    2001 chrysler PT Cruiser 2.4L
    how can i tell if my 2.4L engine is a Interference engine or not ?

      Officially Chrysler says it is an interference engine. In the real world, it is not possible for valve to piston contact no matter what the belt does, HOWEVER, it is still possible to have valve damage from valve to valve contact which apparently has a lowered risk of happening because for that to happen the sun and the moon and the stars all have to be in perfect alignment, but it is possible and it HAS happened.

    Where is the engine coolant temperature sensor located on a 97 chrysler sebring 2.5 coupe
    Car does not start on cold mornings but starts up great and runs great when weather warms up
     
    • HouseCallAuto
      12/26/2013 HouseCallAuto
      The coolant temp sensor is an inch or two next to the coolant fill neck. If you have a scan tool that reads engine temperature you could simply hook it up and confirm that the reading matches the outside temperature of that day, and that confirms the sensor as good. No need to change it then.

      1. Check the strength of the spark, at the plug end of the plug wires, using an adjustable gap tester. The spark should jump at least a 1/2 inch.

      2. If the spark is weak, remove the distributor cap and check the spark at the coil tower in the distributor.

      3. If the spark is weak, replace the distributor.

      Of course you have to check the spark on an overnight cold engine when you are expecting a no start.

    Why wont my car stay running after a jump start? I put a new alternator in a couple months ago. New Battery? Fuel pump?
    I went out to start my car one morning to warm it up because it was around 10 degrees outside. It started like normal but about 15 mins later when I went back out to leave the car sounded like it was barely running and when I tried to back out of driveway it died ...

      Have the charging system; alternator, battery and wiring tested - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. They will run a series of tests for the battery condition and ability to hold a charge - in addition to the charging system condition and voltage / current output.

      So is it possible that a bad battery is my only problem? I didn't know if having a dead battery meant that my new alternator was also bad because its not charging the battery??? Your help and advice is very much appreciated by the way.
    • HouseCallAuto

      You need a battery. And especially if the battery is the original (5+ years old) because a battery only lasts 3 to 5 years on average before you have symptoms which can vary. Should have replaced the battery first.

      That did it! Had to remove the bumper to get to the battery. Dumbest thing ever. Why hide the battery like that? Either way thanks for the advice.

    Why does my vehicle have a rough idle and hesitates when I step on the gas.
    The vehicle has 135000 miles. The last tune up (spark plugs and wires) was around 90000 miles. I was stopped at the light when the vehicle began to idle rough and the engine began vibrating. When I pressed on the gas, the vehicle hesitated as if it might loose ...

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.

      Possible Causes of Engine Hesitation or Stumble:

      Dirty fuel injectors (cleaning the injectors often fixes this)
      Dirty air filter (change filter)
      Dirty / clogged fuel filter (change filter)
      Bad MAP (manifold absolute pressure) sensor
      Bad TPS (throttle position) sensor
      Bad or dirty MAF (mass airflow) sensor
      Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
      Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
      Bad gasoline (fuel contaminated with water or too much alcohol)

      Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

      Dirty or worn spark plugs
      Bad plug wires
      Weak ignition coil
      Wet plug wires

    Timing belt broke engine stop running
    I was driving my 2001 Chrysler PT Cruiser Limited 2.4L AND THE TIMING BELT BROKE. how can I tell if the engine is good or not? and if the is good how hard is it to replace the timing belt. thank you,
     
    • HouseCallAuto

      It can go either way on bending valves. The best thing is put a belt on and try to start it. There is another way using a cylinder leakage tester but it is faster cheaper and less of a hassle to just put a belt on and see if it starts and if after changing the belt it has no compression then the head has to come off. This timing belt is only for seasoned people. Do not attempt it unless you have several timing belts that you have done prior on other cars.
    • Jimm
      12/26/2013 Jimm
      Be careful - the 2.4L engine is an interference engine - meaning that if the timing belt breaks during engine operation, major damage may occur - as in the valves will impact the pistons.

      The parts are readily available; try these on-line sources; www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the replacement timing belt kit (Dayco part # WP265K3A
      w/o Bracket; Water Pump Driven by Timing Belt, Interference Engine; Water Pump, Timing Belt, Camshaft Belt Tensioner, Camshaft Belt Idler) from around $112.00 for your vehicle.

    What would cause my car not to start after sitting all night with cold weather in the morning.
    Car starts great in warmer temp.someone told me a sensor may have the car thinking its in warmer weather and not giving it enough fuel when it's cold weather.

      Do you have another key to use. It seems that the transponder in the key is not communicating with the security module. the system referred to as Sentry Key Immobilizer Module (SKIM) will cause what you have happening but it always throws a related code, however, in this case the code may be one that you do not have the appropriate scanner to access. Try another key. I hope you have one.

    Why does my car hesitate/fail to start intermittently.
    intermittent problem in both and cold/warm conditions. DTC:p0335 CKP sensor has been replaced and connections to the PCM are good.
     
    • Jimm
      12/21/2013 Jimm
      A P0335 "check engine light" code could be caused by:
      •Damaged CKP sensor connector
      •Damaged reluctor ring (missing teeth or not turning due to sheared-off keyway)
      •Sensor output open
      •Sensor output shorted to ground
      •Sensor output shorted to voltage
      •Failed crank sensor
      •Broken timing belt
      •Failed PCM

      Possible Solutions
      1.Using a scan tool, check if, when engine is running or cranking, that there is an RPM signal.
      2.If there is no RPM reading, then visually inspect the crank sensor and connector for any damage and repair as necessary. If there is no visible damage, and you have access to a scope, you could check the CKP 5 Volt square wave pattern. If you do not, then, obtain a resistance reading of your crank sensor from a repair manual. (There are so many different types of crank sensors that there's no way to put here which resistance reading is correct). Then check the resistance of the CKP sensor by disconnecting the sensor and measuring resistance of the sensor. (It is best to check resistance readings from the PCM connector. This rules out any wiring problems from the start. But it does require some mechanical skill and shouldn't be performed if you\'re not familiar with automobile electrical systems). Is the sensor within resistance specs?
      3. If not, replace the CKP sensor. If so, recheck resistance reading from the PCM connector. Is the reading still okay?
      4. If not, repair open or short in the wiring to the crank sensor and re-check. If the reading is okay, the problem is intermittent or the PCM may be at fault. Try reconnecting and checking for RPM signal again. If there is now an RPM signal, wiggle test the wiring harness to try and induce the fault.

      First step - drain the engine oil. Next, remove the oil filter itself. The oil filter adaptor is held by two bolts and one gasket.

      I put in a gallon of antifreeze this am and it's still over heating. Have not been able to check to see if there's a leak. Where should I look to see if it's just coming out as I put it in.

      There's a leak if you added a gallon. If it's leaking fast you will see a puddle on the ground. Check the hoses and the radiator.

      well could be a few things wrong first a leak check the overflow jug for leaks... check the water pump for leaks or any of the hoses coming off radiator.if there are noleaks here are the possibilities of whats wrong
      -bad water pump will make it over heat
      -bad thermostat will make it over heat and usually will not heat up inside vehicle
      but to me the wy your describing it def sounds like both thermostat is bad and your getting the leak from water pump or any of the hoses

      Possibly the problem is related to; a faulty ignition switch relay - this relay plugs into the relay panel. The problem may also be related to a faulty ignition cylinder (at the key on the steering column).

      Try to run a jumper wire around either of these components (one-at-a-time) to see if you can get the engine to turn off / operate like normal with the key.
      The parts are readily available; try these on-line sources; www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com - to list only a few possibilities.

      I don't think there is an ignition relay. I checked all the relays in the fuse panel. none are labeled as such. I've pretty much ruled out the tumbler and linkage. the fuel pump relay continues to run (obviously). I changed out the computer first. then the ignition switch. it did shut off normally for a while after the pcm replacement. did the the new computer fry? possibly because of somthing else? I dread that there is a wire somewhere that is shorting to another hot getting current back flow.

      I switched all the relays around as a way to test them. I have a parts van junked out in the back forty so parts are no issue.

      after the pcm replacement I drove to the corner store. shut it off went inside and then drove back home. on the way home the service engine light came on and then the engine wouldn't shut off again in the driveway. after killing the engine I decided to replace the ignition switch. no service engine light now during normal driving with new switch. only is on when key is off. no codes either.

      I was thinking that. When it is at idle and the fan is on it puts out a bad smell that goes away when the car starts moving and the fan gets up to speed. It must have something to do with the fan not getting enough power at idle. Would that be your thought?

      Not sure about there being a smell from the blower motor just being delivered lower voltage. I would say no.
