What's the best procedure for flushing and filling the 05? Thanks, Doug

Get some radiator cleaner, 5 gallons of distilled water and two gallons of 100% antifreeze. You also need some jack stands, jack and a 5 gallon bucket. Only tools are a pair of channel locks.

Then drain the coolant. This is easiest done at the lower radiator hose where the 1" hose from the tank tees into it on the passenger side. You do not need to take off the plastic shield.

Fill the system with first the cleaner then straight tap water. Drive around for a while, 20 minutes to 2 days depends on how you feel about it.

Then drain the water and cleaner out. Fill with tap water and idle the engine for 20 minutes making sure the thermostat is opening. Feel the upper radiator hose and see if it is too hot to hold.

Then drain the water again and fill with distilled water. Idle engine for 20 minutes again making sure the t-stat is opening.

Then drain the distilled water. First pour in one gallon of the 100% antifreeze. Then cut the second gallon to a 50/50 mix using the distilled water and top off the system with this. Be sure to completely fill the tank and to check it again for the next couple of days when it's cold. Keep the tank as full as possible.

Excellent plain and simple instructions SHOZ. The kind a novice like me likes to see. Thanks very much! Doug

Hi Doug,
For what it is worth I used this method on my '97 Taurus that wasn't throwing any heat. I flushed the heater core first (got the infamous brown glug out of it) then used these steps. Worked great. Only thing I need now is some really cold weather...or do I? LOL Good luck and many thanks to SHOZ123 for the help.

On some of the Vulcan motors that the heater core is really clogged you may want to try using a garden hose connected directly to the heater core lines and flushing out the heater core. Just don't allow full pressure to go through it. Flush one way then the other a couple of times.

Best thing to do is to just use cheap antifreeze and change it every two years.
