hi guys New to this forum Been looking through threads and found nothing that relates to my problem I have a 2001 Dodge ram 1500 5.9 And my problem is I have lotta heat an idle But as I start driving it turns to lukewarm and once I go back to idle It'll heat back up I have a new radiator, rad cap 190 thermostat and heater core Any advice or suggestions would be great thank you


this is my normal operating temperature

 

Are you low on coolant? Check it and write back

 

coolant seems to be fine just went and picked up a new thermostat and some coolant

 

97 dodge 5.9L
Engine loses power and sputters after driving for a while. Runs great until this happens. Will do it for a mile or two then be better. Every time this happens, The radio audio cuts out just before. Every time. When the engine stops sputtering the radio audio returns. Any ideas would be greatly appreciated. Tom

Temperature seems fine... low coolant would potentially give a higher temp.

How long ago since you last used the heat?
The seal on the blend door could have deteriorated and caused it to stick shut.

This was the case for me... it took lots for cycling the vent control back and forth to eventually get it to break free.

 

Either coolant isn’t circulating, or your heater core is clogged. Mine was clogged, and I unclogged it by using a compressor, and blowing the crap out of it. Needless to say, I have heat now!

 

i got the truck last year and it had the same heat problem so i replaced the radiator, thermostat, and put a bran new heater core i got really good hot heat for maby one drive after that but then everything went back to like warm and has been there ever since

 

With a 195 i would think the gauge would read higher unless the sender is bad. You might want to look at the temp motor shaft in hvac unit, Could be a blend door problem.

 

ok thank you will look into that
