Thread: TDV6 2010 Viscous Fan Issue

How very odd. I’ll be interested to see if it remains working correctly

Nice one!!

Well it was working great but a couple of days ago i ran up the freeway with my trailer - pushing a little and when I got close to the top of the hill the temp gauge started climbing.

I slowed down and the temp dropped quite quickly.

When I got home I left Old Sliver idling for a while to see if the fan kicks in to "second gear". After a few minutes it did but it sounded like a half-assed efford.

Another thing I noticed today while driving in cold conditions was that the heater that was set on 24* (A/C not on) started cooling down to the point where it was just blowing in outside air as if just the cabin fan was switched on. I turned the heat up to 27* and it started blowing very warm air and then turned down to 19* which is normally sufficient. All was OK for the rest of the 45min drive home.

Not sure if this is of any relevance???

I do have a new bottom thermostat that I bought a few months back to change over when the timing belt was done, I'll be changing this over soon and see if there is any difference.

If anyone has thoughts please share.

Cheers
