We have a 2016 Cascadia, DD15, 474000 miles. Smell of
We have a 2016 Cascadia, DD15, 474000 miles. Smell of burning antifreeze, not sweet smell in the cab while the heat is on or vents open. Rear cabin heater core burst while on a mountain under heavy load, and was bypassed. Front heater core begin leaking next, and was replaced. Radiator cap began to seep. Obviously, we have excess pressure in the system. One box required replacement, and EGR cooler was "burned through", and hence, replaced at dealer as well. In less than 8k miles, the problem is apparent again. Smell is heavy in the cabin with the vent open. Mild smell while in A/C mode. Engine power seems to fluctuate, and rumbles loudly under load now. Was quite before this trouble. Also, economy drops dramatically. … read more

Do you know a lot about a Kubota l4350? L4350... don't know
I am now . . . mechanic gave up!

Now, after starting up with filter glass full of fuel, the glass drains in about 20 seconds . .. more fuel drawn off than resupplied . . . and then stalls. Re-bleed line, fill glass . . . does it again. What next? … read more

1997 Cummins 8.3 running hot, The motor is in a garbage
The motor is in a garbage truck. It normally runs at about 195-200. The last week or two it starts to climb over 220. If you are driving from stop to stop for several hrs it stays around normal. But if you start to drive farther distance it starts to go up. When we go to the landfill it will get real close to the red line and if you let off the throttle to idle it will drop down but not to 200. We have replaced the coolant sensor and that didnt fix it. It is the original radiator. The coolant has been changed with the coolant filter since the truck was new. My mechanic thinks I need a new radiator. The fins are clean so there is no dirt or bugs obstructing air flow … read more
