Coolant Leak

[dna9656]

My 84 has a coolant leak, I think I have traced it down to the elbow; items 18 and 19 (O-Rings) on the drawing for a '84 XVZ12DKC2. About a year ago(?) I found the O-rings on the 'net during a "well if I can find these o rings they would be good to have on hand" search; so I have them on hand. I'm making this post to ask if there is anything I should look for while I am replacing the rings. I thought I would use some "Mark One lube (spit) or Vaseline to ease the o rings into place when performing the install.

Is there anything else I should pay attention to or look for? I have been using a green anti freeze, I suppose it has been slow-leaking for a while as while I was looking around I found the over flow bottle was empty but the block still had enough anti freeze to do the job. I never had a over heat condition. I plan on getting some distilled water and mixing the stuff my self. Is the green stuff the best or is there another color that's more gooder?

My thinking is that most any antifreeze is ok now due to so many auto engines being aluminum. I also use distilled water in my bike and cars.

Look for corrosion where the o-rings contact. I use synthetic on assembly.

Yes, a thin film of synthetc grease is all that is reguired to ease the assembly.
