    I just got a v plow installed and never had problems out of this truck. Took truck and plow home and now the truck is over heating and starting is inconsistent this is all without the plow on it. ANy ideas would help before I take it to the mechanic to look it all over

    Very common to run hotter with plow on because your blocking airflow into radiator. First step is to try driving with the plow in a lower position. Sometimes this isn't enough.

    Use the "Search" feature when your logged in & search for "overheating". You'll find numerous threads on this topic.

    Here's one to start with:

    You can try various things from installing a different fan clutch to the more extreme such as aftermarket electric radiator pusher fan.

    Not sure what you mean by starting issues. You'd have to explain more.

    Good luck.

    How hot is too hot?
    Angle the blade for more airflow
    It may start alot harder when it is hot.

    In his original post he says it is overheating when the plow is NOT on the truck. Is it possible that you overheated the truck when the plow was on and perhaps blown a head gasket?

    Good point Razor.
    Check your coolant levels in your overflow tank as well as uncapping your radiator (when engine is cool of course). It may have spewed out coolant when it became hot with plow on.

    Give us an update Oompa. purplebou
