Parts you should have replaced with the timing belt

[Dan.3]

Hi everyone,

For those of you who only had the pump and belt replaced, are there any regrets to not having everything else replaced such as the pulleys and seals? To clarify, does any have 250-300k miles on their idler pulleys?

Im getting quotes on have the dealer do the timing belt and water pump on my 99. Its the original belt and pump with 206k on it. Appears my water pump is starting to leak so I might as well get it replaced. Im going to have the tensioner replaced with it but Im on the fence about the other two pulleys and the seals.

I have seen all the posts about having the pulleys and seals replaced but no one has mentioned personally experiencing anything negative by only replacing the belt and pump. I have thought about buying the crankshaft tool to remove the bolt and doing the job myself but, Im not sure I want to deal with all that on a weekend. For $600 in labor, Im thinking I would rather just pay the money and enjoy my weekend.

Buy the OEM/Asin kit off eBay or Amazon that has all the parts recommended to be replaced, including accessory belts, thermostat, radiator cap, etc.

Im well aware of the kits. Its a matter of working on my rusted engine for a day on the weekend or enjoying it. But thanks for not answering my question :biggrin2:

I had all the parts replaced, no regrets. Next question

there is no answer to your question because no one here would have done it that way to risk other failures/problems besides the belt and the water pump.

At the very least I would replace the radiator and hoses

If one of those idler pulleys seizes up, it'll wreck your new belt, and then you get to pay the labor all over again to get it fixed, so that 600 dollar job just became a 1200 dollar job, plus the vehicle downtime, plus the cost of the parts.


Only recommended parts I did not replace were the crank bolt itself (dealer said they reused them all the time anyway), and the cam seals, which showed no signs of leaking. Next timing belt, I'll probably do a new bolt and will definitely do new cam seals.

Lmao this is something you do once. I just told the mechanic to replace all that crap so I don't need to waste my time thinking about it on t4r.org all day.

I did everything minus cam seals. Radiator, radiator hoses, water pump, thermostat, crank seal, crank bolt, tensioner, pulleys, timing belt, drive belts, and probably more. It was my first timing belt job and it took me just over one day. I knew it was done right, and everything was replaced the way I wanted.

At 206k I would replace everything. It will run noticeably quieter with the new pulleys.

I think he did answer your question:

I'd do all that and only hesitate on the seals if they were *absolutely*bone*dry*. Because there is some slight risk in taking those out and getting them reinstalled properly. But if they're even the faintest bit oily, I'd do those too.

They only last forever if you maintain them like they're going to.

No, the kits mentioned do not include pulleys and seals the OP was asking about.

"For those of you who only had the pump and belt replaced, are there any regrets to not having everything else replaced such as the pulleys and seals?"

Those people (if they exist) regret not replacing everything else when they were told to by everyone else. They (can't be more than one or two) also feel supremely alone in their regret, as nobody else harbors those regrets because they replaced everything else when they were told by everyone else they were supposed to change everything else...So the moral of the story is...Change everything else, or else...

I guess it depends on the kit. https://www.ebay.com/itm/Toyota-3-4...Kit-/190521450224?vxp=mtr&hash=item2c5bf69ef0

$600 is just for the timing belt and water pump. Just wait for the price tag shock when you tell them you want to replace the tensioner, pulleys, crankshaft seal and camshaft seals. Even though it's not really that much more labor, I bet they ask for $200-$300 more.

 

[alumarine]

I recently had a leaky water pump.

I replaced the timing belt, water pump and tensioner bearing as they needed replacing.

I did not replace the tensioner or the upper idler pulley #2 as they were fine.

I have no regrets.

My truck went to the dealership and got all the belts, pulleys, seals and water pump replaced with oem goodies. And I got to spend my time rock climbing for the next two weekends. No regrets here. And I feel better knowing my 21 year old truck has new parts and should be good to go for another 90k without worrying about a seal failure.

 

[spmarfatia]

I just did all the goodies, like 15-16 different THINGS that came in that particular timing belt kit at 195K. don't want to be messing with all that anytime soon!

Geez !! Simple answer do your seals, tensioners while your there. Why pay double down the line for 50.00 worth of seals? Seen a couple of people regret this pic on one attached

Aircabin man on eBay sells a whole kit for 300.00 and it’s all you need.

Are those pics a result of a seized water pump or idler?

Unfortunately, the dealer will not order from aircabinman. Per the forum majority we should all replace the timing belt every 90k or every 6 years or whatever the time limit is. Yet its been 19 years and 206k miles and here we are, still all original factory parts. Just trying to find out how far people have pushed their machines. Obviously, it not necessary to swap everything out every 90k miles as most of you believe. So it raises the question is it necessary to swap out the idlers at 200K?

Ill probably cough up the extra 400 to have the pulleys replaced as well by the dealer too. I dont care to the the guinea pig and find out to see what happens. I was just asking if anyone has skipped replacing the pulleys and has well over 200k with the orginals.

At almost twenty years old, replace as much as one's wallet will allow. Time is not on your side here as far as longevity of components go.
