Hi;
I found the following while searching the archives for the best way
to go about changing out that nasty green coolant the P.O. left in
my beloved "84 Westy.
1. Remove the spare tire.
2. Loosen the radiator support screws (4 of them) so that the
radiator bleeder screw is easier to work with.
3. Choose one of the two hoses running between the front and rear
heater cores, and cut it at a location close to the front of the
car. Install a "flush Tee" (available in most auto parts stores),
and connect a garden hose to this Tee.
4. In the Bentley manual, the drain plug under the engine is removed
to allow the coolant to drain. This is NOT very pleasant and the
draining is NOT easy to do this way. Just remove the two big hoses
connected to the engine block ... much easier.
5. There are two large hoses connected to the left side of the engine
block. Disconnect one of them, turn on the garden hose (see #3)
for two minutes, then re-connect this hose. Disconnect the other
large hose, and run the garden hose for another two minutes. Turn
off the water, disconnect BOTH hoses, and let the water run out of
both hoses. Reconnect both hoses to the engine block.
6. Remove the garden hose and put the cap on the Tee ... tightly.
7. There is about two gallons of water left in the system now.
8. Follow the Bentley manual and refill the system with about 2.25
gallons of 100 percent coolant/anti-freeze.
I thought this seemed like a reasonable procedure except that I've
heard that it is important to use distilled water to dilute the coolant.
Has anyone used this method?
Are there better ways to go about a coolant change?
Any comments, opinions and advice are always appreciated.
Thanks;
