'99 400 Leaking coolant
Posted May 08, 2006 - 10:34 AM
I just picked up a 99 WR400. I was idling it out in the driveway today when I noticed that there is a steady, but very slow dipping of bright green coolant dripping off the bottom of the engine case. I'd say one drop every 15 sec or so. I went around all the 8mm bolts on the waterpump side of the engine and tightened a few of them. It's still dripping. Any sugestions on where to look to find the problem? Are the water pump gaskets prone to failure on these bikes? Other than that, this bike is in great shape. The oil was clean and full and there is plenty of cooant in the overflow tank (it only seems to drip while running).

Don't ignore this because in my experience, they don't fix themselves and the peace of mind is worth the $50. Tightening bolts will do nothing to this problem.
