one more question, is there a specific radiator cap that is needed? a certain PSI rating? size? can I pick it up at autozone or should I order it directly from kawasaki?
I would order directly from your Kawasaki dealer.

Unless you can find a direct match both in size and pressure setting.

If you find a non oem cap that fits just make sure it meets the following:


Relief Pressure 93 ∼ 123 kPa (0.95 ∼ 1.25 kgf/cm², 14 ∼ 18 psi)

Are there any bugs stuck in that grill? Get real close and see if you can look through the cooling fins. Next, did you put that crap tap water from down there in it when you mixed it?? That will form deposits in the cooling tubes. You can be fooled even if you run a hose through it and let it drain. You'll assume the flow is good, but they can still be clogged up enough to cause your problem. How many miles are on that thing?? Run an on/off switch to the fan to turn it on yourself. I do that on track days. I also rigged up a screen on my radiator.

No bugs, I (did use tap water) with water wetter before I left to the keys and needless to say thats what sat in the bike whilst I didn't get a chance to ride it that often

I tried to flush it as best I could by putting a high pressure hose and letting it flow through.

I replaced the radiator cap with a Stant's 10233 cap, and let the bike run at idle, it reached 212, then cooled to 210, then just stayed about 212 with the can coming on and off, will try to get a ride in to test it

If this doesn't work then it may be buildup in the radiator or the hoses?

You may want to look into a radiator flush kit which will help to rid your system of the built up lime and scale that using tap water has surly caused.

I have used a 50/50 blend of distilled water and plain white vinegar in the past to flush.

1. Mix the water/vinegar at 50/50
2. Fill system with the solution
3. Run engine until warm
4. Let cool
5. Drain
6. Repeat steps 1-5
7. Run clear distilled water through to rinse out vinegar.
8. Fill with coolant of choice.

This is the same as cleaning your coffee maker. The vinegar is acidic enough to clean out and contaminants and residual coolants, yet it won’t harm your seals and gaskets.

Sounds like we might have a winner

Had the same problems.
Bike overheating.
Checked thermostat, sensor, flushed the coolant, etc.. no change.
Started to worry about blown gasket.
I finally got the radiator to a specialist who cut it open, cleaned the silica deposits inside with a metal blade (had already done a chemical cleaning but no luck) and soldered it.
Since then my temperatures are back to normal!!!!!
Seems like the 636 radiator has too thin ports that clog easily.
Have your radiator checked by a specialized workshop!!!!

And then Little red riding hood bought a Kawasaki with grand-mom's insurance policy and lived happily ever after!!!!
