Where is the PVC valve on a 1991 Nissan 240sx?

I believe it is on the top of the passenger side valve cover.I had a 1991 240SX and I believe that is where it is located.If not then check the drivers side valve cover.It would most likely be silver at the bottom and black plastic at the top with a hose going to it. ..

AnswerI had the same problem. It is very hard to reach. It is under the intake manifold. It only looks like a nut with two hoses connected to it. I have not replaced it since it is hard to reach.

How do you replace the heater core on a 1995 Nissan 240SX?

ALWAYS DISSCONNECT BATTERY TERMINALS (SO AIR BAGS DONT GO OFF)first YOU MUST PULL the entire DASH to get the the heater core housing located behind the stereo...ill see about getting u some diagrams...anywho in the engine compartment at the firewall a little to the passager side where the brakelines coming from the master cycinlder head south (just to the right) are the 2 heater hoses that are attached to the heater core remove these with a a Phillips head screw driver and disconnect hoses. when this is done and the ENTIRE DASH HAS BEEN REMOVED u will see the 3 pecies that consist of ur heating system the one on ur far left is the one ur after it is behind where the stereo was and houses the heater core u only want to remove this because the one to the right houses the evaporting core for ur a/c and it costs about 350-400 to get ur ac recharged (not to mention the gases in side are toxic and more the cold enough to burn u)

after u have removed the heater core install the new one and do everything above in the reverse orderwhen that's done youll need to bleed the cooling system. first add antifrezeze at the rad. until its filled then let the car run intill it gets up to normal temp (196 degrees F) leave the rad. cap off while doing this. after car has reached temp turn off engine refill rad. and reinstall rad cap. then besure the resavoir is full (located beside the passager strut tower)and start engine. when at nomarl oparateing temp...there is a 10mm bleeding screw on the top of the thermostat housing open only until u have fuild/ air coming out and leave open for about 3min or until u have continuous fuild NO AIR and retighten.

well think that's it enjoy and good luck (you'll need a full day to do this)

Will a bad O2 sensor or Tps throttle switch prevent a car from starting?

No it will not. As a matter of fact, the O2 sensor is actually being ignored when you start the car, until it goes into closed loop mode.

O2, no. TPS, possible.

How do you remove and replace a clutch fan on a 93 240sx?

the clutch fan is easy to remove and replace. you will see it on the upper most pully(water pump). just four 10mm nuts to take off. however the pully likes to spin so i use a screwdriver to hold it still or you could tighten the belt so it wont spin, just remember to loosen the belt back to where it is supposed to be once you are done.

How do you change the distributor on a 1996 Nissan 240SX?

buy a new distributor cap and rotor. Unscrew the distributor cap (on the drivers side of the engine block), take note how the existing rotor is sitting, remove it, and place the new rotor in the same position. Put on the distributor cap and screw it into place... very simple job. thats how you change the rotor......he asked about the distributor....try again.

How do you fix high idle problem on a 89 240sx?

If your idle was fine and then just became high, don't adjust the idle control screw. Your problem would be indicative of another issue. Perhaps a vacuum leak. turn the idle control screw to the left ... no neither of those.....your are getting air that is accounted for by the mass air flow sensor....there for its either a) throttle plate not closing or b) idle air controller stuck open.

Where is the PCV valve located on a 1995 240 SX?

Actually it is not under the intake it is on the valve cover, in the forward most passenger side part of the valve cover. To change it you have to remove a 1/2" diameter hose that runs to your air intake and jiggle the valve then pop in the new one and reconnect the hose

How do you change out the rear end on a 1989 Nissan 240SX?

for all 240sx'sThis goes for all years of Nissan 240sx's (1989-1998). This refers to non ABS and non HICAS models, difference may exist in process.

Tools needed: 14mm socket 12mm socket 18mm socket 12mm open end wrench 14mm open end wrench Hopefully someone to help.

Steps:

1.) Pull the ebrake

2.) Make sure transmission is in neutral

3.) Jack up the car and put on 4 jack stands.

4.) Remove drive shaft bolts from the rear end carrier, this should be 4 14mm bolts which you will need to do 2 at a time. Once the first 2 are removed, disengage the ebrake, rotate driveshaft until the other 2 bolts are visible, pull the ebrake again (this is where having someone to help, well, helps).

5.) Disengage the ebrake Unbolt the axles, depending on the year and other factors, your car may have 5 bolt or 6 bolt axles. Unbolt the axles with the 12mm socket and open end wrench.

6.) Slip the axles off of the carrier

7.) CATION: When doing this, it helps to have a second person or a jack stand under the rear end as it is heavy and will more than likely break your face. Unbolt the 2 carrier bolts which are attached to the sub frame with 18mm socket.

With this, the rear end should come out with some finesse. Good luck.

Timing Belts and Chains

Where and what are the timing marks on 89 Nissan 240SX?

Facing the engine, look down at the top, left of the crank pulley. You will see a post sticking out of the block. With the engine running, if you shine a timing light at the post you will see six notches on the pulley itself, right at the edge of the belt. Going from left to right the notches represent 10ATDC, TDC (red), 10BTDC, 20BTDC, 30BTDC, 40BTDC. The Top Dead Center notch is actually painted red, all the others are either rust or grease colored depending on how bad you valve cover gasket is leaking. Keep in mind this is only for the initial timing at idle of 20BTDC. Any rpms beyond idle and the ECU takes over the ignition timing, you have very little control here. The method for setting is to unplug the throttle pos. sensor, set idle to 650 and set to 20 BTDC. When you reconnect the TPS the rpms should increase to 750. Either way 750 is your optimal rpm and all adjustment must be done with the TPS disconnected, only disconnect and reconect the TPS with the ignition off. Never yank it or plug it in while the car is running. P.S. Try to keep all of your fingers here, its a tight spot to see down to those marks. ---Brandon Garretson ------89 240SX

Transmission Fluid

Chevy Cavalier Z24

How do you check fill and drain tranny fluid for 89 240sx with 5spd man?

well in any manual FR (real wheel drive) car i just use snap ring plyers to take out the "C" clamps that hold the shifter in pull the shifter out and fill from there, just make sure you dont get fluid on your carpet(the smell will never go away) Unless you like that kinda thing:)

This answer was not by me but I DO NOT RECOMMEND DOING THIS. I did this with a Skyline in Japan and found that although it seemed full from the shifter, when we went under the car it took nearly 3 more bottles to reach optimum fill. Dont cut corners tranny's are not cheap. Use the nozzle on the bottle and the pumps at the Auto parts store go underneath your vehicle on a steady lift and fill it from the bottom till it squirts out.

Which is wires do you use to hook up new gauges to tie into the switch on the steering wheel?

It depends if the gauges are for replacing your old ones or new ones. They are located under your dash behind your gauge cluster. Your steering wheel should only have cruise control features and of course the ignition wiring. 'i suggest you go to a Nissan 240sx forum, register, and become a member, there should be links to manuals and diagrams there. Use the search engine on them. :D
