Coolant drip above engine- Fixed! Thanks for all your help :) - rw711 - 22-12-16
Hi I am new (put a thread on introductions a few nights ago.)
I've got a coolant drip above the engine it seems to be dropping down above no3, cylinder HT lead- then making its way out through the plug drain holes on the fins.
Gonna have to take the tank off and investigate anyway, but just wondered if anyone had any ideas? - it might save a bit of time?
also does anyone know correct diameter for exhaust clamp?
Cheers :thumbup

When you remove the tank-firstly undo the front tank mount bolt & loosen rear bolt so you can raise tank & wedge a piece of soft wood under front as a prop which gives access to the fuel tap-turn off and remove fuel hose @ tap & disconnect fuel gauge wire @ connector block. Then you can undo rear bolt & remove tank.
There are several hoses that are now visible-you should be able to spot the culprit. Big hoses connect to thermostat unit and you have a small bore drain hose from pressure cap that exits somewhere in front of rear wheel. Also, while tank is off just check condition of carburettor heater hoses-again small bore hose-although a leak from here would not run down the top of engine obviously. When refitting tank check that tank breather/drain hoses arent kinked & correctly routed. Finally top up coolant in overflow reservoir.

Hello rw711
The leak, especially if dripping over number 3 spark cylinder, is most likely to be loose jubilee clips around the thermostat housing, or a lesser chance of the filler cap not done up correctly.
If you want to do things on the quick, then just undo the front tank bolt and get someone to hold the tank up for you. You can wedge it up but it's not ideal or very safe to be honest, although i have done it myself before.
As the coolant is a sticky liquid, it will shine and show up with torch light where it is leaking from, so get the bike out of any sunlight and into the shade, or a garage, or even wait 'til it's dark, and it will become quite obvious where it is leaking from.
The jubilee clips will probably just need nipping up, or if you're very unlucky you may need to replace a pipe, but i very much doubt it.
Once you think you've found the culprit and dealt with it, give the area a wipe over with a hose and a rag, so that if the leak persists you'll be able to spot it easier next time you look.
As it's a new bike to you, once you've found the leak and sorted it, i would consider buying some Radflush from Halfrauds, and giving the system a good clean out.
It "may" be leaking due to pressure if the waterways are a bit clogged up so would need sorting out sooner rather than later.
A good tell tale sign of this would be to put your bike on the centre stand on level ground, then look under the rear seat on the right side of the bike at the coolant level in the white plastic expansion (overflow) tank.
Just give the bike a little rock and there is a lower/upper level where you should see liquid. If your system isn't air tight or is clogged up it's gonna cause problems and i'm gonna take a wild guess that either your coolant level either shows as very low or there's nothing there at all.
As you well know, with winter around the corner this is one area of the bike you want to be protected from the cold, so another good reason to make sure it's all leak free and air tight.
Any questions, feel free to ask. :thumbup
Re: Coolant drip above engine - rw711 - 22-12-16
Hi - Thanks to you both for taking the time to provide so much information. I'll hopefully be taking a look at it over the time between xmas & new year.
Yep its a new bike and new manufacturer for me - so though I've had bikes all along even the procedure for removing the tanks and layout varies
- so all these tips will save time :thumbup
Thinking of changing oil & filters - so yes makes to change the coolant too , start with a clean sheet!
- will let you know how we get on.
Re: Coolant drip above engine - Jules-C - 22-12-16
Mine had a leak there and it was the o-ring between the two halves of the thermostat housing.

That will be the next place to look, if none of above, thanks
- can you get the o-ring seperately or did you have to replace the whole thing?

Re: Coolant drip above engine - darrsi - 23-12-16
Changing the air filter is definitely a tank off job. I would always suggest a K&N air filter for these bikes, they simply run extremely well with them. And they're guaranteed for the life of the bike so it'll just involve cleaning it few and far between rather than keep replacing it.
There is always the possibility it may already have one in though so bear that in mind. They tend to be darker in colour than the standard paper ones, but should have the K&N logo on the top if there is one. Whatever you decide, do not go for the cheapest one you can find on Ebay, as you could well find that it under performs in comparison, as in it doesn't breathe well enough.
Over the last few months i've using a new brand of oil, from a British company that are obviously not too well known, but i've had no issues with it whatsoever and will be using it again from now on, i am more than happy with it. Sometimes changing oils can cause minor troubles like gear changing issues and clutch plates sticking, but this stuff has been spot on. Even better still, it's at a bargain price, there's 5 litres of it, and it's Fully Synthetic. A 100% thumbs up from me, and i am very fussy about anything i buy, so if anything doesn't reach my standards it ends up being binned. :thumbup

Another forum member posted this yesterday which was a good deal as well for an oil filter.

I've always had a ready preference for premixed coolant in my bike, but this one is very much down to the individual.
The fact that my cooling system has always remained in tip top shape over the years says to me that this stuff is doing its job very well all year round in hot and cold weather so i will keep on using it.

Obviously as it's the festive season you may have trouble getting some, if not all, of these to play with due to holidays, but there's a few pointers for you anyway.

Is it worth trying to save £10 ? against this http://www.ebay.co.uk/itm/Castrol-Power-1-4T-10W-40-Motorcycle-Bike-Oil-4-Stroke-4L-FREE-5L-SCREEN-WASH-/322328072791?hash=item4b0c401257:g:WeQAAOSwHMJYEfuF

I'm not trying to save money at all, makes no odds to me.
It would appear though that i've found a decent product without getting mugged off all because it has a known brand name on.
We've had this discussion before when i was told in a shop that 2 items, i think they were heated grips, were exactly the same product but because one had 'Oxford' packaging they could charge £30+ more.
And as i've also said before, you can't go creating oil and selling it, unless it meets strict standards and regulations.
It's good gear, trust me.
Re: Coolant drip above engine - fazersharp - 23-12-16
Yep as I said - can of worms.
But isnt the fazer supposed to be full mineral or at best/worst? semmi synth
And if oil is oil then why not wilkinsons own as that is even cheeper and everyone has a wilko near them-----can of worms
EDIT
Actually I don't think they do bike oil

Semi Synthetic is £18.99.
"...bikes that need semi synthetic oil must use at least semi synthetic but can benefit from upgrading to fully synthetic for better protection and performance..."
Re: Coolant drip above engine - darrsi - 23-12-16
Our bikes use semi synthetic as standard oil.

I always thought it was the other way round in that our bikes should use non synth BUT semi synth is ok but not fully synth.

I know, that was my whole point.
I've upgraded for a sensible cost, and i'm totally happy with it.
5 litres as well, not 4.
You can save some for your barnet.

Re: Coolant drip above engine - mtread - 23-12-16
I managed to change the air filter (K&N) by tilting the petrol tank forward and propping up with softwood (2003 Foxeye). It can be done. Agree K&N filter is very worthwhile.

Tilting it forward?
