Is there a part number for this?
 

Okay its been leaking water from here and well Ive changed the gasket tons of times and still wont fix it. Well after trying to take it off...it finally broke...which is good cause I was planning to replace it. But is there a part number for this or will I just have to get a used one at the junkyard?

yeah i got one from advance auto where i work i forgot the part number but go to one and have em look it up for you,.

lmao thats what i took off this weekend thinking my thermostat was in there and 2 hrs later found out it wasnt there lol but yeah i need to replace mine too

what is that???

okay I got it and now its not leaking from there....but its leaking now from that metal small pipe that connects into it...I cant find the right gasket for it

Man that thing was obnoxious, kinda cool how the plastic flakes off eh?. I changed mine, leaked again and i sealed it tight, but kept on leaking, i just took it into GM lol $400 later......

Me and my pop fixed with with a o ring we got in a "HELP!" assortment.

Water outlet housing. Factory number 24575259

If you go aftermarket you need to cut the groove a bit deeper and use a thicker gasket.
