OVER HEATING AND NOW THE HEATER DON'T WORK

[dunecrazy]

I PULLED MY 24' TRAVEL TRAILER AND FOR SOME REASON IT STARTED GETTING HOT,ESPECIALLY WHEN GOING UP HILLS.I TRIED TO TURN THE HEATER ON AT THE SAME TIME AND IT WOULD BLOW OUT COLD AIR MOST OF THE TIME.I THOUGHT IT WAS JUST THE THERMOSTAT STUCK CLOSED BUT THE UPPER RAIDIATOR HOSE IS HOT LIKE WATER IS FLOWING.ANY INPUT WOULD BE GREAT BECAUSE I HAVE NO CLUE WHAT TO DO?


04 F350 4X4 6.0
110,000mi.

Had a problem similar to yours while towing, mine ended up being dirty radiator fins, for some reason they seem to be filled with bug guts, this cause low air flow across the radiator and intercooler quick trip to the local car wash was remedy for me

I DO HAVE ALOT OF BUGS AND DIRT,BUT WOULD THAT CAUSE THE HEATER TO NOT WORK?

I think your caps lock key is stuck.

The heater blowing cold on a 6.0 is usually meaning low coolant...

[dunecrazy]

what is the caps lock key?my coolant resevoir is full.

[chuckles]

is there any sign of white crusty deposits around the reservoir?

[POWERED SPARKLESS]

Start out small what is your coolant level at? If you are just a little bit low you won't get hot air, and if you are low DON'T add anything other than Ford's Premium Gold coolant in you 6.0. As said above do you have crusty stuff around your reserve bottle? How many miles do you have?

I got 110,000mi. There is some white resedue on top of the reservoir,but wouldn't that be from the coolant getting so hot?I put on a new thermostat and put in new coolant but heater still dont blow hot air and it is still getting hot.I will clean the fins on my radiator in the morning,that might help the overheating but I dont think that would do any thing for my heater.In the last year and a half while it was still under waranty i had to replace the coolant reservoir,cap,oil cooler,#1,#5,#6 fuel injectors,both head gaskets,water pump,fan blade,fan clutch,radiator,and high pressure oil pump!!!!All of this happend when I was running a diablo sport programer.Since I put on the banks 6 gun this is the first problem I have had.
