Title:
ENGINE COOLANT COLOR CHANGE

Models:
'02 ES 300, GS 430/300. IS 300, LS 430, LX 470, RX300 & SC430

March 22, 2002

A new pink colored LLC is being phased into production for all 2002 Lexus models.

The color change does not affect the maintenance procedures or intervals established for the red coolant. The new pink coolant is 100% compatible with the current red coolant and red coolant can be used to replace, top off, or mix in with the pink coolant with no adverse effects.

Applicable Vehicles:
2002 model year ES 300, GS 430/300, IS 300, LS 430, LX 470, RX 300 & SC 430 vehicles.
--------------------------

If you need to top off the reservoir, I'd use pink LLC or Toyota Red instead of distilled water, as distilled water doesn't contain any of the beneficial corrosion inhibitors that help your radiator enjoy a long and healthy life.
