I just installed my rad last night. Heads, cam and headers finally done.
Does anyone suggest using water wetter in the coolant or just coolant.
Also what kind of a setup are you LT1 boys running after the headers, magnaflow will not fit.

Thanks

Fred

I use water wetter in mine and it seems to help, even with the biggest "Griffin Radatior" i could put in there, it still runs hotter than i would like with the a/c on. When you push it a little hard.

Any headers and any given exhaust system should be no problem. It's just a matter of making it hook together. Any exhaust shop worth it's salt should be able to handle it with no problem.

On my 93 I used the Exotic Muscle headers, two feet of extension pipe welded on to a X pipe then into a Corsa exhaust. Of coarse I cut off the resonator from the Corsa system. Sounds bad ***!!! Especially since my cam has a 110 LSA. Fred, you might consider heated O2 sensors.

I'd wait to see if it's needed. My experience is that it works, and works well, but why spend the money if you don't need it.

RACE ON!!!

Plus, you can't use antifreeze with this stuff, can you? I wouldn't want to give up the chemical protections that antifreeze provides in a street car. If it doesn't run cool enough to suit you, I'd solve the problem mechanically.

Yes, it's made to work with anti-freeze and/or water. I have used it for years and it helps, also lubricates your water pump.

Thanks guys, I have to run cats so I'm waiting for the new Magnaflow to come out. It should be out in a month, very short about 3-1/2" diameter and legal in 49 states so it should work up here in Canada. I asked Merle about heated o2's and he said I didn't need them.

Thanks

Fred
