timing belt diy issues

[steelynorm]

So started my timing belt replacement today and am stuck.
Trying to take off thermostat housing/ water inlet.
It moves leaft and right with a whack of rubber mallet.
But can not remove from engine?
Looks like there is fipg around inlet area and on base.


Seen a couple of these break on some threads. How to remove without damaging?

Your gonna be ok as long as it has SOME movement. Mine was the same way. I just kept hitting it with PB blaster where it connects and tap back and forth and hit again with blaster... it took a looooong time and eventually came out. Had a buddy that helped by pulling on it while i tapped it to encourage it to back out. Main thing is to pull straight out as you tap and dont tweak it. That thing is the s***tiest design, right up there with the dissimilar metal parking brake levers that rot out and seize in the full float rears. If you had no movement then you risk the chance of busting it off, which someone covered in another thread... It should tap a little further every time. I think it took me about half an hour of back and forth going easy. They give you the new oring in the kit, and also use some dielectric grease on it for next time, and on all your hoses or any rubber sliding things makes them come off super easy down the road. Good Luck!

Like the last poster said, go easy. It may help if you have someone pulling straight out as you tap. I gave it a little too much of a tap and cracked the crossover pipe it goes into. I didn't know it at first, but it definitely had a hairline crack. It delayed reassembly by a week and cost me somewhere around $150-I can't really remember at this point. I'm just glad I noticed it.

If the 90k service has been done before, then the smaller gasket is probably rtv, not the oem gasket. This would most likely be what is giving you issues.

From the photo it looks like the serpentine belt is in the way of a straight back pull. Remove that first.

This ^^^^

Plus, looks like you have the fan shroud, fan assembly, etc., still in the way. All of those need to be removed to get to the timing belt. You can do the service without removing the radiator, but if you have stuck bolts or other issues you can pull it also then you have room for impact guns and such to make the job a little easier.

That video posted by 2003lx470 is actually a three part series. I used this series to do my service with great success. The only thing from the videos you don't need to do is drop the AC compressor. Leave those bolts in until it comes time to actually remove the water pump. At that time you will see the two bolts that need dropped--while still leaving the compressor in place.

Also, the homemade tool for tightening the harmonic balancer is debatable. There is a specialized Toyota tool that runs about $70 dollars.

Good luck.

Videos do look good. I'll be doing this in a year or so as i just hit 160k mi. Do you happen to have the number for the Toyota SST to re-install the harmonic balancer? Also, did you need the harmonic balancer puller to remove it?

While doing this procedure, I will also be replacing the radiator (my last one cracked at about 200k/12 yrs on the 80-series), the hoses for the oil cooler, the fan bracket, cam seals, fan clutch, while I have all this apart. These are items that I had to replace near that milage/age anyway, so I figure I might as well do it while it's all apart.

I did use a harmonic balancer puller, a cheap one I picked up for $10 from Amazon, and it seemed to work fine. The tool you are looking for to re-install is available from a number of places--the most common listed is the Schley SCH64300 which shows that it will work on the Toyota 4.7. It runs anywhere from $65-80.

Stealership put a ton of fipg around neck, dental tool heat and silicone and lot of swearing and praying paid off finally thanks for your assistance everyone.

Next question, I have 220k should I replace radiator as pm?
Everything looks fine no major corrosion that I am aware of.

So getting deeper into this, and the fan bracket pulley is toast.
Heard some noises before I started job, and parked the car because I knew I was doing timing belt service.
Might want to consider replacing fan bracket pulley during ur second timing belt change. Metal shavings were everywhere.

Anybody have pics on power steering pump bolts placements?

If the radiator and the rest of the cooling system look clean, I wouldn't replace it.

You could check it out generally with a pressure tester...usually you can borrow it from you local parts store.

I'm not sure what you mean... You put the bolts in through the pulley holes into the mounting bracket... Same as they came off.

I got into this job this weekend on my 98 LC. I hadn't done it since 95K and figured since she was coming up on 300K it was probably going to kill the beast soon if I didn't gitrdone. It went very smoothly following the Tundra YouTube video series.

Here's the amazing part - when I got the belt covers off, I found that the timing belt tensioner was completely broken (see photo). As luck would have it, the broken piece was wedged in below and somehow kept enough tension on the belt to keep it running. Who knows how long it had been like that - probably 100K miles or so. Was this genius Toyota engineering or cumb luck?

It amused me so I thought I would share.
