Have you checked the water pump for leakage?

No, non whatsoever. The bike runs great, and the cooling system operates wonderfully.

Yes, I did. As I stated in post #1, all motorcycle engines with water cooling have an small hole near the water pump which will ooze coolant if the water seal fails. I have repeatedly examined this inspection hole on the RX3 water pump, and it is not leaking coolant. Therefore, I must believe the water seal is in good condition.

I believe the left radiator probably had a small air pocket when I received the bike. I also believe the coolant overflow bottle has now completely filled both radiators with coolant. The coolant level in the radiators has stabilized at the full level. However, the coolant overflow bottle continues to lose coolant, but at a much reduced rate. Therefore, at this point, I am inclined to believe the evaporation theory. Will others please report if the cap on your coolant overflow bottle is somewhat loose, and will not tighten fully?

Please remember, I have now recorded about 8,250 miles on the odometer of my RX3. Therefore, I had ridden enough miles to fill the coolant in the left radiator. The coolant level in my radiators has now stabilized at full. Nevertheless, the coolant level in the overflow bottle continues to fall, but at a much reduced rate.

To me it seems counterintuitive to fill up your over flow bottle.
I'm not convinced that it can "top up" the coolant system. If the bike were to over heat and blow, I want super hot coolant in the bottle not on me so I leave mine empty so there's plenty of room But that's just me |

Excellent. Any evidence of milkshake on the underside of the oil filler cap?

I just changed the engine oil several days ago, when I passed 8,000 miles on the odometer. No, I did not notice any 'milkshake' on the underside of the oil filler cap. The bike runs cool, the engine runs great, the used engine oil looks wonderful, et cetera. I can't find any coolant leaks, and I don't believe the engine is consuming any coolant.

I do know the overflow bottle will top off the radiators on my Honda CRF250X. If the overflow bottle can't top off the radiators, why do the manufacturers always tell you to fill the overflow bottle with a certain amount of coolant?

Does the cap on your coolant overflow bottle snug securely, or does it open when you 'overtighten' it?

Just went out and checked mine, and it seems to seal good, and tight (I didn't "Try" to over tighten it, but what I felt was good amount of torque for a plastic bottle) so maybe yours is bad Spud...

Spud, the cap on my bottle tightens normally, it doesn't skip threads. I actually loosen the left side radiator so I can unhook the bottle and unscrew it, leaving the cap in place. I had no problems last week when I did this to bring the coolant up to the "full" mark on the bottle. It screwed back on correctly to a normal "tight" feel.
I think it's likely yours was overtightened at the factory and stripped. I'd try a new cap and bottle from CSC. BTW my coolant level (in the bottle) seems to have stabilized at about half-full. Last edited by NoVa Rider; 08-24-2015 at 05:59 PM. |

Only one place for fluid to go when you overfill an overflow bottle "hence the name". More than likely, as the fluid expands from heat "while running", the excess is being forced out the drain tube. The overflow bottle should never be more than 1/4 to 1/3 full. You have to allow for fluid expansion due to heat transfer. Stop filling the bottle, and you'll be fine, so will your bike.
