Coolant in KX500

[uncle albert]

Hi guys,
Here comes the newbie question of the month...
How much coolant does the KX500 take? Can anyone tell me?

[KX500freak]

i just fill her up till its pooring out..
then i kick it till the fluid is spread through its system.
and the manual says to keep the level just above the radiatorchannels,
guess its just under a liter going in

Going off memory I think spec was 1.4 quarts. But you can just fill it till it's full. Make sure you use the air bleed screw that is located on top of the head, this will ensure all the air is out of the cooling system (engine side). Again If I remmber correctly the 500's have a black plastic plug on top of the left side rad. I alway remove it to ensure the system can purge correctly while filling.

Here's some pictures.
Crack open bleed screw, fill right side rad. until you have a solid stream of coolant flowing out of the bleed screw, then tighen the bleed screw, next remove the black plastic plug contuine to fill right side rad. until the left rad. is full and coolant is flow over into the right rad.(left and right side rads are join together at the top with a hose).

Thats great, thanks for the info!

not sure if you fill all the way till its full.  i think there has to be a small air gap or bike may overheat (??).  i was always told to fill just over neck to leave small air gap.

It's nice to see such quality advice being handed out on such a very important topic. More then one person has fried their bike from doing this wrong, I'm sure. Two thumbs up To hughes.

d**n how do people go wrong with it...

not bleeding /kicking all the air out and then with too little coolant in it ..
they then frie it while racin,around in the dirt ?

Hughes, is that power point your using to make the text and red ovals?

It's a program called Snag It. Works really great.

Has anyone or does anyone run engine ice or anything like it?

  I have not tried engine ice, but I have used Water Wetter with good results. I used to race a military jeep with a rotary engine in it and it used to run very hot at high rpm. After improving the shrouding, enlarging the radiator increasing the air flow path, I finally tried the Water Wetter, apparently it has a chemical that helps transfer the heat out of the aluminum and into the coolant . This did greatly improve the cooling, and I am not a fan of magic potions. But in all fairness, the real solution would have been to under drive the water pump .  John

So what is everyones coolant of choice? I have been using engine ice, but is expensive...

I have been running EVANS waterless coolant for 10 yrs in my streebikes.  The coolant gives boil over protection to I believe its around 365 degrees F and is permenant.  It was designed to transfer heat faster than regular ethleen glycol.  On of the benefits is the boil over protection is with no pressure on the system.  I have modified caps to run only 2 psi on the cooling systems and have had great results with lower cylinder temps as well as its made life easier when my nephew wrecked my yz and damaged the rad.  WE managede to run it the rest of the day with no psi by just crimping the damaged fins with pliers.

No chit? Wow ok. Is that a motorcycle specific brand?

I run Engine Ice in my CR125 powered shift kart. Never needed any coolant additives in any of my dirt bikes, but my shifter kart running at 12,300 rpm's in the dead of summer heat would tend run hot and blow coolant.  Engine Ice dropped my temps about 15F.
