It is vital that the owners understand the way to maintain the 2005 Jeep Grand Cherokee Limited (5.7L V8 Hemi ) s engine if you want to take care of your 2005 Jeep Grand Cherokee Limited (5.7L V8 Hemi ) property.When compares with the various other sorts of vehicles,the majority of 2005 Jeep Grand Cherokee Limited (5.7L V8 Hemi ) cost is really a small fortune.You know the feeling if your car has been running hot.An overheating engine is usually more than a bummer, If you do not take good care of this good killer,it will leave you on the side of the road ,it will be an expensive repair bill.Let us pray that traffic breaks enough for us to get some air flowing over the radiator to make engine temperature needle go down just a little bit. there are only a few things that commonly cause an engine to overheat regularly.Now let us talk about it.Our automobile is often overheating,but what causes this to happen?
We need rule out a few basic things to properly diagnose the overheating problems.
Step 1:Do you think?there is enough antifreeze in the radiator? Don t just look inside the plastic overflow bottle only, you should remove the radiator cap and then look inside the radiator.We should see the fluid level whether it is at its proper level or not. Most cars and trucks will hold a mixture of coolant and water .You should have the cooling system pressure tested for a leak if you have to add more than a pint of fluid .If we see any obvious fluid loss in the engine compartment or on the ground , we should also have the system tested.
Step 2:If you don not see any coolant leak or low fluid level , then you should determine when the overheating problems occurred.If the engine overheats only at a stop or idle ,Most front wheel drive cars will use an electric cooling fan motor located in front or behind the radiator. The existence of function of the cooling fan is to improve airflow across the radiator at stops and low speeds.The fan is controlled by sensors,it regulates the engine temperature and additional load that might be placed on the engine.The cooling fan is required by the air conditioning compressor to operate at idle when the compressor is on.It is a quick way to check the cooling fan operation to turn on the air conditioner.
Also the cooling fan should come on with the air conditioner compressor. Some automobiles will have two electric fans, one is the air conditioner condenser fan and the other is for the radiator .It will have a belt driven fan blade and fan clutch if your vehicle does not have an electric cooling fan on the radiator . This fan should be pulling a large amount of warm and hot air across the radiator onto the engine to keep it cool.The radiator fan is usually closer to the middle of the radiator. The radiator fan is responsible for cooling of the engine, while the condenser fan is responsible for increasing air conditioning efficiency at idle and low speed.If there is ample airflow across the radiator at idle. The radiator is responsible for the primary heat exchange for the engine, and airflow is crucial at this time.
Step 3:Again, we have ample airflow across the radiator, so we must inspect the proper antifreeze circulation.If there is a restriction in the system , it willproduce the same affect.Water calcification can accumulate in the radiator and then drastically reduce the flow of coolant at a very high speed. Removing the radiator from the vehicle are the only two real cures for a clogged radiator.It be a waste of time and money trying to correct a restricted radiator when you use a can of radiator flush additive. Of course there are more technical issues that could produce an overheating problems, but the check list described above will identify the most common.Anything you can do to help the mechanic to deal with the problem will probably result in less diagnostic charges, and it might help insure a proper diagnosis of the problem at once of your 2005 Jeep Grand Cherokee Limited (5.7L V8 Hemi ).
Step 4:You must inspect an electric motor cooling fan ,it will start with ignition key switch off, it has failed and needs to be replaced if the 2005 Jeep Grand Cherokee Limited (5.7L V8 Hemi ) fan motor does not spin freely . The electrical system operates the fan needs to be tested,If the fan motor “freewheels” that . Start the engine and then turn the air conditioner to the coolest setting, if your automobile does not have an air conditioner skip this step.The car air conditioner will operate the 2005 Jeep Grand Cherokee Limited (5.7L V8 Hemi ) cooling fan should activate within five minutes , the fan motor fuse must be checked first and the fuse condition is good the remainder of the electrical system must be checked.
Step 5:A wiring schematic is needed to further troubleshoot this problem ,which is located in a repair service manual. You may use the wiring schematic to trace the circuit through the fuse and relay components, if everything of 2005 Jeep Grand Cherokee Limited (5.7L V8 Hemi ) tests fine, the fan motor has failed and needs to be replaced. The most common repair is the cooling fan motor failure.
This isn’t only theory. You can take these steps into practice.You can deal with the 2005 Jeep Grand Cherokee Limited (5.7L V8 Hemi ) overheating problems yourself.
