Hi, My bike seems to be loosing coolant from the hole arrowed in the picture. As far as I remember, it hasn't happened before, but now the coolant level is dropping and I started to worry. Any thoughts of what the problem could be? Cheers, Sergio

Problem: The info on the chain gang seems to suggest that if your bike is overheating then you change the fan switch. It seems more complex than that to me. Firstly there is a thermostat under the radiator outlet that has plastic wings to hold the spring in place. These break off pretty...

just drained my bike and it was red? is this stuff ok to replace it? it is silicate free. http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_185166_langId_-1_categoryId_229902

Some times when I have long trips, after stopping my bike and park it, I can see 1 or 2 drops of water from the left side. I first thought that it was the oring from the thermostat cover on the lower left side of the radiator because the drops where coming from there. I took the thermostat cover...

Hi can any one help! What is the the correct coolant level on a f650gs 54plate, in the maintenance booklet it says dont top up past the min mark. In the riders manual it says !Attention: always keep coolant level above the minimum mark. Which Is correct? :scratch:

Time for my bike to go wrong. Went to pick up a paper this morning, when I went to get on the bike I saw water dripping on the ground. Saw there was water left in the top up tank so rode the half mile home. Discovered that the right hand hose from the water pump area (not the one from the...

Help me please!!!! Rode up to york yesterday and on arrival noted some drips from that dreaded waterpump weaphole. I know what that means and as i have a replacement cover ready to fit, wasn't overly concerned. Coming back today however, events took a turn for the worse. When i stopped and put...

just before of a ''typical'' water pump repair on 04 Dakar, powered and sponsored by numerous tips and tricks out of f650 gs forums,at the bpoint where collecting tools and spares,so in order to choose coolant type and brand,are there any aluninium parts on the 655 Rotax engine that make the...

Hopeless at driving search engines! My '95 Funduro has started leaking coolant from the top hose (engine to radiator) while unused in the workshop. I've eliminated the radiator as there is coolant above it. The hose (what I can see) is not perished, but the paint is flaking on the thermostat...

just been perusing the workshop manual i have for the bike under coolant check, it says "Check the ability of the coolant in the expansion tank to resist freezing temperatures by checking the antifreeze concentration in the expansion tank" so, what exactly does that mean?

On further investigation ( following on from earlier post ) it would seem that my coolant is getting in to the engine oil, although the oil isn't as milky as I thought it should look but appears more grey in colour. This bike is new to me and has recently ( before I got it ) had it's head...

Can anyone advise me about the coolant level in the 'burp' tank. I have recently bought the bike and I keep topping up the coolant level when cold to just above min but when I check it again after 100 miles or so the tanks pretty much empty. I can find no leaks anwhere ( checked with the engine...

:howdy: Has anyone ever replaced the Thermoswitch on the thermostat while there is coolant in the system? I have recently changed the coolant but want to fit a new Thermoswitch before the 'summer heat' because I think the current one is faulty.

Hi chaps, Changed the coolant yesterday. (It all went well I thought, until I decided I'll "get to know the bike" and look at the waterpump. Broke a screw, with the entire thread stuck in the engine caseing. So we had to drill & tap it. Good job, everything looks fine.) Anyway – after that...

I think that you're supposed to be able to see the coolant level through the small slot in the 'tank cover' (not sure if this is the correct term) on the left hand side. I'm finding it very difficult to see the actual level without removing the 'tank cover'. I've tried shining a torch through...

Has anyone had experience of re-using the oil and coolant hoses as fitted to the original F650 ? (1995). They have a crimped on metal band to secure them to the various outlets on the engine, I'm not convinced that if they're removed and refitted there'd still be a decent seal. I was thinking of...

:think: It's been a while since I posted my last topic, but I've been reading most of your posts with interest. So I've clocked up 1200-odd miles on my '00 GS and got my hands dirty a few times in the last few months trying to fix my coolant-loss problem. I've changed the pump and seals...

i seem to be having a few strange happenings on the old beast from the east at the mo. will be posting them up over the next few days. this is one. on the left hand side of the engine (GS) you have a black rubber coolant hose. where it runs into the engine itself, theres a kinda circular housing...

Ok I need some coolant, and I know this question has been asked before but i couldnt find a straight answer? Where do I go and what coolant do I buy for my R Reg F650 ST? Thanks for replies in advance.

Hi, Rather than append to Skell's post on cooling problems I thought I'd add some information to the group. I got worried about not, using a nitrite free coolant. Also on the chain gang I read an article that showed the paint corrosion in the frame tube(through which the coolant passes)...
