I finally got some time to check out the van. The expansion tank was a
little low, maybe down 1/2 to 1 inch, and the reservoir was a little low,
but not beneath the minimum line. I put more coolant in both and drove it
work today. Aside from getting rear-ended this morning, with no apparent
damage, the van ran fine on the way to work and in the middle of the day
when I went out to run some errands. At the end of the day, I drove down
the road and got on the 250 bypass, a 4-lane with speed limit of 55 mph.
Shortly after getting on the bypass, the light started blinking and the
temperature gauge needle rose, within a 2-mile distance, to the middle,
just over top of the blinking light. By that point, I was about a mile from
home, so I drove there and let the van cool down.
After the van cooled, I checked the oil; it was a little over a half quart
low. I hadn't checked it because I have only put about 3,000 miles on the
van since the new engine was installed. This may seem like normal leakage
to you all, but I've seldom needed to add oil between oil changes since
I've had my van and the level was fine the last time I checked it.
After adding the right amount of oil, Pennzoil 10W-40, I started it up to
move it out of the driveway. The blinking light came on and stayed on while
I was moving it.
It seems like I probably have the problem David referred to, with the
coolant level controller triggering and "poor contact at the sender or
dirty sender pins". Does this seem like a reasonable assessment to you all?
Oh, the idle has been fine all the times I drove it today, but I may not
have driven it long enough for this problem to show itself.
