The AutoZone part number for a lower radiator hose is: M-1068 or 62120. Those are the 2 numbers on the hose. This hose will work if you are NOT using a body lift.

You have to cut a little off the hose. I'll get some picture of where to make the cut.

Thanks

I just spent about 2 hours downloading and printing off of techinfo.toyota.com. I have about 100 pages of info. Hopefully I won't need to much more. Anything specific that I should get while I still have access to the site? I downloaded all I thought I needed, but there is so much on there I'm sure I missed some stuff.

Parts are all ordered. Going to pick up my flywheel right now. Gonna start prepping the 3.4L on Wednsday.

Here's the tachometer mod that needs to be done to make your tach work with the 3.4.

That's the back of a tachometer. Just solder a 10K resister on the 2 points you see there.

Yeah, that's the back of it. You'll need to disassemble your dash, starting from your glovebox, to the key trim and dash trim. Pull your instrument cluster out and remove the gauges from the front of the panel. Remove the screws holding your tach in from the front and carefully remove it from the white housing. Takes about half an hour to 45 minutes or so.

You're welcome. When I pulled mine, I thought it was the back of the instrument cluster. I wondered why it didn't look like the pic. The I realized you had to pull the tach out of the front, solder the 10k resistor (go to Radio Shack) across the two terminals, then pop it all back in.

Not sure what it will read if you run the 3.0 with it, if you're going to do it before you start your 3.4 swap.

Thanks a lot!

Ok here we go....I did just a few things on the motor. I pulled the automatic flywheel pulled some old cut hoses and attempted to put it up on the engine stand but need to buy the correct bolts for the bellhousing.

Still awaiting the rest of my parts.

2 questions....
Does anyone have a better write up or better pictures of the oil dipstick move? I still only semi understand the directions, and spaces looked tight when I was looking at it today.

Also, does anyone know what the pitch and length is of the manual flywheel bolts for the 3.4L? I need all of them. Or does anyone have some they want to sell?

Thats it for now...Thanks for everyones help

On the front of the engine, you'll notice that you probably have the dipstick tube going down into the driver's side front corner. You'll need to pull the dipstick (held in by the mount and a rubber O ring) and smack the guide (the part where the tube mounts) out with a chisel or punch and hammer.

Take a 1/4" tap and thread the hole. Take a matching 1/4" plug, wrap some Teflon tape around it and tighten it into the hole, On the driver side, matching the dipstick tube on your 3.0, you'll probably notice a spot where the hole is plugged or can be drilled out to match. I'm sorry I don't have pics of it.

Bolts...hit a wrecking yard or go to a dealership. Mine all came with the motor...

Scroll down about 1/3 of the way to post 36 and you'll see him tapping the front hole. Post 44 you'll see the new location.

Get them from the dealer, I have done that on a few engine swaps. They even come with the factory dry locktite.

Should be about $20

If you're using a pipe thread tap, I'd tap that hole from the top (I did). That way you can screw in the plug from the top instead of the bottom. Might save you from having to drop the pan sometime in the future if say the plug loosens up or falls out. When tapping from the top you'll have to use a wrench to turn the tap, but its just aluminum you're tapping so its not hard to turn.

For the original dipstick hole in the front of the block, I tapped it to 10x1.5mm. Didn't even have to drill. Then RTV and screwed in a plug:



Seems to be working so far.

Finally some motor pics

Here's the 3.4 and some of the parts. Should see the rest of the parts Friday. The wiring harness probably not till next week from what yotaman tells me.

Anyway the pics...

The Downey Headers...


Went wheeling today. It was awesome. I love my rig. Can't wait for the extra power of the 3.4!
