Something timing belt-ish failed (1 Viewer)

Can you elaborate on the procedure to get everything aligned?
How do you "know" it's been replaced once? What's the condition and brand of the belt?

There is a sticker on the radiator shroud. I can make out timing belt and it shows the milage that it was done at, but I can't make out the numbers. I'll have the belt out today and know more. I haven't looked at it much. I've just been taking parts off, coming back to this forum, to YouTube, and back to the garage.
My wife is picking up a crankshaft pulley puller right now. Thanks so much for all the help so far. This forum is invaluable.
I’m still a little confused on lining up the timing marks. I think I have the procedure to follow, I’m just nervous about turning the cam gears. I’m not 100% clear on what I’m lining up.
This is part 1 of 2. Great tututorial and helps a ton

Cam sprocket protected by piece of old timing belt, can be held with chain wrench. Just use care not to damage.
In the none VVT engine like your 03, guys in mud have turned the crank 360 deg with belt off. Not once have they run into interface (piston hitting a valve). So don't get overly concerned with marks, except during assembly.
With crankshaft set to TDC, the #1 piston is at top of cylinder. Which happens when mark on harmonic damper (circled in red ) aligned to zero on dial (not pictured) that is fixed to lower timing belt cover. TDC of #1 cyl can also be set with timing mark (notch, red arrow points to) on crank sprocket and mark (bump, yellow arrow points to) on oil pump housing.
Crank Marks for belt are seen here:
With LH cam timing marks aligned, the #1 intake & exhaust valves are closed for compression stroke. We must also aligned RH cam marks. Then belt ties it altogether.
This is a VVT engine so cam sprockets looks a little different than non. This sprocket is about 1/2 tooth past (CW) the mark on engine.
Yellow arrow points to timing mark on engine. Red arrow points to mark on this cam sprocket which is about 1/2 tooth past (CW) the mark on engine.
Mark sure to NOT use the "T" for cam marks timing mark.
In these pictures sprocket happens to be about 1/2 tooth pass (CW) of the timing mark on engine.
Tips:
Cover radiator with cardboard.
With all spark plus out, it makes turning crank easy.
Cleaning harmonic balancer and crankshaft then adding a little grease where they mate, makes slipping on and off easy.

My wife got home with the rented crank pully puller, but it didn't work. My dad helped me make this. My only concern is bending the bolts , or worse, breaking them off in my pully when I start to torque it. I figured the screws are going to have to be 2.5 inches long to reach inside the recessed pully bolt holes.
Kit should be here Friday.
Time to clean up for dinner. Merry Christmas everyone.

Short piece of old drive belt to protect.
Remove oil sending unit to make room for chain wrench to hold with 3/4" breaker bar
Torquing on.
Use a dab of 103 FIPG, on threads of oil sending unit during install.

Gonna finish gathering a few things today.
1. I have to buy a chain wrench. I don’t have an impact gun and I need to take the cam gears off.
2. I need to buy a seal remover.
3. Seal packing. Damn! $93 from my local Toyota dealer! I have some Toyota FIPG from a head gasket a few years back on an 80. Some threads in other forums say just use that. Some recommend Permatex. Some say NEVER USE ANYTHING EXCEPT FSM RECOMENDATION. I gues I have some decisions to make with that.

The FIPG, is it for the water inlet?
The main reason for 1282B fipg is compatibility with SLL coolant. Use a different coolant and You can use the cheaper fipg. Fwiw there is 1282B fipg on Ebay for around $30- several have reported its legit. Maybe someone will post the seller link. Aisin makes a multi coolant compatible fipg- I read a post from Cruiser Outfitters a while back who stock it. Personnaly this isnt the place I would experiment with alternate fipg because I use the Toyota SLL and dont like redoing work. If it makes you feel better, I think a good many shops and toyota dealers dont use the specified 1282B and use the 103 or the permatex ultra black. It just may not have the life span when using SLL Coolant.
As for all the tools you dont have: go to napa, orielies, autozone whichever is convenient to you and use the loaner tool program. Or maybe there is a mudmember near you with these that you can barter for a 12pack.
The seals can be removed with out a special tool if you are super careful not to scratch the mating surface (race) but it requires some finnesse. You dont need an impact wrench, but a 20” breaker bar and a harmonic balancer puller holder; leverage is your friend. Im not a fan of chain wrench because of the potential for damage on the pulley but to each thier own. I prefer the holders that screw into the pulley.
Good luck

I'm sure the Toyota/Three Bond fipg is a great product, but I successfully used Permatex's water pump and thermostat gasket maker.
Its been over 3.5 years and ~34,000 miles since I did the work and I've had no leaks or issues. I did make a point to follow the instructions which include letting the gasket maker cure for over 18 hours before adding coolant which was inconvenient.
^^^Yes I think the key success with other fipg options is the cure time before adding coolant. Great point!
Just wait 24hrs to let it fully cure before you add coolant.
Not sure how old your coolant is but unless the coolant in your system is new ( like couple of months new) its not good practice to reuse the coolant. Its only $15 a gallon for Toyota SLL.

Borrowed a chain wrench tonight. I tried using my homemade tool, but as expected, the screws are flexing and bending.
I don't want to order and wait, nor do I want to spend $65 money on a rarely used tool and no parts store had one. But I wish I had one.
I'm going to try and avoid removing the oil sending unit unless I have to. If I do have to remove it, will I need to drain the oil?
Decided to flush and put Prestone universal 50/50.
Kit will be here tomorrow sometime. Gonna watch some videos on removing cam seals.

Oil sending unit can be remove without draining oil.
You'll want a piece of old drive belt (serpentine) to protect groves of harmonic pulley groves. So you may want to pick up a new one. You can just put the chain wrench on pulley unprotected, but it will leave marks.
I find chain wrench marks all the time from Toyota/Lexus Dealership T-belt jobs.
The Toyota coolant is good stuff. I highly recommend you use the recommended Toyota coolant red or pink for your year and stick with it through the years.
I used this and it works fine. Would recommend Toyota coolant though
