2008 780 D13, coolant flushed and refill, now heater not working. Bleed or something?

Find out where the coolant or water is going, take a oil sample to see if fuel or water is getting into oil, leave a tarp under truck and run it at hi idle for a time to see if any water is leaking when eng. gets hot enough for the rad. fan to come on?

 

99% the diesel in the cooling system is coming from cups probably soon you're going to have a hard time starting the truck in the morning possible might need an injector or two

 

It happens I always say it's the cost of the truck business possible it could affect fuel but what is happening you're cups are letting the fuel from the rail come their the copper or print and in the cooling system one way to tell for sure check you're water separator I should have coolant inside for sure this is not a super expensive fix it cost no more than 1500 maybe 2 k most of the time even less if u do it in a smaller shop but the ones that do it are very hard to find specially for Volvo engine

 

In my opinion I have done cups on Volvo a #### ton of times and everything you're describing is cups I dont thinkbu should waste the money one the separator but it's up to u obviously another 5 days shouldn't be a big deal but it's just going to get a lot worse and when u go to the dealer for this kind of problem they usually replace injectors with it to and then it gets to be extremely expensive I've actually pulled this cups off with holes straight they the copper between fual rail and coolant. I wouldn't be to worried about the fuel in the cooling system as I would be about the coolant in the piston and after everything is said and done u have to flush out cooling system with restore or dish soap run the truck dump it out and repeat with water till everything gets cleaned up and refill also if u have to replace injector u have to write down calibration code and program into the Ecm for better performance

 

if your leaking fuel in to the water. and you have a water leak. it must be a pretty servere water leak.

i had my truck towed in becuase fuel was leaking into the water. which means overfilling the coolant system. and if ran. blowing out hoses and what not. as the cap didn't release the excess pressure.

also, there are diagnostic charts to go through to pinpoint the fuel into water sympton. advice would be to get it to a dealer or a detroit shop. and get the problem fixed before the engine gets ruined.

as for the heater, if water gets low, the heater quits. don't know what the threshold is. as trucks will hold as much as 15 gallons. but cars only hold 6 quarts. and all it takes to lose heater is 2 quarts loss. that means 1/3 capacity.

 

I am brand new to this forum. I've gotten countless good advise here, but this is my first post. I apologize if this is not the right thread but I couldn't find any other closer to my issue and I cannot post a new one yet. Newby question. I need help identifying these two curved hoses going into the firewall on the passenger side. I believe they are the heater hoses and I do have a small leak at the bottom but I don't know if they carry coolant or remove ambient water, or something else. Engine is Volvo d13 2009, ishift. Thank you all!
