    3 more radiator queries

    1) Do I disconnect the lower hose from the radiator or the block?
    2) Does it matter?
    3) During the drain process should I take the thermostat out?
    Thanks, Jim
    (If this is a repeat of an earlier post I apologize.)

    take it off of whichever one is easiest, don't bother taking out the thermostat, and REMEMBER to put the BARS LEAKS supplement in the hose, not in the surge tank. Very important! Also, if its on the 93, use the green coolant, mixed 50/50, if its on the DHS use DEXCOOL, also mixed 50/50.
