Those "old school clamps" are called "constant tension clamps." They are supposed to seal better as the temperature changes than a worm gear clear.

 

Just stating what I see it looks like the coolant is seeping out the hose it looks like the clamp has gone weak. Never liked those clamps I don’t trust them had a few disintegrate on me in the past

I had a few snap on me as I compressed them not fun and kind of a pain to get off at times like you just cant get it to compress to the point you can get the clamp off the hose

 

I think the constant tension clamps are nice but dig into the hose over time and stop being effective. I can either spin the clamp and give it new life? Or if the hose has gotten to soft/rotten...Just buy a new hose and clamp.

 

I cannot for the life of me get the lower hose off the thermostat housing tube! Wow!

Also it's harder than heck to see the weep hole...Wish I would have inspected it when I had the harmonic balancer out of the way.

Edit - I went to O'Reillys to look at a new water pump and pin point the weep hole. The weep hole is on top despite what Chiltons has to say about it. Glad to report mine is bone dry. I drove my truck to get the fluids going and up to operating temp. I think I might have fixed the leak by messing with the lower hose. It is moist up around the bottom of the water pump...Maybe I need to tighten the bolts to torque specs? Hope it's not a bad water pump to block seal...I really don't want to take it all apart for that.

 

Just because the one at O'Reilly is at the top, that doesn't mean yours is. It still sounds like your water pump may be leaking. Can you wobble your fan at all? If you can, your bearings are probably bad.

 

I can CLEARLY see my weep hole on top and the O'Reilly one was identical.

No wiggle/wobble...Solid.

 

Alrighty then.

 

Tom,

Not down playing your help...It's greatly appreciated.

I was sure I knew the weep hole was dry and on top until I looked in the Chiltons. It said: "In most cases you'll need a flashlight to find the hole on the water pump from underneath to check for leaks". As you know the problems with these books is they cover many models with different engines. It also says to check for wobble which I didn’t read earlier so you suggesting it was good advice…Thank you.

I need to keep an eye on things and see if the drip forms around the T-Stat area like before.

 

Yeah, I got out my vise grips which held the clamp open when I removed the old hose.

 

Sorry, I wasn't trying to be a smartass. Obviously, the best way to check it would be with a pressure tester but I'm out of ideas short of that.
