Coolant Leak Answer

[@clivegreenall309]

Thanks from S.Africa. Wish I'd seen this a couple of months back it would have saved me a lot of lost time with having to return my bike twice r to the garage. Keep the videos coming.

[@cohiba7687]

Hey champ thanks so much I just bought my bike and looked down and bingo a leak. This video is great. The manual is no use thanks mate

[@jal1992]

GREAT video man. I had just replaced my seals while replaceing a torn pressure seal, and i had put them in backwards, so the openings were facing each other. I went to start my bike and it poure3d fluid. now i know the correct way and why its the correct way. Thanks man

[@thedubs47]

I knew it would be a seal, but with your help now I know exactly which seal it is! thanks

[@Tooextrememx]

Thanks the high flow impellars are great they keep your quad running cooler.just don't get too nervous when your fan don't turn on as often as it used too.

[@alanam9230]

are those seals called water pump oil seals and are they the same seal just a quantity of 2 seals?

[@Tooextrememx]

@gusocorredor A dealer could charge anywere from $70-200 bucks including parts. If you do it yourself it would cost about $20-40.

[@Tooextrememx]

@25Davidh you don't really wana use gasket stuff where a fiber gasket is required.i can be done but most of the time it starts leaking not to long after u do it.you can usually go to a dealer and order just the 1 gasket you need instead of buying a whole kit and it would only cost you around $10.

[@Tooextrememx]

cars are a bit differant from bikes & quads. what you can do is drive your car around for a few mins to get the engine temp up to normal operating temp and then park it on a dry section of pavement where there is no stains on the ground for about a hour.after about an hour move the car a little bit and look to see if there is a wet spot on the ground where the car was parked to see if it is leaking coolent or burning it.if it is leaking you can look at the bottem of the motor to see where.

[@touge_legendcorrea2795]

I bought a 99 wr400f street legal and the hole was also plugged up unplugged it and it's definitely leaking .. .. checked my dipstick and now there's coolent in there .. can this be from the weephole or can it be from the topend seals ? I'm also getting milky residue from the top crank case breathing hose .. plz help ...

[@Tooextrememx]

@mossow71 if you don't have coolant leaking from the weep hole you may have a blown head gasket and are leaking a little coolant into your oil.milky oil means water is in the oil.you also may have gone threw too deep of water since the last time you did an oil change.

[@darrelloliver51]

Hello I have coolant mixing with the oil,also leaking from weep hole,so which seal do I change to stop mixing and leaking ?

[@neillwolf4319]

Great video mate...exactly what I needed to see

[@dallasoswalt2856]

So im doing the seal change now...I have the case off seal,shaft,impeller, and bearing out...while I was taking the case off I noticed little metal spacers or cylinders...well as I was taking the case off they fell and im not 100% where they go? help would be much appreciated....thanks

[@rodolfoarista]

Hello that’s a great information. I have a question what about when is oil coming out from the same hole

[@Tooextrememx]

That would mean the inner seal is bad. There are usually 2 seals one on each side of the hole one is to keep oil in and other is to keep coolant in. If they both go bad it could leak oil into coolant and coolant into oil.

[@reidluckett8625]

I have a question. Are you able to replace both seals without the engine casing coming off or not possible?

[@tadastolevicius9118]

highly frustrating video quality and the camera held to close

[@mohamadchanty7717]

GOOD JOB- I AHVE A SREET ROD HARLEY AND THE IMPELLER IS FIXED ON SHAFT WITHOUT ANT BOLT, WOULD IT BE POSSIBLE TO USE A PRESS TO RELEASE IMPELLER TO REPLACE THE SEAL BEHIND? ANY IDEA T SHARE PLS

[@Tooextrememx]

@vicrsx i use a desulfator on my battery to get a bit more use out of mine.also best to always run your quad with low beams on.

[@OscarMorales-sj3ok]

I got a 2008 can am Ds 450, and my quad is leaking like that can you make a video where you take out the gaskets an replace them

[@mozellecrews6370]

Is this seal on the water pump after impeller is taken out or is is below the water pump? In other words is this seal a different part or part of the water pump? I've had an overheating problem for awhile, just changed the water pump & it's now leaking!!!An answer would be much appreciated!!! Thank you

[@Immexbeatz]

I'm having this problem on my Aprilia sr50 street. The water pump is rather similar to this one, I guess they all are, and I installed a brand new water pump. So, new seals, bearings, everything. But it leaks from the weep hole, Could it be that I didn't place the bearings deep enough, or ?

[@Tooextrememx]

@gusocorredor Yes you have to drain the oil and coolent cuz you need to remove the whole side cover.

[@weakbrainthrombosis]

I’m guessing this is the cause of oil in my coolant? How do you get that bearing out?

[@allenupnorth2191]

Did you figure it out

[@weakbrainthrombosis]

@@allenupnorth2191 yes I did. I took a socket and set it on the bearing, then I lightly hit the socket with a hammer until the bearing came out.

[@pnh6999]

Thank you for the video! We evidently had a bike that someone had the seal in backwards and put JB weld in the weep hole to keep it from leaking. Smart- NOT! We used your video to determine seal direction- THANK YOU! Also I am sorry there are haters out there that blame their lack of mechanical skill on videos on youtube video such as this one. If they cant take a seal out with out cracking their case maybe they should have used a smaller sledge hammer! LOL (or not work on bikes!)

[@deadbread8171]

Eric Swift who is gonna split the crankcase in half to put a seal in? You need to make it where I can replace the seal without having to tear the motor down. Can you do that since you calling people haters because your instruction video is more than I want to do. And I am mechanically inclined I work on my own stuff.

[@gusocorredor]

@Tooextrememx hehehe, im a little far from your cold winters, its summer now in the dominican republic and temp goes from 30-40 Celsius but feels a lot hotter due to humidity.

[@scottostrander9269]

So my water pump hose is dripping oil. Does that mean the inner seal is bad?

[@Blekk1989]

thank you for your video mate,i ran in a problem with my 2005 400 E.I have a huge amount of water in my oil tank.Water kept disappearing from my radiator/overflow tank.I will check this,might be the issue

[@noelstrailridingxperience5279]

So check for rust on the bearing in order to know if both seals need replacement or just do both?? The outer seal can be done without removing the inner clutchcover right??

[@AdrianA-pg7fe]

Great explanation. Thanks. I think I have this problem. To the shop it's going soon.

[@benny8300]

Many forums have said its normal on the yfz 450 to leak until the engine gets warm to expand and it stops leaking

[@richardmichaud7972]

I am at 218 Yamaha grizzly 700 Prestone is leaking from the magneto cover so its the seal are done???????

[@3MatthewWright3]

Just did my seals and took off my case and clutch cover, I reuse both gaskets only because they where in good shape still and I had silicone grease to help seal

[@sbz666_]

Do these seals just randomly go bad? I had my entire pump rebuilt 2 years ago. Couple weeks ago I noticed a small amount of coolant leaking so probably that outer seal going bad. How did it go bad in 2 years? I'm a weekend warrior type rider, just a few hours on Saturdays on the trails, nothing intense. I did let it sit in a storage unit in the Arizona heat for ~3 months this summer... but the coolant has to get hotter than the ambient ~120F it gets in the unit, right? Can they dry out from lack of circulation? Just want to make sure I don't have to do this again next year lol.

[@Tooextrememx]

yes they can ive had seals fail after only a few months this can happen due to improper installation,poor quality material,defects in manufacturing ,or even impeller shaft damage/wear that wasnt noticed when being rebuilt.

[@gusocorredor]

@Tooextrememx do you ride in the woods, shade??? i ride in sugar cane fields so no shades, only a couple which is like heaven when you do pass through

[@Tooextrememx]

@gusocorredor It could take a few minutes to a few weeks. It is one of those things that when it starts you want to fix it rite away befor anything bad happens.

[@kenweis7913]

The mechanical seal goes bad when it runs dry.....the 2 pieces are carbon n ceramic the carbon pits out......seals are 20-50

[@Tooextrememx]

@slicksavage25 it is posable that water got into the engine i would drain the oil and check it might have caused it.you might wana check out my Important Info for 04-06 YFZ owners video cuz that might also have been the cause.

[@MrTJ1695]

I got an old 86 bronco ii and I recently started it up , walked around it and noticed two small greenish clear puddles under it between the waterpump and the fan , whatchya think about that

[@dirtbikeevent7162]

Is that a Boyesen impeller? Does the boyesen impeller need the Boyesen housing? does impeller cause leaks? does impeller need the 1/8 inch hole drilled in it to equalize pressure visa vi the 2006 and beyond impellers? Thx

[@stix746]

I have a crf 450r I changed the seals on the water pump now it's not leakin but I'm some how burning antifreeze but not oil.. Can u help me.. I'm not sure where to start with it.. Any help would be so much appreciated

[@vicrsx]

Man thanks I have that same exact problem, I'm not a mechanic but I'm a paintball marker tech, I figure this is not to hard for me to do myself nooo????? hey do you know how much a new battery for the yfz runs for it's time for a new one it doesent hold the charge any more.

[@CreatingASimplerLifeOffGrid]

What model quad is this ? Thanks

I have coolant coming out of the intake port on one cylinder on a 96 machine z 600 triple

[@dudley237]

Thanks dude, i have a kvf700 prairie and it is dripping oil slowly through the overflow tube. I needed to figure out which way the oil seal fit in there because that is what was bad. I appreciate the video. Thanks

[@Sam_Smith_Trump]

Do you know what happens if you don’t change it fast enough and it gets in the engine oil?

[@samlowell5107]

Thank you this helped outvalot having the same problem with mine, leaking from that hole, got the kit for it coming in just wasn't Shure where it was coming now I do thank you

[@michaeltamondong8572]

what if the coolant spills only when you open the cap of the radaitor

[@Tooextrememx]

@gusocorredor thats a fair labor price.where are you located cuz i think 20w50 may be a little too much if you are in the wrong area.

[@IamDtvStudios]

is there a way to take the impeller off without having to take the crank case cover off?

yes

Awesome man...I have an 83 Honda Shadow 750 which is doing the same thing,I t started w a small drip,now dumps some out while riding,ALSO,mine started to run hot and over heat,so I think maybe if the seals can leak coolant by,maybe air can also be drawn in? Felt like i just had an air pocket i could'nt get rid of,being always hot?so in short,,i am waiting for a new water pump rite now also,this video gives me a little hope this will fix it,,thanx..

[@joecruz196]

Is this a motor cycle motor???

[@johngomez2265]

I have a 2006 yfz 450,jetted. It is riding a little hotter than average and the radiator fluid is not leaking through the seals or water pump. It is leaking through a hose which is connected to the water pump? I don't know why but i fill up the tank and it slips right out through the hose

[@gusocorredor]

@gusocorredor and before it leaks to the bearing there is a seal, so its first seal then leak through hole then second seal and leaks to oil, how long can i run on it using the second seal before the bearing getting damaged???

[@AgentAceBoogie]

I got the problem with my ninja 300 I'm sure it's the exact same issue. Any advice ?

[@mmackinnon120690]

Awesome! Thanks. I had the same in my vmax. I just noticed it today, that it leaks from that small hole. I will get to ut asap. I hope i noticed it in time. I did notice some “metalic rattling sound” when the engine gets warmer. I hope this leak is not to late and that sound comes from somewhere else, like exhaust pipes.. anyways. Thanks a lot

So those seals go out it will cause coolant to be into oil filter housing?

as long as it isnt alot you can just keep an eye on the level and top it off when needed as long as it isnt often you should be ok for a bit just check you oil often also to make sure it isnt getting milky
