Re: ls radiator in 79 truck
well no my 79 sat for a couple years with the engine out of it. the cheap fine china aluminum $200 radiator I bought when I did the ls swap in the 77 started leaking so I took the radiator out of the 79 and put it in my 77 I had to buy to a cheap radiator because my son sold the orginal 77 one for scrap I have a 6.0 ready to drop in the 79 now but with no radiator I have 3 ls radiators sitting around from other junk so I am gona try to put one of them in I think its gona work been out today foolin with it I think i may be able to make it work .

Re: ls radiator in 79 truck
I used just about everything from the donor 2004 2500hd. Radiator fit great with a few cup style mounts welded into the bottom core support along with 2 nuts welded into the top. Trans lines, and stock cooler fit great as well as stock radiator pipes. No issues with the stock fan, just need to fab up a shroud. I had no original parts worth reusing from my '77 hence using the newer stuff.

Re: ls radiator in 79 truck
most of the parts used to put the in radiator came from junk sitting around that's why I don't throw nuting away

Re: ls radiator in 79 truck
hello all. if I remember correctly, how will you fill the ls radiator? it doesn't have a vent cap/neck. are you gonna fab up a way to use the ls overflow canister? also another thing to remember is to burp or extract all the air out of the cooling system. some of the forum users have had complaints about air pockets and cooling problems. 4x4k30 & cdub2010 you guys are smart for using the ls stuff. GM has a lot of R&D behind the LS. Good luck.

Re: ls radiator in 79 truck
Using the stock 2005 coolant tank just like gm did. Lots of smart people working there, so no need to reinvent things. Just need to mount it up to the pass side inner fender. Ill post some pictures if I can get some time in the shop soon.
