Just come back from the South of France. Hot.

Noticed cooling fan seems to come on a ot on my bike. In fact in heavy traffic in town, ambient temp in 80s-90s, was pretty well on continuously. Temp guage never got above 1/2 to 2/3 between normal line and red though.

Is this usual? After all I wasn't in equatorial Africa

A bit concerned as my transalp fan only ever came on twice. (Once in town in S.France when hot funnily enough).

Just would be interested to here your thoughts, especially from anyone who lives somewhere hot.

Krull, my fan (06 Tiger) comes on as soon as I'm in town traffic. It never overheats though. The same goes for my mates' Sprint.

I'm talikg British/Irish climate so it's no surprise that your fan was doing cartwheels in the South of France. Provided the bike is not actually overheating, I would consider this as 'normal' operation.

So...maybe the engine temperature is more to do with the engine itself, rather than outside conditions.

Jonny is correct. The fan should come on however often is required to keep the engine cool. Eighties and nineties Fahrenheit, plus a fair bit of humidity, puts quite a heat load on a literbike. Mid-80s and high humidity here today, and my fan was on most of the time in town too. But no problem.

The way Triumph designed the cooling system, that's the fan's normal job... not to remedy overheating after it occurs. The design of the bike would have to be quite a bit different to accomodate a cooling system that didn't require as much fan time. Since it's only needed when we're not moving down the highway, though, it's not depriving us of any engine power when it would be most important to us.

You have to be careful with this stuff as it works by reducing the surface tension of the coolant thus allowing more intimate contact with the cooling passages and better heat transfer. The corollary is that it will find any small gaps that water wouldn't seep through. With the many posts on minor leakages on Tigers I wouldn't put it in mine.

WRT the original post, my fan is on much of the time in traffic although as soon as I'm out on the open road the temperature drops back to near the line even (so far) up to 27 degrees or so ambient. I'm going to fit an LED so I can see when it's on.

Krull,

My fan and engine temp seem to act the same as yours. I am in the Panhandle of Texas and the temps have been ~100 Deg F for the past couple of weeks.

When on the highway, the temp sits about 1/4 the way up the gauge, but in town it is about 1/2 to 2/3 of the way to hot, but the fan is on all the time.

Glad to see this might be normal operation.

Those 'wetting agents' look expensive to me. And, appear to offer a solution to a non existent problem.

If you cannot live without it then try a squirt of washing up liquid, or alternatively the stuff that photographers use for washing prints.

Which contain SALT!!! Draw your own conclusion to that one.

OK, use shampoo, baby shampoo to be ultra safe. I mean how much salt does a 'squirt' of washing up liquid contain and would it cause any significant corrosion ??
