What else to replace while I’m in there for the water pump

[sleepintheback]

My 2013 LC is coming up on 135k. Something is leaking coolant, and I think it’s the bottom of the radiator. My water pump is weeping a little too. I’m planning to replace:
Water pump, idler+tensioner, belt, all radiator hoses, and the radiator itself. Should I throw in a thermostat while I’m at it, or is this one good for another 100k? Anything else I should replace while I have the radiator out?

I can’t seem to find an expansion tank anywhere. Is it built into the radiator or something?
Lastly, does anyone have a diagram of where all the different radiator and coolant bypass hoses should go?

I'm cheap as anyone, but I would for sure replace the thermostat. That's a lot of heat/expansion cycles. It's very cheap insurance against overheating, which as you know can lead to very bad outcomes. Just my two cents.

Starter perhaps? Idk how much is duplicate labor, but they seems to go around 150k

I just did this too - I did radiator, hoses, water pump, starter...and a bunch of other stuff.

Do you have to let the coolant out to replace the starter? It looks like that comes out the passenger side wheel well. I’m only trying to avoid taking the same area apart multiple times within a couple-few years.

No, they share very little work.

Sorry - should have been more specific. I had Toyota do mine

I found some other coolant related parts to replace: the heater tees and related hoses. Part # 87209-60C01 and 87209-60C12
I’m still looking for a diagram of all the coolant bypass hoses.
