Dodge Ram 2500 Problems
RepairPal has identified the most common problems with the Dodge Ram 2500 based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.
The intake manifold gaskets may leak. Coolant loss may be noticed as coolant leaks into the engine oil and/or there may be a rough idle or whistling noise. The intake gaskets need to be replaced if they are leaking coolant internally to prevent engine damage.
On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.
If a clunking or "loose lumber" noise is coming from the front or rear suspension, there are revised shock absorbers available that can help the concern. This is usually heard at lower speeds and colder temperatures when driving over bumps.
Software updates are available to solve various Check Engine Light and warning light related issues.
The throttle body may malfunction in very cold climates causing symptoms at engine start up. A throttle body causing problems will require replacement.
Engine overheating can result from coolant leaks which are commonly found at the thermostat housing gasket, water pump, heater return tube O-ring at the water pump, intake manifold gasket, and timing cover gasket. Our technicians recommend a complete inspection of the cooling system after any repairs are made to be sure there are no other leaks.
A surging or bucking during acceleration can be caused if the distributor is moved or mis-indexed. This is a result of the cam and crank position sensors being out of synchronization. Wear of the oil pump drive gear can cause similar symptoms because it allows excessive free play in the distributor drive. The distributor drive gear and bushing should be replaced if the rotor tip moves back-and-forth more than 3/16th of an inch when checking drive gear free play.
If the transmission delays initial gear engagement after being parked overnight or longer, it may be due to a suspect transmission cooler return filter. If the transmission was recently serviced and the part number for the cooler return filter contains an "AB" suffix at the end, a new filter should be installed.
