02 rodeo is leaking water from on top of the manifold


I have a '98 rodeo and had a similar problem. I had to remove the manifold to get to the thermostat housing. A rigid coolant line is connected to the thermostat housing on the aft side of the housing. That rigid line is sealed with a little o-ring that had deteriorated. A lot of work for a small o-ring.

2006 Pacifica 3.5L I have a small coolant leak on the passenger side. The coolant will trickle down and drip from oil pan. The puddle is only 2 inches wide. I did a pressure test at 17PSI and I lost 2PSI...


It is a possibility that the leak may come from bad seals from the water pump or a bad water pump. If you also observe bubble in the coolant inside the radiator when the car is running or water coming out of the exhaust you may have a bad head gasket. The coolant comes out of the bad part of the head gasket near the outside which lets water outside the engine as well.

Leaking coolant but no crack in reservoir or radiator hoses


If it's leaking from center front of engine compartment it's likely to be waterpump. Waterpumps have a small hole called weep hole for early warning when waterpump seal fails leaks coolant into bearing.

1999 buick century, location of the freeze plugs on the heads. once the car warms up there is a coolant leak under the thermostat housing and i am not sure where the leak is.


freeze plugs are normally on the sides of the engines, check to see if hose connected to thermostat housing is not leaking, and also check to see if coolant is coming from the water pump.

Coolant leak behind water pump


No it doesnt. The other end of that pipe is the thermostat housing, it has several bolts holding it to the engine, once removed the pipe will slide out, where you will find a large o-ring where it enters the waterpump. Once you replace the o-ring apply some grease to get it to slide back into the water pump housing without damaging the o-ring.

Dodge intreprid 2002 little oil leak


it could be the little plastic " O " ring that go's on the oil pan plug is deteriorating. this is common with time. if it hasn't been changed wen you have had your oil changed, I always put a little telon tape on the oil plug when I do an oil change just as a precautionary back up. To be 100% sure this is what the problem is you will need to be able to get under the car to check to see if this is indeed where the oil is coming from , as there coud be a leak some where else, for example it could be the valve cover leaking as this is a common thing as well. So as I say you will really need to get underneath the car to be positive.
