tricks to replacing serpentine belt on 97 jeep wrangler?
Posted by sm0022689 on
I just replaced water pump on my 97 wrangler, 4 cyl- without AC. Engines with AC are a little different. Since I don't have one, I can't saw how to change the belt--- but here it is for the 4 cylinder 1997 without AC.
So I had the belt off, and last thing was to put it back.
A. If you are unsure about memorizing the belt path, make your own drawing. If you are absolutely sure you can memorize the belt path---- make a drawing. Just some circles for each pulley.
Removing belt. Key mechanical location: The tensioning idler pulley. This adjustable tensioning pulley is on the right, below the power steering pump. It can be moved on a diagonal to tension the belt. The key to moving it is you must loosen the idler pulley mounting screw about two turns.
Locate the idler pulley. There is a hex head screw in the center. Use a 15 mm combination wrench to loosen this. Turn counter clockwise two turns.
Now, locate the tension adjusting screw. Look at about 10 oclock position above the idler pulley you just loosened, near the thermostat housing. There is a hex head that runs a long screw diagonally behind the plate. There is a block mounted to this screw that holds the idler. So turning this screw changes the tension.
Using a 15 mm wrench, turn this screw counter-clockwise to loosen the tension on the belt. A socket and ratchet drive will help. You will need a universal or a 3 in' "wobble" extension, because the thermostat housing and temperature sender are in the line of the hex head screw drive.
Good word: This rod is likely to be rusty and VERY stiff. Do not keep turning this if it is getting stiffer and stiffer. That means rust is jamming up the threads. Lubricate the block area on the back of the plate, directly behind the idler pulley, and work the tensioning screw backwards and forwards to get the threads cleaned up. If you have time, (probably an hour extra) you may wish to back the rod right out and remove it for wire brushing, and then re-install with marine grade anti-corrosion grease. I did this five years ago and it still is always moving freely.
Once tension is off, remove the belt.
Thread up the new belt. Expect to have to loosen the idler even MORE, because this new belt is not stretched at all.
Bring tension back up with the tensioner screw. Use your thumb to press on the belt on one of the long spans. Under moderate pressure it should move about 1/4 inch.
Tighten the pulley center screw to about 13 to 15 foot/lbs. If you do not have torque wrench, just make sure you don't use any more force than you can put on the wrench using only your "pinkie" finger. This is usually safe to prevent over-tightening anything on the outside of the engine.
I borrowed this quote from JeffsJeep at the wranglerforum.com.
A look at the FSM for the 97 shows:
BELT TENSION SPECIAL TOOLS BELT I SPECIFICATION
NEW SERPENTINE 800-900 N BELT (180-200 lbs. force) *
USED SERPENTINE 623-712 N BELT (140-160 lbs. force)
So if you have a tension measuring tool, then you can check it. If not, I suggest being conservative with tension. If it slips when wet, you can snug it up then. If you make the belt too tight, it wears out the water pump bearings.

This little problem seemed to come out of the blue. I started the jeep up and the gauges were all dead...speedometer, tach, fuel, oil...everything. The vehicle starts just fine and the lights all come on when the headlights are on. The initial start up indicator lights all come on when I start the vehicle and turn off as per usual. Im thinking its a fuse. So I check the fuse box and find one labeled ''instrument cluster'', sounded pretty good to me...but it is fine. Is there another fuse for just the gauges? I have a 1999 Cherokee.Dash is dead.Put new one in still dead.Don't have a clue

I just replaced my transmission with a junk yard model. Before installing I adjusted the bands acording to the specs in my Haynes Repair Manual. Transmission shifts ok but seams to drag in reverse gear as if the parking brake was on. There is a draging noise and the vehicle seams to working hard to go backward on level ground. I was wondering if they may have listed the wrong specs for the band adjustments. Thanks Carl
Posted by camcroft20... on
Don't have specs on band but the rule is that it should be close enough to the drum to engage without slamming, and loose enough to permit drum to turn without band dragging on it. Biggest problem I've seen people have when adjusting is that adjustment tightens down while turning lock nut. To avoid this, I usually adjust a bit looser than final adjustment so it tightens to correct position instead of becoming too tight. Don't drive 'till you have it right or you will burn band surface. When engaged in reverse, band should be applied and cannot drag. If you adjusted another band, check that one for improper adjustment.

high oil pressure 80 psi on a jeep wrangler, what could be the cause?
Posted by uccelli on
Possible stuck pressure relief in the pump or a defective sending unit. Try putting a container of Marvel oil in there and see if it helps. Also putting a mechanical pressure gauge on it temporarily will give you an idea if the pressure really is that high. if pressure remains that high it can cause the filter to fail and leak. Therefore if you can't find an external cause, then the pump will need to be replaced or you can loose the engine if filter fails.

I have a 97 wrangler 2.5. Check engine light is on, running lean, loss of power and high fuel consumption. I have replaced the o2 sensors, reset check engine code. light stays off and engine runs great for a couple of days and then goes right back to running poorly / check engine light back on. I know its not the o2 sensors...what else could it be?
Posted by willoughby... on
Something odd about what you posted. An engine that is running lean shouldn't be using a lot of fuel. Lean is when there isn't enough fuel going into the engine. Two other sensors that regulate fuel flow are the map sensor and throttle position sensor. Temp sensor generally would cause a rich condition but I'd test that too. Be sure to check for vacuum leaks at the manifold and lines as well as fittings... A vacuum leak will give the O2 sensor a lean reading...seeing that, the computer will try to compensate by adding fuel. Clearing codes can change the way it's running but as soon as the computer runs through it's internal diagnostics it will turn the light back on if there is a problem.
