Question about Cars & Trucks
Possibly needs a new water pump, either that or you have a blockage in the radiator,. Make certain you didn't put the thermostat in back to front. Take the thermostat out altogether and try it.

I answered the other question you placed but you have airlock problems or the rad is blocked. Again, you don't say make model year mileage etc. If its been run for any significant period without antifreeze / summer coolant then the rad is blocked with dissimilar metal debris / crud.

1. blocked radiator core
2. blown head gasket
3. cracked head
4. water pump
These would be the major problems causing the overheating.
Timing could be another but unless the timing has been changed recently it is most probably one of the causes

it is the head gasket blown from the cyl to the water jacket ,a radiator specialist can test for combustion gases in the water to confirm this ,but that is what it is . "youdoit"

Testimonial: "compression test ok still looking"
SOURCE: Radiator problems
it may be a little off, but the lower water hose seldom gets very hot,, as its this hose that suplyes the engine with ""cold water"" the hot water comes out the top hose,, drains down the rad and cools on the way down then enters the engine through the bottom hose """if your engine stayes running in the normal place on the gage,,,and not over heating""" why are you spending money for nothing???""
you wont get the bottom hose to run hot unless the engine is cooking

Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.
