When I recently bought a 99 Nissan Quest, it seemed to have mixed up
coolant. The colour was combination of orange and green. It looks like
someone mixed the Dex-cool stuff in there. What I plan to do is flush it
as thoroughly as possible and fill it with non-silicate or low-silicate
coolant. Since it has 79K miles, and the timing belt needs to be changed
at 105K, I figured I may as well do the water pump as well at 105K. So
now, for the next 20K miles, until we get to the timing belt and pump,
I'm wondering if I should put in regular low silicate coolant or put the
more expensive Nissan coolant. I feel it's kind of a waste for 20K miles
and the eventual replacement of the water pump to put in the Nissan
stuff. What say you guys?
