Performance Water Pump & Timing Belt Kit for Chrysler 300 (2005-2010) 3.5L

Heavy-Duty Water Pump & Timing Belt Kit for 2005-2010 Chrysler 300 (LX)

What it Does: The Performance Water Pump & Timing Belt Kit replaces the critical synchronization and cooling components on the 2005-2010 Chrysler 300 3.5L to protect the valvetrain from interference contact and maintain stable engine operating temperatures.

The Stock Chrysler 300 Valvetrain & Cooling Vulnerabilities

The factory 3.5L SOHC V6 is an interference engine where timing synchronization failure results in catastrophic valve-to-piston collision. Over extended thermal cycles, OEM timing belts suffer from elastomer degradation, tooth shear, and structural elongation. Compounding this risk, factory water pump bearings and internal mechanical seals deteriorate with age; shaft weep allows coolant contamination onto the belt path, which rapidly accelerates rubber rot, causes idler bearing seizure, and triggers premature timing skip.

The Engineering Solution

This service kit addresses known failure modes by pairing a high-tensile, heat-resistant timing belt with heavy-duty rotating hardware. The 201-tooth belt utilizes reinforced synthetic rubber compounds engineered to resist stretching, tooth shear, and oil degradation. The included direct-fit water pump features a precision-machined impeller to maintain peak coolant flow without cavitation, a durable ceramic seal to stop shaft weeping, and a stamped gasket. An upgraded roller tensioner bearing ensures smooth rotational dynamics under high radial loads across the entire powerband.

What's Included

• 1 Timing Belt (201 teeth)

Frequently Asked Questions & Fitment Warnings

Does this fit the LX 300?

Yes, this is a direct fit for the 2005-2010 Chrysler 300 equipped with the 3.5L SOHC V6 engine. Does not fit 2.7L V6 (timing chain) or 5.7L/6.1L HEMI V8 engines.

Should the cooling system be flushed during installation?

Yes, thoroughly flush the cooling system and refill with fresh ethylene-glycol coolant to protect the new water pump mechanical seal from abrasive particulate damage.
