We dunno.. what in the world are you working on?Did I order the right radiator?
I have a 1999 GMC C1500, kind of an oddball year, I know. May be why.We dunno.. what in the world are you working on?
That's the heater core return line connection.. on SOME years of GMT400 trucks. Some years return to the water pump instead. So if yours didn't originally connect there, that's why there's a rubber cap provided..

1999 "classic" and yes order for 1998 as it's less confusing to the parts people/websites.That would have been good to know on the first post. If its a GMT400 body then it was built in 1998 and just carried over to 1999. I'd bet you got the wrong radiator, check if its the same part number for a 1998. In the future, order parts for a 1998 instead.
Thanks for the advice man! It's my first car so I am still learning about certain tiny details and how to order correct parts.1999 "classic" and yes order for 1998 as it's less confusing to the parts people/websites.
I wouldn't figure it's the wrong radiator, or it simply wouldn't fit the core support. Big difference between a GMT400 and a GMT800.
Most of the GMT400 aftermarket radiators I've seen have that connection. Many year models of GMT400's do use it for the heater core return line.
And, good advice from east302 on replacing the cap with a silicone piece. I've seen those rubber caps fail, even in less demanding environments than an engine compartment.

No worries. There's not a lot of 1999 "classic" models out there - and that's what yours would generally be referred to if it's still the 1988-1998 body style, a.k.a. "GMT400" trucks that this site is focused on. Since 1999 officially was the next generation of trucks, GMT800's, which ran from 1999-2006 (and 2007 "classic"), when you shop parts for a 1999, it's easy to find the wrong parts for yours. That's why picking 1998 makes that far less of a problem.Thanks for the advice man! It's my first car so I am still learning about certain tiny details and how to order correct parts.
I had a similar one on a suburban a few years back and that plug would fail for some reason and radiator fluid would spill out. I started to carry a extra plug in my glovebox.Did I order the right radiator? I swear to god I cannot figure out what this hose connection is for!
