I have a '87 Vanagon, it is very reliable. Today, I had to drive a few miles
on a washboard dirt road, very bumpy. Then later in the day, I noticed a
coolant leak. It seems to be coming from the coolant tank, not the overflow
(which is now empty). But the bracket under the main coolant tank if full of
coolant and it drips down onto the ground. Are these things prone to
cracking? Is there anything else that may be wrong that I might want to look
at? Also, I guess this is going to have me bleeding the system, which I have
never done. I could use a couple of pointers there too.
