A cover plate on the front of the engine may develop a coolant leak, resulting in an engine overheating condition. This plate covers the location where the water pump was installed on previous versions for this engine. Replacing the gasket for the cover plate and refilling the cooling system is generally all that is required to correct this concern.

    when my coolant was low or out. my heater stoped working after the gauge got to 210. so a couple of days ago i put more coolant in. also my truck is not starting on the first try then the secend it takes it a few to start then when it dose it is really shaky at first. when i speed up i hear this noise from the passanger side of the truck which sound like gas, or the coolant is having problem geting through or some thing. one last thing when i speed up my truck seems to shift really hard.

    I've been have issue as others with funny coolant sounds on passenger side. Blew the gasket on my water pump cover gasket. I hope everything else is ok...
