water pump wooos

[woodwardsh3]

Ok hummer h3 I5 gurus please offer your tips or suggestions.
I have replaced my water pump 2 times now and it is leaking again. Not sure exactly where yet .
1st one was a bosh water pump it lasted about a year & 8000 miles when removed it did look like the shaft and seal were leaking.
2ed one was bought from 1aauto 10 year warranty ACdelco now it is leaking again.
When I removed the last one I used the gasket with no silicone on a clean surface and this time I used ARP thread sealant the white past
as the threaded holes go in to the water jacket and I torked them to speck from the forum. the belt tensioner is working there is no weird sound and
it is a very slow leak the one you smell but it's hard to find a drip. well now I can see a drip off the front of the motor on the driver side and it is wet on the front of the motor. I Have worked on cars an trucks an machinery for over 35 years so I should be able to handle this. Though I'm on a bit of medication for chronic back and neck pain from the 5 surgery Ive had over the last 25 years. So I do tend to take a lot longer to do the job and have to double check things as not to forget something.
Thanks for your help

A bad fan clutch or out of balance fan blade will cause premature wear. Fan blade missing any pieces?
Drivers side i would take a good look at the thermostat housing.
They make a dye for coolant systems.Makes it easier to track leaks using ultraviolet light.
Out of control electrolysis could be eating it from the inside out.Never heard about this on the I5 but i have recently seen this on toyotas and dodges

If you think you need a fan blade or new clutch Rockauto is a good source.I'll give you a used fan blade Just pay the shipping.

The fan spins true no missing parts. But when you start the motor when cold even in the summer. The first start of the day, the fan is moving a ton of air and sounds like a semi truck. for a few minutes until it warms up 1 to 3 minutes id guess. it has always don that since I have owned it. bought it at 100000 miles. I thought that was normal. IS IT ?

Is this common that the fan roars on cold start up for 2 to 3 minutes.

I don’t know anywhere specific but check to see if it’s puddled up anywhere causing the “illusion” of a leak. I also recomend some coolant dye, would make it a lot easier

My HUMMER never roars for any longer than about 45 seconds, definitely not 3 minutes.

Getting ready to change the WP on my 2006 as well. Always best to replace the WP and FC at the same time. I am also seeing a very small leak but really smelling the antifreeze. Leak is almost impossible to see because the antifreeze is burning off the hot engine, hence the smell. Good luck with your WP and FC replacement.
