YEAR MAKE AND MODEL IS ALWAYS A PLUS BUT ... ARE THE COOLING FANS COMING ON ? IS THE COOLANT CIRCULATING IF NOT POSSIBLY IMPELLER ON WATER PUMP IS BRKOEN FREE FROM THE SHAFT OR RUSTED OFF AND INEFFECTIVE. IS THE RADIATOR PLUGGED UP FROM CORROSION OR STOP LEAK. HEAD GASKET COULD BE LETTING COMBUSTION GASES INTO COOLING SYSTEM.

I've just gotten a 1987 Toyota Corolla and when I run it until it's warmed up, the lower return hose stays cold to the touch while the upper hose gets too hot to touch. Shouldn't both be hot?

indicates a blocked radiator
The fix is a new radiator
no-- it is not a problem thermostat as the top hose will not get hot if the water is not flowing through the thermostat
yes the bottom hose will get hot but will always be 10-15 degrees cooler than the top hose because the water is being cooled down by the heat exchange from the fins of the radiator
If you switch the engine off the the bottom hose will get hotter to equal the top hose as there is no water circulation from the pump

Runs hot sometimes. Top radiator hose hot, bottom cold. What's wrong?

top hose should be hot, all water from engine goes through upper hose, then radiator to cool and out lower hose.

New thermostat, fan switch , fan comes on, still overheats . Upper hose hot, same lower hose but both are hard feels like the water is not circulating . Bad water pump, or head gasket ?

Most likely pump. Head gasket will usually put hot gases into the cooling system and will appear as bubbles in the cooling fluid container. It may also feed lubrication oil into the coolant. The coolant pump is driven by fan belts. Make sure you are not missing any belts.

Engine overheat and no heat

Maybe your radiator is clogged.

Car overheats new radiator 2 t stats diffrent eng new water pump, had same problem with first motor cust cooked first motor filled cooling system with radicat plus overheats sitting in shop heats up real...

Okay sounds like you have a clog within the system, first of all, drain the whole cooling system, run clean water thought the top of the radiator, look to see when the water comes out nice clear, replace the lower hose if you have a petcock close that, refill the top of the radiator, until it is full, start the engine, with engine running turn your heater, let the car warm a little, then reopen the petcock or loosen the lower hose and let the water draw out a little until is pouring out nice and fast, then re-close the petcock and stop the engine.
try and get 40% of the water out, and replace it with 50/50 antifreeze fill to the right point of the cars specs.

2002 Jetta 1.8T blew 40A cooling fan fuse - overheated, destroyed 4 way cooling hose connector - replaced all- now it still runs very hot, inside temp reads 190 (but temp is much higher), cooling fans run...

Then replace the thermostat, because if on lower hose not hot and on upper hose scalding hot = antifreeze flow blocked by the thermostat wich remains closed!!!

Car was not running hot but all at once car poured water out bottom of car could broken therm cause this or water pump or what could br other things wrong

If it really poured out , I would say a hose split. Either the upper or lower rad hose , or a heater hose.
The thermostat is inside a metal housing , so not likely. Water pump would be a slower leak.
A cracked expansion bottle might leak fast , but only a couple of litres. I suggest filling up cooling system , and physically looking for the leak.

Overheating

possibly the water pump is not moving the water fast enough at lower rpms when you down shift the rpms are faster and the pump might be pushing the antifreeze around better
