Jeep

I just had my Jeep in for the recall of the Cat, and it was re-programmed.

Now after 5 weeks i got a check engine light. I ran the Fault code and got a 72 which say Catalyst efficiency below required level. The Dealer told me the Cat was fine after the re-program now i have to bring it back to the dealer with this problem. Waiting on an answer.

The distributor is synched to zero degrees with a scan tool.

It is best to fully remove door from jeep. Remove all door pannels. Once you get the pannels off remove cotter pin from actuator rod that is connected to the paddle handle. Then using a long flat head screw driver and a hammer tap 2 small flat steel springs out of place or off of the serrated steel holding brackets. (you will have to align the flat head screw driver on the end that almost makes a complete circle and you might have to use some manual force, also keep the serrated holding brackets as you will need them to install the new handles.) Once you have the flat steel springs out you can then tap the serrated holding brackets out using your flat head screw driver or you can pull them out the opposite direction. Which ever you find to be easier. Once the serrated holding brackets have been removed you can tap lightly on the handle from inside the door with your hammer and the handle will almost fall out (you may have to wiggle it a little). This should work on all jeep paddel handles from 1979 up to 1988 or at least that's as far as I can tell from expierence.

depending on year model and condition stock or modified on the side of the engine follow your fuel lines down from the carb or aftermarket injection system

All it is is a different package

Yes, but chances are that you will have to take the compressor off and install an "a/c compressor by-pass pulley". You will probably have to order it as very few places have them in stock. Check with NAPA auto parts. They are the best. AutoZone, Advance, O'Reilly don't carry this item. Check also online since you have to order it but NAPA usually gets it faster than the post office can deliver. NAPA seems to be next day while online ordering SHIPS in two business days.

replace the rear shock asorbers

"Jeep" is a trademark owned by Chrysler, which they acquired when they purchased American Motors Corporation back in the late 70s or thereabouts. The word "Jeep", referring to the military vehicle used extensively in World War II and afterwards, comes from the acronym "GP", referring to a General Purpose vehicle.

The turn signal switch is on the left side of the steering column.

I wouldn't think so, unless it let all the water leak out. Typically in the summer time you are running the vehicle with the AC on and no water is circulating through the heater core, and your vehicle doesn't overheat.

If your heater blows out hot air then it is good. Try replacing your thermostat. If not a clogged heater core could demonstrate particles floating around your cooling system that may ultimately foul your radiator.

I'm going to add to this answer. Without a doubt a clogged heater core can cause overheating on some engines. GM's 2.5L Tech 4 engines are just one of many that will over heat if a heater core is restricted. The way the cooling system is designed on this engine will not cool properly at hard acceleration or high idle with a clogged heater core. In this engine the heater core is fed by coolant from the lower thermostat housing first going through the intake manifold then to the core and then returned back to the radiator via independent heater hoses. If a clog in any part of this would happen it will cause the coolant to stall at the thermostat housing. Usually you will see normal scan tool temperature readings at high throttle, but the temp gauge will usually climb into the red at the same time and quickly return to normal once throttle has been taken back down to idle. You will also notice signs of high cylinder head temps on it's painted surfaces or hard burnt spark plug wires can also be a sign if problem has gone on too long. Blown head gaskets and cracked heads can also result from this very quickly.

....and your question is?

Not much ,but yes they added bolt tabs on the passenger side for the coil to mount to and the timing chain cover has a bigger tab for one of the pulleys. And if your sticking in a 1988-89 into a new year with a automatic make sure you change the cps ring or your vehicle wont start.

You are going to have to provide a little more information as to what the problems are, if you wish an answer.

Throttle plate sticking?

Vacuum leak?

Please give us more info to be able to help you out...

yes it is a bolt

The 4.0 Engine has not made much of a change to worry about. I installed a 4.0 from a 2001 Grand Cherokee into a 1988 Cherokee that had a 4.0. The only difference was that there is no place for the Knock Sensor. No big deal. I just left it unplugged. The coolant sensor for the computer is now located in the Thermostat housing. A new housing from the Jeep Dealer was only $13.00. The rest bolts right up. I hope this helps you out.

easiest way to check is to cover grill in front of radiator and start engine cover will restrict air flow and make engine heat up.by watching temp gauge you should have a fair idea when fan should switch on.if it doesnt switch on you know relay or swith is not working. you can then check switch with a test light to see if it has poer on both sides. pretty much test relay the same way relay will only test when hot enuff to turn on fan

You must be in a place where there is no buildings. then do approx 3 full complete turns. this is supposed to recalibrate the compass.

The thermostat should be located underneath the top hose coming off of your radiator. Remove the 2 bolts holding it onto the top of the engine and the thermostat will be sitting smiling at you. Pull it out with your two fingers, clean up the old gasket with a razor (don't etch the metal), replace the new gasket that came with the replacement part, and reverse removal order mentioned above.

If using RTV it is 55 in-lbs, if using a permanent gasket it is 44 in-lbs.

I ordered mine on Sunday the part cost $33.00 including S&H from Quadratec.
