Re: Cooling system flush

["jtrealtywebspannet" <jtrealty@xxxx>]

To flush the cooling system first loosen several hoses under the car 
and drain as much of the old coolant out as possible fron the engine, 
radiater, and heater core. Tighten the connections back up and fill 
with clean water. You can do this several times and dispose of the old 
coolant properly. When the water drains out clear now you can flush. 
Loosen one of the hoses under the car and as the water is draining out 
use a garden hose to keep the system full as you run the motor. After 
a while stop the motor, shut the water off and drain as much water out 
as you can. Now refill with a 50/50 mix of water and Premium permanant 
anti-freeze. Top off and bleed. Pressure test when done. The system 
MUST hold 15 psi for 15 minuetes. Before you flush you should have 
replaced all of the 20 year old hoses and seals so you don't waste all 
of that new anti-freeze. I guess you should pressure test BEFORE you 
flush!
