well i finally had to turn the heat on the other morning got a bit cool. but my heater does not blow hot air just warm air heater hoses are warm on both sides dont know if its just cause i have a water cooled turbo or not but i am thinking the blend door is messed up i am really not sure on this one anyone got any ideas on what to check

 

check the thermostat...

 

Is the hose to the heater core hot?

Im thinking its probably the heater core. Not a fun job - dash has to come out. Mine could probably be replaced but I wouldnt consider tackling that until I absolutely had to.

 

 

Be a good idea to replace all the coolant hoses along with the coolant?? That's if they never been done??

 

if you **** i recon

 

Saying that, cause it's more logical with the coolant drained, your in the garage/shop/driveway, basically at home and not on the side of the road with a blown hose. What's another $70 in hoses compared to say, a damaged engine?? If you can't tell, I'm big on maintenance.

 

the thermostat is new or not that old and the coolent is only 3 months old i did not replace the hoses though. i hope its not the heater core i have donr one in a dodge and that was enofugh for me

 

What kind of thermostat?

I would really recommend one from Cummins. I have seen many have trouble with cheapy parts store thermostats in these beasts.

 

may be the wrong tstat they are rated for different temps
