Question about Cars & Trucks
Radiator hose remains cold after vehicle has warmed up. Radiator cap is cold as well. Replace heating lines from front to rear, but those hoses are proper aligned core has fluid flowing smoothly. Car temp is luke warm.
More than likely your thermostat has frozen in the closed position. If you take the neck off of the engine where the main hose goes into the top of the motor, you should see the thermostat. Make sure when you are changing it that you have it facing the right direction and that you clean an properly seal the neck when re-installing it. Hope this helps!

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.

did you use pure antifreeze if so remove it all and add a 50/50 mixture because antifreeze will not heat up good if its pure. needs water to allow good heat.

If the heater core is not damaged or leaking ie: if you don't see coolant on the INSIDE of your windshield or coolant on the floor inside the car then chances are you may just need to BLEED the radiator.
remove radiator cap
Fill coolant resovoir to the cold line if the engine is cold from sitting overnight.
Start engine with cap off
Wait till engine gets hot
While waiting you will see a big gurgle of air bubbles come out and the coolant level will drop
Fill the radiator with more coolant to compensate.
When the fans come on and it stops gurgling air install the radiator cap
You are done
Watch the coolant level for the next few days and top off in the resovoir as needed to keep it filled.
Your heat should be very hot now providing you installed the correct oem thermostat correctly.
Hope this helps

If it is fogging your windows, you have a leaking heater core. Dash removal is required to fix it.
