Question from J.Liu:
What is the difference between pink coolant and green coolant? Must I use pink coolant for 1995 Peugeot 405? How about for 1990 Lexus LS400? Thank you.
Answer from Nulon:
We would suggest the use of green Long Life Coolant in both cars and definitely in the Peugeot.
Being a 1990 model the Lexus would most likely have had an initial fill of Toyota/Lexus Red conventional coolant.
This has no doubt been replaced by either Red or Green coolant during normal maintenance.
As it is a 1990 model my choice would be to replace it with green Long Life Coolant - but as you mentioned our red coolant will also suit this vehicle.
Correct flushing out of the old coolant is the key to good corrosion control.
