Hi, I just got a 2009 650 Executive with 13,000 miles on it. The running temperature shows 3 bars, is this normal? Reason I ask is because I don't think the coolant has ever been changed, planning on doing that soon.
Mine is three bars too, but I was wondering when it comes to changing the coolant is it alright to use bottled water instead of distilled to flush it? There has been a run on distilled water in Hawaii and I can't find it anywhere! HELP : )
Mochi, it's fine to flush with fresh water of any kind from a tap or bottled water. But, make sure you refill with either; pre-mixed engine coolant designed for your bike; or a 50/50 mix of the proper anti-freeze and distilled water. Suzuki used two types of engine coolant. A two year life (green colour); and a four year life (blue colour). It should be changed roughly near the time period it's required. The engine coolant not only prevents freezing, but it lubricates your water pump seals and lengthens the pump life. It also prevents corrosion and raises the boiling point of the engine coolant so in heavy traffic you don't overheat and mess up the engine. As coolant ages, it loses many of the above benefits.
I agree with Quantum Mechanic. Flush with tab water then refill with 50/50 premix. The minerals in tab water will not hurt your engine unless you leave it in there for a long time. The amount of time it will be in there to do a flush is immaterial.
I rode my 650K4 for a year and 10,000 miles until the gauge went above 3 bars. Let me tell you what one's rectum does when you see the gauge go to 5 bars and the overtemp idiot light illuminate. OK maybe I won't.
After the engine was already up to temp, it took 15 or 20 more minutes stuck in a despicable Seattle traffic jam moving less than 10mph for the problem to occur. Evidently, the radiator fan has never worked since I owned the machine. I was surprised it took so long to overheat, given how hot the 650 runs, and that it only carries about 1.3 liter of coolant, including the overflow tank.
Many people seem to have had problems with the OEM fan, and I was very unimpressed with Denso's design (usually they do a really good job, not this time). So I installed an aftermarket fan. If you're interested, read here:
