Will this reservoir fit my Dodge Ram ProMaster?

Confirming fitment is the first step: this reservoir is manufactured to replace the factory part used on ProMaster 1500, 2500, and 3500 trucks produced between 2014 and 2021. Check your vehicle’s existing part number against 603-832 or 52014880AA to ensure compatibility. If the numbers match, the TEMSONE unit is intended to install using the factory mounting points and hoses.

• Compatible models: Dodge Ram ProMaster 1500, 2500, 3500 (2014–2021)

How durable is the TEMSONE coolant reservoir under engine heat and vibration?

The tank is constructed from high-quality, heat-resistant plastic formulated to resist warping and cracking under typical underhood temperatures and road vibration. Manufacturing and inspection processes aim to ensure each unit maintains structural integrity during normal service life. That reduces the risk of leaks and coolant loss associated with brittle or poorly formed reservoirs.

• Heat-resistant thermoplastic construction
• Reinforced areas at mounting points to resist stress
• Quality-tested before shipment to detect defects

Is installation difficult and what comes in the box?

Installation is straightforward for anyone familiar with basic automotive maintenance: the reservoir is supplied with a matching cap and intended to install without drilling or thermal welding. Removal of the old tank and reconnection of hoses and fasteners is generally all that’s required. For first-time installers, a basic tool set and a quick vehicle service manual check are recommended.

• Includes reservoir cap for immediate installation
• No cutting, drilling, or welding required
• Fits using original fasteners and hose connections

Does this meet or replace the factory specifications?

The unit is produced to be a direct replacement and is inspected for fit accuracy prior to shipping. Always verify the replacement part number to ensure you receive the correct variant for your vehicle.
