Is there a "how to" article somewhere on flushing the coolant on a TR650? I searched the internet but couldn't find one. I'll be flushing my coolant soon and I'm assuming it's similar to BMW GS650 but don't want to miss anything specific to the TR650. If not, I'll just go slowly and use common sense.
I'm not sure if the thermostat is removable from the radiator making backflushing of the cooling circuit problematic.
It looks removable. Just pull a wire circlip (large) on the bottom, and pop out the plug and thermostat. Never seen it done, looks doable.
In other threads related to overheating there have been instances where the whole radiator was replaced due to a failed thermostat. This leads me to believe that the thermostat may not be removable, I do know that the thermostat is INSIDE the radiator...not too thrilled with this design.
I know, and yet nobody has tried to remove one, that I know of. It's like, "if the dealer can't...". If I had a need, I would pull it. In my little 4x4, I had a pitman seal leak. Nobody would change the seal. I pulled the seal, quite easy to do, and went to the local bearing house and bought the seal and replaced it, all for about 15 bucks vs $925 I was quoted. Same with the dealers, same with electronic repair. They R$R parts for money, not to save any money. I have heard of waterless coolant. If I decide to change out, I'll give the thermostat a shot. No point in making the mess just for fun.
