Anitifreeze boiling and venting out after service.

Recently did a bunch of work on my ktm and rebuilt the water pump. After emptying all the fluids i put back in 1 liter of 50/50 mix from local Honda shop that they recommended.

After riding for a while and about 30 or so miles, came to a light and the antifreeze was bubbling out of the vent tube at a moderate rate. Enought to make a small puddle when i left. Continued home and noticed when i shut off the engine that the antifreeze was boiling . Did i do something wrong? No overheat light or anything like that came on.

FYI temp was 85+ today.

Thank you for your assistance.

Well i took both rads off and flushed them both ways to make sure there was no crapola in there during the service. They were flowing fine. and nothing came out of them abnormal.

And the fan is not on all the time. It comes on once in a while when i stop. It does come on just a little sooner than before the service.

Oh and FYI this is not the first ride since the service. Its just the first long one. I had done some woods riding a couple of times for a few hours and didnt really notice either way.

Time for a new rad cap? if it opens too soon or doesn't hold its designated pressure, fluid will boil at lower temps & will spew into the overflow. Sorry, thats the only other thing I can think of. Hopefully someone with the same bike has a good direction for you to check. Good luck

Too full?

If the radiator is too full it will puke it out as it gets heated up, till it is at the proper level. Mine settles out at a 1/4"? above the passages inside the radiator. Might want to check the thermostat to make sure it is opening.

What is the easiest way to determine the pump is pumping? Is it like a car, remove the cap and see movement?

Do you have a 1.2 bar or 1.4 bar radiator cap. Maybe go to a higher bar rating.

I am not sure if it's a cap issue, and the bike would have overheated if the thermostat was closed or the pump wasnt working and no circulation was happening at all. All of the lines were pretty damn hot.

One thing i saw was that the manual calls for topping the bike off running 10 mm above the "grid" of pipes inside the right radiator. When i put the 1 liter in described by the manual i actually only had a 920 ml bottle of AF. It never came above the grid at all and i am not sure since i completely drained the system if i should have put more in.

So... could this happen if you do not have enough antifreeze? Boiling and overflowing and such?

Kaineb,
My 2 cents.
Are you sure you are boiling?
You need a thermometer to check the temp gauge.
Fill the radiator with water, water and antifreeze, anything but get it full-not too full(a little above the plates, below the neck) .
Run it at idle, on the stand. Cap off.
Stick a thermometer in the radiator tank and check the temp.
The system will run and cool with the cap off.
Look down in the tank and see what is going on.
Note at what temp the fan comes on?
Put the cap on tight. Run the bike on the stand.
If you are really boiling when you now remove the cap all hell will break loose.
Water will fly or a hose will start leaking.
If you really are boiling remove the thermostat and do all of the above again.
Report back.
Be careful doing all this. You can get burned or wreck the bike. Just do it enough to make the tests.
bill.

Update

First off thank you all for your assistance. Really great having a world of knowledge on demand :)

I found that i needed to add about 300 ml to be at the proper level this morning. 200 50/50 mx and 100 distilled water for the proper ratio. 60/40. I ran the bike as you described (bmwktmbill) and i do see flow in there.

My thoughts that the bike was boiling was purely the sound when i shut the bike off. Sounded like it.

I ran the bike cap off filling first to the proper level with af as decribed in the maual. I found that i did see flow in there and the fan is coming on when it is supposed to.

Crud in the cap: Mine had allot when i first serviced the bike, in which i didnt do such a good job at cleaning it so i will do that now. I didnt even think of that.

Again thanks for all the help. We are making progress, just not there yet.

Resolution

Cause: Improper coolent level / mixture & Buildup of material on filler cap / radiator neck.

Resolution: Cleaned out the neck of the radiator using a punch to scrape the area and vacccum to avoid getting anything in the system. Cleaned all the seals on the cap and cleaned the indise of the neck.

Topped off the fluid level with proper mix and level and took for a long ride. No issues and no leaking now.

Thank you all for your help. I am sure the dealer would have loved to have fixed that simple issue for $200+
