Engine overheating due to fan blades rubbing against shroud

I took my chrysler 300 2005 which has only 17000 miles to dealer for oil change lube and tire alignment. 100 miles later the engine started to overheat and warning light came on, I took to another dealer for repair and had to replace both radiator fans and motord. I was told that the fan blades were cracked and rubbing against the shroud so they were not cooling. How could this have just happened by itself?

Engine light came on and car is over heating. Took it to auto zone and was told it's the fan relay. Its a 2003 PT Cruiser, Turbo. I opened the fuse box under hood. There are 3 spots for relays in there...


Turbo Radiator Fan

The radiator cooling fan is a variable speed electric motor driven fan. The radiator fan assembly includes an electric motor, fan blade, and a support shroud that is attached to the radiator. The radiator fan is serviced as an assembly (fan motor/fan/shroud).

The variable speed radiator fan is controlled by the Powertrain Control Module (PCM) by way of a Pulse Width Modulated (PWM) signal. The duty cycle ranges from 30% for low speed operation then ramps-up to 100% for high-speed operation. This fan control system provides infinitely variable fan speeds, allowing for improved fan noise, A/C performance, better engine cooling, and additional vehicle power.

To control radiator fan operation, the PCM looks at inputs from:

Engine coolant temperature
A/C pressure transducer
Ambient temperature
Vehicle speed
Transmission oil temperature (automatic transmission only

HENCE CHECK THE PCM

At 28,066 dealer oil change. At 28,778 dealer flushed engine to remove sludge build up and changed oil. At 30,835 miles inspection, dealer flushed engine to clean out sludge and changed oil. At 34,630...


First dealer was NOT doing you any justice. Next oil change run a can of GUNK engine flush let idle 5-10 mins then change Oil & Filter and use a good oil like Castrol or Valvoline 10w-30. You won't have "supposed" sludge build up.

Service 100 thousands miles


The 04 was pretty straight forward.

Change the oil and filter when the display tells you to. (Don't forget to reset Oil Life system!)
when the display tells you to change engine oil... Do the following as well:
~Lube Chassis Components
~Check Tires for Air and Damage
~Inspect Break System
~Check Engine Fluids and Washer System
~Check Power Steering System
~Check Wiper Blades
~Check Restraint System
~Lube Body Components (See manual)
~Replace Cabin Air Filter (Located in firewall on passenger side.)


Every 25K miles do the following:
~ Inspect Fuel System, Exhaust System, Accessory Drive Belts for damage or wear.
~ Replace Air Cleaner

Ever 50K Miles
~ If used for Towing - Replace Transfer Case Fluid :: If not change fluid ever 75Kk miles.

Every 100k Miles
~ Change Automatic Transmission Fluid and Filter
~ Change Automatic Transmission Fluid and Filter again at 150k if heavy service
~ Replace Spark Plugs

Every 150k miles
~ Change Engine Coolant (Or every 5 years which ever comes first!)
~ Replace Engine Accessory Drive Belt

optional y are supposed to change the transfer case fluid every 50k if towing

How often should i change my oil in my 2008 dodge caliber


If you like your car, change every 2,500 miles. Manufacturers say longer, and that seems to work, but oil change is pretty cheap compared to oil related failures...

    Sensors went bad, at 60 k miles, is this covered in warranty


    you need to take the vehicle to a real mechanic. Jiffy lube employes are not mechanics. Change your oil at jiffy lube and get mechanical work done at a reputable auto dealer or mechanic shop.

    Engine overheating on 300c, fan won't turn


    Is it losing coolant? If yes posible weep hole on the water pumpAre the radiator fans switching on? The constantant control module (or similar nomenclature) may not be telling them to come on.
    It's a dumb question, but...are you sure that when you replaced the T-stat you put it in right side up? Spring side toward the engine and you can see the triangular shaped arch before you put the cover on. Fixed that probably a dozen or more times. Those are the inexpensive do it your self fixes.If these don't work or apply. Check and see if the cooling system holds pressure. You can get a loaner at any chain autoparts store.or take your car to the shop and pay fifty or a hundred bucks for the diagnosis.

    Changing the water pump on 2000 Jeep Grand Cherokee V6


    WATER PUMP
    The water pump is bolted directly to the engine timing chain case/cover.

    A gasket is used as a seal between the water pump and timing chain case/cover.

    If water pump is replaced because of bearing/shaft damage, or leaking shaft seal, the mechanical cooling fan assembly should also be inspected. Inspect for fatigue cracks, loose blades, or loose rivets that could have resulted from excessive vibration. Replace fan if any of these conditions are found. Also check condition of the thermal viscous fan drive. Refer to Viscous Fan Drive in this group.

    The water pump can be removed without discharging the air conditioning system (if equipped)

    REMOVAL
    Disconnect negative battery cable from battery.
    Drain cooling system. Refer to Draining Cooling System in this group.
    Do not waste reusable coolant. If solution is clean, drain coolant into a clean container for reuse.

    The thermal viscous fan drive is attached (threaded) to the water pump hub shaft. Remove fan/viscous fan drive assembly from water pump by turning mounting nut counterclockwise as viewed from front. Threads on viscous fan drive are RIGHT HAND. Using special tool spanner wrench 6958 with adapter pins 8346 and a suitable fan wrench loosen the fan drive Viscous Fan and Fan Drive Do not attempt to remove fan/viscous fan drive assembly from vehicle at this time.
    WARNING: CONSTANT TENSION HOSE CLAMPS ARE USED ON MOST COOLING SYSTEM HOSES. WHEN REMOVING OR INSTALLING, USE ONLY TOOLS DESIGNED FOR SERVICING THIS TYPE OF CLAMP, SUCH AS SPECIAL CLAMP TOOL (NUMBER 6094) SNAP-ON CLAMP TOOL (NUMBER HPC-20) MAY BE USED FOR LARGER CLAMPS. ALWAYS WEAR SAFETY GLASSES WHEN SERVICING CONSTANT TENSION CLAMPS.

    CAUTION: A number or letter is stamped into the tongue of constant tension clamps. If replacement is necessary, use only an original equipment clamp with matching number or letter.

    If water pump is being replaced, do not unbolt fan blade assembly from thermal viscous fan drive.
    Remove two fan shroud-to-radiator nuts Fan Shroud Mounting Hardware Do not attempt to remove fan shroud at this time.
    Remove fan shroud and fan blade/viscous fan drive assembly from vehicle as a complete unit.
    After removing fan blade/viscous fan drive assembly, do not place thermal viscous fan drive in horizontal position. If stored horizontally, silicone fluid in viscous fan drive could drain into its bearing assembly and contaminate lubricant.
    Remove accessory drive belt as follows: The drive belt is equipped with a spring loaded automatic belt tensioner. Relax tension from belt by rotating tensioner clockwise (as viewed from front) Automatic Belt Tensioner - When all belt tension has been relaxed, remove accessory drive belt.
    Remove lower radiator hose clamp and remove lower hose at water pump.
    Remove seven water pump mounting bolts and one stud bolt
    CAUTION: Do not pry water pump at timing chain case/cover. The machined surfaces may be damaged resulting in leaks.

    Remove water pump and gasket. Discard gasket.
    INSTALLATION
    Clean gasket mating surfaces.
    Using a new gasket, position water pump and install mounting bolts as shown. Water Pump Installation - Tighten water pump mounting bolts to 54 N·m (40 ft. lbs.) torque.
    Spin water pump to be sure that pump impeller does not rub against timing chain case/cover.
    Connect radiator lower hose to water pump.
    Relax tension from belt tensioner Automatic Belt Tensioner - Install drive belt
    CAUTION: When installing the serpentine accessory drive belt, belt must be routed correctly. If not, engine may overheat due to water pump rotating in wrong direction. Refer to Belt Routing for correct belt routing. Or, refer to the Belt Routing Label located in the engine compartment. The correct belt with correct length must be used.

    Position fan shroud and fan blade/viscous fan drive assembly to vehicle as a complete unit.
    Be sure the upper and lower portions of the fan shroud are firmly connected. All air must flow through the radiator.
    Install two fan shroud-to-radiator nuts Fan Shroud Mounting Hardware
    Be sure of at least 25 mm (1.0 inches) between tips of fan blades and fan shroud.
    Install fan blade/viscous fan drive assembly to water pump shaft.
    Fill cooling system. Refer to Refilling the Cooling System in this group.
    Connect negative battery cable.
    Start and warm the engine. Check for leaks
