Guys:
Good afternoon.
Still working on my '78 FJ40. Today getting ready for winter here in Idaho I was going to replace the coolant. Unscrewed the pet cock and nothing came out. Using an ice pick I managed to dislodge what must have been years of dirt and slug. Liquid came pouring out but I only got about 2 gallons. I replaced the pet cock and fill the radiator with distilled water (around 2 gallons filled the radiator), ran the engine to temp and drained again. I still only got out about 2 gallons. I know the capacity is 19.9 quarts or just shy of 5 gallons. Am not letting the engine get hot enough?
Given this is likely the 1st flush the coolant system has seen, how many times should I flush before refilling with coolant.
