leak in coolant reservoir...possible to fix?
Posted September 13, 2007 - 09:47 AM
since a few ride I have noticed the level in my coolant reservoir dropping quite fast to just under the low level mark, and then going down much more slowly....I was quite worried as I did not notice obvious leaks (coolant on the floor of my garage), and was fearing a faulty head gasket or worse....
Luckily (sort of), it is nothing serious: today I had a short commute trip to office (road only) and overfilled a little bit my reservoir before going. I identified a leak in the coolant reservoir itself, which has escaped me before because it is at the high level and was hidden by the mud during my last offroad rides...when I cleaned the bike the coolant was already under the leak point so I saw nothing....
There is no hole, rather the reservoir has split along its central welding line (it seems made of symmetric plastic parts (left and right), welded...maybe a faulty plastic welding...or a hair crack due to vibration?). This is invisible under normal circumpstances, and the leak is very small, almost non-existent when the bike is not running....but I guess it is more significant under vibration and large if I compress the reservoir manually (I can see the 2 part separating and coolant going out...).
Do you think it is possible to fix this, rewelding the reservoir using heat? (glue seems a bad idea, I guess it is polyethylene and gluing this plastic is almost impossible)...
Or do I just have to buy new a new one (I expect to be out of luck finding that stock...bad luck for the WE ...but I guess it is not expensive)
BTW I have a WR450 2004, but I guess the coolant reservoir is very similar on all WR...
Thanks for any idea dealing with this,

If other have this problem, you know that 5 minutes and a soldering iron is enough, no need to buy new part .

Lol...I love duct tape as much as anybody, but here it may be just a little too weak and not water tight enough...On the other hand, everybody know it is perfect for fixing a split frame or swingarm ...
