coolant

Hey there. I did my first coolant change today. It's so satisfying seeing this blue gradient. I did a total of 4 flushes. I only managed to get over 2 liters of water out on one flush. I don't know what I am doing wrong. I think it's going to be okay for the season. Before winter, I will do one...

Hi, I recently bought a 2015 CBR650F, and after 2 hours of riding, I noticed these stains under the bike. Is it normal? I just got into riding, and it’s kind of making me nervous. Does anyone have an idea what the problem might be?

Hi, I have a 2025 CB 650r and after 1000 km I noticed this coolant leak, see pics.

Hi guys, I just bought a 2024 CBR650R (E-clutch model) and I tried to check the coolant level... but couldn't see anything (even with my flashlight) : Is there a "trick" to see it more easily ? Ps : I don't think I'm running out of coolant product because my bike was serviced recently...

Hi all, new member here so please be gentle! I just purchased a beautiful 2015 cbr650f as my first bike. I haven't passed my test yet so i haven't really ridden it apart from a small ride around the block when I bought it (6 days ago) and around the private estate at my work a little the same...

Hello everyone I just got a used CBR650R-A (2022) (6000km or 3728.227 miles) which wasn't driven from September 2023 (except when dealership was moving it around). I was ridding it the entire day and made a quick stop and saw the coolant was leaking from one of the 3 pipes at the bottom of the...

I am about to service my bike and the time has come for me to replace the radiator coolant. I was reading the manuals recommended antifreeze and saw that the manual recommends "ethylene glycol" antifreeze. I've been perusing online and I have found a coolant that I believe is fine to use, the...

I was on a ride out today with some friends we stopped for fuel and I left the bike idling as we where setting off I noticed the temp gauge maxed out and flashing then next moment a load of coolant dumped from the overflow. I left the group stopped and let it cool down then rode it home and it...

I was driving around the city during a hot day (around 35-40C) and the traffic was very bad/slow so I've been riding it at around 30-50kmh tops (2nd gear mostly). At one of the stop lights, red light for coolant turned on and I wasn't sure if I could hear the fan blowing due to all the noise...

Is anyone experiencing same thing - if i ride my bike on 8000rpm and above (never go to red anyway) - i noticed coolant droplets from drainage pipes...!!!! to be honest most of the time i ride around 6K rpm, because i dont think higher than that is good for this bike- it vibrates a lot and i...

Hi all I first noticed coolant leaking from what first appeared to be the drain plug on lower part of water pump so I gave it a little tweak with the old torque wrench which did not stop the leak so went to me local dealer £4.00 odd later swapped the 1 time use washer and refilled the coolant...

Hey! Yesterday I bought my first bike, 2021 CB650R with 6000km. Today I noticed that, there is no coolant fluid in the coolant tank. The screws next to the oil filter are blue, I think it is the coolant fluid. I only drove the bike 10km before buy, the engine temperature was normal. Still have...

guys, advise needed! suddenly yesterday i got coolant leaked thru drain pipe underneath from my CB650R!!!!!!! i tried to refill via radiator, but it leaked again as soon as engine reached working temperature!!!!!!!! now bike is coolant empty, as i checked expansion tank and is completely...

Hello everyone, I was inspecting my bike and found that water reserve tank melted and got a small hole in it, the bike did not give any overheat or anything. I don’t think it’s from the exhaust? I also noticed sometimes under my right ankle there is very very hot air. Have anyone faced this...

Dear riders, As I am enjoying my new Honda cb650r, I have taken a look at all liquid levels and noticed that the reserve coolant level is below the minimum mark when checked at cold engine (1.250km); although it is very difficult to actually see it. I had to use a direct flashlight to see the...

According to the Haynes manual, to refill the coolant on the CB650F the bleed plug on the side of the radiator is removed. However, on the CB650R, it says to remove the plug from the bleed pipe on top of the radiator. I can’t find a pipe, and can’t see it on the schematics either. Can anyone...

So today I went for a morning ride out in the country. As I was heading back home, my 2021 cbr650r did overheat and the heat bar was in the red zone, I noticed this after the bike had shut down one me while riding. I stopped safely and waited for it to cool down, which it did but now it won’t...

I bought mine from a kid. Although he seemed like he took care of it I brought it home drove it a couple times, and noticed a white substance where the head gaskets is. I’ve been watching the oil and the coolant. And I’ve noticed the coolant is more low now. The bike has 3,300 miles so it’s...
