    I have a 2001 Dodge Dakota Quad Cab the VIN number pulls up a 4.7 engine but the sticker under the hood says a 5.2 how do i know which engine i have?
  • bpeeblesbpeebles Posts: 4,085
    The 2 engines are VERY different.

    Here is a write-up on the 4.7L semi-hemi. (with photos)

    Perhaps this will help you identify your engine.

    HINT: The 4.7L does not have any sparkplug wires while the 5.2 does.
  • i have a 95 dakota with a 3.9 v6. it has a spun rod bearing. i found a 3.9 at a wrecking yard out of a 98 dakota. will the 98 go in my truck and everything hook up, or is there things i have to change to make it work. or will it not work at all? please help asap before i go buy the 98 motor. thanks, scott

    I'm pretty sure that after 2000 the 318 (5.2) was no longer available.

    Regards,

    You should have no problems swapping in '98 to replace a '95, they're both Magnum versions. A '92 might be better. They used a larger exhaust manifold and were rated slightly higher in horsepower.

    Dusty is correct. The 5.2L (318ci) was replaced with the 4.7L semi-hemi in the 2000 model year. I do not think it is possible for your 2001 to have a 5.2L from the factory.

    Trivia: The 4.7L was first available in the Jeep Grand Cherokee in 1999. Starting in 2000, it was also available in the Dodge Dakota. (Replacing the 1960s-era 318ci)

    Clean the IAC (Idle Air Controller)

    I just bought a 96 6 cyl with 170k miles. The engine is not using any oil anf all cylinders are burning clean. There is, however, some constant lifter noise. The alarming issue is that the oil pressure warning light comes on at idle (600 rpm)
    shortly followed by the gauge. Both go out at 1100 rpm. Suggestions?
  • ronslakie1ronslakie1 Posts: 57
    Sounds as though a good possibility would be some oil sludge build up. The oil light stared flickering occasionally in my wife's Mercury Grand Marquis recently (112K miles) and I ran some motor flush through it for five minutes before the last oil change. That was 3K miles ago and I have not seen the oil light come on again. It is probably worth a try on yours, especially with that kind of mileage on it.
  • bpeeblesbpeebles Posts: 4,085
    I agree with the last appender. Try what he suggests (motor flush) to help clean out the gunk from inside the engine and lifters.

    Also, you may try a can of STP oil treatment when you put the fresh oil in it. This will add extra detergents to the oil to help clean up the lifters. The STP oil treatment also improves viscosity (thickens the oil) which will help quiet the lifter-rattle.

    You should EXPECT the oil to get dirty pretty quickly with the STP in it. You may as well use inexpensive oil because you will be draining it before 3,000 miles.

    If you are REALLY serious about cleaning the inside of your engine. Consider running MOBIL1 synthetic after that. The synthetic oils are extremely good at scrubbing the inside of an engine sqeeky-clean.

    I once bought a car that had 1/4 inch of gunk on the inside of the valve-cover.... I started to run only MOBIL1 in that engine. About a year later, I removed the valve-cover to adjust the valves and I could SEE MY REFLECTION in the shiny metal on the underside.

    My original equipment battery finally died. I had a heck of a time removing the clamps which were like none I've worked with before. They were dug into the posts very deeply and I had to mess them up getting them off. My question: is there a special tool to remove and replace those? Can I just get a normal clamp and somehow clamp the old cables to the new clamps. Or do I have to get it to the dealer for their expertise? Thanks.

    I have a 94 dakota 5 spd
    I filled fuel tank to filler neck and was driving 40 mph about 8 miles from shell sta when motor lost power I floored it got no response it sputtered and died.I could get it to start and idle and it would die after 30-45 seconds.I waited 10 minutes it started I put it into 1st it drove 15 yards and it died again.I went home to get vehicle to tow dakota home I returned 2 hours later I started it and it ran normal so I pulled out onto road drove it to stop sign about 100 yards and died again . I towed it home next day it would start and idle for about 1 minute then quit .It started for me 5x now it won't start,I'm quessing it might be a fuel problem I figured bad gas maybe fuel filter,I went to parts store and they told me this dakota has a internal filter and I need to replace fuel pump cost $160.00
    It seems to be a fuel problem but I'm not sure are there some other things that would cause this? what should I be checking. I also checked for codes and I got 23 and 5

    92 dodge dakota no spark and no fuel pressure

    I have replaced the crank sensor, computor, dist modual, pickup coil. ran 12volts to the fuel pump so I know it works, also have check all the fueses and most of the grounds, and all of the relays I think any one with any thoughts on what else I should check ???

    I am so out of Ideals.
  • I recently acquired a 1999 dodge Dakota from my sister that is rough on vehicles. She said it ran hot, so she replaced the radiator. When I went to pick it up it starts fine but there is a knocking noise in the engine. I checked and there is water in the oil. How do I check to see if she messed up a head or a gasket? Also since the oil is floating on top of the water could this be why it knocks? If I change the oil do you think the knocking will go away? I plan to fix it up for my step son, and don't have a lot of money. Any answers would be greatly appreciated.
  • dustykdustyk Posts: 2,926
    Water in the oil may not necessarily mean its coolant. If this vehicle has been owned by someone that is "rough" on vehicles, it is possible that this engine has not received very good maintenace. In frequent oil changes in combination with short trip driving can build up moisture. This usually shows up as a whitish or light brown frothy element in the oil visible on the oil cap or dipstick. If this engine has a lot of miles and the engine ventilation system is not working correctly, moisture can build up very quickly.

    The detection of coolant in the oil or a bad head gasjket can be diagnosed. I would recommend you perform these tests or have your local repair establishment perform them for you first. Mopars aren't noted for having head gasket problems and I haven't seen or even heard of one in years. A bad intake manifold gasket can cause a problem, however.

    In the meantime I would change out the oil and see if the knock goes away. If it does it indicates that there was probably too much moisture (water) in the oil. Then perform the test for coolant and proceed accordingly.

    Good luck,
    Dusty

    I know for a fact that In 1999, the ONLY vehicle available with the 4.7L was the Jeep Grand Cherokee. The 4.7L engine was first available in the Dakota in the ModelYear 2000 .... but you suggest you have a 1999 Dakota with the 4.7L Somthing does not jiive here.

    HINT: Check if your Dakota has rack-n-pinion steering (1st available in MY2000)

    To more specifically answer your question "How do I check to see if she messed up a head or a gasket?"
    The common way is to do a "bleeddown test" and a "compression test".
  • how do i remove the fuel line from the line that feeds the injectors 2000 dodge dakota 4x4 v6
  • bpeeblesbpeebles Posts: 4,085
    I beleive there is a "special tool" which is intended for this task. Some autoparts stores (Autozone?) will "loan out" special tools.
  • The production date is 8/99 and under the hood tag is 4.7. It must be a later production date
  • I didn't have a chance to change the oil yet but i got a clearer story, The truck was running hot so her mechanic put a new radiator in it. Right after she got it back someone hit her in the front and damaged the radiator so they put in another new one. After he installed the second one he noticed a slight knock in the engine and it hasn't been driven since. I opened the radiator cap and it still has water in it. If it was using this much water i would think it would be empty. I also pulled the dipstick out again after sitting for over a week and there is no separation of water and oil, it all looks the same. When i change the oil i will let you know what happens. Thanks for you help
  • bpeeblesbpeebles Posts: 4,085
    Given the info you show above about your underhood sticker... I beleive you have one of the early MY (Model Year) 2000 Dakota. (I orderd my 2000 from the factory and took delivery in October 1999)

    I assume you DID verify that you have rack-n-pinion steering.

    Now that we have that setteled.... how did you determine that you have water in the oil?

    Just incase you were not aware...
    The very early 4.7L engines had a tendancy to build up water-oil emulsion in the oil-filler tube. There were several 'recalls' pertainig to this. (I am very aware of them because I initiated at least one of the recalls)

    The 2 changes were
    1) The oil-filler cap was redesigned to contain an insulating barrier from colder under-hood air.
    2) An insert (factroy calls it a "baffle") was developed which slides into the oil-filler tube.

    Both of the above changes to the very early MY 2000 4.7L oil-filler tube were intended to reduce the buildup of condensation inside the oil-filler tube.
  • is the dakota 97 magnum v6 motor same used on the ram model? :confuse:
  • bpeeblesbpeebles Posts: 4,085
    Depends on ModelYear of the Ram.
  • Hello,
    I have a '98 Dodge Dakota, V-6 , 3.9 4x4. Its been a good truck over the years and I have taken care of it the best way I can. Its got me around 188,000 miles, I cannot complain much. Low cylinder compression in cylinders 4 and 6 . OKAY needs a new head gasket.
    Tore it all apart and swapped out the gaskets with the top end overhaul kit.
    New cylinder heads- cause they were cracked.
    OK.. RE-INSTALLING the heads went fine - torqued down to spec.
    Now I am installing the INTAKE MANIFOLD onto the heads and I keep snapping bolts--#1 and #2 in the sequential order. I replaced the bolts and bought a new torque wrench- Craftsman dial- in torque release---How could one go wrong? Snapped another with Dodge dealer bought bolts and new torque wrench---
    Haynes book says to tighten to 12lbs and rock around up to 144 lbs---Dodge dealer said to start at 24lbs to 48 to 82 lbs---I have tried Haynes first and broken bolts ---redid everything and tried Dealer way---still same results.
    What is the proper torque spec and foot lbs; so I dont have to keep replacing bolts ?
    Please , any help would be Wonderful. Losing my sanity in Oklahoma . Thank-you
  • I just bought a 99 Dakota with a 3.9lt and 63,000 miles in it. The truck was not used for about a year at the time I got it. I have change the oil and filter as soon as I've got home. Couple days ago the pressure gauge hits 0 for a couple of seconds and then got back to normal. It does that twice on the same trip. Tonight it goes down to 0, never came back to normal, I was close to my house so I just got there. I turn it off, wait for a couple of minutes and start it back. The engine start to make some noice (I guess it was the lifters). Any advice from someone. Should I replace the pump and start praying?
  • dustykdustyk Posts: 2,926
    Hmmm. The older 3.9 motors and 318s required a 35 lb. torque for intake manifold. Are you sure about the 144 foot pounds?

    Regards,
    Dusty
  • dustykdustyk Posts: 2,926
    Oil pressure falling that rapidly then rising again usually indicates a clogged oil pump inlet screen. I suppose you could have a bypass valve that sticks intermittently, but I've always seen them stick in one position and stay there.

    Looks like your going to be pulling the pan anyways.

    Regards,
    Dusty

    P.S. I once found an oil pump screen blocked by a heavy paper return parts tag on a '70 Ford. That engine had 16,000 miles on it before it seize from lack of lubrication.
