2003 WR450 overflowing coolant and smoking.
Posted August 05, 2007 - 06:00 AM
I have very little mechanical knowledge. My 2003 WR450 has started to have an overflow of what looks like coolant out of a tube in the front of the bike. The liquid then hits the radiator or other hot metal area and smokes.
This happens after the bike sits still while running for about a minute, usually after I have been riding for ten minutes or so.
Is this normal? I mean, it's water cooled so does it need to be constantly moving to avoid this?
Thanks for your help!

The slightest bit of air moving through the radiators has a big effect. sitting still with the bike running will simply boil the insides of your motor.
Definitely check your fluid levels, then be sure to shut it off or keep moving.

How do I check to see if my coolant level is high enough? And, since I don't know what coolant type was used before do I need to drain it all?
Thanks all, I gave you some good feedback for helping me, much appreciated.

Check right side engine case for signs of leak. Read stickies at top of this forum and down load service manual if you do not have one.( save you a headache late at night).
Drain and repalce coolant with quality Motorcycle coolant avalible locally. Replace radiator cap with OEM radiator cap.
If coolant catch can (resivoir) is missing PANIC and post what you found and ask for more help:banghead:
