radiator fans ?

jacabean, what model year is your 996?

My boxster's cooling system works just like yours and my needle even goes to the right side of the 0 in 180 in 100+ degree heat in standing traffic. Some of the needle position has to do with how it was put on the gauge in the first place... the needles in our gauges are not pinpoint accurate.

My 996 is an 01 3.4 . I love this car and it handles great with the PSS9s and GT3 bars . I think it handles much better than my boxster S with the ROW MO30 in the tight stuff.

Most of the info i got is that the temp swings are normal and that the early 3.4 motors tend to run a little hotter than other M96 variants. still a little concerned about how it just shoots up . In The winter time It take forever just to get the car up to temp.

When the A/C is on, the low speed fans run continuously.

When the A/C is off, the low speed fans start running at a certain coolant temperature. They may be enough to keep the coolant temperature from rising much further depending on outside temperature and speed.

If they don't, then the high speed fans will start running at a somewhat higher coolant temperature, Another forum member or a search may say what those trigger temperatures are.

I have an issue with my right side fan not running at low speed. This results in in a +5 to +10 coolant temperature. When I turn the A/C on, both fans function and the temp drops to normal. I was under the impression that the A/C turned the fans onto high speed? I have a '97
