Performance Water Pump & Timing Belt Kit for Dodge Magnum (2005-2008) 3.5L

High-Reliability Water Pump & Timing Belt Kit for 2005-2008 Dodge Magnum (LX)

What it Does: The Performance Water Pump & Timing Belt Kit synchronizes camshaft and crankshaft rotation while restoring cooling efficiency on the 2005-2008 Magnum to prevent catastrophic valvetrain interference failure.

The Stock Dodge Magnum Valvetrain & Cooling Vulnerabilities

On the LX platform equipped with the 3.5L SOHC V6 (EGG engine family), the factory valvetrain utilizes an interference architecture. Over extended heat cycles, the factory timing belt stretches, cracks, and shears drive teeth. Bearing seizure in the OEM tensioner roller or weeping from the factory water pump shaft seal accelerates belt degradation by introducing coolant contamination directly behind the front timing cover. If the belt jumps timing or snaps, pistons strike open intake and exhaust valves, causing catastrophic top-end engine failure.

The Engineering Solution

This direct replacement timing kit pairs a heavy-duty, 201-tooth timing belt with an upgraded mechanical water pump and matched tensioner bearing. Constructed using oil- and heat-resistant HNBR (Hydrogenated Nitrile Butadiene Rubber) with high-tensile aramid cords, the belt resists tooth shear, dimensional stretch, and delamination under high thermal load. The water pump features an OEM-matched impeller and heavy-duty mechanical shaft seal to deliver consistent cooling flow and prevent weeping. Together with the sealed precision roller tensioner bearing, this package eliminates timing slack, dampens harmonic vibration, and protects critical valve-to-piston clearances.

What's Included

• 1 Timing Belt (201 teeth)

Frequently Asked Questions & Fitment Warnings

Does this fit the LX Magnum?

Yes, this is a direct fit for the 2005-2008 Dodge Magnum equipped with the 3.5L SOHC V6 engine. Does not fit 2.7L DOHC V6 models (chain-driven) or 5.7L / 6.1L HEMI V8 engines.

Do I need to bleed the cooling system after installing the water pump?

Yes, the 3.5L engine features a designated coolant bleeder valve near the thermostat housing that must be opened during refilling to evacuate trapped air pockets and prevent hot-spot overheating.
