发帖数: 711 | 1 a big part of coolant (1/3-1/2) is in engine block,
and can't be drained from radiator. some cars has
another drain plug and bleed plug on engine block
for this reason. or you need to take off thermostat.
it's better run clean water through the system first
to remove all old coolant and dirts.
another way is drain coolant in radiator/resevior,
add water, run engine several minutes until coolant
runs in radiator. then drain again and do this several
times, to remove all coolant in engine block. b |
