How replace and put back on idler pulley n
Hi there,
Use socket wrench to turn serpentine belt counterclockwise at tensioner to get some slack.
Pull serpentine belt off topside of idler pulley and put it underneath idler pulley, and actually try to tuck it up inbetween engine block and idler pulley. Then close your engine hood.
Then crank engine a few seconds and the belt should flip that idler pulley right off.
Dont even need to start the engine. You can tell when the job is done by hearing a big thud, and seeing the dent pushing out on your engine hood. Turn your key off immediately after hearing the thud, or if the engine starts. You just want to crank it a second or two. Easier than using a puller.
If the idler pulley is really shot to bits, it may come off in pieces; if not, there should be one center bolt and a largish washer. Don't lose the washer or bolt since your new part does not come with those (mine didn't!). Replace everything in the same order. Make sure you follow the torque specifications for the bolt when replacing it.
For the dent on your hood, just whack it back down with a hammer, then spray it with white Rust-Oleum spray paint, or the color that matches your car color.
Hope these help.
Steering pump needs fluid once a week. Doesn't
your power steering pump is going bad the bearings inside are worn out and thats what causes the whining sounds that change when you turn the steering wheel your going to have to replace it.
The left rear wheel wobbles. In checked all the
When checking to see if anything was loose did you also jack the wheel up and check? If not I would recommend jacking it up off of the ground, then just like checking the front end you grab the tire by the top and bottom and try to push it in and out. If there is any movement this is not good, have someone (friend, family) come look to see what is moving. Also grab the tire on both sides and try to push it side to side, again any movement is a bad thing. Also aside from movement you will be able to feel is something is wrong through the rubber. See if you feel any clicks or bumping, if they're there you will know what I mean.
If you don't find anything by jacking the tire up to check try spinning it and see if the rim is bent. If you have no luck with any of these I would take it to a shop. They can spin it on a tire balancing machine to check for a bent rim and also while it is up on a hoist they can check to see if there are any worn or broken components.
Good Luck, please ask if you have any more questions

Parasitic draw on battery
how to check on car with
You will be able to help diagnose the problem by pulling fuses. Take a volt meter and put it to oms. Disconnect the positive battery cable. Put one end on the positive battery termanal and the other on the cable. Note the oms. Now, pull one fuze at a time until the oms drop considerably lower than before you pulled the fuzes. Thats the system that is drawing the power. Once you know the system you can track it down further. It could also be your altrenator. Disconnect it too and measure the oms before and after. take your time and do one system at a time noting the oms before and the oms after. My quickest guess it it is either your altrenator or your radio. Please note, you will have some "draw" no matter what because your clock radio or door lights will draw power. If you want to see this, test the oms with the doors closed and then test with the door open. The oms number will be higher with the door open.
If you don't have a volt meter, you can always test one fuze at a time over night. That would take considerably longer tho.
Drivers seat drop all the
pull the seat out of the car by unscrewing the bolts which hold it down. unplug the wiring first.
when you have the seat out and upside down you will see what is broken and you can fix it or buy a replacement seat at a junkyard.
Slow going up hells and
Two things it could need a tune-up or check the transmission fluid level. Sometimes when a vechicle goes up a hill slow, it could be a sign of low levels of transmission fluid.
A/c where not working added
either a pressure sensor problem or its overfilled or not enough gas ,really this should be done with the right machine to empty system then vacumn and re gas to the correct of gas ,which without going outside in the cold to get the chart thats with my machine i dont know but i would hazard a guess and say it should hold 750grms of gas .just looked in my alldata book and it says 650/700 grms so i wasnt far out but thats for a LS420 the 400 isnt listed in my europeon book
Antenna does not come up
If the antenna motor makes noise, then the antenna motor is ok, and the antenna is stuck, oil it with a light lubricating oil (3-in-1, Marvel Mystery oil, store brands, etc.)
If antenna motor makes no sound, replace. Antenna motor.
I don't have a service guide for this car to help you replace the antenna motor. Usually replacing these motors are a screwdriver job, but you may need to buy a special "antenna wrench" to remove a specialized keyed nut holding the antenna to the body.
Hi.my son (college student/part time
Hi, causes of excessive current drain from a car battery include things like lights that remain on (trunk and hood lights, interior lights, brake lights, etc.) and also relays that may be stuck on, or modules that are not going to sleep or powering down. A fuel pump relay that sticks on may keep the fuel pump running after the engine is shut off. A switch or relay that powers a rear window defogger can stick on, pulling current from the battery after the ignition is off. An electronic suspension module, ABS module or keyless entry module may remain active long after it should have powered down.An accessory such as a DVD player, game console or cell phone charger left plugged into a rear seat power receptacle may be pulling power from the battery. So before you spend a lot of time trying to figure out where the amps are disappearing, check all of the vehicle's power receptacles to see if something is plugged in that may be using power.
FINDING THE CAUSE OF THE CURRENT DRAIN
If the key-off current reading is above specifications (typically, more than 50 mA one hour after the vehicle has been shut off), the current drain is too high. It's time to start pulling fuses and relays to find the fault. Refer to your vehicle owner's manual or a wiring diagram to identify the fuses and relays. Then pull the fuses and relays one at a time until the current reading drops. Avoid pulling the fuses for the PCM or other KAM-sensitive modules until you have checked all of the other circuits.
Once you've found the circuit that is causing the excessive current drain, check the relay, switch, module or other components in the circuit and replace as needed.
Sometimes a bad alternator diode can cause a car battery to run down. A good diode should only pass current in one direction. If it leaks current in the opposite direction, it may keep the charging circuit on when the engine is not running, causing the battery to run down.
