    Default 1995 blazer enigine trouble

    I am in need of some help with an enigne that seems to be locked up. It is a 4x4 4.3. My wife drove it while it overheated for about an hour. I found a leak in the rad. I replaced it and put new anti-freeze in it. Then two days later it started running ruff then I shut it off and when I went to go trouble shoot it it was locked up. Does anyone know what needs to happen from here. I have a OBII and check the code it came back a P0401. Please help

    Thanks
    Rusty

    If its locked up there isnt much you can do other than replace or rebuild. By locked up I'm guessing that when you try to start it wont crank over?
    First check the oil for water and the water for oil.
    Then remove the sparkplugs and try to turn it over.
    If you have oil and water mixed it could be just a blown head gasket.
    If it wont turn over after removing the spark plugs you've got a siezed engine.
