Finally, some good news. I put the below recovery tank in place of my overflow bottle. I put it high on the driver side
inner fender. I then filled my radiator near the top (its usually 3 inches lower when I remove cap), and I filled the recovery
tank halfway. Went out for some fairly hard driving. Came back. Recovery tank almost empty. Let radiator cool down,
removed cap, and water was all the way at the top of the radiator, touching the bottom of the cap.
So, with recovery tank almost empty when I got back, that shows I had a lot of air in my coolant sytem. Odds are for the
last 15 years, I might have been running around with only about 85% of my system full, mainly because every time
I drove it, I would get about a cup of overflow. Nother good thing, is the removal of the air may help minimize corrosion.
And now in hot summer weather, radiator may cool even better.
So, anyone with a car running too hot, this may be a big help!
Now, back to replacing the weenie fuel pump!
