ok so have heat on high and all a sudden itll blow cold ill turn it off wait a lil bit turn it on itll be hot again can do this for awhile
and then I have no heat coming from the bottom vents my feet are freezing and then when I shut the truck off made a goofy sound and the degas bottle was leaking a lil its been leaking I got a new one and new cap ordered is the bottle the only problem ???

 

Is this on a Ford or Chevy??

 

If its ford - I just went thru that I have arp head studs so turns I had a cracked head - right before Xmas too sob so in go new heads with some fire rings that hurt the credit card


Note - I bought the truck with head studs done dont know why they didn't do heads at same time

 

Where did you get heads?

 

My shop out sourced that they use a guy who builds heads for racing engines - dagger diesel performance in Calgary alberta Canada is the shop and only shop ill use

 

yes its a 04 6.0 changed coolant and leaked out so its a tad low on coolant but enough to tun it and still no heat

 

Did you use new thermostat? Is the hose connected to control your heat hose coolant flow? I would see if heater hoses getting warm and make sure the air pump to control blend door is working. Would also check if controls functioning properly and not going into default?

 

well if its not taken care of soon is it gonna hurt anything i can go with out heat i have a 3 min drive to school and in heating air condition class right now going for diesel tech so i can get it taken care of in class for free
also got the new 4in exhaust installed intake elbow cold air intake and sct chip just keeping it on trans tune for now but truck is making a weird sound idk how to describe it kinda like a low whine i guess siunds like coming from engine bay not from the exhaust

als my sct has the ficm voltage gauge what should my voltage be at??

 

If it was going to default he would have defrost and heat comming off that - yes it can hurt your engine if head gasket or heads or gone eventually cook your block = new engine
