Shops quote $1,800–$2,400 for this one, and the quote usually isn't the ripoff, the job really is that big. Here's what's actually failing, what the correct repair involves, and the honest part: this is not a job I do in a driveway.
The 2UZ-FE 4.7 V8 is one of the most durable engines Toyota ever shipped, million-kilometre examples exist, but it has one absolute dependency: a rubber timing belt that must be replaced on schedule, because this is an interference engine. The belt keeps the camshafts and crankshaft synchronized; if it snaps or skips, open valves and rising pistons occupy the same space at the same time, and the result is bent valves and a four-figure cylinder-head job on a truck that was running perfectly the second before.
The factory interval is roughly 150,000 km, and the trap is that a worn belt gives almost no warning, it doesn't squeal or tick like an accessory belt. It just ages: the rubber hardens, cracks form between the teeth, the hydraulic tensioner loses its hold, and one cold morning it lets go. Most 2005–2009 trucks are now on borrowed time against a second belt interval, and many have changed hands with no service records at all. 'Unknown history' on a 2UZ means overdue until proven otherwise.
The water pump is driven by the timing belt and hides behind the same covers, which is why the proper job is always a kit: belt, water pump, tensioner, idler pulleys, and the front seals if they're weeping. Doing the belt alone and having the original pump seize a year later destroys the new belt and repeats the entire labour bill.

Timing Belt, Water Pump & Tensioner Replacement is on my published list of jobs I turn down. It needs a hoist, a press or a machine shop, and I work out of driveways with hand tools. That list is public on my trust page. I'd rather lose the job than learn it on your engine, and you should be suspicious of anyone who says yes to this over the phone.
So here's what I can genuinely do for you, holding a $1,800–$2,400 quote. Both are real, both are flat-priced, and both are worth more than a bad yes.
Before you spend $1,800–$2,400, have someone independent confirm that's actually what's wrong. This is a diagnosis, not the repair, no hoist, no lift, nothing comes apart. I scan it, test it, look at it with you, and tell you straight whether their diagnosis holds up. If it does, I say so and you go pay them with confidence.
Book the second opinion →At $1,800–$2,400 on a car that might be worth not much more, plenty of people replace instead of repair, that's a completely reasonable call. If that's where you're heading, get the next car measured before you hand over money: 150 published points, at the seller's location, written report the same day.
Book a pre-purchase inspection →Tell me what you've been quoted and what the car is doing. $100–$250 flat, at your location, and you get a straight answer either way.

Not so you can do it yourself, so you can tell whether the shop quoting you understands the job:
That's the job. It's why this one belongs on a hoist instead of in a driveway, and it's why $1,800–$2,400 usually isn't a ripoff, it's a big repair honestly priced. What's worth checking is whether that's really what your car needs.
Get the diagnosis confirmed firstPlain version: Timing Belt, Water Pump & Tensioner Replacement needs equipment a driveway doesn't have, a hoist to get under it properly, a press or a machine shop for the parts that come out, and a controlled space for an engine or gearbox that's in pieces for days. I work out of driveways with hand tools. That's not false modesty, it's the published limit of what I take on, and it's listed on my trust page alongside the warranty.
What that means for you: this page is here to tell you what's failing and what it should cost, so you walk into a shop knowing the job instead of nodding at a number. And if you want that number checked before you pay it, that part I can do, $100–$250 flat, at your location.
There's no graceful failure mode here. A timing belt doesn't slip a little and warn you, on an interference engine it works perfectly right up until it doesn't, and the moment it fails, the repair changes from scheduled maintenance into bent valves, a cylinder head teardown, and a bill several times this job's cost. Every cold start on an overdue belt is a draw from a shrinking deck. If the history is unknown, the belt is due, that's the only safe assumption.
Partially, we can pull the inspection cover and look for cracking and glazing, which catches an obviously tired belt. But a belt can look passable and still be eighteen years old, and rubber ages on time as well as kilometres. On an interference engine with unknown history, replacement is the answer; inspection just confirms how urgent it is.
Because it's driven by the timing belt and lives behind the same covers, the labour to reach it is the labour you're already paying for. If the original pump fails a year from now, it can shred the new belt on its way out, and you pay the entire job again plus possible engine damage. Pump-with-belt is the rule on every belt-driven engine, this one especially.
No. Timing Belt, Water Pump & Tensioner Replacement is on my published list of jobs I turn down, it needs a hoist, a press or a machine shop, and I work out of driveways with hand tools. I'd rather lose the job than learn it on your engine.
Two things, and both are real. A second-opinion diagnostic at your car, $100–$250 flat, at your location, so somebody independent confirms that's actually what's wrong before you commit to a $1,800–$2,400 repair. And if you're weighing replacing the car instead of fixing it, a pre-purchase inspection on the replacement, $149–$399 flat, at the seller's location.
Because the useful part isn't the wrench. It's knowing what's actually failing, what the correct repair involves, and that shops quote $1,800–$2,400 for it, so you walk in knowing the job instead of nodding at a number. If you want that number checked before you pay it, that part I can do.
