HELP brown antifreeze

[danbug1]

antifreeze is a muddy brown color . antifreeze is blowing out cap . i dont know injector cups? is there a way to tell without pulling heads if so how bad are they to replace. truck runs fine and no power loss

sounds like you have water in there.maybe need to get your radiator serviced.

ive seen muddy lookin water in radiators,usaul cause is water.its rust

[danbug1]

ok but what is causing the excess pressure? and it was all of a souden sorry for spelling

[danbug1]

i think i pin pointed the problem. i was unaware of special antifreeze for ps. so im going to flush and refill and see what happens

[Diescipel]

Could be bad head gasket allowing positive oil pressure to push engine oil into coolant. That would explain the excess pressure... hope it's not this!

sounds like just a dirty radiator that has been neglected , due a good flush and use an extended life coolant when filling again ....dont forget the additive as well

problem solved bad thermostat. and brown water was caused from rust from when the motor sat on a shelf for a couple of years
