I was wanting to know what temperature a 1UZFE block would reach under normal operating conditions, with an typical ambient temperature of around 20-25 degrees Celsius

Also while I am asking what temperatures does the engine oil and coolant usually run at?

Cheers!

Block will be very similar to coolant temps.

Coolant temps from my measurements are typically around 90-95 deg C when hot.

I haven't measured oil temps.

The general consensus its that oil temperatures are usually 10 to 15 degrees hotter than coolant. Engine oil should not go beyond 105 degrees from my research.

Not sure how much ambient temperature will affect the block once it's reached it's threshold. The coolant should stabilize the block at the optimal temperature by design?

You can correct me if I'm wrong.

I guess that when you say "normal" you also mean a standard/factory 1UZ-FE?

Just with a TRD thermostat mine opens at 71 instead of the factory temp I think that is around 85. I guess that would be able to give you a ball-park figure of operating temperature??
