I recently purchased a 1989 Wolfsburg Vanagon.  All is going good so far
but the engine is running hot.  As in the needle is about at the 3/4
mark when cruising, and can get pretty close to the hot line when stuck
in traffic.  The system has been recently flushed and filled.  What
should my plan of attack be?  Get the radiator cored?  Is there a
thermostat that could be bad?  One more thing, since it's been really
hot here (Denver) lately, I've noticed that the oil light has flickered
on and off a bit when the AC is cranked up.  Oil level is fine.    Any
ideas would be greatly appreciated.
