DenLorsTools.com Summary: Automotive repair blog and video comparing two Miller specialty tools. We have had a lot of questions regarding the Miller 8387 Valve Spring Compressor and the 8516A Rocker Arm Remover/Installation Tools. Both look similar and are for use on Dodge and Jeep 3.7 and 4.7 liter engines. These motors are commonly used in Jeep Liberty, Dodge Durango, Dodge Dakota, Jeep Grand Cherokee etc. *Note – The 8516 has been updated and the newest number has an “A” on the end now making it 8516A. Each tool is for a different job. The valve spring tool allows access at the valve keeper so a magnet can be used to remove it. The 8516A does not have the opening to allow access to the valve keeper.

© DenLorsTools.com Summary: Recent comments from a do it yourself-er that has used a previous article on Jeep Grand Cherokee dash removal. Jim was nice enough to let us know how he has used our information not just once, but on two occasions for different problems. The ability to tackle dash removal has saved him a ton of money. I think we saved Jim a lot of time – now he’s returned the favor by basically writing this blog! Thanks Jim.

© DenLorsTools.com Summary: Jeep Grand Cherokee’s with dual zone have a common problem of blend doors breaking at the point of actuator engagement. Vehicles affected are 1999, 2000, 2001, 2002, 2003 and 2004 Jeep Grand Cherokees. The automatic temperature control can be affected on the driver or passenger side, making the temp control inoperable. Until recently the refrigerant had to be discharged and the dash removed for repair. Now with a WJ blend door repair kit # K6855685AB, from Mopar/Chrysler/Fiat the repair can be done in the vehicle by even modestly experienced individuals. The kit includes an aluminum door door, a plastic door, a spindle, grease and patch material for resealing the evaporator case after repair. PDF Jeep instructions provided in this car repair article.
NOTE – Since this article was written Jeep has discontinued this repair. We used to sell an alternative however, we have discontinued that item also. See HeaterTreater.net for a possible solution.

Common transmission leak on many Chrysler products is the electrical plug housing.
©DenLorsTools.com Summary: A common (Chrysler product) transmission fluid leak which affects many models including Jeep Grand Cherokees is covered here. The leak can easily be mis-diagnosed as a leaky pan gasket. A lot of unsuspecting consumers may end up spending a thousand dollars or more to rebuild a transmission with a leak like this. There’s no recall at this time from Chrysler, perhaps there should be, with such a widespread problem. The good news is that this auto repair blog describes the source of the problem and how to repair. A simple repair process to stop the leak for the cost of around ten dollars. Even a do-it yourself-er and can save possibly thousands of dollars from having a mis-diagnosed leak repaired by a transmission rebuild. The vehicle that the transmission leak occurred in, in this case was a 2007 Jeep Grand Cherokee Laredo 3.7L, GAS, Vin K, Eng Cfg V6.

Summary: Mopar 4.7 engines used in many Jeep and Dodge vehicles share a common problem. Misfires which are accompanied with coolant loss, rear heater not working properly and engine temperatures running a higher than normal range, could have a leaking head gasket. There’s a couple of simple ways to check for a blown head gasket, one is by using a block test kit, another way is to use a cooling system pressure tester and removing the spark plug in the misfiring cylinder.

Summary: This auto repair article covers the common problem of “the key being stuck in the ignition.” The shift interlock system is usually the cause of the key being stuck in the ignition lock. We do a general overview of this problem as it is related to a wide range of vehicles and have a specific vehicle, a 2006 Jeep Liberty that has the problem too. As with all vehicle systems, it’s best to have an understanding of how the system works to be able to diagnose the problem properly. Read the rest…

2003 Jeep Grand Cherokee 4.0 Liter Engine with a P1281 Code.
This automotive repair article is on a specific check engine light code for a Jeep Grand Cherokee. When scanned with an automotive scan tool, a P1281 fault code was retrieved. The code has to do with the engine not reaching operating temperature within a certain length of time after the vehicle has been started. For the catalytic converter to operate at it’s best the engine needs to reach it’s normal operating temp. The cooling system’s thermostat normally stays closed when the engine is cold, allowing the motor to warm up quickly. That’s why the trick of removing the thermostat to let the car run cooler, like back in the 1970’s (prior to on-board computers) doesn’t work well anymore.
