I am not happy with my new 2015 F-350 4X4 Diesel Lariat.


My last truck was a 2007 F-350 4X4 Diesel Lariat so I am well aware of the heating characteristics of a diesel.

It is now in the shop for a second time and I have not reached my first oil change.

I have the best warranty plan coverage offered

The first time was for heat, or lack there of. It takes forever for the climate control to turn the fan on and when it does the heat is luke warm.

The engine coolant gauge on cold days never really gets to the middle of the normal operating range.

It is now back in the shop and been there for three days for a check engine light, the heat problem again, and the back up sensors on cold days gives false obstruction alarms.

Anyone else having heating problems, it is cold here 2 degrees today. The truck is miserable to be in.

I have the remote start set for 15 minutes and it is always plugged in







Been a member for a long time and have attached pictures in the past, for some reason I cannot any more. I had to code HTML to post these??????????

 

get the tool to measure your coolant/water ratio........could be as simple as not enough water in the coolant....most are 50/50 mix...but once I had a new ford with almost pure coolant....it would not produce heat and during hot day operation the valves would rattle....had the dealer service the coolant and checked it before I left and after that everything heat wise was fine.

 

Calling the dealer right now.

 

Sounds to me like the thermostat is stuck open. That's sounds to simple though.

 

That should have zero to do with heat output. More than not they removed the air bubble that was restricting heat.

 

No idea why you're having trouble with the pictures, what's it doing when you press the image button?

Definitely sounds like a thermostat problem to me, what has your dealer told you about it?

 

try getting heat out of a cooling system with no or low water ratio in it.

Again your responses make no sense. 90/10 coolant/water in my truck and the heat will blast you out in 10 min of running. 100 deg plus air. if your coolant is at 180 deg, that is 180 degrees available for the heater core to transfer heat.

 

That is what I told the "service writer the first time I brought it is. Who knows if it was passed on to the tech.


I agree I hope the dealership looks at it, they have called in the region "Expert to look at it.


I cannot attach photos, just us links




You are correct, if the ratio is incorrect the coolant has trouble transferring heat from the block to the coolant. The correct mixer is 50/50 and the protection should be about -32 with that ratio.

 

He is correct, the correct mixture is 50/50. the heat transference in a mixture greater that that is not idea. You should correct your mixture to 50/50 or you will have hot spots in the block.

 

I can not relate to your heat issue as i have a gas rig but can relate to false signal from the back up sensors. Please post what they did to resolve your issues.
Thanks

 

If coolant is 180 degrees, it is 180 degrees. What type of fluid is 180 degrees matters not. Thermodynamics is a pretty solid science. If that 180 degree fluid cannot reach the heatecore it cannot transfer heat. So you are saying a liquid coolant cannot transfer heat unless it has water in it? Explain my lawn equipment that runs pure glycol and reaches operation temp then. Or any number of non-water based coolants on the market.

 

Your heater problem could be a partially blocked heater core or heater control valve not opening (I'm assuming there is one).

 

I do not want to get into a big argument here on 50/50 mix. Here is a suggestion, don't believe me, Google "why 50/50 mix" and read the reasons yourself. You are not doing your engine any favors by running a 90/10 mix.



I do not believe the problem is in the heating system or the climate control system.

I think the key is the temperature gauge never quite reaches the middle of the normal range and it takes forever for it to get there.

The dealer has now had the truck for four days.

 

Will do.......
