Prior to the timing belt failure, did you notice any distinct or unusual noises from the engine?

[@carloferri7437]

@@tannergrubb I did. It felt like a miss in the timing. I took it to a mechanic, and he thought timing as well. We pulled all the plug wires and searched for arcing, but couldnt find anything. Changed the wire for one of the cylinders, as the code we were getting was a miss in that cylider, but it didnt correct anything. I should have guessed it was the belt, but didnt occur to me at that time. Now makes perfect sense. There was no noise, just the occasional bump during acceleration.

Perfect video. I wouldn't have been able to do the water pump job without it. Be careful reusing old bolts on top of the fan bracket. I had the torque wrench set 3lbs to high and snapped one of the upper bolts on the fan bracket off. That basically means redoing the whole job but I decided to drive it until it leaks. So far so good....

[@fuai2029]

Thank you, and I much appreciate your explicit instruction videos on the timing belt replacement. It was my first time replacing a timing belt on my 2005 Toyota Sequoia SR5 4WD. I followed your part 1 on removing parts, then part #3, putting parts back and torque specs. I would like to thank this KZbin content creator ( kzbin.info/www/bejne/g2bUq42QhMSGe5o ) for tips on aligning the timing belt top pulleys to the "T" after the top dead center and then removing the old timing belt; I ignored the Toyota's manual's confusing instruction on rotating the crank 50 degrees after top dead center. The top timing pulleys did not jerk. And also, thanks to this KZbin content creator (kzbin.info/www/bejne/b36WmXmJnrCmlbc ) for removing the other parts before following your part 1 video. For anyone curious, my sequoia top pulleys did not look like those in the video. Mine have covers. It was a miracle. It was the first time my 2005 Toyota Sequoia ever got the timing belt replaced after 105k miles and 17 years. I followed the advice of a DIY mechanic who told me not to replace it before 100k. The factory timing belt still appeared to me it was in good condition. Please do not do what I did; follow the manufacturer suggested maintenance schedules.

[@christianmichael1970]

We need a better view of the front of the engine.... LOL Great video thanks for making. This does make me question a few things as a potential new 4runner V8 owner which is why I'm doing my homework BEFORE I buy. After watching you get to the timing belt with all the room in the world, how difficult is it to get to the other serviceable parts of the engine as in Alternator, A/C compressor, power steering pump and water pump when in the car? Or is it a case of you have to strip the engine to get to it all? I've had V8's and V12's that appeared had more accessible parts. Thanks in advance

[@OTRAMM]

Access to the power steering pump and AC compressor are decent. The alternator is a bit buried but not too terrible. I can count on one hand the alternators I've had to do so there's that as well.

[@ISSPICYU-FJ]

Great video OTRAMM. As always, very informative. One question I have is, the Haynes manual for my '04 Sequoia says to set engine to TDC (as you also shown) before removing timing belt. I've seen other comments about using the 'T' mark instead, which supposed to be the 'Timing Service Position' Is this correct? What does the 'T' mark on the cam gear mean? Am going with the manual anyway but I was curious. Thank you.

[@OTRAMM]

The t mark seems to line up with some years of timing belt but not all of them. Follow the manual for your year. I'd trust the manual that comes with an Aisin belt over the Haynes if you have both.

[@gregpeyton2754]

Great video series. It was very helpful when I replaced my belts several years ago. Unfortunately, being a novice mechanic, I may have done a poor job with the seals. I'm going to have to go back in to find the leak, which is probably the crank seal or the oil pump. Can the oil pump and/or seal be replaced by lifting the engine a few inches on a 2WD Tundra? I don't have the room or the resources to remove the engine but I can lift it a bit if it would work.

[@OTRAMM]

I've never tried doing it in the vehicle. I've heard it's possible, but I don't know for sure. Getting the oil pans clean enough to seal will be the tricky part with oil dripping down

[@OTRAMM]

It may be possible to do it in the truck but I don't see how. The oil pans have to come off to get the pump off. You'd have to lift the engine up pretty high to get enough clearance.

[@OTRAMM]

We left the transmission in on this one. Now that we have a gantry crane we usually pull the whole drivetrain. No need to pull the motor for just timing belt though. We were doing the oil pump as well so pulled it for that.

This is a great video series for the 100 Series owners. Thank you. I am avid mechanic but have not had to do a timing belt/water pump job on a 2UZ yet. For the 06/07 VVTi, is the method of aligning the crank pulley and cam pulleys the same? I realize that you stated the location of the alignment is different depending on the model year and I am still in the process of doing my research but figured I’d ask now. Thanks

[@OTRAMM]

It's mostly the same procedure. The angle you set the crank to will probably be different. The factory manual and the guide that comes with Aisin timing belt kits show the proper angle.

[@EpicDave168]

I used this video as a guide when I did the timing belt service on the 1UZ-FE engine that is in my Toyota Epic boat. It has VVTi and the factory service manual stated to set the engine to 50 degrees past TDC - that will set the timing mark on the cam pulleys to the "T" marks on the heads. This video is awesome and the engine has been running like a top for years after the new timing belt was installed, so I think this is correct.

[@OTRAMM]

A lot of Internet people take the while you're in there mentality way too far replacing things for no reason. Like, there's no reason to ever replace the crank bolt unless it was somehow damaged. The videos are filmed on vehicles we're repairing at the shop. With customers paying the bill we can't just throw everything possible at it. That said in the years since those videos were made we have seen some parts start failing more often and include those now as well. We do the timing belt, water pump, all the timing belt idler pulleys, the timing belt tensioner, the fan bracket, serpentine belt tensioner, and the thermostat and heater tees as the standard job now that everything is several years older.

We use the Aisin timing belt kits. They're high quality Japanese parts. There's a link to them on Amazon on our website. The belts are 90k or 5 years for the interval. Technically it's due now by age. Depending on what was replaced in the last job and the quality you may be OK to go to 200k but it's hard to really know for sure.

[@paule6865]

Totally confused as to which marks to line up to based on your comment in 17:30 of your video. You say to rotate it past "0" 50 degrees. A thread I read says: "When the engine is at TDC the pulley marks on the crank and cam gears line up with the single straight mark. PRIOR to removing the belt, rotate the engine slightly clockwise until all gear marks line up with the "T" (Timing Service Position) This ensures that NONE of your pistons are any longer at TDC, where a slight "snap" from a cam could bend a vale. These "T" marks are where you line up the marks on the belt." The Dayco instructions say "0" on the Crank Pulley and the red marks on the Cam Pulley. Trying to figure out which is correct. I have a 2004 Tundra 4.7 V8. TIA

[@OTRAMM]

As I say in the video it changed by year. There are 3 different positions by generation. You've got to look up the instructions by year. I've never used a Dayco kit so I'm not sure what their manual looks like. The manual in the Aisin kits breaks it down by year. The factory manuals also break it down by year.

[@nicholash8021]

Other videos have proved that the manual is wrong on this and taking the advised 50 degree forward/backward rotation often results in the cams slipping. There is a reason the manufacturer put the "T" on the engine and that is because it's just enough to clear the valves but not too much to cause the cams to slip. I just replaced my 06 timing belt using the "T" marks and it worked perfectly. If you also see a paint mark on the T from the factory, that should be extra assurance.

[@OTRAMM]

The degree of rotation varies by the year of the engine. There isn't a one spot fits all. I'll continue to follow the factory manual until Toyota releases a change. I doubt "other videos" have the engineering background Toyota does. They're procedures were developed for a reason.

[@nicholash8021]

You need a manual for the specifics. If you get an Aisin timing belt kit it comes with a decent guide.

Thanks for the Step by step process, my confusion lies in the fact you say this is an 01, and according to your book you turn the Crankshaft 50 degrees past TDC. In my book it says you do this only with 05 models and 50 degrees back the other direction for 06 models. Another youtube video the mechanic says the from 00 to 04 you place the crankshaft on TDC. That 2005 to 2008 you advance 50 degrees. Can you please clear up this confusion for me. Again thanks, the book is confusion and I am a very visual learner.

[@jayinla228]

You're right, I also noticed this mistake, perhaps this year specifically calls for 50⁰ forward? Maybe he can chime in.

[@OTRAMM]

You have to look the rotation up by year. There are several different settings by year and vehicle.

[@mickeydoolittle2057]

Ok, stupid question, you set to the zero index mark with the other cam indices aligned, why would it matter? You just slide the belt on with the valve train set in this position, then it should be good, no? What is the magic of rotating another 50 degrees. I have a 2001 Sequoia with 255k, I need to do it, this video is great, but I need to make sure on this step.

[@OTRAMM]

You need to know the spec for your specific year. It changes by engine generation. The extra rotation puts the Pistons in a position where they're less likely to make valve contact if the cams move.

So which is more reliable? VVTI or Non

[@OTRAMM]

I haven't noticed any difference between the two

At 17:28 I’m looking for that tool. Can’t find it on the website. Crank holding tool.

[@fatheadmeetoo2891]

And how do I find out about the top dead center revolutions for my vehicle? Where is that info?

[@fatheadmeetoo2891]

I have a 02

Do you see the oil pump leak on these engines often? I have a 2000 LC with 150K and so far it is dry....hoping that I don’t get that type of leak that would require pulling the engine to fix.

[@OTRAMM]

This is the first time I've ever seen one leak. Talked to a couple other folks about it and none of them had seen this leak either. Hopefully it's just a fluke and not a vision of the future :)

[@joeburris2836]

Thanks! My timing belt was done at 56K due to age and it is due again. Your videos are the very best! The only one that I have ever seen that references rotating the crank passed zero to avoid valve contact if the cams decide to spin! Awesome detail!

It's rare for the 4.7 to leak oil and if it does it's usually the valve covers . The 4.7 is a tough engine but I'm sure there are lemons out there. Rare though....

[@Milttode]

You’re fucking awesome thanks so much

[@mrpegasus33]

Would you recommend other mechanics to pull then engine for this job to save time and grief ?

[@OTRAMM]

It's an easy job in the truck. We only pulled the engine because we needed to to change a leaking oil pump.

@@OTRAMM thanks mate
