97 dodge ram 1500 Lower heater hose not hot or even very warm at running temp. Truck is seems to be running fine and even has heat. Is this a ploblem?

are you talking about your heater core for heat in the truck ? is there a valve in the heater hose that you have to open to get the hoses hot to the core this is under the hood , follow the hoses , could be clogged core , does it over heat , or get up to temp should be about 190 normal temp for most motors why did you change these parts anyhow , did you use the radiator fix bars leak stuff that you put in , bars leak , if so you may have clogged your core , take the hoses off the core and blow it out ,pain in the but you went this far , ck for that valve to open

Sound like it could be a bad thermostat or maybe low on anti freeze or bad water pump. Does the engine overheat at all?

Do you live in an extremely cold region? If so, those folks usually have a problem with heater in winter time. With a fully warmed up engine, how hot does it get in degrees F? Are the heater hoses hot?

You probably have a plugged heater core. If one hose is hot, and other one is quite a bit cooler or cooler, then you have a problem with flow through heater core. Try flushing it. I hope that will help.

Good Luck!

You probably have a restricted heater core. Buy a can of radiator flush and follow the directions on the can. If this doesn't work, then take both heater hoses loose at the engine an run water thru the heater hose with a garden hose. Hopefully this will clear the restriction. Hope this helps :)

check to see if both heater hoses are same temp when engine is at normal running temp if not heater core not flowing coolant may need to flush also make sure it does reach normal temp around 200

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.

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.

dodge tends to run at about 200dg. i have a 97 with a 318 and this hs been its normal temp since it was new . if it is truly over heating and if the warepump is bad you shoul see water leaking from the bottom of pump . hope this is helpfull
