coolant leaking from the back of the motor.Took the piece off,I can see the flywheel,coolant is leaking from somewhere back up in there. It,s not the heater hoses.It leaks with or without the motor running. Are there freeze plugs or seals back there?

There is a pipe under the intake and a few places on the intake that those can leak.


We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Chrysler Concorde/Dodge Intrepid Coolant Leak – 2.7L (1998-2004)
CONDITION: A severe coolant leak from the water pump’s weep holes causes the coolant to destroy the
pump‘s bearing, as well as leak into the engine’s oiling system. Catastrophic engine failure can result.
CAUSE: This engine’s water pump is buried beneath the timing cover since it is internally driven off the
engine’s timing chain. Since the front of the pump has direct contact with the engine’s oiling system, the
weep holes have been rerouted. Leaking coolant is channeled back through the pump and into the
engine block. Therefore, if the water pump seal fails, the noticeable leaks will occur as coolant exits the left
side of the engine block just below the thermostat housing and, if severe enough, from the rear of the
engine block, towards the top.

CORRECTION: Be aware of the potential leak points and do not ignore the signs of a leak. It also is
recommended that the water pump be changed whenever servicing the timing chain and/or internal
timing components.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

The water pump is out,it looks fine. I did have water out of the seep hole near the thermostat before. The water running out the back of the engine. There is no water in the oil or oil in the water. If it's not the water pump then what?

Again - don't wait and get help to find the source if need be. Pressure testing, mirrors after things are clean may show just where. When found and known by you or with help then you can decide if you have to ability and tools to fix it or get it fixed. It could easily cost you your whole engine!
