Hey everyone,

I got a question because when my truck is at operating temperature it doesnt blow very hot air. It blows some, but nothing like it should. Truck temp stays right at the right spot, doesnt get too cold and doesnt over heat. Do I have the wrong temperature thrermostat? The truck is from the south so I dont know if they have something in there different. Now its in Vermont and its getting cold!!

K thanks everyone let me know what you think

 

The heater core is probably clogged. You can try back flushing it and see if it helps.

 

Thats where i would start too. I dont see dodge using diff temp sensors diff. areas

 

I would check the heater core like the others said you should be able to feel the hose to see if its hot.If ones hot and the other is not then its the heater core.It could also have a 180 stat.

 

i have somewhat the same problem and ive noticedthat with it on full blast hot its luke warm, but on any other setting lower its hot air. dont know how that happened, but try it, see it the temp changes wth diff. gears.


you say its right in the right spot...well whats the operating temp on it?

mine runs 195 consistantly

 

When the heater core is is somewhat clogged it lets alittle bit of water go passed and when your fan is on high it cools it down too fast for the amount of water going by..I had this happen to me on one of my mustangs

 

so i have a somewhat clogged heater core? im gunna bleed it the right way when i get my manifold back on, and we'll see if that makes a diff. but i can hear some water that sounds to be in the dash when i hit the gas sometimes. but not all the time, maybe 1nce a week ill hear it

 

Where exactly is the heater core? How do you go about unclogging the heater core? My temp is just a little bit to the right of the halfway line on the gauge

 

The heater core is under the dash, pita, but there is a good write up in the DIY section. To flush it just disconnect the hose from the WP and the other one probably has a connection about half way next to the valve cover. Back flush it first, which would be the hose running next to the VC IIRC.

 

Ok I'll take a look at the DIY. Thanks
