I am en route from Boston To Boulder in my new (to me) '90 Syncro Westy.
Coming through St. Louis my coolant warning light came on. After
immediately pulling over I discovered that the coolant in the main coolant
take had fallen below the sensor thus tripping my light. The van was not
overheating, and I found no leaks. BUT, the expansion tank is nearly
overflowing! What is going on?? Is this a coolant cap issue??

do you have the bentley manual w/ you?   it sounds like you have air in the
system. were there any head leaks prior to purchase?   i had the same thing
happen to me yesterday. was there steam/coolant coming out of the expansion
tank?   do you know how to bleed the system?
