Title: Coolant Check
Post by: Dudeofrude on 02 February 2017, 12:06:08 pm
Just doing some routine maintenance and thought I'd take the radiator cap off to have nose. Now I've never changed coolant before or even looked at it so I'm just wondering if this looks ok?
Seems really full, especially seeing as it's on the side stand in this pic?
Also it's a weird yellowy watery substance. Thought coolant was either blue or green?
What do you guys think?

Level looks OK to me.  The small hole in lower left of the neck is the over flow.    Did you check with the engine cold or warm?  That would affect the level.

As for colour, I agree that it's not what would be expected.  Normally, pink, orange, green or blue is what I'd expect (or dirty brown?).

I'd recommend a flush and refill with new. Easy and cheap job, and you then know exactly what you've got in there.

:agree

flush and refil but the level is as it should be. The small pipe leads off to the expansion tank under the seat. That's where you should be checking the level normally.

OK thanks guys I'll go buy some coolant and get it done. Is it like the old days where you have to match what's in there or can I replace it with anything I like?
Any recommendations? I'm usually a silkolene guy so I'd normally just get whatever they are flogging haha or maybe yamalube?

for 100% peace of mind, go to a Yamaha dealer and pay through the nose for the one they want to sell you.
Personally, I would just go to Eurocarparts and get one that says its good for alloy engines.

I take its the drain plug for the coolant? I just ran the bike and took a look around and theres a little smoke/vapour coming from it?  I'm assuming it's leaking a little?

Just read an article in Fast Bikes magazine from James at JHS racing, he said use bike specific coolant as car stuff can react with the magnesium used in bike engines.

Do you think our 14 -19 year old built to a price bikes would have any magnesium in them ?

Previous owner got caught short while out on a cold ride. That's why it's yellow :-)

Thanks for the apology, reread the article and he wrote "magnesium etc" maybe he is referring to newer bikes but still thought i would chuck it out there. Mines due a change soon and i won't be putting the stuff i "borrowed" from my old place of work which went into canal boats.

If it's anything but a Silver Fazer you can use the Canal Boat stuff in them, I did hear once it can speed them up a bit, but not much.  :lol
