J back in 1982 I was a toyota mechanic and remember when they came out, would say at that age it is more likely a blown head gasket or corroded head, when the red coolant turned black with age it eats the gasket, also as the motor is under the seats but the radiater and heaters are right at the front behind the grill there is a lot of water hoses and they would be very perished by now.

won't ever go back into the mechanic game bad enough keeping the boys cars going, Tylers subaru I have had to rebuid the motor and replace the auto in the last 6 months.
