Hello viewers, I recently purchased a 2012 Tenere. Most of the negative issues with the bike can be sorted or lived with but I'm having trouble coming to terms with the heat coming from the engine whether stationary or blasting down the highway. I've done Kevs suggestion of wrapping the headers with exhaust wrap which helped a little.
The heat is so hot the inside of both legs gets too hot and you have to move your legs very wide to cool them down.
I've done the 02 and fuel mod and air filter stage 1 & 2 but no change.
Something odd is the coolant in the radiator is green but the overflow bottle coolant is pink....hmmm?
I tested the thermo fan by going direct to power and it works. Never have heard it come on while the bikes running though. Also the temperature light has never come on. Maybe I should get a temp gauge to see exactly where it runs.
Assuming these bikes have a thermostat I guess that should be checked next.
Would love some feedback as to how your Z's run. Admittedly I live in a fairly warm climate in Australia but I also know this is not normal.
Cheers
Brad

Odd that the coolant is a different colour in the expansion tank? I'd guess that someone has drained the coolant from the motor/rad and refilled it with a green brand, but didn't tip out the old pink coolant from the expansion tank. The expansion tank won't drain via the water pump's drain bolt, it has to be pumped or tipped out.

Even if that's the case, you'd expect (as the coolant expands and contracts into and out of the expansion tank) the two colours to get mixed up over time?

You haven't got a kink/blockage in the hose that connects the rad to the expansion tank?

I have a Trailtech TTO temperature gauge fitted, ( http://www.trailtechproducts.co.uk/a...mperature.html 19mm ID) mainly because I have a mistrust of warning lights. Generally when they come on it's too late; you've overheated. A temp gauge let's you know what going on in real time and gives advanced warning if trouble. Plus you can see when the thermostat opens and closes, as well as the exact temperature the fan cuts in on the move.

Where is that sensor attached?

It's just cut into the top radiator hose on the left hand side behind the fan.

I was going to ask same question, where did you plug it in ?

Do yo have any photos - might be worth investing in ?

Did you have to drain the system or is it doable to install it with fluid in (just top it up if necessary)

What dia is 'our' radiator pipe ??

Sorry no photos, but it's a doddle to fit; no need to drain all the coolant or remove the tank.

The unit itself is battery powered (mine's been running for three years now and still going strong), so wiring is easy. There's only one from the sensor in the hose to the display.

You only need to draw off about 250ml of coolant through the rad cap to get the top hose clear. Remove left hand grey tank cover to expose the hose (there's plenty of room to work with and a nice straight length of hose). Cut the hose, removing about 25mm in the process to accommodate the length of the sensor adapter. Clamp the adapter in place with two hose clips (supplied). Top up the missing coolant. Feed the wire through to dash area and stick the display on with the 3M pad provided. And that's it!

FYI - Internal diameter of the top hose is 19mm.

Cheers mate, as usual your advice is very helpful.

Is it connected directly to the battery and all the time 'on' ?

It has it's own internal battery and yes it's always on and displaying the temperature.

You've convinced me too, just ordered the gauge off eBay ($40AU). Also have an RR oil temp guage. Ta for the info

Which parameter is better to use to assess the general engine temperature, the oil or the coolant, as you can buy a thermometer for the oil? And once installed does it have an alarm or what is a safe top temp to be running at? Would that temp be the same for the oil?
