How do you replace radiator on 2005 chev impala?

Answer 1

It's a bit involved but definitely a DIY project. You'll save $$ and with that money you really should get a Haynes manual. Heck, even a library has it or the Chilton's. Basically, you need to get the battery out and the air cleaner box - at least the part that's in the way. The fans/shroud comes out first. There was a bolt on each side and two on top. Those two on top go into clips which will likely drop down out of place once you remove the bolt/bracket and it's difficult, if not impossible, to get both into place again when you put the shroud back on. I smeared some JB Weld along the bottom of each clip to hold it there permanently. Wait till the mixture gets a little tacky first before applying. Also, there's a plastic push pin holding the shroud to the radiator on the bottom on the driver's side (look through one of the holes down there). It's easy to get out; use a small needle nose vise grips to push the pin back in - it really can be done. Pull clip off that is in center of shroud. Disconnect the two plugs going to the fan motors. Those plastic clamps holding the cable in place can remain. When you pull the shroud out, just rest it on the right side of the engine, there's enough cable slack to do that. Transmission cooler lines - pull back the plastic piece first. Then you'll see a wire clip inserted part way around the quick-connect. Pry that out. Try not to break it, you may need them. My new radiator had new ones installed even though Delphi said they weren't included. I think now you can just lift up the radiator. Take the rubber mounts off the bottom to reuse.
