    1998 ESC coolant question

    Should I drain or flush my coolant and what other products are used besides the coolant itself and I'm using prestone 50/50 mix with distilled water. And could anybody walk me through the steps of doing it?

    No need for a flush unless there's a blockage, or you're trying to flush out a stop leak product.

    No other products recommended or necessary, just coolant.

    Open the petcock on the radiator, drain the coolant, fill with new coolant. Correct coolant level is to the FULL COLD line on the surge tank, about half way up, where the two tank hands meet.

    Keep an eye on the coolant level for the first few drives/days, add if necessary.

    Drain and fill every 2 years, 3 max.

    After the initial fill, before you even cap it up, rev it to 3K and hold it there for 30 seconds or so to purge any air in the system. Then top it off and cap it up, but follow MC's advice and check it again after the next 2-3 drives. It could still need a top off.
