dear dennis
yes other problems are certainly afoot
i purchased a vanagon with a reported new engine ... indeed less than 1000
miles on it ...
unfortunately ... the person who did the engine work replaced ony one or two
hoses and very little else ..
today i replaced all fuel lines from tank outlet to the just behind the
firewall grommet ... including new injector seals etc ..
so tonight as i was checking for perfection of fuel line replacement .... we
noticed a smoke like stuff coming from around the fitting that joins the
block to the thermostat housing ... off to part store to get new hose to
replace because some lazy mechanic fixed with some disintegrating stuff that
was decomposing and burning off ... but until now had gone un noticed due to
all the other stuff that required attention drawing our concentration ...
so what is actually wrong with thermostat .... it is seized ... discovered
by boiling and then closly inspecting under brighter light
in the pot it doesnt even move ...
this van had not moved in several years ...
so there are some issues ...
and yes tires replaced to get ride of old weathered ones ...
yours
