2001 JEEP GRAND CHEROKKE LAREDO

regular oil

Base (initial) ignition timing is NOT adjustable. Do not attempt to adjust ignition timing by rotating the distributor. All ignition timing functions are controlled by the Powertrain Control Module.Adjusting the timing on a Jeep Grand Cherokee requires special tools and an understanding of engine mechanics. Changing the timing on a Jeep Grand Cherokee with distributor-less ignition requires professional reprogramming of the powertrain control module. This guide covers Jeep Grand Cherokee models with distributed ignition only. you can go to this site and it will explain it. www.ehow.com/how_4521340_adjust-timing-jeep have a good day !!

you might want to check you cam shaft sensor amd also there is a different sensor under the distutor i had to replace both of these on my 95 jeep grand cherokee laredo

There could be multiple things wrong there is a scan tool that can tell you what the problem is. Autozone does this service for free once they check it there will be a code to explain what is wrong.

ok look at your fuel filter .. see that hose that runs from that to your engine???? and next to that is another hose ???? that doesnt connect to the filter but leads away from your engine ?? that your return line..

All modern cars have this generic info light. You have several options:
1) Free (sort of) most oil change places can check it.
2) Buy your own OBDII scanner, about $100 bucks, works for all '96 and newer cars. Gives peace of mind that YOU know what is wrong even if you can't fix it.
3) Take to mechanic and hope they are honest and don't take you to cleaners.

Generally this light is tied to the emissions systems. Your car won't pass a smog check but it may run just fine. If you are capable check all your fluids especially the oil. Good luck.

This relay is a common problem for Chrysler vehicles. Located in the passenger side bumper area (Jeeps). Test the fan first.

Hope helped (remember rated ths help) Good luck.

If it was overheating at freeway speed then it is a clogged radiator. Another cause of overheating is a timing that is retarded. These can be caused by worn timing components etc, although a possiblity it is highly unlikely on your car.
