Q&A

I have no leaks that I know of there is no water in the oil. How do I get water in the radiator if it is low?

How did you add the 2 gallons? The radiator has a removable cap on top usually. Do not remove the cap unless the engine is stone cold. The cap holds the coolant under pressure so removing the cap can be hazardous when the coolant is hot. You might consider taking the truck in to be diagnosed

There is no radiateor cap on the top of the radistor, thats why I cannot figure out if the fluid is full. I will make an appointment for next week.

I looked closer at some photos of the 6L diesel and it looks like the coolant reservoir is pressurized, like many European cars have. If you added coolant to the reservoir, that is the same as adding it to the radiator. Sorry for the confusion.

Still I am concerned that you were able to add so much coolant. Has the truck been smoking from the exhaust at all?

No,just a little at start up but expected from a diesal.

Yeah a little black smoke is normal. I've heard a lot about the (liquid cooled) EGR cooler leaking coolant into egr passages so the engine ends up burning coolant. It can look like a head gasket with the white smoke.

There might still be air in your cooling system but I haven't been able to locate a drain and refill procedure for the coolant. Many cars have a bleeder screw that needs to be opened when you fill the cooling system but I can't find anything about that in my manual. When the truck is at operating temperature, feel the heater hoses to make sure both are warm/hot. If one is cold or significantly less warm, you're not getting the coolant flow through the heater core.

Ok I'll feel the hoses when I get to work to see if one is hotter then the other.
