 5L performs several critical functions within the engine cooling system:

1. Heat Transfer: It efficiently absorbs excess engine heat and carries it to the radiator, where it is dissipated into the atmosphere. This function is vital in maintaining optimal engine operating temperatures and preventing overheating.

2. Freeze Protection: The ethylene glycol base depresses the freezing point of the coolant, allowing the fluid to remain liquid even in sub-zero temperatures, thereby preventing engine block cracking and radiator damage.

3. Boil Protection: The coolant raises the boiling point of the fluid in the radiator, offering enhanced protection against boiling over in high-temperature environments, especially under heavy load or high-speed operation.

4. Corrosion Inhibition: The formulation includes corrosion inhibitors that form protective films on metal surfaces, safeguarding the cooling system against rust, scale, pitting, and electrochemical degradation.

5. Lubrication: It lubricates the water pump and seals, reducing wear and extending the lifespan of these components.

Composition and Technology

The Toyota Super Long Life Coolant is based on a phosphate-organic acid technology (P-OAT) formulation. Unlike conventional coolants that use silicates or amines, this formula is silicate-free, borate-free, and nitrite-free, which minimizes abrasive precipitation and prevents blockages or gel formation.

Key Ingredients:

• Ethylene Glycol: Serves as the primary antifreeze agent.

• Deionized Water: Used as a carrier fluid, free from minerals that cause scale buildup.

• Phosphate Corrosion Inhibitors: Offer targeted protection to aluminum components without forming insulating silicate layers.

• Organic Acids (Carboxylates): Provide long-term corrosion protection by targeting only actively corroding surfaces.

• Dyes (Red or Pink): Allow easy identification and leak detection without affecting chemical performance.

This balanced formula ensures compatibility with Toyota engine materials and seals, offering robust protection without causing deposits or corrosion over time.

Performance Characteristics

1. Thermal Stability:

The coolant maintains its stability under extreme temperature swings, resisting degradation, evaporation, and acidification. This ensures consistent performance over long periods of service.

2. Extended Service Life:

Toyota’s Super Long Life Coolant is designed to last up to 160,000 kilometers (100,000 miles) or 5 years under normal usage conditions. After the initial fill, replacement intervals typically extend to every 80,000 km (50,000 miles) or 2 years, depending on operating environment and maintenance schedules.

3. Non-Abrasive Protection:

The phosphate and OAT inhibitors prevent pitting and cavitation corrosion, particularly on aluminum engine blocks and cylinder heads, which are vulnerable to aggressive electrolytic attack.

4. Non-Foaming Behavior:

It features anti-foam additives to maintain efficient fluid flow within the cooling circuit. This is critical in high-speed water pumps and modern pressurized cooling systems.

Application and Compatibility

Toyota SLLC 5L is factory-fill coolant for many Toyota models and is designed to meet the internal specifications outlined by Toyota Motor Corporation. It can be used in both petrol and diesel engines that require phosphate-based OAT formulations. The coolant is premixed (typically in a 50/50 ratio) and should not be diluted further.

Notable System Compatibility:

• Radiators made of aluminum or plastic tanks

• Cast iron engine blocks

• Water pumps with ceramic or metal seals

• Thermostats, hoses, and gasket materials approved for use with OAT coolants

Operational Range

• Freezing Point: -37°C (-34.6°F)

• Boiling Point (with pressurized cap): Up to 129°C (264°F)

• pH Level: Typically in the range of 7.0 to 8.5, neutral to mildly alkaline

• Specific Gravity at 20°C: Approximately 1.070–1.090

These properties ensure that the coolant remains effective across a wide range of climates, from arid conditions to freezing environments, without compromising the cooling system’s integrity.

Storage and Handling

• Container Size: 5 Liters

• Storage Conditions: Store in a cool, dry, and well-ventilated place away from direct sunlight or temperature extremes. Keep sealed when not in use to avoid contamination.

• Shelf Life: Typically up to 5 years when unopened and stored properly.

Note: Ethylene glycol-based products are toxic if ingested. Proper safety protocols should be followed during handling, and the coolant should be kept out of reach of children and pets.

Environmental Considerations

The coolant is engineered for long life, which reduces the frequency of disposal and the environmental impact of chemical waste. However, due to its ethylene glycol base, used coolant must be disposed of through approved waste collection systems to prevent groundwater contamination.

It is not biodegradable in its raw form and should not be poured down drains or onto soil. Some recycling facilities may reprocess used coolant through chemical treatment and filtration for reuse.

Maintenance Notes

• Always check coolant levels regularly and top off using the same SLLC formula. Mixing different coolant types (e.g., silicate-based or hybrid organic acid technology) can cause chemical incompatibility, resulting in gel formation or corrosion.

• If the coolant appears rusty, cloudy, or contaminated with oil or debris, a full system flush is recommended before refilling.

• Replace radiator and heater hoses as per maintenance guidelines to prevent leaks or pressure loss.

• Always ensure that the radiator cap and thermostat function properly to maintain the correct pressure and flow rate within the cooling system.
