Overheating problem

(1999 Honda Civic)
99 honda civic dx 4dr keeps overheating.... i've replaced the thermostat and a leaky hose and recently the fan quit coming on and the lower radiator hose is not even warming up. the top hose is blazing hot however and I even rigged the fan with a switch to see if the fan was the problem and it is not there is about a 140,000 miles on it and i don't believe the water pump and timing belt has been serviced could the pump be the problem???

i would throw out the thermostat and see if the problem persists.the main fan motor in this motor is a problem child - replace it.Also once you overheat the thermostat it is suspect and should be 86ed.

if you upper radiator hose is blazing hot and the lower hose is cold the you should have a blockage in the raditor itself, the thermostat on that engine is placed behind the water outlet since the upper hose is hot the thermostat is working. replace you radiator flush your coolant and you should be good to go
