Noise like chain after coolant hose replacement
Sorry if I goof up something as I'm new to the forums today. Anyway, I have a new sound from my 2010 F350 6.4 diesel this morning when I started it for the first time. I'm in Arizona so it was about 70 degrees out this morning. It sounded like the same noise when you pick up a chain. It went away after about 4 minutes.
Also, the other night I thought the engine made a lot more of what I call pings (hear it on many cars but, just not like this on mine) than usual after I turned the vehicle off. There was a faint smell like something hot too but, I thought it was to faint and just road crap (plastic bags, etc). I just replaced a lower radiator hose. It is the half that is connected to the engine. Did it myself since the dealership wanted $625 to do two hoses.........I was like, seriously?
I have checked all the fluids and everything is full or at the correct level. I haven't checked nitrates yet (waiting on the kit from acu strip).
So, I don't know whether the oddities and the hose change are related. I guess I am just trying to catch something going wrong before it becomes to much damage and money, either of which I have time for.
If I were a guessing mechanic..........the water pump isn't working. I've heard similar sounds when other vehicle water pumps go out. But then, why wouldn't my temperature gauge indicate it? To many short drives for it to show up (20 miles or less)?
I would appreciate any suggestions since this is my first diesel, first problem and can't really find anything concrete.
