1997 Chrysler Concorde 3.5 tries to run hot. Over flows to jug

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

    Yes, both head gaskets were replaced. Could the new parts be faulty?

SOURCE: oil leak on 95 chrysler concorde. 3.5

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).

SOURCE: how do you replace the egr valve in a 1997

Chrysler Concorde 1993-1997 3.5L MFI 6cyl
Exhaust Gas Recirculation System
Operation

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

  1. Check the condition of all of the EGR system hoses and tubes for leaks, hardening or kinks on the rubber hoses. Repair and correct these conditions before proceeding any testing.
  2. Be sure that the hoses at both of the EGR valve and EGR valve control are connected to the proper fittings.
  3. Be sure the electrical connector is firmly attached at the valve control.
  4. To check the EGR system operation, connect the DRB III scan tool or equivalent to the 16-way data link connector. The data link connector is located on the lower edge of the instrument panel near the steering column. Follow the scan tool instructions.
  5. After checking the system with the DRB III scan tool, proceed to the EGR valve leak and control tests, then repair as necessary.

Loosen, but do not remove, the EGR tube to intake manifold screws

The EGR valve attaches to the rear of the right cylinder head.
  1. Remove the vacuum tube from the electric EGR transducer solenoid. Inspect the vacuum lines for cracking, poor seal due to hardness, or other problems. Replace with new hoses if necessary.
  2. Remove the electrical connector from the solenoid.
  3. Slide the transducer up and out of the mounting bracket.
  4. Loosen, but do not remove, the EGR tube to the intake manifold screws.
  5. Remove the EGR tube lower screws at the valve.
  6. Remove the EGR valve and transducer.
  7. Clean both gasket surfaces and check for any signs of leakage or cracks. Replace the components if any such damage is found or if the valve fails the tests.

To install:
  1. Loosely install the EGR valve and a new gasket onto the cylinder head.
  2. Using a new gasket, attach the EGR tube to the valve and tighten the screws to 95 inch lbs. (11 Nm).
  3. Tighten the EGR tube to the intake manifold plenum screws to 16 ft. lbs. (22 Nm).
  4. Tighten the EGR valve to the cylinder head screws to 16 ft. lbs. (22 Nm).
  5. Reconnect the transducer solenoid to the vacuum fitting on the manifold.
  6. Slide the transducer into the bracket.
  7. Reconnect the vacuum lines and electrical wires to the EGR transducer.

SOURCE: My 2001 chrysler concorde 2.7L started running

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.

SOURCE: 1999 vw passat overheating coolant boiling in

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.

I have a 2004 Chrysler Sebring and it is running hot I have replaced the thermostat 10 times and it stills run hot no leak from the radiator but it bubbles back out ouf the intake jug


Take the car to a mechanic and have the coolant tested for hydrocarbons. A constantly overheating vehicle may often have a blown head gasket that causes hot gases to overheat the coolant.

1997 Chrysler concorde LX 3.5 Put water in reservoir and it came pouring out under the middle of engine and now car won't start...Radiator is fine so...Any clues as to why or what is wrong with it?


You say the head gaskets are fine, yet the compression is not.
How do you know the gaskets are not blown ?
Normally, when an engine runs hot, the gaskets expand and cannot contract, and the heads warp so they are not flat. You loose compression and usually have coolant in the cylinders.
You can also loose compression but not have coolant leaking into the block. It depends on what warped.

IT is overheating.I have already replased the thermostat,&waterpump.Both electric fans are working fine.Replased overflow pressure tank.still overheats within 30 min of run time.Did compression...


you probably have either the 3.2 or the 3.5 v-6. as 15 years as a chrysler tech, i would say you need a minimum of head gaskets replaced. compression is very low. but remember this, the heads have to be checked for flatness, and if they are warped over 6 thousandths they will have to be replaced.

My 1997 honda accord is starting to get hot. My husband just changed the radiator. Just wondering what could be wrong?


Thermostat is clogging, water pump failure, air in cooling system, a leak in the hose. These are the obvious issues concerning overheating. Hopefully its not a blown head gasket. There is a 30 dollar diagnostic you can have run and the mechanic will tell you if its a blown head gasket. I should know. I have a bmw and i didnt get diagnostic and bam head gasket was way warped. Cost me 2200 for head gasket repair. This is what I recommend you do. Also you could run vehicle without thermostat and see what happens. if it dont over heat then it was thermostat.

Car is running hot. I think the water pump is bad. The upper hose is under a great deal of pressure.


Even a pump with failed seals and bearings will move coolant (will be noisy and leak though) Your problem sounds more like another problem, either the cooling fans are not coming on, you have a bad thermostat, plugged radiator or bad head gasket. If fans are OK, change thermostat and re-test for other problems.
