As i reported earlier, I completed the overhaul of the a/c, but now I cannot drive more than a couple of miles before the temp. gauge goes up into the red.
My first thought was that the thermostat had chosen this moment to quit,
but then I realized that I had overlooked bleeding the cooling system. I
have now followed the instructions for bleeding the system, but the
overheating problem is still there. Moreover, we had made four trips of
20 miles or so after fixing the a/c and before the overheating problem
reared its ugly head.
When the temp. gauge shows approx. the normal temp. (half scale), the
top rad. hose is hot while the lower hose is only slightly warm. Doesn't
that indicate a thermostat problem? -- although I found a suggestion
online that due to this vehicle's design air in the system can cause the
same problem -- but even after those runs without a problem? How come
the problem didn't show up then if it was due to air in the system?
