Question about 1991 Ford F150
Just changed hoses and thermostat, and flushed radiator. Ran for 2 hrs and the bottom hose is still cold. Whats up with that? It was doing that before I changed everything, could it be a bad water pump?
Could be you fitted the thermostat in the wrong way around ,or the plastic impeller on the water pump with a steel drive shaft has failed they end up with the drive shaft spinning but the impeller is not turning ,go for the thermostat first though .

I have a 1991 Ford Ranger 2.9,and I am having a heat problem I did change the thermostat but no heat yet,this is what I found so far. I checked top radiator and its hot,the bottom hose on radiator is cold. the 2 hoses running to the heater core are hot. I do not see a weep hole on the water pump but I am not loosing any antifreeze. Could the water pump be shot? or could it be the Temp.Sender unit? I do not think it is the blend door. i did look at the heater core no leaks that i could see. any other thought? please help I need heat soon.

the open pipe that you took the hose off of is the thermostat housing, you will need to remove this to reveal the thermostat, make sure you use a new gasket with sealant when reinstalling thermostat housing to prevent leaks and dont over tighten the bolts,run both bolts down as far as you can before final tightning

It's normal for some fluid to be forced into the reservoir during operation due to fluid expansion and pressure. Usually the fluid in the reservoir will increase or decrease depending on what temperature the engine is at. Unless your truck is overheating I woudn't worry too much; just make sure the fluid level doesn't get too low or too high in the reservoir. If it is running hotter than normal and excessive amounts of fluid are being forced in to the reservoir you might have a blown head gasket. As far as the hoses collapsing; I have a 2001 Ford ranger 4.0 V6 and I noticed that the top radiator hose appeared to be collapsing in one of its bends. I installed a radiator clamp on the hose at that spot just to keep it round and from pinching itself off. It probably happens from the heat; just keep an eye on it. It may be that your hoses need replacing; I know mine did the same thing after just having been installed brand new though. God bless you and I hope everything works out for the best!!! : )

follow the upper hose to the housing it goes to and if you see bolts there the thermostat should be under it. make sure to have coolant on hand as you will loose some.
