This lines leaking, indicates rust deep into all cavities. It's going to be a money pit, with very little resale valve if that the case.
I'll take the opposing view, for a momentum. Please don't take offense.
Aisin fan bracket (FB) & V-belt Tensions ~$250 parts alone. Add that to other parts, comes closer to $500+. As I said, I would recommend Toyota Aisin FB, at closer to $400, for that part alone. Why, I see better casting appearance on the Toyota Aisin. This is not to say Aisin FB bad. But considering, I've seen engine blown, due to failed FB. It's worth extra for the piece of mind, IMHO.
It's not fair, to compare a minimal T-belt service. Which I've see $900 to $1,200 ($600 to $900 pre 2021) range. I've seen where even at Lexus Dealership, tech only changed the T-belt, nothing else! Not even water pump. Charge over $1,800.
You get what you pay for, at best.
Here is one, I came behind T-belt service, that in $1,200 (pre 2021) range IIRC. To correct what was believed a blown engine, because of failed t-belt service. Fortunately, it was not a VVTi. So much of what I do, is correcting what other hands have touched!
Happy 2020 all. Well, I spent last day of 2019, inspecting a 2005 LC w/~200K, that was towed to me. That had a Timing Belt installed a few days before coming to me Let me know your thoughts: Blown engine from interference or is there hope? Also what do you think happened? Skip story and go...

The fact the OP's estimate here, is listing so many parts, but not cam seals. Parts like, thermostat, Tees, FB & V-belt tensioner, coolant, etc. Indicates a shop that knows what they're doing, when it come to 4.7L VVti. Personally I would not do crank seal unless leaking. Which I've yet to see a factory installed crank seal leak. Even at 400K miles & 25 year old. The only crank seals, I've had to replace, where R&R previously.
I come behind these cheap 1/2 day T-belts service most times. I get to, clean-up their mess. I find missing bolt/nuts, bolt/nuts not installed with torque wrench (being to tight or too loose on same part). Bolts not thread on by had, cross threading them. Missing parts, damaged parts. oil leaks, wires routed wrong, etc.
I'm doing one now, on a VVTi. Finding the typically signs of a bad T-belt job. In fact everything I've work on this one 06LX, that was touch by another shop out of CA. Has been messed up. In this 06LX; I found the T-belt tensioner bolt, was cross threads in. So now I'm having to replace the Oil pump, tying up my shop and extra week (I'm not happy). Which is, one of the bigger more costly services. Same labor as non 100 series engine, into a 100 series R&R.
I did a remote PPI yesterday. Found shop, known here in mud. Recommended oil pump replacement, for no apparent reason. Other than baseline. I'd never do as PM or baseline, never. They use customer supplied Aisin oil pump, rather than Toyota Aisin. Bad, they installed the wrong oil pump. Few know, that the VVTi had a oil pump change. Failed PPI, for that and few other service history entries of shop repair red flags.
Most shops, do T-belt in less than a day.
My T-belt services are
typically 3 days. But, I'm not trying to beat the book flat rate time. I'm working, to get back to factory spec, and last a lifetime.
- Day one: clean radiator fins, skids, engine and bumper & fenders. Drain coolant from rad & block and tear down removing water pump. Clean block and fill pits on block under water pump gasket, with 1282B FIPG. Let cure overnight. It takes, extra time and effort, buts mitigates future pitting.
- Day two: Cleaning, repair and assembling.
- Day three: Finish burping coolant system. I've had to replace engine after a t-belt service, because this step not done.
- Additionally; My Torque wrench is the most used tool, I use during any assemble. Most tech, don't use one, as it takes extra.
Extra care must be taken, setting cams and crank at specific points. During tear down before belt removed on VVTi. Most tech aren't aware of this, for the VVti. You get what you pay for at best.
There's a thread now on a rig went to Subra/Toyota INDY shop. Just for rack & pinion R&R. His engine blew 5 hours out. Not enough coolant, resulting in over heating. I've no doubt they used FSM method to R&R R&P. Which I come behind often, to stop oil filter bracket leaks. Because of FSM method used, but not taking time do to by the book. You get what you pay for, at best.
With bad rust, it's time and materials toss estimate out the window. In OP's, it's likely best deleting AHC. Which I never like recommending, as I love AHC.
Needs second look. But I've seen my share of 75K to 150K badly leaking racks, with shot bushing. Often time TRE, LWR ball joint and wheel bearings also bad. It typically starts with improver servers of wheel bearings and or power steering fluid flush or lack of and not correcting leaks from above dripping on bushing of R&P. You get what you pay for, at best!
