Greetings,

I've owned my 89 Westy GL for about 2 years. The fan seems to have
been working perfectly all this time. But, last week I ascended a VERY
steep five mile road to a local ski resort. I was in low gear (auto
trans) all the way at about 3k rpms. The engine got hotter than I had
ever seen it and the fan did not cycle on. However, when I reached the
parking lot it cycled on almost as soon as I could come to a stop. It
did its thing and cycled off.

I've been off-roading many times at low speed/ low rpms and the fan
has worked fine. The problem seems to be only at low speed and high
rpms.

Anyone have any ideas? All advice appreciated.

Fred
