Question about 1990 Toyota Pickup
I changed out the thermostat and bought a new radiator cap.
Could be a couple places and a pressure tester would help find that. Otherwise Start looking from the top of the engine and work your way down. If i had to take a guess i would have to say intake gasket is leaking.

There are a lot of places the 3vze could be loosing coolant/antifreeze on the back of the engine. Need to get a radiator pressure tester and find out exactly where you are losing coolant/antifreeze to fix the problem.

FILL RAD AND BOTTLE, LEAVE CAP OF AND WATCH WHEN ENGINE IT RUNNING , IF LEVEL DROPS WHEN MOTOR REVS PUMP OK, IF NO CLEAR MOVEMENT PUMP FAULTY, IF BLOWS WATER OUT, POSSIBLE HEAD GASKET OR CRACKED BLOCK/HEAD, YOU CAN DO THIS WHEN COLD,
ALSO CHECK THERMOSTAT IS NOT UPSIDE DOWN AND ALL HOSES CONNECTED ON REBUILD ON CORRECTLY

yes you could change them both yourself if you have the tools,,,and it could be a blowen head gasket or a leaking water hose,,or water pump,,,
first get a new cap,,the cap holds the presher in the rad so the water dont boile up so easly the thermostst may be ok,,,

SOURCE: 93 toyota pick up overheating
I suspect a viscous fan hub fault. It slips excessively and will not draw air through the radiator in sufficient quantities to cool the engine..( That is if you have a viscous hub). Toyota hubs are well known as having insufficient fluid in them to do the job properly. ON mine it was possible to spin the fan backwards while the engine was running. Otherwise check the fan sensors and relays.
