There is a dearth of information as to how to test the function of a viscous coupling installed in the Vanagon Syncro. Below are some links that might help. Starting with the best, [http://go2.wordpress.com/?id=725X1342&site=shufti.wordpress.com&url=http%3A%2F%2Fusers.rcn.com%2Fderekdrew%2Fvanagon%2Fviscous_couplings_vanagon_syncro.htm&sref=http%3A%2F%2Fshufti.wordpress.com%2F2009%2F11%2F20%2Fviscous-coupling-link-dump%2F Derek Drew’s comprehensive analysis and test procedures.]

Another approach is to measure the torque required to turn one front wheel as described in this [http://go2.wordpress.com/?id=725X1342&site=shufti.wordpress.com&url=http%3A%2F%2Fshufti.files.wordpress.com%2F2009%2F11%2Ffhps_sb46-0005-0101.pdf&sref=http%3A%2F%2Fshufti.wordpress.com%2F2009%2F11%2F20%2Fviscous-coupling-link-dump%2F link to a Volvo document]. Syncro owners are encouraged to try this test and report findings here. Perhaps a range of torque values can be gathered and related to viscous coupling behaviour.<br>

This Subaru site has a few discussions about vc function and testing, its worth a look around.<br>
