Do you really need to drain the coolant to replace the thermostat? How much
will be lost?

I got a PO128 troubleshooting error. The fluid level is fine. What are the
chances that it's the thermostat and not the ECT sensor?

Thanks

It should be drained at least to below the thermostat level. That way
all the coolant in the cylinder head won't come out of the intake
housing over the lower side of the engine, AC compressor, and all over
the floor. You're talking about ~1 gal for a typical drain so might as
well. But some coolant will come out when you take off the housing, so
be prepared to catch it.

Do use a Toyota thermostat and new gasket, distilled water (no
minerals added) and preferred Toyota red if you can still find it
(otherwise use prediluted Toyota pink, the long life GM-Dexcool
imitator without the 2EHA acid).
