Top 20 1984 Jeep CJ7 Questions & Answers

from thermostat hosing, through carby to heater core. other back to water pump

check the splines for consistency as many have a master spline ( one wider or like 2 as one) so that the steering wheel always ends up in the correct position you may have to fit a different yoke to the box to take the new shaft

Don't believe there is one for headlights. Your jeep is too darn old: I can see wiring diagrams going back to 1986 at a site, so I looked at one for an '86 CJ7. Unfortunately not a complete headlight wiring diagram, however, so you're getting a two bit answer, with inflation worth about 10 cents. lol. The headlight switch gets power from a fusible link (Fuse link A) that looks like it may be located on the starter solenoid terminal- two fuse links- A & B, there somewhere. But this same fusible link A also supplies power to the fuse block with the park/tail lamps, hazards, brake lights, and a couple others. So if you have stop lights and park lights, then the fusible link is good, so you should have power to the headlight switch. Neither the fuse block, nor the instrumentation diagram, shows any fuses for the headlights. A lot of older vehicles did not have headlamp fuses, because the light switch had a built-in circuit breaker. My guess is you have a bad dimmer switch, or the connection there may be bad. Or check if you have power to the headlight socket with the light switch on, and if you do, there may be a headlight ground problem.

there is only one way to do it but you wont have the electronic equipment .the easy way is you have to be two people one for the ignition key the other one whit a insulate pliers you take a spark plug wire and you put the end near the engine if your coil works you will see a bleu spark . But it could be your wire that are getting hold and they leak power or your spark plugs it is better to get a book they will show you all the steps.

sounds like internal transmission issue need to have the dealer look at it

not true, at all , any ASE mech can do this.... sorry, its a fact. the linkage (A/T or M/T , 4wd lever or main gear shift lever>???) try hard to say , exact what part is bad. Clutch A/T box 4WD, issues, ( on my 5th jeep, and have 2 now) Can fix any car. if i was there, id have you, show me what to do , to get the failed symptoms. you;d say, sit here, and grab , this? what is this. the manual stick shift, and id , push in the clutch. and id see , the clutch works but the shifter parts (bushings) are shot and the lever flops about,,,, so i pull it down and rebush it with factory parts. or ,if an A/T id sit there, and put it in Drive, the car dont move i then try all other gears, L 2, R , do they fail too??? i make sure the linkage shifts correct at the actual tranny. if not the linkage is bad (loose) or needs adjustment , (FSM covers ways and spec) like that. no mech needs to know jeeps. not at all, there is nothing magic here. "like French cars" you only need to know 4wd cars. both A./T and M/T do post back with car spec. with options. we dont know. that. cant see it. if your car is not stock, then sure , any mech, will have trouble. frankejeeps or fanken cars of any kind, are a big problem. there is no limits to the frank (hacks) is why, done many, many shops will look and see all the hacks and not even touch it for good reasons (many, ask)

make sure that the fuel line from the tank to the pump is not dry or cracked; the pump could be sucking air.

No, your Alternator is a stand alone system

see the diagram vacuum hoses: God bless you

• Hi I can help,

• To change the headlight on a 1976 - 1986 cj7 headlight you can reference the diagram I put up as well for a visual.
• Basically there is a bracket that has two screws on top and two below that when removed, release the light assembly.
• From there you can access the bulb in the back by twisting it out and removing the connector.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using fixYa.

There are several ways to do it
a. Check carburetor if not clean pump it on the intake if that not solve try to clean it. with Lacquer thinner to dissolve the dirt.
b. Check spark plug if some are not working. In checking try to pull one by one the high tension wire and listen if the sound vary if the sound remain when pulling one wire mean you have problem with your spark plug. So replace all spark plug with the same spec.
c. or lost compression on cylinder.
d Check if you fuel filter if some dirt and replace it.
e. Clean your air filter with compressor or replace it
f. Check the clearance to the Contact Point it must have 1 mm or .8 mm spacing when not at firing mode ( just like the thin of the hacksaw blade the space of the gap of the contact point.)

Do compression check. Probably blown head gasket. Chelly

Their is a few things it could be depending on what kind of loose you are talking about if you mean play in the steering wheel you can adjust that out with a allen wrench on top of the steering box but if your talking about swaying loose that could be either a leaf spring bushing or a swaybar bushing.

sounds like it was not wired properly-try running a wire from the positive side of the battery to the positive side of the coil, see if it runs-if so, you need to look at how the ignition switch was hooked up.

If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing

• The heater housing is usually under the dash and must be removed to gain access to the heater core.
• Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.

The heater housing is disassembled to get to the heater core. Heater Core

• Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
• Remove the heater coolant hoses.
• Remove the cable and/or vacuum control lines (if equipped).
• Remove the heater core securing brackets and/or clamps.
• Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
• To reinstall the heater core, reverse the removal steps.

When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

it is a regular thread but you almost need an impact wrench to remove bacause they put them on tight at the factory

You should soak it with a mild degreaser & scub it with a brush then pressure wash it & let it dry completely where there is no posibility of contaminants getting on it & then mask off the windows & paint away. your lucky. these are the easiest things to paint. just be sure to use a good quality paint & let it cure @ least a week before washing.
