2008 Dodge Ram 3500 Diesel – Water Pump Replacement

As I’ve written previously I am a big fan of the Dodge Cummins diesel pickup trucks. Replacing the water pump on this truck is another reason to love these trucks because it is such a simple service.

So much on the Cummins Diesel is great: they are very reliable, and best of all, simple to service (most of the time). If you look at this Cummins 6.7 Liter engine and compare it to a Cummins engine for a Kenworth truck they look the same, the main difference is size. Bigger Cummins industrial engines also look similar but are still larger. The company has put a lot of thought into the simplicity and serviceability of their engines. This pays off big time for the Dodge Truck owner who will experience far lower repair bills than Ford or GM diesel owners.

Our client brought this 2008 Dodge Ram 3500 Diesel truck to us with intermittent no heat in the cab and the temperature gauge going high. He had also needed to add coolant to the engine. A cooling system pressure test found the water pump leaking. Replacement was quite straight forward, and a cooling system flush was done to ensure a good concentration of clean, fresh antifreeze.

If you are looking to buy a diesel pickup truck I would strongly recommend the Dodge Cummins diesel models based on their excellent design and reliability.

2004 Dodge Ram 2500 – U-Joint Replacement

Our latest featured repair is U-Joint replacement on a 2004 Dodge Ram 2500 Pickup, brought to us by a client from Richmond, BC.

U-Joint, which is short for Universal Joint is a flexible component on a driveshaft. Driveshafts are usually found in rear wheel drive and four wheel drive vehicles. They connect the transmission or transfer case to the differential. As there is typically up and down movement between the differential and transmission a flexible coupling must be installed, and that is the universal joint.

Going back to the 1970s and earlier almost every American made car was rear wheel drive and all had driveshafts with u-joints. Nowadays this part is mostly found on trucks.

Our featured Dodge Ram 2500 was suffering from squeaking sounds and vibrations when accelerating and decelerating. Upon inspection and diagnosis we found the rear u-joint seized. On this driveshaft there are two more u-joints along with a center support bearing. These parts were still in good working order and were not replaced.

Had the owner neglected this problem the rear u-joint would have deteriorated further. The next step of wear would be loud clunks and thunks when changing gears. If left long enough the joint could break apart and this normally destroys the driveshaft adding extra costs and inconvenience.

1999 Dodge Dakota- Brakes, Steering, Tune-Up, A/C and Motorvac

Wednesday’s featured repair was performed on a 1999 Dodge Dakota pickup and includes repairs to the brakes, steering and A/C.

We performed an extensive list of repairs as this truck was taking a long journey to Montana. Prior to going, the owner wanted the vehicle inspected and repaired. The inspection revealed loose tie rod ends and pitman arm, cracked brake shoes and pads, leaking wheel cylinders, several dangerously rusted brake lines and a leaking power steering hose.

Additionally the A/C wasn’t working and the engine intermittently ran so rough that the vehicle was almost undriveable. We diagnosed and fixed these 2 concerns. Repairs consisted of an A/C low pressure cut out switch, a full ignition tune up along with a Motorvac Fuel System Service.

After repairs the vehicle ran well and was safe for the long journey ahead.

Detailed information about the Dodge Dakota can be found on this website http://en.wikipedia.org/wiki/Dodge_Dakota

Just a sample of the myriad of part replaced on this service: brake shoes, drums, wheel cylinders, metal brake lines, brake pads and rotors. Pitman arm and tie rod ends. Spark plugs, distributor cap and ignition wires. A/C cut out switch and brake hardware

Fuel Injector Replacement on Dodge Cummins Diesel

While the Cummins turbo diesel found in Dodge trucks is highly reliable an occasional concern is long engine crank over and no starting. Many times this is caused by bad fuel injectors. In this video we show you briefly what’s involved in changing fuel injectors in a 2004 Dodge truck.

The first procedure involves removing electrical connectors to the rocker arm cover, the intake tube and air heaters must be removed and then the valve cover. We can now see the rocker arms and top of the fuel injectors with their wiring connectors.

Next step is to remove the fuel lines from the transfer tubes, often a time consuming task as the transfer tubes turn with the line fitting and the transfer tube nuts must first be tightened before the line nuts can be loosened.

After the lines are removed, the transfer tubes are unbolted and pulled out.

On the bench you can see the 6 old injectors laid out.

Here are the new injectors along with cleaned transfer tubes ready for installation.

These transfer tubes are of a rather unique design and require some very special installation procedures to ensure proper sealing and avoid damage.

Here we install the injector into the cylinder head, then install the bolts and torque down the injector.

Transfer tubes are then installed, the injector nuts are then backed off and transfer tubes are torqued to spec.

Injectors are then re-torqued to proper spec and all previously removed components are reinstalled.

After reassembly it’s time to start the engine and that’s how it should sound: the start time is almost instantaneous.
