I've done a few searches about this and found a lot of references to coolant leaking from the weep hole at the bottom of the water pump housing. I'm seeing coolant pooling and dripping from where the Y-pipe tube from the radiators connects to the top of the water pump housing. There is just one bolt that holds this y-pipe in place and an o-ring between the y-pipe and the housing. I was going to drain the fluid and replace the o-ring unless any of you have other suggestions. Should I use some RTV high temp sealant as well? Should I pull off the water pump housing and replace that seal too? FYI: This is an '05 WR450F with all the free mods and 75 miles on the odometer.
