I took my new to me 11 2500HD to the stealership because it's using coolant and it has the infamous oil pump whine. Now I ALWAYS do my own work. The thought of someone else wrenching on my stuff makes me loose sleep but it's a major cost if it's head gaskets and it's still under warranty so....I guess I'll loose some sleep and save some money.
It all started with a low coolant light coming on in the morning then going out after the temps come up. Then after a few days of that it would come on and stay on. So I would pop the hood and add about half a gallon. I put my cooling system pressure tester on it and it will loose about 5psi over a 20 minute time span, showing no external leak. I take it to the dealer and tell them the story and they do the same test and have the same results. They call and tell me that it is losing coolant but for them to find out if it is a head gasket, they need to pull the glow plugs, pressurise the cooling system then turn it over to see if coolant sprays from the holes. "BUT.... if it doesn't spray out the holes the there will be a charge for the work" I said "what!? Your telling me that the coolant is going somewhere, and your going to charge me to find out where but the repair is covered under warranty?"
Then we talk about the oil pump whine PIP 4898. He says that the noise I am hearing is not that of the oil pump. I told him the noise comes and goes and varies in intensity and maybe it's not doing it right at the moment but when it does there is no doubt that it IS the oil pump whine. There are a hundred videos on the web of this noise and mine sounds EXACTLY LIKE IT. The day I got the truck I noticed it and googled whining noise lml and found all the people with the same problem, a tsb on the matter and videos of it. I told him to keep trying cause it's there more often then not.
We will see what tomorrow brings after the glow plugs test.
