i think its time for me to learn how to flush out the coolant and the brake fluids. could someone give me some hints on how so to do this or have a link to a website which shows how to D.I.Y thanks a million
coolant is easy...open radiator cap, then unscrew the drain plug. if its a 2kr then its underneath near the gear lever. im unsure where the 3ln one is but just follow the coolant piping etc. once u drained all the coolant i flush it with water till it runs all out then just put everything bak in n fill up. run engine for a few mins then top up. as for brakes, i dunno...havent done it yet...lol...but check the fzr400 manual, im sure its pretty much the same dave
Brakes are not quite as easy. You will need to get a bleed tube first (1.5 meters is a good length) - available at any hardware or auto store. And also get some dot 4 brake fluid. And a spare bottle (an old milk jug is fine). You will need to do 1 brake caliper at a time , and 1 valve at a time (I think the front has 2 valves). If you feel comfortable with this then you can do multiple calipers at a time (though still only 1 valve per caliper at at time). The reason I say do one at a time to start wtih is you do not want to let air into the braking system - that is a very bad thing! 1) Remove cap from brake fluid reservoir. 2) Hook up the bleed tube to the valve found on the caliper (on either front or rear) and place the other end in the bottle. if there are 2 valves on the caliper I know you are supposed to either furthest from the reservoir OR closest to the reservoir... (I forget which - I have in the past done the one furthest first) 3) Open the valve and wait. Some will say pump the brakes, some say hold the brake on, others will say wait. Whatever you choose it will slowly but surely drain out. As it drains constantly top up the brake fluid reservoir - as I said before make sure that air does not get in!!! 4) Once the fluid coming out the bleed tube is bright green then it is time to re-close the valve. To do this hold the brake lever on, and then close the valve (otherwise you won't have any brakes). Then move onto the next one. (if you see any bubbles coming out in the fluid you will have to wait till they dissipate before closing the valve). It takes time - about 10 minutes per valve. Just be patient. And before you go out riding again check your brakes to make sure they work! And finally - don't let the brake fluid get on any fairings or paint work - it will eat away at it. So it is wise to have some spare damp rags just in case.
Garfield - I hope you don't mind but I cut and pasted your coolant flushing into the 'how to' section.
hi guys and gurls. my coolant is low at the moment and i was wondering if its possible just to top it up with new one or is it better to flush it out then add the new one in. any help appreciated.
You can usually just top it up. I have heard a warning that you should not mix different types of coolant, however from what i have been able to read this refers to mixing regular coolant and types like anti-freeze coolant (your coolant should be green, and so should the stuff you add. Anti-freeze coolant is usually a red). So if you add just regular coolant you should be fine. I tend to buy the coolant concentrate and mix it to a bit higher than specifications (i.e. 50/50) rather than the 30(coolant)/70(water) mix recommended. Not sure if this has any value but it is what I was told initially to do, so I have kept doing it.
hey, i've heard you should never mix coolents because they can make an extremely corrosive mixture and completely screw up ur bike... so just as a safety measure you way as well just flush it out... the coolant only costs about 5-10 bucks anyway
