This could be the bolt becoming loose and then falling off.

The bolt could of sheared off.

That's why when I service vehicles, I check other part's in the area's of the vehicle I am working.

On Polo's, I check the gearbox mounting bolts. I have found a number of the bolts loose.

2004 Kia crank bolt broke off on hiway why


without seeing the damage directly, it would be difficult to say. however, it could have been a faulty harmonic balancer that failed, causing the bolt to shear off or even simple metal fatigue.
either way, it will be an expensive repair

2005 Dodge Caravan, temp gauge has been rising to "hot" while driving. Just recently, van lurched while driving 30mph and then the check engine light came on right after. Temp gauge was normal...


I would guess that the lurch and the engine light on was telling you that the engine over heated and you may have done damage to the motor.. IF you have blown a hose or radiator or lost a lot of water then the temp gauge sender has no coolant to read so it will read as normal. because it is reading an over heated piece of metal that it is screwed into and not the coolant temperature.. Have a compression test done to determine possible engine damage. Have a pressure test done on the coolant system to find the cause of the loss of coolant. Do a flow test done on the radiator to check for blocked cores. Check operation of cooling fan especially if you have a viscous fan hub.

Acura legend ac control untied stop working along with the fans any idea wat could it be


The rotary control switch on the dash controls the blower motor for the A/C. The A/C will not turn on unless the blower motor is functioning properly. The passenger-side radiator fan will not turn on until the A/C begins running. BUT the driver's side radiator fan should always work. Ergo, check the function of the blower motor (located underneath the dash behind the glove box). Usually when it goes bad, it's because of the blower motor RESISTOR (mounted inside the blower motor housing). When the resistor goes bad, the blower motor shorts out, causing it to fail. The switch rarely ever fails. The radiator fan relays are located next to & on both ends of the radiator. Check them too. In the link, the blower motor RESISTOR is #5.

My fan is hitting a pulley? what is it hitting, why, and can I drive safely to the mechanic or parts store?


Most 98 model Jeeps use an electric fan mounted to the radiator. If yours has a fan blade mounted to the water pump pulley, the problem could be the bearing in the water pump or the bearing in the fan clutch.
There-s no way for me to know what it is hitting without being there in person.
You may be able to remove the fan blade and leave the pulley bolted to the pump and drive the truck a mile or two.

Losing a lot of coolant. I don't see a leak. I started to drain the system and it smells burnt to s**t. What might my problem and possible solutions be?


see this causes and fix it. God bless you
Water pump -- A bad shaft seal will allow coolant to dribble out of the vent hole just under the water pump pulley shaft. If the water pump is a two-piece unit with a backing plate, the gasket between the housing and back cover may be leaking. The gasket or o-ring that seals the pump to the engine front cover on cover-mounted water pumps can also leak coolant. Look for stains, discoloration or liquid coolant on the outside of the water pump or engine.
Radiator -- Radiators can develop leaks around upper or loser hose connections as a result of vibration. The seams where the core is mated to the end tanks is another place where leaks frequently develop, especially on aluminum radiators with plastic end tanks. On copper/brass radiators, leaks typically occur where the cooling tubes in the core are connected or soldered to the core headers. The core itself is also vulnerable to stone damage. Internal corrosion caused by old coolant that has never been changed can also eat through the metal in the radiator, causing it to leak.
Most cooling systems today are designed to operate at 8 to 14 psi. If the radiator can't hold pressure, your engine will overheat and lose coolant.
Hoses -- Cracks, pinholes or splits in a radiator hose or heater hose will leak coolant. A hose leak will usually send a stream of hot coolant spraying out of the hose. A corroded hose connection or a loose or damaged hose clamp may also allow coolant to leak from the end of a hose. Sometimes the leak may only occur once the hose gets hot and the pinhole or crack opens up.

My 1997 Dodge Intrepid overheats. I've replaced the thermostat, and it continues to overheat. I noticed adjacent to one of the radiator hoses, a ribbed hose that is split. Could this cause the car to...


Now that you've eliminated the thermostat, it could be a number of other things. Don't drive the car too far until you've fixed the overheating problem - overheating can destroy an engine.

That split ribbed hose you see is plastic wire loom - it carries and protects electrical wires, and is not the cause of overheating.

1. Low coolant level
2. Radiator hose split/cracked, causing low coolant level.
3. Head Gasket - leaking, causing low coolant level
4. Thermostat - stuck closed (you eliminated this possibility)
5. Radiator cap - worn/damaged
6. Radiator fins - obstructed by debris/cardboard
7. Water Pump belt - missing/broken
8. Heater Core - leaking, causing low coolant level
9. Intake Manifold Gasket - leaking, worn, damaged
10. Radiator Fan Relay - faulty
11. Radiator Fan Blade - broken, missing
12. Radiator Fan Sensor/Switch - faulty
13. Water Pump - leaking, causing low coolant level
14. Radiator Fan Motor - faulty

My primary suspects would be Rad Fan Relay (#10), and
Rad Fan Switch (#12).

Overheating


most cooling systems are designed to have a 6 deg difference in temperature from the inlet to the radiator "hot coolant in" to the bottom hose of the system the "engine coolant feed. cooling systems are pressurerized to help the coolant carry the heat away from the hottest parts of the motor.
here are a few things to check check the rubber seal on the bottom of the radiator cap for tears uneven surfaces, ect if damaged replace it. your truck has a coolling fan this is called a clutch fan. these clutches can go bad and cause the air flow through the radiator to be comprimised by the slowing of the fan. you should be able to see if this is happening just by watching the fan to see that it is turning as fast as the motor.
then the 2 most common causes of over heating are a thermistat that is sticking or stuck. these are cheap parts and should be replaced as a matter of routine maintinance. i change mine every year its cheaper than getting a warped head from over heating. this is located on the engine end of the top radiator hose and is located inside the housing that is bolted to the block with 2 bolts.
check the back side of the oil filler cap that is located in your valve cover tanish to white collored sludge here will indicate water in the oil and point to a blown head gasket. also if you have any oil in the radiator.

How do i change a water pump on 1996 grand cherokee limited V8


I'll assume you have a 4.0l

The 4.0L engine is equipped with a reverse rotation (counterclockwise) water pump. The word REVERSE is stamped or imprinted on the cover of the viscous fan drive and on the inner side of t he fan. The letter R is stamped onto the water pump impeller. When replacing water pump, ensure proper pump is installed. Installation of the wrong water pump will cause engine overheating.

NOTE:On models with 4.0 L engine, front grill must be removed to access radiator draincock. Draining cooling system can be accomplished by removing drain plug from side of block as well as by loosening radiator draincock. Drain plug is located on lower left side of engine block.

Disconnect negative battery cable. Drain cooling system. Disconnect electric cooling fan connector. Remove electric cooling fan and electric fan shroud assembly (if equipped).
Loosen, but do not remove, 4 water pump pulley-to-water pump hub bolts and 4 viscous fan-to-idler pulley nuts. Remove accessory drive belt. Remove 4 viscous fan to idler pulley nuts, and remove fan and shroud together.
Remove 4 water pump pulley bolts and remove pulley. Remove power steering pump and bracket. Disconnect heater hoses and lower radiator hose at water pump. Remove 4 water pump retaining bolts. Remove water pump.

Air conditioning problems


it may be caused by overcharge or a plugged orifice tube it could have a ruptured dryer bag in the receiver, you could have too many bus on the condenser or radiator and the fan clutch may not be working causing the temperature to rise and the pressure to increase.
