Toyota Prius Engine Replacement Swap - Second Generation 1.5L (2004 - 2009)

[@stealthhelp]

Always a good feeling hearing that its a good motor and everything is smooth when you turn it on LOL Always stressful when using a used engine/transmission.

[@peterad1529]

Nice video mine has 275k miles no holes in the block but using oil like crazy now . I plan to swap it out for a lower mileage unit. And for the nay sayers or people who ask if it’s worth it, yes it’s much cheaper than a new car. As much as I’d like a new car it’s just too expensive back even used cars are too expensive for me at this time. But I’ll also be doing the swap myself so someone who doesn’t know cars would have to calculate that into their justification 😊

[@stealthhelp]

Mine has 326k and purrs. So eager to see how long it'll last me lol

[@vtecbrown]

Great work. I'm doing one on a 2006 right now. Only had 167k miles when it blew but the previous owner let a head gasket go way too long..

[@happywrenching]

Those pesky head gaskets! Just did a swap on a 2013 Prius with a bad head gasket. Should have that video up soon.

[@nwbee4692]

20:09 is the wiring harness being fed from inside the car? and why the need to make your own pulley holder?

[@Sic3r]

Mechanic asmr 😌

[@ridenda67camaro]

Great video!

[@LuisAguilar-vy4uy]

Good video brother 👍

[@thewatchman3918]

The motors seem to fail because people don't keep an eye on their engine oil level 🎚️💥

[@hansgroenewegen6910]

Great video! Thanks. Question: why did you remove the complete cable harnas? Is that necessary?

[@charleshorseman55]

You have to remove it entirely from the engine AND from the firewall. It stays connected to fuse box and flips over out of the way.

[@gerardodiazmoran6824]

21:47 I expected to hear the start of the prius, but another car interrupts it.

[@local701]

Yes it did. Sounds like a GM Ecotec, chime and all.

[@B0ND0N1777]

I was looking to see if someone commented about the engine start. Hybrids don't crank like that, at least my Prius hasn't ever.

[@cesarnunez891]

Where did you mount the engine hoist on diver side? It’s that the PCV valve? Can it handle that much weight?

[@charleshorseman55]

It's possible to remove the ice without taking off the pulleys and water pump, but it's quite obvious putting the new one in will require it unless you've got 6 hands on it 😅

[@riceburner4747]

Is it possible to drop a 1.8L?

[@haydeemarti4168]

After installation we needed reprogramming? Computer?

[@happywrenching]

Nope, nothing else needed

[@haydeemarti4168]

Thanks ,because a mechanic installed used engine and chargerme for programming with special computer

[@khalid109q]

Well done.

[@pfoxhound]

6 hours? Looks so easy!

[@charleshorseman55]

Not the easiest. Keep the bolts with the parts or put them back in their threads. Take pictures. The wires weave over and under water lines

[@bryanji8507]

How much does the labor cost?

[@midwestcommunitynews3847]

Was the engine used a jdm version or american engine ?

[@lani6575]

Can you list the tools used? Trying to do it myself for the first time 🙃

[@arturoguevara8525]

[@rhythmtone]

Nicely done, I only want to know one thing, where did you get those gloves? Haha

[@happywrenching]

Lol, I'm always on the look out for the perfect gloves. I think I got these from autozone at some point. I recently tried a pair of astro-grip gloves made by SAS and was blown away by how good they were.

[@remi2317]

Did you have to flash the ecm?

[@mouawangtzullc6316]

I need you to replace my prius, do u live in MN

[@wpcote108]

Did you have to remove the water pump off the front of the engine?

[@happywrenching]

Not on this generation Prius. I only removed the crank pulley on this one. The 2010+ generation I had to remove the electric water pump.

[@Noslime]

Was the vehicle even worth the trouble?

[@happywrenching]

It’s different for everyone - in this case, $500 for a replacement engine plus a crazy discount on labor :) and the person had a cheap fuel efficient first beater car.

[@redamohamed4759]

Hi happywrenchy, Great job, I am doing swap atm and following your video and stuck to separate engine from the gear. When I left the engine it separates from the gear below more than top and I could not take it out completely. Any advice please ? Thanks

[@happywrenching]

Make sure you remove the crankshaft pulley to get more clearance. More space below than the top means the engine is not balanced properly on your lift. Most engine lifts come with a load leveler bar that is used to shift the weight of the engine. As an alternative, you can use another jack under the engine to balance it from the bottom. Good luck

[@redamohamed4759]

@@happywrenchingthanks a lot for your reply. Any advice how easily to remove the pulley please ? Do I need to prey the engine? Is there any specific sites for preying? Thanks

[@happywrenching]

@@redamohamed4759 Removing pulley easily is done using an impact wrench. If you don't have an impact you need to hold the crankshaft in place. You can wedge something between the crankshaft and the block or wedge something in the flywheel to keep it from spinning when loosing the crankshaft pulley bolt. You may need to pry the engine from the transmission - that is assuming you have room for the engine to slide to the passenger side and you have all of the bolts out.

[@redamohamed4759]

@@happywrenching thanks a lot for your advice ( levelling the engine). Luckily I have tried to take the engine without removing the pulley. Any advice please reg installing the new one ?? Thanks

[@happywrenching]

@@redamohamed4759 only thing i can recommend is to go slow and check around the engine often as you lower it so you don’t damage anything.

[@HassanHansenTV]

Question please replacing the engine is new ???? Or used !!

[@happywrenching]

Not sure what you are asking - I put in a used engine.

[@HassanHansenTV]

@@happywrenching I meant saying putting new engine zero mileage is there a possibility!

[@supremeonly]

Good morning I swap my engine but I'm not getting heat. any help will be appreciated

[@happywrenching]

Most likely air trapped in the coolant system. There are KZbin videos out there on how to burp the heater core on the second gen prius.

[@JOSERAMIREZ-hi9ri]

How did you remove flex plate from transmission?

[@happywrenching]

It's not a traditional flexplate so there is nothing to remove. Much like a manual transmission, the "flexplate" just slides on to the transmission output shaft.

[@scooterwoodley195]

Nice job! How much was the donor engine?

[@happywrenching]

Keep in mind that I did this swap 2 years ago so not sure of today's prices but at that time, the donor engine with 166k miles on it was right around $500 after taxes and fees. Thanks for stopping by!

[@colinerdman]

Does the ECU need to be swapped as well?

[@happywrenching]

Nope, engine only

[@jaybailey990]

What do you charge us to do this?

[@happywrenching]

I charged $800 for the last one I did but I'm not a shop mechanic and do this on the side.

[@janvanderlinde3039]

where did you put the start motor ??? never hear my start motor :( ( it has non ) - it,s a hybride you now

[@azemhanna4096]

I need it for my 2012 prius ..anyone willing to do it for me?

[@werdy]

Where are you located?
