Burping the excess air out of the cooling system on the old 93 Viper after changing the 20 year old coolant. It is a week-long process since the thermostat and heater hoses are the highest point in the cooling system on the car. They are mounted at the rear of the engine block up against the firewall. You have to disconnect a heater line from the heater core and trickle in the coolant a 1/4 cup at a time til you get to the full 16 quarts. You then reconnect the line, start it and run it up to temperature and then shut it off to cool down to room temperature. Wait 24 hours and do it again. It's day 5 and I am finally finished.
Dodge fixed the problem for 1994 by added a remote coolant reservoir and redesigning the system.
