    any older mechanics know how to get this distributor off? The A/C filter/accumulator is wrapped around the top of the engine and the trans sump pan is in the way underneath. I can't imagine how to approach this at home in my garage.

This is a very involved repair. The distributor is located on the front of the motor between the waterpump and the harmonic balancer. the Waterpump ,and anything else in the way will have to be removed. An experienced mechanic with the proper tools and a lift will require at least 4 hours to complete.

Installing a distributor in a 1998 dodge ram 1500 5.9 LT


Replacing Distributors: 1998 to 2005 models
  • Trace the spark plug wires to the distributor; it will be at the back of the engine block, in a cramped space.

  • Disconnect the negative battery cable to the distributor and unhook the air cleaner tube. Unscrew or unhook the clamps holding the distributor cap in place, and unscrew the Camshaft Position (CMP) sensor connector with a screwdriver.

  • Matchmark the distributor housing and the rotor for later realignment, as well as the distributor housing and the intake manifold. Unbolt the holding clamp and remove the distributor.

  • Set the engine at Top Dead Center (TDC) mark of the No. 1 cylinder compression stroke with a socket with breaker bar (long-handled ratchet).

  • Install the Ram distributor, replace the clamp and lightly tighten the bolt. The distributor part number is A1303801 from Parts Train, but numbers differ from different manufacturers. Order using the model, year and engine size.

  • Turn the distributor in its seating so the rotor lines up with the No. 1 cylinder mark on the Camshaft Position (CMP) sensor. Bolt the clamp bolt to 200 foot pounds (22.5 Nm).

  • Reattach the CMP sensor connector and use the screws or clamps to replace the distributor cap. Connect the air cleaner tube and the negative battery cable

Where is the serial number found on a 1999 cabrio distributor?


There was only one distributor number used by VW for all 1999 Cabrios (US market), all references below are for US models only. (for Canadian market there were some different ones). The VW part number is 037 905 205 T, these were made by Bosch. Bosch did possibly supply a some different numbers to VW (Bosch number 0 235 520 066 replaced by 0 235 520 065) but both had the same VW part number and used the same repair parts. There is no serial number for the distributors, just part numbers. The original distributor will have the VW number as well as one of the Bosch part numbers stamped into the body of the distributor. The distributors rarely had to be replaced, as most parts to repair them are available. The ignition hall unit (sensor) is replaceable in the 037 905 205 T distributor. I am a independent parts distributor for VW and Audi vehicles and also a Bosch warehouse distributor. I have the hall unit in stock for this distributor, mail order price is $121.70 + shipping (and + sales tax if shipped within Alabama). I can also install the hall unit in your distributor (if needed) if you send me your original distributor. To replace the hall unit the distributor has to be disassembled and if done improperly the distributor can be made unusable. Call me or Email me if you need more information. 1888VWPARTS vwparts@bellsouth.net

Want to remove and replace the distributor in my 1997 gmc


1 Remove the plastic cover from the engine block with a wrench, then let the spark plug wires lead you to the distributor. It's at the back of the engine block.


2 Remove the negative cable from the battery at the side of the engine compartment; carefully pull the spark plug wires off the distributor cap so you don't damage them. Use a screwdriver to take off the coil leads from the distributor and the electrical connector at the bottom of the distributor.


3 Loosen the clamps and take off the distributor cap. Mark the parts to align the rotor position to the distributor housing and the housing to the engine block. This will help replace parts correctly during distributor installation.


4 Unbolt the distributor hold-down bolt with a wrench and remove the distributor from the engine.


5 Install the new Sierra distributor, aligning the marks for proper seating in the engine block. When ordering the distributor, give the parts dealer your model, year and engine size. You can order part number A1841639 from Parts Train for a 4.3L engine.


6 Re-install the distributor hold-down bolt. Replace the distributor cap and put the clamps back on. Attach the electrical connector at the base of the distributor, put on the spark plug wires and coil leads, and hook up the negative battery cable.

How to remove the pick-up coil from the distributor. 1989 GMC 1500 4X4


The distributor does have to be removed and dis-assembled in order to replace the ignition pick-up coil/stator, and if the pick-up coil/stator is faulty then the distributor should be replaced because the distributor will come with a new pick-up coil/stator and the old distributor will have to be removed anyway and in the long run it will actually save money from not having to pay a mechanic to remove and dis-assemble the distributor to replace the pick-up coil/stator, however most of the time it is the ignition module inside of the distributor that is faulty.




When the engine is at TDC (Top Dead Center) is the ignition rotor pointing to the #1 position on the distributor housing as described below?



The engine should be set on TDC (Top Dead Center) with the distributor cap removed, and there is a mark or notch on the distributor housing that the rotor should be pointing to when the engine is on top dead center. (Look under the distributor cap and find where the number one terminal runs under the distributor cap, and where that position on the distributor cap corresponds with the distributor housing, and it should match up to a mark or a notch on the distributor housing)

This static timing is all that matters and the computer will be able to control the timing as long as the ignition rotor is in that position when the engine is at top dead center.



If the engine is at TDC and the ignition rotor does not point to the #1 mark on the distributor housing, then loosen the hold down bolt to the distributor and turn the distributor until the rotor is pointing to the #1 mark on the distributor and then tighten the distributor hold down bolt.

How to fix a front leaky oil seal in a 1995 Toyota Camry LE


Three seals to check. easiest is the valve cover seal. Number and remove the 4 wires going into your spark plugs. remove 4 nuts holding the cover and replace seal.
Next easiest is the distributor O-ring. Remove air filter assembly remove the distributor cap, then the distributor. With the valve cover still off, loosen the 2 bolts that clamp the distributor down. Remove the 2 terminal leads going into the distributor (4 wire terminal/2 wire terminal) Mark the case of the distributor and the case of the head with one line so you can line it back up on reinstallation. remove the 3 bolts holding the distributor down. Replace O-ring. replace distributor, align, tighten the 2 bolts, then tighten the 3 bolts. replace terminal wiring and cap. replace air filter assembly. Replace valve cover with new gasket. Place spark plug wires back into their proper places. The last one is the oil pan gasket. Drain all oil and remove all blots holding the pan. drop the pan and replace the gasket. Put it all back into place. Do not over tighten the pan bolts as this will cause the gasket to deform, making it leak again.

What are all of the parts needed for a tuneup for my 95 quests


Spark plugs, spark plug wires, distributor cap, and distributor rotor. If you replace all of these you would be doing what is called a major tune-up.

A regular tune-up would be just replacing the spark plugs.

You can check the integrity of the plug wires and distributor cap by spraying them with water while the engine is running. If the engine runs ruff, stall, or you see spark arcing from either the wires or the distributor cap than they will need to be replaced.

The distributor rotor always gets replaced when you replace the distributor cap.

You can also spray the coil with soapy water to see if it is leaking as well.

My 2003 gmc v6 just had its plugs and wires and distributor cap and button changed and i put the distributor button on wrong, it ran fine 4 a mon. or 2 and one of the screws came out of the button and...


The distributor cap and/or the ignition rotor most likely have a crack somewhere and the distributor cap should be replaced along with the ignition rotor. The ignition module could have been damaged as well as the ignition pick-up coil/stator and if replacing the distributor cap and ignition rotor does not solve the problem then the ignition module or the pick-up coil/stator assembly inside of the distributor is also most likely damaged and the distributor will need to be replaced. There is a certain procedure for removing and replacing the distributor, and the ignition timing is not adjustable and it is not set using a timing light or with the engine running, and if you do have to replace the distributor Let me know if you require the procedure to properly remove and replace the distributor or if you require any further assistance.

MECHANIC STATING DISTRIBUTOR PLATE STRIPPED BUT STATING THAT ENTIRE DISTRIBUTOR NEEDS TO BE REPLACED AND ROTOR IN PIECES AND CANNOT BE BOLTED DOWN TO THE PLATE. HOW WILL I KNOW THIS IS CORRECT


The OEM distributor is plastic and the screws will strip if they over tighten the screws, they should not strip on there way out so if there is any stripping. It's caused by shops negligence, screws don't strip on there way out or on there own. You can use an over size screw to secure the distributor cap down and problem solved. If you are gong to replace the distributor, replace it with the upgraded distributor with the aluminum distributor. Here is a link for that product.

How to replace the o ring distributor


Remove the spark plug wires from the distributor. Loosen and remove the distributor mounting bolt(s). Pull the distributor out from the head. The o-ring is on the distributor shaft. The old one probably needs to be cut off. The new one will stretch and slide into place over the shaft. Put some engine oil on the o-ring, and re-insert the distributor. You will need to turn the shaft to the right position to get it to fit back in place.

If you suspect that your distributor is leaking oil because of a bad o-ring, a new o-ring may fix the problem. However, make sure that the distributor shaft bearing seal is not leaking. You can check this by removing the distributor cap and looking for oil inside the distributor. If the bearing seal is leaking, replacing the o-ring will not solve the problem. You will need to rebuild or replace the distributor.
