Question about 1998 Nissan Altima

1 Answer

My car was in an accident and I'm doing all the repairs myself. so far the alternator, radiator, idle pulley,and front head lights, are what i've got to replace. but i also my fuse box by the battery was blowing fuses and i may have a short. after i install the parts i don't know what wires or connections go or connect to.. i had to take over since my boyfriend didn't really pay any attention when he pulled everything out.. HELP...

I can only say you, really need a factory quality wiring diagram.
The haynes and chilton manuals you hear about will be too genaric.
You need a diagram for all the nissan's for your model year.

This is definitely a do it yourself project.
Clean work and not too difficult,but no professional will touch it.
A body shop might,but you can't afford that.

Only problem is see,is you going to salvage yards chasing parts of a wiring harness,if yours is too bad to replace individual wires.

Also you have to read and understand the wiring diagrams,use a volt meter,at least on continuity or ohms,and may have to crimp on terminals or solder

You always take pictures,bag and tag and use a lot of sharpe markers,and write lots of discription on removal of things.

Put your hands on the carpeting underneath the two front seats. If it feels wet of damp, your heater core (matrix) has failed and will need to be replaced with a new one. You may also want to check your radiator for a blown head gasket... a dye test kit is available from both AutoZone and NAPA; possibly others, that will make the decision easy... just follow the instructions. A blown head gasket is not the end of the world, although it is expensive to repair properly. There are a few sealants out there to repair small leaks... the best sealants aren't cheap, but far less costly than a full-on head job. Before you g that route, place a clean and flattened cardboard .box under the engine and run your vehicle to try to determine if there are any leaks anywhere. Sometimes, older hoses have pinhole leaks than evaporate as soon as they come out when the engine is hot. Check the expansion tank for cracks too, replace its cap as well as any separate radiator cap... they do fail from time to time.

Radiator not holding water and sounds like air is getting in engine when put into gear and give it gas


You either have a hole in the radiator or radiator hoses. How hot and how long was the engine hot? You may have a cracked head gasket.

I was driving and all of sudden the serpentein belt ripped and the car started to shake like crazy. then it started to smoke and overheated. one of the pulleys at the bottom, not sure if the harmonic...


Power steering pulley is on the top. The largest pulley is the crankshaft pulley.
But the 2 on the bottom are the crankshaft pulley and ac compressor. Slightly
above those 2 pulleys is the water pump. Which ones not turning?
And when the serpentine belt broke your water pump was no longer circulating
engine coolant because the belt turns the water pump.

When the serpentine belt breaks you should not drive the car even
though it will run. How long did you drive the car after the belt broke?

So you replaced the belt and then started it? And you can actually drive in reverse?
If you drove the car very far with the belt broken you may have done damage to your engine. I mean
its most likely you did do some damage.

2003 dodge intrepid sxt 3.5 over heated replaced the thermostat and still over heats might be water pump where is it located and what is in volved in fixing this


The water pump is located in the front of the engine & is driven by the timing belt. So if you go in there you might as well replace the belt and tensioners if needed.
Drain the cooling system (turn the radiator drain 1 full turn only)
  1. Remove the upper radiator hose
  2. Remove the top radiator support
  3. Remove the two 10mm head bolts from either side of the radiator and gently pull the top of the radiator forward to gain a little more room
  4. Remove the four 10mm head bolts holding the cooling fan module to the radiator . Remove the four clip nuts and the cooling fan electrical connector and lift the fan module out of the vehicle
  5. Loosen and remove the drive belts and remove the three 13mm head bolts holding the alternator belt tensioner pulley to the timing cover
  6. Remove the three piece timing belt cover (the lowest piece can be accessed through the crankshaft pulley by turning the pulley and removing the bolts)
  7. turn the crankshaft pulley and line up the timing marks on top dead center
  8. Remove the timing belt tensioner two 13mm bolts and remove the tensioner (If the tensioner pulley wheel is made of plastic you will want to purchase a revised steel tensioner pulley) . Put the tensioner in a suitable vise to compress it and install a small allen wrench from the front to hold it in place (close the vise slowly to compress the tensioner)
  9. (If need be) Remove the plastic tensioner pulley (the 15mm head attaching bolt can be removed without removing the crankshaft pulley)
  10. The timing belt can easily be slipped under/around the crankshaft pulley by slightly bending it to the outside of the timing belt housing on the drivers side and working it with your hand through the crankshaft pulley . No excessive force is needed to do this and be sure to clean the area well prior to installing the new belt
  11. With the belt removed , remove and replace the water pump . Coat the gasket with a little RTV silicone and clean the gasket mating surface well
  12. Install the timing belt in the opposite direction as removed . Make sure that all the timing marks are lined up .
  13. Reinstall the timing belt tensioner

    Note: There are several different length bolts used, so pay attention to where they are removed from, they must be installed in the same placement.

    I hope this information was helpful.

Hi,
Unscrew the idle pulley first.
Look for a small pulley where the a/c belt passes through. That is the idle pulley, the screw on the bracket of that idle is on the top side where you could adjust to loosen the tension of the belt. Before loosening it, loosen the bolt on the front of idle pulley.
Hope FixYa helps you out!

Nose that sounds like Idle pulley is gone


You may be right it may be a bad pulley, you will need to remove the belt and spin each pulley by hand and see if one is bad, this is very common on these jeeps, i ve seen the alternator also make that noise.

What part is located in the front of the engine between the engine head and the radiator, it is making a rattling sound at high idle


lots of parts, alternator, water pump, a/c compressor lower area . many of them are on the serpentine belt. the pulleys and tensioner can make rattles. you need to confirm which part has the rattle or vibration, use a stick or screw driver. touch one end on the part and the other near your temple...any noise/vibration coming through?

fiind which one it is. lower noise on the crank can also sound like its coming from up front and that's a deep rattle.

Dodge Dakota charging issues


You put pulleys on to increase power , but slowed down the alternator. Theres your sign. At idle speed the alternator isnt spinning fast enough to charge. So you can put original pulley back on, or a smaller alternator pulley.
