I just recently had a T fitting break on my 04 ls1 gto. For reference this t fitting sits right above the ac compressor has 3 lines that connect to I’m assuming the water pump, heater core, and the there’s the 3rd lower hose that runs under the motor. I was told that hose connects to the stock oil cooler and that instead of the just replacing the T fitting, I should run a straight hose (heater core-water pump) and bypass the oil cooler because at 150k miles the oil cooler could start mixing oil and coolant. If it’s true, how would I do that, and should I even do it to begin with? ]]> Pontiac GTO 2004-2006 Firebird Factor https://ls1tech.com/forums/pontiac-gto-2004-2006/1984919-oil-cooler-issues.html https://ls1tech.com/forums/pontiac-gto-2004-2006/1984742-new-me-04-a.html Sun, 03 May 2026 20:22:39 GMT Did a little cleanup on the '04 I picked up yesterday. Came out pretty good. Not sure where I'm going to go with this one but we'll see where the road takes us lol. It is VERY comfy.

'04 - Auto
142k
Headers, SLP Exhaust, Cam (of not quite known spec), and Dyno tuned by Speed Inc. Heads were done by a shop in Rockford I found a receipt for, so I'm going to see Monday if they can give me some more info. Car really really runs nice. Plus the AC is cold! Has a goofy Kenwood double din that's going in the trash eventually, otherwise pretty untouched. New 235 and 245 series BFGs.

Next up will probably be some headlight resto and caliper painting.

Today I steamed the interior, and used the carpet extractor. Seats are typical GTO and have been repaired okay. Swapped the interior lights to LED, along with the plate lights. Gave the engine a scrub down with 3D Super Degreaser, and P&S Carpet cleaner on the inside. Used Meguairs APC on all the hard surfaces with the steamer, and treated everything with 3D Leather/Vinyl. Smells better!

Outside got a good wash with the foam cannon, and a quick Griots Ceramic Spray application for now. Paint is really nice, need to do some compound work on the hood for swirls, and where the front plate mount was.
