Hi all,

My question is simple: can you guys help me out? I got a 02 Lexus ES300 with nearly 120K miles. I've never replaced my timimg belt - about 90% of driving is highway....

Can someone help me figure out a list of parts I need for timing belt replacement. I already know I need timimg belt and water pump, balance shaft belt. I am looking for an expanded list of parts (detailed) I may need besides these two parts... Btw, drive belts and spark plugs have been changed already.

Hope you guys cen help!

Thanks in advance.

 

timing belt
water pump
camshaft seals (2)
crankshaft seal (1)

thats about it...you only have to replace the seals if they are leaking oil...i do it while im doing the t-belt because the covers are already off so why not

 

pretty much. if you're going to replace the water pump, you have to take off the cover and you might as well replace the camshaft seals and crankshaft seals. I'm not sure but you probably will need the idler bearings (upper/lower) and the tensioner.

 

not normally...ive never had to replace the idler bearings or the tensioner...

 

not normally but it's one of those things where since you're in there, you might as well replace it. The cost of replacing those two while you're doing the timing belt/water pump is much cheaper than paying for labor + parts just to replace those separately later on. Just my opinion.

 

Timing belt --- 13568-09080 --- $43.96
Water pump --- 16100-29085 --- $97.71
Thermostat --- 90916-03129 --- $15.18
Thermostat gasket --- 16325-62010 --- $4.46
Timing belt tensioner --- 13540-20030 --- $44.70
Timing belt idler --- 13503-0A010 --- $70.49
Adjust cam (?) Timing belt tensioner idler --- 13505-20030 --- $78.74
PCV valve --- 12204-20040 --- $8.64
Camshaft seal --- 90311-38034 --- $6.40 each NEED 2
Crankshaft seal --- 90311-40022 --- $6.36
Valve cover gasket --- 11213-0A010 --- $11.64
Valve cover gasket --- 11214-0A010 --- $11.64
Coolant --- 00272-1LLAC-LX01 --- $15.67

Feel free to scratch items or add some...
Regards.

 

list looks good...i still think its a waste to buy the idler and tensioner...
in my 4 years as a toyota tech i have never replaced either on any toyota and ive never seen an issue or had a comeback

 

I guess just inspect them when you have everything out to make sure the bearings are good and the seals aren't leaking.

 

good point. always DO inspect the seals/bearings/tensioner and replace if necessary. most of the time the seals dont even need to be replaced but theyre cheap and its easy to replace them while the timing cover is off

 

Since I plan to keep my car for at least until 200K miles, I decided to replace the following:

----------------------------------------
Timing belt 13568-09080 - $43.96
Timing belt idler pulley 13503-0A010 - $70.49
Timing belt idler pulley 13505-20030 - $78.74
Timing belt tensioner 13540-20030 - $44.70
Cabin air filter 87139-YZZ03 - $24.24
Engine air filter 17801-0H010 - $13.60
Valve cover gasket 11213-0A010 - $11.64
Valve cover gasket 11214-0A010 - $11.64
Water pump 16100-29085 - $97.71
2 gallons of coolant 00272-1LLAC-LX01 - $15.67
2 camshaft seals 90311-38034 - $6.40 each
1 crankshaft seal 90311-40022 - $6.36
PCV valve 12204-20040 - $8.64
PCV valve grommet - $3.84

Just an FYI, I found that www.irontoad.com has the cheapest prices around. Trademotion.com comes close 2nd, but they charge more for shipping.

 

its not just prices, sometimes the parts come inferior quality and the pulleys with inccorect bearings [such they will last less time]. hopefully you chekced into that/made a decision that takes that into account.

but you're right to replace all those things. very wise choice. its not just baout the car lasting longer time, that's hardly part of it, the real thing is your car will be reliable it will be more likely work for another 100K miles than if you didn't have those things replaced as preventative maintenance. only things that probably were highly unimportant the airfilter and the cabin filter

now you just need a plethora of tools to do it! and since it's a 02 and has toyota variable valves and therefore interference design, you must be berry berry careful . might want to buy or get [find on the web ...] the FSM [factory service manual].

random tip for you: i dont tend to use the white lines on timing belts. its all about getting the sprockets to line up properly once the tensioner is applied. on some cars, you turn the crank a degree off, others one of the camshaft sprockets a degree off. the FSM covers which to do, but you might find a slightly easier way[ not unheard of ].

another one, there is the starter blip to loosen the crankshaft bolt, but tightening the bolt is going to be more tricky. [with manual trans it's piece of cake because transmission can be put in gear and the tires used as resistance]

 

BTW, Why is Lexus so late to the party? Their Japanese rival Infiniti has been using maintenance-free timing chain as far back as 1990. Really way ahead of their time. I know that my 1992 G20 5spd mt has timing chain. I believe Lexus started using timing chain in '06 perhaps '07. All this worries about timing belt wouldn't have been a concern if they have reciprocated infiniti.
Now, I have to look into having the timing belt on my '00 ES changed. It has 122k miles and I don't know if the previous owner changed that.

 

Timing chains tend to be louder. Kinda goes against the whole Lexus "quiet" thing.

 

timing belt vs timing chain --- doesnt make infiniti way ahead of its time. you dont know what you're talking about.

timing chains wear out, but cost more to replace -- though in many designs they last a long time.

timing chains tend to make the engine noisier, especially at high rpm, especially once the engine is old [like 100K miles]. so timing belt is quieter in most situations most of the time.

timing chain offers a little bit better tming of the parts -- so the valves open more precisely at the time they are supposed to over the rpm range.

timing chain is cheapier until it breaks or other problem.

timing belt breakage wont tend to hurt engine parts like a timing chain can.

timing belt slightly energy better efficiency in some designs -- so, you would get more performance [possibly also better fuel economy] from same engine all things being equal. think about it in just one of the simple reasons why this is so: hold a timing chain, hold a timing belt. which is heavier? thought you could argue that the better synchronization of the valve timing with crank position would over come that, it alawys depends on the design of it.

this toss up is kind of why its a toss up of whether or not a jap v6 will be one or another. if you could make the timing chain quiet, last long ,and impervious to wear and tear, than you would tend to want to use that. there may also be engine power characterisitcs that come into play -- chain might be better for fast reving/performance engine or high RPM
