Water Pump Change-out

[Dennis]

Howdy fellow Hummer nuts..

I'm getting ready to change out My 06 H3's Water-pump (it's making a noise, or it's the Fan clutch)...so while I'm doing that, I will also change out the Fan Clutch..All with Delco(GM) parts...I bought a couple of NEW specialty tools to make the job easier; the 36MM Fan clutch wrench and the Water-pump Pulley holder spanner wrench..

If anyone is interested..I will post some start to finish pictures with a narrative of the project...Also I will be selling the tools after I'm done at a USED price..PM me if you want the tools..I'll post pictures later in the "swap meet topic" of the tools, once I'm done..so you will be able to see if any, if there is any wear and tear..(probably won't be any at all)

Yes, looking forward to how-to pics. Mine was replaced by the dealer but I'm sure I'll burn this one out at some point.

On original one at 103k miles so I'm sure ill need mine changed out soon so I would love to see a write up.

 

[Happy Hummer]

Agreed... Gf's H3 is at almost 90K so probably gonna need some help eventually.

Hey...at 65,000 miles:

I tackled the job today..took me 4 hours to Change oil, Change anti-freeze, Change Water Pump, and change Fan Clutch..

Beside the Tensioner Pry Bar (loaned from Auto Zone), you'll need these two tools (Now for sale---$30.00 + S/H)

Oil was Castrol Edge, filter was a Royal Purple brand.

Anti-feeze was Prestone (Dexcool) 50/50 prediluted.


Fan Clutch was a OEM (Delco)


Water Pump was a OEM (Delco)


The pump must of started to leak not too long ago, cuz this was all that was evident of impending failure..Fan Clutch was also making a noise, so it got replaced while I was there...

You have to remove the upper Radiator hose to get the fan shroud out..But it was overall a very easy repair....I would advise if you are hardcore wheeler to clean the fan real good too, while you have it apart, dirt will throw it out of balance...Also be very careful not to over torque the waterpump bolts..



Sorry, I didn't take pictures of the whole job..I was multi-tasking with the oil change and stuff, so I didn't organize the project.

i might have to change my pump out, so is an oil changed required when you do this? i just changed the oil.

 

[MaxPF]

No oil change is needed when changing a water pump. I'm guessing Dennis changed his simply because it was due, and he was already dirty

One good trick for those without the fan clutch tool.... One good trigger pull on an air chisel to the fan clutch nut will break it loose instantly. Saves a lot of hair pulling. Which as a 40 year old, balding male, I cannot afford!

Ok well if theres a special tool involved that the stealership would have, that gives me a good excuse to just outsource it to the stealership. I have finals for school coming up, so i have no time to tackle this myself

I would ask jerry how much they would charge for labor. there are sites that have oem parts cheaper...OEM pump at the dealer would be around 170, online you can get it for 110 and use a coupon code and get some more money off. If you need gaskets and pulleys also you will probably spent 250 in parts at the dealer vs. 150 online shipped.
