Thread: Radiator Upgrade Question 97-03 GP

i just changed mine, i was only able to find 5/8 and 1 inch cores listed. 1 inch should be more then enough.

getting hard to find the 1.25"

i had a hard time finding the 1 3/8ths "true" LQ1 radiator, an old delphi from back in 04.
found plenty of 1.25" till we finally found a fatty through my buddy at grossinger chevy.

if your lucky youll find an LQ1 in the junkyard with the 1.25" that has been replaced.

1.25" cools 608 fwhp just fine. the 1" is all youll need if your looking to get up and running

I got mine from rock auto. Look under 95 monte Carlo 3.4 for spectra part#cu1518 looks like $102. Ran it 2 years now with out a problem. Stock lower hose works just have to cut it shorter so it won't hit the ac compressor.

The ones from car parts.com are 1" in the box labeled 1.25 as well.

Now ill try and order one with that 1518 number and see.

Edit: cu1518 is a 1" core in the box from spectra, I got someone to open a box.

432694 doesn't seem to be a part number nothing came up when doing a search.
This is the radiator that everyone says to use, there is a thread on here with instructions and such as to what all you need to run it

Hmm. Someone said something one time about a 4.3 S-10 rad fitting. Supposedly that was what the zzp radiator was, but they don't even look the same so idk.
I would just pick one of the 1inch ones the stock size is 7/8 so even that extra 1/8 of an inch is better.

You gotta search just a little harder, there are larger core Rad's still out there... Can't vouche for the brand, but if you want more cooling core size, its available...
