    Hello all,

    I have a coolant leak coming from the front driver side of the engine, behind the alternator and just above and in front of the oil pan. I think it is the water pump but I just want confirmation.IMG_0194[1].jpgIMG_0195[1].jpg

    Well dig in. I am sure it is either a bad O ring or the plastic cover for the thermostat. Start by draining the system and taking off the intake manifold. Me personally I would replace all the O rings you can at one time because if one goes that means the others are getting old too.
