3.4 Liter GM 3400 Engine Replacement / Swap 1999 Alero / Grand Am 4 Door

Bought this 1999 Oldsmobile Alero For $800 with a known bad motor. Engine was shot, knocked and burned antifreeze due to a bad head & intake gasket. So, I found another 3400 from a wrecked Grand Am. Was smoked in the back. Got the replacement engine for $500 (ouch). Put on a new intake manifold gasket on the replacement motor as well. Pulled out the old engine and replaced it with the new one. Runs like a champ now! These engines are good, if the intake manifold gasket has been replaced. Put lots of silicone to each edge of the gasket. Sealed up great! No smoking and no leaks like these are natorious for.

Green antifreeze? has that been converted from Dexcool

[Vacationtime247]

@homes24 Don't like the Dexcool, it's more expensive and I don't think it works as well. Good ol' antifreeze works for me = D

hey Vacationtime, when you said you were going to get a 'connector' to join the fuel lines, what exactly were you referring to? I am taking out my 3.4 right now and I wanted to know if I should go with just some hose and clamps, or maybe you know of something else?????????????????????

Thanks and great video learned a lot .

@shawnwhite00 I cut the rubber line for the fuel. Put in a short piece of steel line that was flared out on both ends. Double clamped it at both sides for both the in line and the return line for the fuel. Those quick disconnects suck! There was no way mine was coming loose.

@homes24 Dexcool ruins head gaskets and casues early deaths in engines
