TCL coolants have completely the of stability of rust-resistance. The extended long life inhibitor formulation prevents rust, corrosion, cavitation and degradation of the cooling system for 8 years or 500,000km.However, it is advisable to check the quantity of the diluted coolant periodically and in case quantity has decreased, to fill up the new coolant to keep the original density. TCL long life coolants have the durability of 2 years in continuous use.Upon pouring, after confirming the quantity of the coolant in the engine and the minimum temperature in the area where the coolant is used, add the required quantity of the coolant, referring to the table of mixture and pour the water until it comes 2-3cm under the bottom face of the radiator cap.To check the inside of the cooling system and if any leaking spot found, to repair it.To discharge the cooling water in the system completely and rinse thoroughly.Also even in summer season there occurs overheat. Therefore, no decrease in weight occurs during use. Moreover, even when mixed with water, their boiling points are above 100 degrees Celsius. TCL products consist mainly of ethylene glycol with the boiling point of above 200 degrees Celsius. Fawn Creek Township is in Montgomery County. 2nd replacement interval is 6 years/ 75,000 miles. Fawn Creek Township is located in Kansas with a population of 1,618.

However I think they misread the service interval as, 2015 Subaru maintenance schedule and new car break-in period says that. 3.TCL products consist mainly of chemicals of high boiling point. Another shop said that recommended maintenance is to flush the coolant at 75k. In addition, TCL products have excellent heat-stability, so that there occur no precipitation, rubber swelling, or softening, which lead to durability of the products. TCL products adopt special additives to prevent rust and corrosion in the cooling system, even though engines are made of aluminum, or cast iron. 2.TCL products keep antirust, anticorrosion properties in the cooling system for long hours. TCL long life coolant corresponds to classified second LLC in compliance to JIS K-2234, which has antifreezing properties for long term at proper temperature to -50 degrees Celsius according to the mixing ratio with water. A complete fill, ethylene glycol premix coolant i.e., ready-to-use simply pour.
