Will a radiator from a 2010 impala fit with a 2006 impala ltz

I doubt it but if you shop on line for both see if the same part comes up . Radiators aren't something you want to re use . They'll soon have the same problem as the old . What problem are you having ?

Tbe plastic round tip that comes off of the top passenger side that the hose connects to has broke off. Other than that the radiator is fine. I thought about trying to fabricate one but im afraid with the amount of pressure that travels through there anything i might plastic weld to it would soon break apart

On a side note while researching this for hours before, just about every transmission available for purchase would encompass 2006-2011 impala.... I have a 2010 that i got for $100 that was missing the front clip snd have used it as a parts car for my 2096 ltz on several items, but this one im just not sure about. And i cant get a clear diagram for transmission lines that runs with it on both cars for comparison on whether it would line up or not

What engine does the LTZ have? Radiators are usually engine dependent. If you have the 5.3L, then the radiator from the 2010 has a 3.9L engine, so they are not the same. Pick up a used OE radiator from your autocrats store or online vendor like rock auto. $150. I too would not trust JB weld for any length of time.

I've seen many radiators with the glob of JB on them as a repair , Don't know how long it lasts but they always fail . In my area salvage yards charge top dollar so you may as well buy new .

Thank you all so much for your replies. You probably saved me my time, money, and a bigger headache than the one I already had. On a side note my 2006 LTZ Impala is a 3.9L as is the 2010, but I went with just ordering one. Hated to at Christmas and what not but a vehicle is a necessity. I'll have to admit if it were summertime and not into winter I would have prob tried the switch, but can't chance it in the cold. Thanks again guys for your time and advice.
