2001 Dodge CaravanI had a slight delay when I hit the gas at a stop light. I drive an hour to and from work. When I got close to home, I smelled rotten eggs. What can cause a rotten smell and will it last 2 week’s until I can get it fixed? There are 162,040 miles on it.


RESPONSE

The rotten smell is coming from the catalytic converter. This happens when the engine is running rich and the converter is overloaded. If driven too long the converter will melt internally and clog. Not a good idea if you can avoid it. Also the rich condition is usually accompanied with a check engine light code.  Your local auto parts store should be able to pull these codes for free. Have any issues repaired and the smell should go away shortly. Two weeks would be pushing it, but It shouldn’t leave you stranded. The fuel mileage will be horrible though.

1987 Dodge D150I have a 1987 Dodge D-150, 5.2L, automatic transmission, 2WD, and would like to know if I could put a 5.9L motor in and still have the transmission bolt up without changing it out?


RESPONSE

The blocks are the same, just the 360 is bored out to a larger displacement. So yes the transmission should bolt right up without any issue.

There is a quick way of telling the small block 318 and 360 cu. in. V8s from the 400 and 440s. On the 318 and 360s, the distributor is at the rear of the engine, while the 400 and 440 cu. in. V8s have it at the front.

2004 Dodge StratusI am trying to locate where the knock sensor is on my vehicle and what I will have to do to get to it.


RESPONSE

Knock Sensor Removal – 2.7L

The sensor screws into the cylinder block, directly below the intake manifold.

On the 2.7L engine the knock sensor is located under the intake manifold and passenger side cylinder head. The intake manifold and head will need to be removed to gain access. It is a tight fit and you will also need to use a crows foot socket to remove the knock sensor(1).

Removal – 4 Cylinder

The sensor threads into the side of the engine block in front of the starter. It is a tight fit and you will also need to use a crows foot socket to remove the knock sensor

 Installation

Install knock sensor. Tighten knock sensor to 10 N·m (7 ft. lbs.) torque. Over or under tightening effects knock sensor performance, possibly causing improper spark control.

OPERATION

When the knock sensor detects a knock in one of the cylinders, it sends an input signal to the PCM. In response, the PCM retards ignition timing for all cylinders by a scheduled amount.

Knock sensors contain a piezoelectric material which constantly vibrates and sends an input voltage (signal) to the PCM while the engine operates. As the intensity of the crystal’s vibration increases, the knock sensor output voltage also increases.

The voltage signal produced by the knock sensor increases with the amplitude of vibration. The PCM receives as an input the knock sensor voltage signal. If the signal rises above a predetermined level, the PCM will store that value in memory and retard ignition timing to reduce engine knock. If the knock sensor voltage exceeds a preset value, the PCM retards ignition timing for all cylinders. It is not a selective cylinder retard.

The PCM ignores knock sensor input during engine idle conditions. Once the engine speed exceeds a specified value, knock retard is allowed.

Knock retard uses its own short term and long term memory program.

Long term memory stores previous detonation information in its battery-backed RAM. The maximum authority that long term memory has over timing retard can be calibrated.

Short term memory is allowed to retard timing up to a preset amount under all operating conditions (as long as rpm is above the minimum rpm) except WOT. The PCM, using short term memory, can respond quickly to retard timing when engine knock is detected. Short term memory is lost any time the ignition key is turned off.

NOTE: Over or under tightening affects knock sensor performance, possibly causing improper spark control.

1987 Dodge Ram VanAll the door locks and power windows work , but the passenger door don’t work at all ,both power lock and window stopped working at the same time.

Passenger side power window and door lock stopped working at same time. All the rest of locks and power windows work???


RESPONSE

This is a common issue with older vehicles. The wiring harness becomes fragile and damages easily. Look at the wiring harness at the door jam where it flexes. This is the most common place for the wiring to become damaged.

2006 Dodge CaravanWhen I start up my 2006 Dodge Caravan SXT, it makes a whining noise. I tried driving around the block to see if it stops but the gas pedal vibrates and the noise gets louder. Not sure what is wrong. Any help would be greatly appreciated.


RESPONSE

Usually a whining noise if from a hydraulic pump. Your vehicle has two. The transmission and the power steering. Check the fluid levels on both. Of course if one of them are low take measures to refill them. Check the transmission fluid with the engine running. Check the power steering fluid with or without the engine running.

2014 Dodge AvengerThe car was in a minor fender bender a few months ago. After the car ran fine and was driven home. I’ve started it a couple times since its been sitting and it ran fine. Today I jump started it and after I removed the cables it died after a minute or less. As long as the jump cables are connected it will stay running but the gauge lights and radio will flicker. The only service light that stays on is the traction control light. I looked at as much wiring as I could for damage or shorts and didn’t find anything. I had taken the damaged headlights and grill off but otherwise haven’t done anything to repair the damaged body parts. Where should I go next?


RESPONSE

Replace the BATTERY is my first thought. Make sure the alternator belt is still on. Then check your alternators operation.  You can test battery operation. A hard impact like an accident and jumping a battery often cause damage tot he battery internally. The lead plates inside build up a crust on the plates. This crust is blasted off when a battery is jump started and the particles float to the bottom and often short out the battery.

How to test battery operation

Use a load tester to test a battery. Reading a 12v from a multi-meter does not show you anything other than its charge status. You need to test for amperage draw capabilities which can be down with a load tester.

2004 Dodge CaravanWhat is the cooler in front of my radiator in my 2004 Dodge Grand Caravan Sport? I hit a deer and am doing the repairs myself. I am able to get a partial number off the sticker on it (83403 0872A T227AD7165 ). Not sure if last letter is and A or M as its rubbed off. It is the same size as my radiator just skinnier.


RESPONSE

This would be a transmission oil cooler. Remove the radiator assembly to access the transmission cooler for removal. When replacing the transmission oil cooler, the cooler hoses must be replaced.

Inspection and Cleaning

Inspect all hoses, tubes, clamps and connections for leaks, cracks, or damage. Replace as necessary. Use only approved transmission cooler hoses that are molded to fit the space available.

Inspect external coolers for leaks, loose mounts, or damage. Replace as necessary.

2001 Dodge Ram 1500I have changed the brakes, the master cylinder, the brake booster and bled out all the brakes and still have no brakes what else can I do?


RESPONSE

Try unplugging the ABS fuse or relay and test again. If you have no brake pedal after bleeding the system there is usually a leak. It may be an external leak or internal. An internal leak may be in the master cylinder or abs control unit. An external leak should be seen by fluid spraying out and dripping to the ground. You may need to bleed the system several times to get all the air out. Of course is this is an old truck, there would be no abs system to worry with.

BLEEDING ABS BRAKE SYSTEM

ABS system bleeding requires conventional bleeding methods plus use of the DRB scan tool. The procedure involves performing a base brake bleeding, followed by use of the scan tool to cycle and bleed the HCU pump and solenoids. A second base brake bleeding procedure is then required to remove any air remaining in the system.

  1. Perform base brake bleeding.
  2. Connect scan tool to the Data Link Connector.
  3. Select ANTILOCK BRAKES, followed by MISCELLANEOUS, then ABS BRAKES. Follow the instructions displayed. When scan tool displays TEST COMPLETE, disconnect scan tool and proceed.
  4. Perform base brake bleeding a second time.
  5. Top off master cylinder fluid level and verify proper brake operation before moving vehicle.
