Make sure your secondary fan is coming on. primary 220 secondary 234. Then remove the cover on top of the radiator and look between the condenser and radiator for debri. Which temp sensor did they change ? under the left exhaust manifold is for the gauges. the one above the distributor is for the comp and controls the fans. If you disconnect this one both fans should come on if the fans are working properly.You also have 2 brass bleeder screws ,try bleeding the system. If all else fails remove radiator and have it cleaned and inspected. 93t/a owner

1; Radiator and block need to be boiled/flushed out, then flushed clean with clean water (Thermostat out while you do this).
2; Replace hoses, sounds like they may be broken loose inside and blocking coolant flow.
3; The New Thermostat you installed should be set no higher then 185 degrees.
Can Get boiling/flushing compound at any good parts store, powered compound I've found to work better.
Note; Remove radiator cap (Engine cool) start engine, do you smell or see oil? Head gasket if you smell exhaust, transmission cooler lines in radiator if you see pinkish oil and/or foam on cap.

Sounds like there's air in the system that needs to be purged...those cars are tricky to do since they have a reverse flow cooling system and air can get trapped in the back of the heads...may take a few tries to get all the air out. There should be a bleeder screw in the t-stat housing and in one of the coolant lines that you need to open up with the car cool and radiator full until only coolant flows out..top off the rad and overflow jar, start the car and watch the coolant level...top off if it goes down and repeat bleeding procedure. May be a good idea to get a shop manual with detailed instructions.
Here's a link to another forum with tips.

It is some sort of a restricted flow. ckeck the radiator, and the heater core. try to flush them out using a water hose. if it is all brown and crappy you will need to have it flushed out by a shop.
Your thermostat could be the wrong one check with an auto shop for the right temp.
Good Luck

This problem can also be caused by a bad head gasket, cracked head or cracked cylinder block. I would have the cooling system pressure tested for any of the afor mentioned problems.

Clogged water jacket,leave radiator cap loose locked on the radiator but loose so pressure can escape,until it's fixed,it wont get so hot with out being pressurized

Could be that you have a collapsed interior wall of one of your radiator hoses or a clogged by pass hose.
