Ok so I noticed that my thermostat housing was leaking and I know I needed to replace it. I went to my local chevy dealer and they told me the ac delco replacement part has been discontinued. They reccommended going to local parts store and buy a thermostat housing. I just dont want to buy a part that is not going to last or suck. What do you guys suggest? Brand wise?

 

get one for a newer 3800 like a buick

 

That could work. You know for what years

 

heres a list of cars that had the 3800 95-03...

Buick Le Sabre
Buick Park Avenue
Buick Regal LS
Buick Riviera
Chevrolet Camaro
Chevrolet Impala
Chevrolet Lumina LTZ
Chevrolet Monte Carlo (Z34, LT, SS)
Holden Commodore (VS, VT, VX, VY)
Holden Caprice (VS, WH, WK)
Holden Ute (VU, VY)
Oldsmobile Eighty-Eight
Oldsmobile Intrigue
Oldsmobile LSS
Oldsmobile Ninety-Eight
Oldsmobile Regency
Pontiac Bonneville
Pontiac Firebird
Pontiac Grand Prix


i dont know if the series III 3800 has the same housing but heres where you can find them

2004–2008 Pontiac Grand Prix
2005–2009 Buick LaCrosse
2006–2008 Buick Lucerne

 

So basic, I went to the dealer and asked them if they had one from another car like you suggested but ac delco discontinued them on all 3800 series 2. And the new 3800 engines have different design so they wouldn't work. I think I will go to a junk yard and see if they will give one to me. Otherwise it's off to the aftermarket parts
