Rust in the Radiator?
So i did my oil change today and while i was at it i uncapped the radiator fill neck plug. Surprise surprise, the coolant was no longer cherry red but a more red-brown color. So i flushed out the coolant and while all the water was drained i looked inside the radiator. I could see brownish rust spots. Its wasn't like everything was in rust but their was definitely a good number of rust spots. So my question is if this is normal for a 1992 car or should i start looking into replacement radiators?

NO it is not normal it should not happen at all because the 1uz is an all alloy engine which uses an alloy radiator.
Should replace the radiator with an alloy supra tt and turn the radiator mounts upside down to make the radiator the correct height for the mounts.
Only use the red coolant (all alloy)

The green coolant is used for alloy, copper, cast iron or mix of all.

I think he means flush the engine and parts that are not the radiator before installing tha new radiator so that all the rust is out of the system so as to avoid another problem later.
