you may want to check your water pump it sounds like it may not be circulating. you may have a blockage somewhere but its un-likely...also make sure the thermostat was installed correctly and it was for the correct temp to open 205 degrees F is good. lastly check to make sure there is no coolant with your oil , or vise verse. good luck hope you find out why.

Low reverse sprag is broken

Yes, put it back together and see if it comes off again. You may have over-charged your AC.

Does the leak show up on the ground when you are parked with the engine running or stopped.
Determine where it's leaking from. Hose? near fire wall, near radiator. Water pump will leak when it's worn.
Can you smell it when you're inside the car? heater core.

Hi there:Check this about PDC...The high-current fuses are coded as follows:Hope this helps.

My 2003 Jeep Grand Cherokee Laredo, It slips when i turn left all the time!!! What is that??

I am going to assume that it will not run even if you push on the accelerator pedal?
Can you install or attach an old timing light to the spark plug wires, turn it one and try to start it. The light should flash with the engine running, but if it shuts off at time of engine die, and the engine is still spinning, you are losing spark, My suggestion is the cranks shaft sensor on bell housing.
Second, install a pressure gage on the test port on the fuel rail and watch it as you start the engine, fuel pressure should not drop as the engine dies, if it does, the pump is not working correctly. There are two modes of power to that pump, one to start and timed, for only a few seconds to prime the system, and one to run continuously. Find the wires going to the pump at the tank. Connect test light to those wires and watch what happens during crank and at stall, You should not have the pump shut off and the engine dies.
If you have spark, and fuel pump working, when did you last change the filter,,but I put that LAST.
It has to be one or the other of these.
Good Luck

Check your grounding strap from the frame to the block if ti is not grounding or it is not in good shape it will not charge the battery

Broken valve spring or hole in piston youd know the piston cause you would hear it pull the valve cover and take a good look make sure all is well. might have oil dripping in from valve if spring is broken or weak and not closing all the way you do not have to pull the head to check this just the valve cover and check the valve seals they may be rotted do the small stuff before pulling the head. use a good flashlight and take a good long look with rags in hand go over all the sufaces around the area in question you may have a crack hope not but do a good check of the area did i say do a good check of the area ok

get used ecu from wrecker and switch out and c if that works
