Title:
RECYCLED COOLANT
BACKGROUND:
Because of increasing environmental regulations, LEXUS anticipates heightened interest in and proliferation of recycled engine coolant in the United
States. Already, many dealers are being approached by coolant recycling companies. This has raised questions regarding LEXUS' acceptance of recycled
coolant for use in it's engines.
LEXUS is currently evaluating the viability of recycled engine coolant. The evaluation process is quite extensive and takes into account several
important aspects including temperature, corrosion, lubrication, and foaming performance testing.
RECOMMENDATION
Due to the difficulty in regulating the amount of additives used in recycled coolant, the performance characteristics will vary. In addition, long-term
testing and evaluation have not been conducted. Subsequently, LEXUS does not currently recommend recycled engine coolant for use in any vehicle.
