Question about 1997 Chrysler Concorde
My husband replaced a head gasket, waterpump and thermostat. He cranked it up and let it run some. It's still trying to run hot. It boiled into the over flow jug. Thanks in advance, SJ

What you need to do is steam clean engine compartment making sure to cover Distributor/coilpacks with plastic bags to make sure that they stay dry...Do this at a self serve coin wash....Prior to the steam clean spray engine degreaser on oil pan and block from under the vehicle...Once you are satisfied that engine is clean drive vehicle home and park it....Put a big piece of cardboard under vehicle as to locate proximity where leak is coming from(ie; location of drip marks on cardbord to possible places oil could leak...The reason for the cleaning first is because if you have oil all under your vehicle when it heats up it will drip from any where and this method will isolate leak....the most probable places are the pan gasket , drain plug (make sure there is a rubber gasket on plug), valve cover, Distributor( if applicable), oil filter , sending unit, and of course crank, cam seals...Remember that oil leaks are caused by back pressure in the system and more times than not all starts from a vehicle that has been neglected and has clogged pcv valve (positive crankcase ventillation) if you still cant determine where leak is coming from you will have to take it to a repair shop and have them do a die test....make sure it is a shop that you trust cause as you know oil leaks are very frustrating .....Good Luck

SOURCE: 97 chrysler lhs overheats
Head gaskets don't cause overheating Usually they are a result of overheating. If the headgasket is bad one wil get leaking into the cylinders of coolant,which wil show up as milky oil.Like some one else stated ; have the radiator rodded out,(cleaned and fluashed).

Chrysler Concorde 1993-1997 3.5L MFI 6cyl
Exhaust Gas Recirculation System
This system reduces the amount of oxides of nitrogen (NO x ) in the exhaust by allowing a predetermined amount of exhaust gases to recirculate and dilute the incoming fuel/air mixture. The diluted air/fuel mixture reduces peak flame temperature during combustion, which in turn inhibits the production of Nitrogen oxides. The principal components of the system are:
- EGR tube (connects a passage in the intake manifold to the exhaust manifold)
- EGR valve
- Electronic EGR Transducer
- Vacuum hoses
Component and System Testing
Removal & Installation
EGR Valve and Transducer
EGR valve and transducer assembly-3.5 engine
The EGR valve attaches to the back of the cylinder head-3.5L engine
Loosen, but do not remove, the EGR tube to intake manifold screws
The EGR valve attaches to the rear of the right cylinder head.

Is it poping back threw the intake or exhaust? if so it could of jumped time, the massair flow sensor will cause it to run really bad as well. You need to test fuel pressure and replace fuel fliter then try it again if fuel pump pressuer does not pump to 40 PSI and hold for 40 seconds then the check valve in the pump is bad ad you will have to replace the fuel pump and sock. let me know about the back firing first.

Most likely you have a faulty Thermostat. If you know where the thermostat is a quick way to check it is to remove it and see if the problem continues. If not, buy a replacement thermostat and install it and your done. If the problem continues then you have a bigger problem that need a mechanic for diagnoses. The thermostat is usually located on the upper Radiator line where it connects to the motor.
