    The first thing to removing pump is to loosen the big bolt on the shaft of the fan. This piece has a left hand thread and you may get it loose by putting a big wrench on it and hitting end of wrench with a rubber covered deadblow or steel hammer if that is what you have. If you can't break it loose you will need to make a tool that holds the pulley in place. You will need to remove two bolts, one beside the other that holds pulley on, and bolt tool on to pulley. Once you have fan off, gently set it against the rad, then remove belt, remove pulley, and lastly water pump. There's not a lot of room to work, but it can be done. You will see that the bolts are very small holding the water pump on so make sure you do not over torque when tightening. Installation of rest is reverse of removal,except for the belt, put that on last, you will not have to tigten big fan bolt really tight either since the fan turns opposite and keeps it tight when motor running. If you can't get the fan off then it would be better to take to a mechanic. Make sure you double check the pump before taking it off to make sure that is what moving. Let me know how this works for you.

    The first thing to removing pump is to loosen the big bolt on the shaft of the fan. This piece has a left hand thread and you may get it loose by putting a big wrench on it and hitting end of wrench with a rubber covered deadblow or steel hammer if that is what you have. If you can't break it loose you will need to make a tool that holds the pulley in place. You will need to remove two bolts, one beside the other that holds pulley on, and bolt tool on to pulley. Once you have fan off, gently set it against the rad, then remove belt, remove pulley, and lastly water pump. There's not a lot of room to work, but it can be done. You will see that the bolts are very small holding the water pump on so make sure you do not over torque when tightening. Installation of rest is reverse of removal,except for the belt, put that on last, you will not have to tigten big fan bolt really tight either since the fan turns opposite and keeps it tight when motor running. If you can't get the fan off then it would be better to take to a mechanic. Make sure you double check the pump before taking it off to make sure that is what moving. Let me know how this works for you.

Death wobble in 4x4 van


Check you steering and duspension system. Check ball joints and steering linkages. With the vehicle in the floor have someone move the steering wheel side to side. Not whole turns just side to side movement while you look at the steering linkage to identify any loose parts. Then raise the vehicle and check your ball joints by grabbing top and bottom of the tires and shaking them.

Right front side wobbling real bad. someone said something about some kind of "arms" connected to the tires. what are they called?


Lower control arms. There are two bushings that are at the frame, if these are gone then it is possible for it to wobble. I would also check the wheel bearing and ball joint. To check these lift the tire off the ground. For the bearing grab the tire top and bottom push it in and out, if there is any movement the bearing is worn. If these are worn enough they to will cause a wobble. For the lower ball joint have someone put a 2 X 4 under the tire and lift as you watch the ball joint. if it moves up and down in the socket it is bad. All these together can cause a significant wobble. The lower control arm mounts to the frame and the lower ball joint is mounted to the lower control arm at the tire and the bearing is the part that holds the tire on.

Driver side wheel shakes often. I changed brakes and rotors and problem continues. What is the problem.


I would call this 1 of 3 possible problems.....

This first could be a bad or unbalanced tire. Sometimes the multiply ties we use on cars separate between layers, this causes an un-natural bulge that can not always be seen, but certainly can be felt while driving. This is called ply separation. An unbalanced tire, which could be caused by a wheel weight falling off, or a shift in weight that could be cause by something like an impact break or the ply separation, would also cause a wobble that varies at different speeds. The best way to check it out without a shop visit, is to take the wheel off and just inspect it, make sure everything is smooth and even.

Secondly, a wheel bearing could cause a wobble as well. The self test for this is to jack the car up, leave the tire on and wiggle it. It should feel tight all the way around and not move up to down, or side to side. A way to test this unit while driving, which is not always accurate 100% but will give you a clue as to where to look first is drive in an area free from other traffic, when it starts to wobble, turn to both the left and right without touching the break. If the wobble goes away it is likely the cause.

Thirdly the ball joint could also cause a slight wobble. To check this, I usually jack the car up, do the same wobble test as described above, then remove the tire and inspect the joint. A good joint will have absolutely no tears in the boots. It should also feel solid at you try to move the other components that surround them.

Good Luck, we are here if you need anything further.

Zigzag light on megane scenic dashboard comes on car revs high then low usually stalls then coming to a stop. 1998 renault megane scenic rt manual. thanks


this exact problem on a megane coupe is caused by a small air pipe that connects to a 2 inch wide black box that is located under the bonnet near the windscreen on the passangers side. the zigzag light indicates an electrical fault (in this case lack of compression and will affect your revs) if you find this pipe and it has snapped off. the reason for this may be that your engien is lose and moves. grab the engien with 2 hands and see if you can wobble it with allot of play. if so your engien mountings need replaceing. you may also experiance juddering in low gears

Noise in Reverse


Transfer case would only be if you are in 4 wheel drive. this sounds like a rear end or u joint issues. Get under the truck and grab the drive line, if you are able to turn it more then a 1/4 inch each way bad u joints. If not then check the rear end.

I have a wobbly wheel, how do i fix it?


You need to check the hub bearing and the lower ball joint on the vehicle and make sure they are good. If you can jack the vehicle up and can grab the top and bottom of the wheel and wobble it back and forth then the bearing is possibly bad. If you can grab the front and rear of the tire and move it back and forth it could be the tierod end you can have someone watch the parts while you move the tire.

Wobble front end


jack one tire up at a time, from the control arm, so the tire is not dangling ro the spring does not extend, then grab the tire with one hand on top and one on the bottom, and wiggle it, if it moves you have a bad ball joint, then grab it with one hand on each side and move it back and forth if it moves you have a bad tie rod end.
