Actually, green and yellow are compatible.... red, however, isn't compatible
with anything. The warning for yellow coolant is that, if it is mixed with
green, it has lost it's extended life capabilities and must be serviced at
green coolant intervals.
Additionally, if green is added to a diesel with yellow coolant, an
appropriate amount of diesel coolant supplement will have to be added as
well since the yellow coolant does not require the use of the additive.
It was definately yellow and the coolant was the original green - so I
just need to keep following the original service intervals for coolant?
The manual only gives a severe warning if it is red, I checked again
and it is yellow. The front of the container does state that it is
formulated to be compatible with any color coolant for any make or
model (for what that is worth).
I only added about 2 cups.
Thanks again - Ian
