About to remove motor for rebuild . Can motor be taken out by itself or do you take trans out with it ? Also how about engine wiring harness where does that disconnect ?

 

Search for this, there has to be threads about this already.

 

Tranny does not need to come out.

Since you're doing a rebuild you could have the heads and crossover pipe removed before removing the engine. Removing the heads and crossover pipe will let you disconnect the engine from the tranny easily. You've a v6 yes? then that'll apply. You'll see that the top two tranny bolts are a pain in the butt. You'll need a few wobble extensions to get it out otherwise, when you bolt it back up you'll need those wobbles. I myself kinda just reached in there and turned the bolts a couple millimeters at a time though. ha

ECU is on the passenger kick panel. disconnect it all there. The wire harness is wrapped all around the engine compartment and the transmission.

There are three on the transmission if i remember correctly. The o2 sensor on the left. one on top and another on the right. Then you have the harness wrapped around the bay going to the coil and air cleaner. There are some random ground wires on the left side as well. Two at most, i'm sure it's just one though.

 

thank you it does not look like an easy job. I have searched and could not find anything helpful

 

Don't forget to disconnect the fuel line....they are $50 from the dealer. Don't ask how I know!

 

Ah yes, the fuel line...the guy i got my engine from decided to cut it cause he was too lazy to look how to remove it.

You can find it in the right front wheel well. It'll be a shiny goldish long bolt. Two 14 wrenchs will do the trick.

The vacuum lines on the right side of the engine bay, or left looking back, can just be pulled out. They're not too hard to put back in the right spot. Take photos and mark em though.

 

And yes, it's no easy job. THis engine is a SERIOUS pain in the butt. However, if this is a vehicle you plan on keeping for awhile it'll be great to do. You can learn the ins and outs and every job after this will be a cinch!

 

if it is the 3vze like I have, in my opinion it is easier to pull engine and transmission saves you the hassle of removing transmission bolts that are almost impossible to get to

 

it is a 3vze . have intake off, .p/s off,a/c compressor loose from engine. still have to find where to disconnect gas line ,clutch line, and wires. not so quick though just got out of open heart surgery and son has taken over job we just use my eyes.

 

Well good luck and keep us updated!

 

make darn sure when you pull the wires out you DO NOT skin them... you'll be spending your time finding a problem you'll never find if you do...




I don't understand this one bit...

That is NOT a good way to get an engine out. That is taking it out piece by piece.

The best way I know how is to lower the tranny x member, then with the jack out of the way you can reach up from behind with long extensions and remove the bell housing bolts. Then put the tranny back up.

Then take the 3 exhaust flange bolts off and you're good to go.

Providing this isn't an Automatic.

 

engine out waiting for son to get it together

 

It worked out for me on a few levels. Yeah, kinda stupid and a long process, but what i was doing at the time was trying to figure out what was causing the engine to not start. In the end i had it all apart so i decided to continue till i only had a block! I don't think i could've figured out how to get to anything otherwise myself, such as the mounts or figuring out what connected to what. Disassembling piece by piece helped me figure all the odds and ends. Maybe not the best idea, but it worked out in the end. ha

The thing with the transmission, wouldn't you have to disconnect the drive shafts? I was considering that when i was bolting it back on but i was too scared to mess with that thing.

Also, i didn't find removing the wire harness to be too dangerous. I'd imagine skinning it would be a problem though.

 

Awesome, any photos?

 

I will ask my son to post some he has been taking pics of wires and hoses I know. WE started project by welding new pieces in rear wheelwells then I went in hospital for bypass surgery It is all his project now I will watch and pay (only thing to do for fun, watch it all happen as long as money keeps us going)

 

I'm also in the process of pulling this engine out of a 93 4wd p/u, I need to know how you got the engine out without removing the trans, did you have to remove the clutch slave? and do you have to unbolt the clutch and flywheel or do they come out as one unit attached to the engine? I've been working on getting the engine out for about a week and a half, taking my time to mark eveything. I really don't want to pull the engine and trans apart and something fly apart that I didn't see how it was put together. So any help at all would greatly be appreciated

 

Clutch slave...hmmm i took mine off for some silly reason. I think you just have to move it outta the way as it's bolted to the block. Yeah, pain in the butt.

Don't worry about the clutch and flywheel those come out together.

 

thanks alot, i've already gotten all of the bolts out and the starter is such a pain, glad i've got to replace it to be honest. engine mounts are unbolted as well, is there any reason to unbolt the drive shaft and move the trans, or cant i just pull the engine forward to get it off of the trans?

 

You might wanna try what the other guy said about lowering the transmission. I'd imagine that'd require unbolting the drive shafts. (I could never get my front shaft seperated!)

Those transmission to engine bolts are a pain in the ass, oh and that starter as well. Holy crap what was Toyota thinking.

 

you can remove the engine as a single unit. You will have trouble getting to the top tranny bolts but if you loosen the crossover pipe nuts then it will move and you can get to them. I removed the engine from mine with this method and were it was a pain it was doable. You will have to remove all intake components first though.

once you have removed all tranny bolts jack the front of the tranny up to give you some angle for removal and also when you re-install it.
