was the flush done right?
Had my sienna coolant drained and flushed. Since my coolant capacity is a
little over 12 Qts, i supplied 1 gal. toyota concentrate and 21/2 gals. of distilled
water. After the job was done he left 2 whole gals. od distilled water. The next
day i noticed the coolant reservoir nearly empty. Was this a botched flush?
