Coolant leak

[n8roro]

Hey guys, I noticed a puddle this morning, and the coolant was a little low. After filling the resivoir and driving on a short trip there was a steady drip that develped and is visible on the harmonic balancer. I put a bucket under and left for the day, and when I checked later the drip stopped with not much coolant in the bucket. From what I could find online I think I should replace the water pump. What do you think? Any suggestions are appreciated.

My guess would be the water pump seal is leaking. It has a small weep hole on the bottom side of the water pump shaft. Also could be water cross over manifold gaskets. That is my guesses from afar. Good Luck and Happy Thanksgiving.

Thanks for the reply, and happy Thanksgiving to you too. Is there anything else I should replace while I'm in there? There is some belt squeel while the alternator charging if I accelerate hard, could a bad water pump cause this? The belts are new. I'm a big fan of your rebuild threads, and I want to say thanks for sharing and documenting your work. I'm learning a lot from this site.

Do you have the glow plug resistors bypassed on the fire wall?

No

I will say without looking that is the belts and pulleys are getting antifreeze on them it could cause a squeal. But I would also think that a belt that is maxed out and polished is causing the issue. I have found that belts vary on each truck. I get a set that are tight when the pulley is completely collapsed and tighten it from there. It has worked for years with my trucks. No brand was any different. I did use a few green fleet belts from Gates in the past. But all belts are created about the same. if the squeal tighten them or replace them. When they get polished and smooth the tend to slip. So fix the squeal sooner rather then later. Happy Thanksgiving Good Luck.
