I'm about to replace the timing belt on my 01 3.4L. Here's the list of things I'm planning on replacing. Let me know if there's anything else I should consider while i'm there. Any pulleys or tensioners need replacing? It has 170k miles. I don't know if the belt has ever been done. I bought it with 150k miles. Should I get the parts from Toyota, or are there decent OEM equivalents? It's a big job, so I don't mind buying quality parts.
Timing belt
Water pump
Upper/lower radiator hoses
3 accessory belts
Thermostat
There are several online sources for the parts. Just beware that some sellers claim to sell OEM parts but don't actually supply OEM parts. There was another thread on here of various Ebay and Amazon sellers of the parts.
Hydraulic tensioner and bearings should be on the list (usually included in a kit anyways). Some kits have 'OEM' parts but then go cheap on the bearings. Make sure the kit you buy has Nachi (OEM) bearings.
I wish I had put the kit I purchased in my notes, it was all OEM. I think it was this one by TBK: https://www.amazon.com/dp/B0039VMSCU?tag=vs-auto-convert-amazon-20
Some people replace the crankshaft bolt but plenty of people reuse the old one. It is just a bolt.
