Question Cracked manifold

Hey folks. Have a 2006 Grand Prix GXP, and it looks suspiciously as if I have a cracked water manifold. Aside from the nearly $500 it will cost to purchase a new one, how much pain am I looking at to replace the cracked manifold? Is this something that might better be done by a professional? I have all the tools needed, but I'm admittedly getting a bit on in years and am finding that my ability and willingness to crawl under, over and around a car is decidedly less than when I was in my 20's, 30's or even 40's.

You can pick them up cheaper than that x11nut has a few I think he would probably sell u one. And it's not bad just a good set of gear wrenches could have it done in less 3 hrs

Yeah, I could, but it's going to be a couple of days. Light isn't worth a crap by the time I get home from work, so it's a Saturday kind of thing. The way the car sits in the garage, the hood blocks the overhead light...

I was just curious as to what manifold you were referring to, intake? Those should be able to be found reasonable but I didn't think they have water jackets in them so not sure what you need to replace. I hear yea about working on cars as we are getting older , I cant do nearly what I used to and these cars are a pain to work on as everything is so packed tight. Someone in the know will hopefully chime in

He said the water pump manifold. But I'm curious as to how that would've been cracked. Unless it got hit with something maybe or not enough Dex-Cool mix in with the water and it got too cold and froze it.

Oddly enough the mixture tests at -35F, so I'm puzzled as to how it got cracked myself!

Pretty sure it's just your water pump going out which would be a slow seepage at first. Unless you can visually see a Crack formation

I thought it was the water pump he was referring to, just never heard it called a water manifold. If something is cracked as he suggested, would the whole assembly bracket system need replacing?

This?

Yes that is the water pump manifold. If it is cracked on the outside he could try JB Welding it before taking it off.
