6.4 drinking coolant???

[younggun55]

Well my dad was pulling about 8k in his truck with the spartan 150 this weekend and he said it started to make a really weird whining sound about 5 min from home so when he got home he popped the hood and was dry on coolant. He parked it since then so I went and through his dpf back on for him and pulled codes today but not sure what it is. Got P0703, P0529, and P1000. He said it wasn't dumping any white smoke and its not leaking in any noticeable locations so idk its a job 1 but has already had the rad replaced and the venturi installed. Any possible ideas? Going to ford sometime this week I guess.

P0529 Fan Speed Sensor Circuit Intermittent, P0703 Brake Switch B Input Circuit, P1000 On-Board Diagnostic (OBD) Systems Readiness Test Not Complete. Some of the leaks are not that noticeable. Some guys have the leak dripping on the in inner part of the frame rail, so it doesn't really drip. Was there any loss in power? None of those codes relate to the coolant directly. Perhaps cracked EGR cooler, or malfunctioning EGR valve Keep us posted as to what they find

I had a blown head gasket...

[younggun55]

what symptoms did you have when your gaskets went on this truck and do you remember what codes you were able to pull?

[Bassline32]

no codes, no white smoke or anything. Just tons of coolant spray from the degas bottle cap... She's head studded now.

Whos studs are ready for the 6.4? I didn't know anyone was selling them yet.
