[QUOTE] Modern Honda specs are for coolant at 105K, unlike years past when they specified 30K.[/QUOTE] i wonder if i could get away with following that on my 98?[/QUOTE] No. The cooling system is physically different for newer models, designed to use the long-life coolant. The factory fill is good until 105K miles, then refills are good for 60K miles. But that technology was new with the 99 Odyssey, and was not part of the 98-02 generation Accords.
