I know this has been discussed before, several times. I've read those threads on several forums and I'm still having issues. And, of course, it's the bolt that's impossible to get to!
So, 360 in a D300, final stages of rebuilding the top end.
The bolt behind the lower radiator hose neck on the water pump was leaking. I tried a couple different things, retorque, new thread sealer, neither worked. I decided to remove everything, check to see if I had cleaned things well enough the first time, and reinstall. I could have cleaned things better the first time, the second time things are pristine. Threads in the block have had a tap run through them to clean them out, all traces of gasket and corrosion is gone from mating surfaces, bolts are torqued to 35 ft lbs per Chiltons guide. All of the bolts seem to be holding correctly except the same darn bolt, the one behind the lower radiator hose neck on the water pump. The one that requires pulling the water pump to deal with.
I've tried with and without thread sealer. This time I decided to try gasket maker. Still leaking.
I'm 99% certain it's from the bolt and not the hose. It appears like water is bubbling around the bolt but I suppose it's plausible that it could be coming from the hose and wicking around the head of the bolt, but it doesn't look like that's what's happening to me.
Any thoughts on how to plug the leak? Not looking forward to tearing the water pump off again, but I have accepted that as my fate.
