Take good care of that oil cooler assy 15710-54030.

I was crazy enough to buy a new one at ~$600 just so I could say I truly had a new 1FZ-FE long block minus the valve cover because NLA.

I’m probably only a handful of people to have ever bought one from Toyota. SMH ocd
why pay so much? it's only like 300$ out of japan.

New one on my engine as well. They get clogged up with sludge over the years, ya you can get them cleaned out pretty good but I like new parts on my new engine.

FYI, if you buy a new cover it comes with the check valves and related parts.

Cheers
 
If you leave it over night it might. One or two five minute cycles and a rinse in fresh water has never been a problem for me.

I was crazy enough to pick one up for $335. I've read that some builders won't warranty unless you replace it, fearing some trapped bit of metal will escape and wreak havoc...

Not anymore. Mine came with zip. Fortunately the bits and bobs are not expensive.
 
For future searches: for the 1FZFE there's a bare oil cooler cover (15721-66010) that is just the cover, no extra bits.

And there's an oil cooler cover sub-assembly (15701-66010) which comes complete with the valves, springs, etc:

And then the oil cooler assembly (15710-54030):

I have my exhaust manifolds off right now to fix a manifold and downpipe leak as well as replacement of downpipe, cats, essentially the entire exhaust, lol. Thinking that I should do this while its accessible. My main question is, do I need to drain the coolant and or oil from the system to do it, or can I leave that in? I just flushed the radiator and changed the oil so I want to avoid that if possible.
 
When sitting oil drains down into the pan and this is above the pan so don't have to drain. Might be some residual but shouldn't be much
Thank you! Its been sitting for a week or so now, so I think I am going to pull the trigger on this.
 
For coolant it's a lower point in the system so some of that will drain
I guess I might as well also replace the thermostat while doing this as well. I just purchased this and not sure when it might have been replaced last.
 
Did the oil cooler job yesterday. Wow, glad I did that as it was in bad shape. Besides being filthy with corrosion, the piston that moves up and down with the spring was seized in the housing. Did the thermostat as well. Lost a lot of coolant, lol, so will need to refill once I get my exhaust done.
