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




What do you think about this video?

Davie Jones: The only reason head gaskets go bad are either too much pressure in the head by over turbo charge or a blower or someone let a antifreeze leak prove fatal when they instead of replacing it with the good stuff put in good antifreeze coolant and regular tap water! Tap water has calcium and rust and all kinds of bad stuff in it and what happens is that the calcium collects around the shaft of the thermostat during the summer and when the first hit of cold weather come's around it seizes up and won't open when the engine get's hot and over pressurizes the coolant ports and it finds the weak area which is the head gasket and it blows a hole between the cylinder and the coolant ports which don't ruin the engine but makes you have a job changing the head gasket. That is if it don't crack the block! The only way to find that out is changing the head gasket and doing a pressure test on each cylinder! Tap water is not our friend! Use distilled water only in your radiators! And never trust premixed coolant ever! I never use it! You can't trust companies to be honest about using distilled water in their premixed antifreeze! 

Ricky Temples: Most shops don't want to work on my car, especially doing my new exhaust, they all want to claim that it's $2000 to do, and they bullcrap me everytime. I just need someone in Georgia to remove both manifolds and either replace them with oem product or pacesetter headers. 

Miguel Barriga: 3.1 and 3.4 are rare here in Coachella valley u just see Honda's and Toyota's 

3waymore: Please tell me two things. 1) how did you get the lower engine to tranny bolt out on the firewall side? 2) how did you get to the exhaust bolts. PLEASE help soon

Byron Da Shirtmaker: How much do u charge to swap out a engine? 

Morgan Freeman: bra's cause rust and paint fading

Vacationtime247: @curley920 Lawn will get mowed, eventually. VT247

dkhill27: I have a 00 grand am gt and it blew the lower intake manifold gasket at 149k miles. It was pretty easy to do. Put a fle-pro gasket on it and some silicone on it. Im at 159k and no problems. My question is how long did it take you to swap motors? And would you know how long it would take to do a tranny swap? Starting to slip under hard acceleration only. Nice video btw thanks

Joey Nash: how did u do ur cold air intake???

bteeuwen: this is the 24v 3.4L right? haven't heard the greatest thing about them but there is a lot on the road though.

brad ornat: nice work

ImpressingtheCritic: Hey Lee, are you by any chance, a Jack Ass? Or are you just short with a Napoleon Complex?

homes24: Green antifreeze? has that been converted from Dexcool?

Vacationtime247: @forestcamper Guess that all depends on where you get the new engine from. You might get everything if you get it from a salvage yard. If you get a new engine from Autozone or otherwise you might just get the block and heads. VT247

Vacationtime247: @MrRichierich1990 If your car is bubbling out violently, like you hear a pshhh with steam coming out or the overflow tank is bouncing and gurgling there is a problem. Two main culprits would be the thermostat stuck closed or the water pump isn't pumping water through the sytem. What does the temp gauge read? If it's reading high, check the pump or thermostat. VT247

curley920: Did the lawn get done?

Vacationtime247: I only unhooked what was necessary to get the engine out. The old engine that was in there had a knock. Got another engine but things had been taken off or were no good. So I combined what I could to make one good engine. When I say I had to 'get' something it usually meant it was swapped from the old engine. Gaskets and a few parts were however bought new. True, there is a bolt that goes the other way holding on the transmission. This method works for me. VT247

Forest Camper: @Vacationtime247 Thanks for responding, I recently bought a lemon and the previous owner is being extremely uncooperative. I'm evaluating my options for damage control.

Vacationtime247: @jfletcherwilliams If it's not 12 volts at the brake light switch, follow the wiring diagram back. Or, just wire in a 12 volt power source. Make sure too that you have ground! VT247

Mike Allmon: how would that be considered a cold air intake when you are making it breathe hot under hood air like that?

Vacationtime247: @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. VT247

Vacationtime247: Not exactly. All that work to make some $. Just so happens that it was an Alero. I'll buy any car if it's cheap and can make some money on. Today's project, breath new life into a '99 Durango I got for $500. VT247

81TurboTA: Hey I need HELP................... I am going to pull the engine from a 2000 Grand Am GT to put in a 2001 Grand Am GT both are a 3400s' Did you pull from top or bottom?

Vacationtime247: There are bolts holding on the transmission that you can easily see from the front of the car. There are one or two (can't remember exactly now) that go the opposite direction in the back. You'll need a long extension to take 'em out. Also, don't forget the torque converter bolts as well. The rest is pretty straight forward. VT247

Casey Rodriguez: After market intakes lose power. They sound good, but lose power. It took a cold air intake extended 2 ft in front of the car with 70mph winds to see gains otherwise it's just a loss of power.

Adriel Lozano: Heyy anyone who knows how to remove the engine on a grand am email me plss alozano9811@gmail.com

crosstimbers2: Can't you make your videos without the lawn mower?

Vacationtime247: Way to much work. It can be done, but you're going to have an enormous amount of time and money into a project like that. Much simpler to just get a Pontiac GTP or Buick Regal GS. VT247

Vacationtime247: If it's coming out the top, then all those things you mentioned earlier don't need removed. Be careful of the radiator not to knock a hole in it by accident. From what you're saying, it should be ready to pull by hooking up the chains and lift. You going to put the heads on after dropping the block back in? VT247

onenikkione: wish i had a neighbor that can swap engines (and more). a 1999 anycar where i live would be all rust, not just on the hood. : (

Robert Shaw Jr.: How long would you say it would take to take the 3.4 oft and install the new one. I have a grand pretty much the same

John1013: Did you have to reprogram the ECM (engine's computer)?

Vacationtime247: @riviera97sc For extra insurance, I added a layer of silicone to both sides of the lower intake manifold gasket set. Wanted to make sure it would never develop the leak around the water jackets. : ) No leaks, it's been 6 months and still drives great! VT247

Xavier Holland: Lol random duck sexy stare. :P Dude, nice swap. I too have the v6. Plan to keep it for as long as it will move, then pull a block, and move it some more.

Nick Ritter: how did you seperate the transmission from the engine im dong the same thing right not and i cant find the access plate like most cars have can you please respond ? thanks

midgetmayo: @Vacationtime247 Dexcool eats the gaskets anyway..

jfletcherwilliams: I have a 99 Alero w/3400 too. What is the purpose of modding the air intake? And when looking in salvage yards for an engine replacement, how do you know you aren't getting one that's also got a bad intake and/or head gasket? Thirdly, do you have any knowledge about why brake lights won't work even after bulb change, fuse, and brake pedal switch change?

Vacationtime247: You can do this swap in less than a day. If you stay at it and 2 if you take your time. This is if you already have everything you need to do the swap. It's really pretty easy and straight forward. VT247

John Doe: @dillonmuhman a GTP L67 motor would have made that Alero one VERY unsuspecting sleeper........

eddie davis: Is the 3.1 and the 3.4 capable for engine swap

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 VT247

Mike Thexton: Hey, chiltons says to remove these before removing the engine Stabilizer shaft links from the lower control arms Tie rod ends from the steering knuckles Lower ball joints from the steering knuckles Cooler lines and bracket from the transaxle Is that necessary, or can I skip these steps?

Robert Shaw Jr.: @Robertksinmi1992 Grand am

81TurboTA: Did you remove the starter to access the flywheel? And did you manually turn the engine to get to the bolts?

Casey Rodriguez: Btw dexcool lubricates gaskets. The gaskets would go bad before you saw any damage from dexcool, it's the combination of dexcool and green anti freeze that can be harmful.

Vacationtime247: Swapping from a 3.1 to 3.4 can be done, but it's not a direct bolt in. Several of the sensors have different connectors, making the computer work with the different engine and swapping out motor mounts. It's possible, but I'd not want to do it. VT247

Bobby Barger: For anyone who is curious, Fel-Pro offers an updated gasket that is made of metal and will not fail. I'm talking about the lower intake manifold gaskets. The part number is MS98003T

Vacationtime247: You can take out the starter and get to the flywheel bolts I believe. Also, to get to the flywheel bolts, you can turn the engine over with the large crankshaft bolt in the center of the harmonic balancer. VT247

Timmaculate83: Great job hope you make good money for it.I know how it is getting burnt out on flipping these cars but what choice is there but to keep going.

Vacationtime247: I'll bet the whole front subframe comes out in their instructions. In some applications this is the best way to do it. Drop the subframe, lift the body and you're at the motor. From there it's just removing the engine / trans bolts, motor mounts, & torque converter bolts. But yes, all those things mentioned need removed before dropping the cradle. VT247
