redtruck65MA...Check that "WATER PUMP" before you do anything else ! Also, check the oil & see if there is any
discoloration (like water / murky) ! Pull a plug on each side
if you think it is a head gasket, check & match the plugs from each side, if one is a different color (brown / wet ) that would
give you an idea if it is a head gasket & if so, which side is
gone! If it is the water pump, get a HD unit to replace the
old one! Had the same problem & replaced the WP with a HD &
it made a world of difference ! Hope this helps....
