Hi, first examine the thermostat housing very closely and make sure it isn't leaking there. Also squeeze on the radiator hose to make sure you haven't got a pin-hole in it somewhere and that it's also not leaking where it is clamped to the thermostat housing. If you find nothing there check that all of the intake manifold bolts are tight.Hope this helps. John

Bad water leak probably heater coil


Sometimes, not the heater coil...this leak usually smells inside the cabin...can you see anti-freeze build up anywhere? These motors are more prone to a water pump leak (needs replaced, inexpensive and not to difficult) or the intake manifold gasket...more costly about $400. for a mechanic to do...you should see some anti-freeze build up around the intake bolts...this assumes that there is no water in your oil...which is far more costly as this indicates an internal cylinder head leak...Could be just a hose leak...a bad radiator cap...or thermostat housing leak, (maybe a cracked housing? Help me help you...do you see any anti-freeze build up anywhere? Hope this helps.

Oil in water circuit


oil in water is usually caused by bad intake gaskets. if the intake leaks, it will let oil in water. anti freeze flows in intake, if gasket is bad it will drain down inside of engine to the oil. good-day ! you may also see a anti freeze leak around outside of intake gasket that mounts to engine. if it is bad enough.

Anti-freeze leaking from either the freeze plug or intake gasket. I need possible solutions. Tone Mac


Without knowing what year or engine size is, I/m just guessing??????? But the 3.1L engines are FAMOUS for intake maniflod gaskets leaking. Look where the intake bolts to the heads. A freeze plug is in the block. Freeze plugs dont leak unless you have been running pure water or weak/cheap anti-freeze. They will rust out from behind and its BIG BUCKS to replace them all.

Leaking anti-freeze from back of motor onto exhaust-where would leak be most likely?


Rear crossover ports on the intake manifold, and/or freeze plugs at the rear of the engine. Also see if there is a hot water control valve for the heater in that area.

Leak below flywheel.


pull off the tranny inspectiont cover and see if its wet in there, if it is its prob the front tranny pump seal if not and it is anti freeze youve go a hose leaking or intake manifold gasket leaking or a head gasket leak!!! either way the 4 wheel drive would have nothing too do with any of the leaks !!!!
