its one thing after another with this dam truck!
i have replaced thermostat and flushed heatercore,still no heat in cab. it comes out hot at first then cools off real quick, the engine is staying at 180, the blower works fine, i just dont know what else it could be?! any suggestions?

 

Try lighting the seat on fire that'll warm yu up.
Have u checked to see if the ducts have blockage or maybe even a break in them .

 

heat will blow out of the ducts for a min then get cold. the air is blowing, just not warm. if i turn the heater off for like 5 minutes, then back on, the air will be warm but only for a min. if i rev up the engine i can hear like bubbley sound from the heater core but its not leaking anywhere.

 

ive never experienced a bubly sound. is there air trapped in there?

 

If the coolant end of things is good, then perhaps a blend dorr or vacuum servo is bad.

You can switch from defrost to vent to floor, etc with no problem? If you're on vent, it stays on vent? Does it ever fade off or switch seetings on it's own?


Good luck with your ride.

 

all the swtiches work great, stay at the setting i have them on. everything seems to work great. just no heat. i have even put cardboard infront of the radiator to make the enigne run hotter and still nothing, im ready to tear my dash apart with a prybar and a 3 pound sledge hammer!

 

right mixture, make sure no air in system at all, change thermostat in case its gettin stuck open. post this in all forums some motorhead has got tobe able to help

 

how would i go about getting air out of the system?

 

im not sure with dodges but some cars have a bleeder screw that you open and the air wheezes out .if it doesnt run it check the fluid levelin radiator the air should go to the highest point after a couple of runs. keep adding to the radiator untill its full and doesnt change

 

Are you using a 50/50 mix of coolant to water? You're positive that the heater core is not blocked? Did you change your water pump at all? Perhaps your thermostat is malfunctioning. They can be bad right out of the box.........

No chance air is trapped?

Sounds like everyone is stumped.....lol. Are you losing coolant at all?


Keep up posted


Good luck with your ride.
