coolant leak
 

Ive seen other threads on this but not sure if it is this or if its a common thing..

my leak is a fine spray over the top part of the bike ie.ignition switch and coolant bottle area and it is wet on the cross members of the front part of frame .It looks like it is the coolant bottle.ive checked and changed hose fittings rads ok etc ..could it be the coolant bootle leaking on the seame or the cap..

Is the atmospheric sensor supposed to move at all ie is it fixed in or just sit on rubber mounts...

Any help is much appreciated ..if it is the coolant bottle any one got one for sale..:)


Simon

Yep,could be the header tank.Check the breather outlet is not blocked.Mine split all the way down the seam.:(

Thats what i first thought but said na cant be split.It was mostly wet on the incave section of the tank ...I did clean the crap of around the seam and it seemed to be a bit more spray so maybe this is the problem..anybody got a decent spare for sale..:D:D:D:D

Simon

yep, its the coolant bottle, there is a seam that runs around it horizontally, that eventually gives, it's very common, new ones ae only £16 or so if i remember rightlay .... bitch of a job though as the ignition comes up, tank removed, airbox (i think) .... hoses and lots of faffing ...... have fun ....

Cheers i wiil check that as well ...;)

Simon

yer found that out lastnight removing it to check things over.....:flame:

Simon

oops sorry wrong quote...:lol::lol:

meant the one about removing the header tank.doh...:lol::lol::lol:


simon

ha ha ha ... no worries ....

Right ive stripped it all out:o the two pipes on the left of the tank are ok.

The tank itself seems ok cant see any gaps in the join but im not sure ya gonna be able to anyway..:puzzled:

but i did notice that the pipe from the bottom of tank to top of rad you could actually twist ,the clamps are as tight as they wil go but are a bit rusty..
will change these but should i change the header tank just to be on the safe side as its all stripped out ..Is this a part that a dealer would stock or would i have to wait a couple of weeks

Simon

i'd say it'll still be the tank. There's another area that goes to, about 10mm-15mm above the seam, just below the lock assembly.
The hose usually turns on the rad connection pipe, although i've not seen a leak from there.
JHP usually have stock, and I think I have one to if you get stuck. I think they are about £23 now..........

When/is you do swap the tank, be careful removing the pins that the air pressure sensor mounts to. They can be very tight and they aren't very strong.

Will defo change tank just for piece of mind....had the pins out just to see what is under them luckly came out easy...will get new hose clips just to be on the safe side ... will be in touch if no joy in the morning....


Oh just fitted new bling carbon fibre sprocket cover (vented) and heel plates (look nice next to the sps type heat shield)...now what else can i find on fleabay:lol::lol:

simon

Well had the tank pressure tested today at velocie (after i told them how to do it ):puzzled:...there a pin hole were a crack is forming on the top of the tank where it starts to bend if that makes sense ...
They have ordered me one (vor should be here weds so they say .)

Also asked them about a clutch cylinder overhaul kit as mine is starting to weep but they have stopped doing them but if you contact a brembo dealer they said they can still get them......:puzzled:

or should i buy a new cylinder:)

Simon

You can't get service kits for any of the road brembo gear anymore. You have to replace the whole unit.
Are you talking about the master cylinder (handlebar) or slave cylinder (engine casing)???
If it's the slave, Evoluzione do a good repair kit that doesn't leak.

Yes its the slave cylinder ..slight weep ,only a little but its enough...

The slave isn't Brembo. It's a Ducati part.
The Evo' pistons are pretty good bits of kit. £18 and a hour at most to fit. You can buy a replacement piston from Ducati but it'll cost about £25 and it'll leak again :(

cheers look like evos the way to go..do you have a www.etc for them

cheers Simon

ps did give the bike a damn good clean as its all striped :saint:

ha ha ha, I love this .... Nelly owns and runs Cornerspeed .... www.cornerspeed.co.uk ring him tomorrow and he will organise you either an Evo piston for the standard slave or if you want some bling get a Cornerspeed uprated Slave, Nelly is my 1st call for all things Ducati ....
