Why are all radiator hoses hot except the lower hose?
Lower radiator hoses in water cooled engines are return lines. The upper radiator hoses are feed lines of hot engine water to the radiator. The reason that lower hoses are cooler is that the radiator has allowed much of the water's heat to dissipate into the air. Thus, a lower radiator hose contains cooler water than other radiator and heater hose lines.
What will cause the car temperature run hot if you have replaced the radiator and the thermostat?
the hoses leading to and from your radiator might be clogged. If you had a rusty radiator, the rust may have clogged the hoses that carry the coolant. you should check all your hoses and even flush them out.
What causes your car not to heat up?
First you need to make sure it is actually not heating up. Do this by checking to see if the radiator hoses are getting warm after running for 10-15 min. Be careful they could be HOT. If the hoses are hot then the heater core is plugged and will need to be replaced. If hoses do in fact not get hot then the thermostat is most likely stuck open. removing it will tell the tale.
Why isn't the Radiator not getting hot?
The radiator may not be getting hot due to a lack of coolant, a faulty thermostat, air pockets in the cooling system, or a malfunctioning water pump. It is important to check these components to determine the cause of the issue.

Why is the radiator cap not getting hot?
The radiator cap may not be getting hot because it is located in a separate reservoir from the radiator itself. It is designed to maintain pressure within the cooling system and does not directly contact the hot engine coolant.
