antifreeze boil over

Always after riding my antifreeze boils over and out the tube onto the ground. It started doing it once i put in peak antifreeze. Could this have caused the problem. Does it only take a special motorcycle antifreeze? Was i supposed to dilute the antifreeze 50/50 or leave 100% antifreeze? Thanks

Hey tchfall, Using "Car" Antifreeze Will Probaly Eat your Pump Seals, They have a Lot of Silicates[ Could be the Wrong Word or Misspelled ] I would Stick with a Motorcycle AFreeze. I think all of it Needs Diluted 50/50, If your Runing it Straight ITS WAY TOO POTENT, Change it to a Motorcycle Spec RIGHT AWAY, Dont forget to Bleed all the Air Out Too, Any Air Bubbles will cause it to Boil Too, Later Rocky

Anti-Freeze

tchfall,
I'd be looking at the radiator cap and checking its pressure release rating/serviceability. When the engine has stopped the cooling fluid stops circulating and a considerable amount of heat soak will occur and this in turn raises the pressure within the cooling system (this is why you often hear car cooling fans start up immediately after its engine has been turned off).

As for the cooling fluid, you should be following the instructions on the container. The fluid’s mix ratio recommended by the manufacturer is designed to cause no ill affects to your system (car or bike) and thereby minimising their risk to customer claims for damages. These ill affects include those such as corrosion due to a weak mix, split radiator cores and other ‘freeze’ damage due to a weak mix, seals and other component damage due to a excessively strong mix etc.

Ethylene Glycol is a substance I refuse to use in any of my vehicles because it has been known to cause damage to some rubber products within cooling systems. I use radiator coolant for their corrosion inhibiting properties only ‘cause here in Oz I rarely encounter sub-zero temps. Whereas you fellas need the anti-freeze so the Ethylene Glycol is probably unavoidable unless you can find an substitute for it.

One Word...

One word.
Thermostat.
Your twenty year old thermostat may have been over heated one too many times. This changes the molecular structure of the spring in the thermostat preventing it from opening all the way. or even at all. If it doesn't open then the system will not flow causing your coolant to boil and then overflow.
Most coolant is premixed and doesn't need diluting. This allows most owners to do minor inspections and servicing on there own. In any case, ask the counter clerk.
Most importantly, use the coolant that came in your vehicle. If it came with green, use green. If it came with purple, use purple.
These colors aren't just for looks.
They are used to identify the type of coolant in the system, relative to the requirements of the engine.

I have been riding half the summer with a little car antifreeze in it. But i am going to change it right away. How do i bleed that air out? I have a 97 600. Do i drain everthing out, then put in motorcycle antifreeze? Is there any special way for a complete flush?

How can i tell if the pump seals a bad? Also are the pump seals hard to fix if they are gone?

Thanks

Thanks for all your help. I flushed it today, put it in and it works great now. Rode it like hell, pulled in, shut it off and no boil over. Thanks

I'm fortunate to be real close to the Iron Pony retail store. Talk about a kid in a candy store. I was just in there the other day and picked up a couple of half helmets just to wear around the suburb. I almost asked the salemans to open the case so I could try on a $600 helmet. I can't imagine what a $600 helmet feels like over a $150 one.
