[Vwdiesel] cooling system

[Terry Briggs]

Thanks for the replies, I let it idle awhile and the temp didn't rise 
very much. I didn't check the actual temperature with a probe though. I 
drove it about 10 miles, some of it highway at 65mph and it didn't go 
over halfway on the temp gauge. I'll hook up a temp probe tuesday and 
do it again to get an actual temperature but all seems well so far.
