Frequently Asked Questions About International ProStar Coolant Reservoirs

Will these coolant reservoirs fit my specific ProStar model year?

Our coolant reservoirs are designed to fit International ProStar models from 2008 to 2017. However, there are variations between early models (2008-2012) and later models (2013-2017) due to mounting bracket changes. Always verify your specific model year and engine configuration before ordering. If you're unsure, contact our support team with your VIN number for exact fitment confirmation.

What's the difference between OEM and aftermarket coolant reservoirs in terms of quality?

OEM reservoirs typically use thicker plastic construction and come with factory-grade sensors and fittings. Aftermarket options vary in quality - premium aftermarket reservoirs often match OEM specifications at a lower price point, while economy versions may use thinner plastic that can be prone to cracking after 2-3 years. We recommend checking the plastic thickness (should be at least 3mm) and verifying that all sensor ports match your original reservoir.

Do I need special tools or professional installation for replacement?

Most ProStar coolant reservoir replacements can be completed with basic hand tools in 30-45 minutes. You'll need a socket set, pliers for hose clamps, and a drain pan. The main challenges are accessing the lower mounting bolts (especially on models with air conditioning) and properly bleeding the cooling system afterward. Make sure to have at least 2 gallons of proper coolant mix on hand for refilling and system bleeding.

Why are some reservoirs significantly cheaper than others?

Price differences usually reflect material quality and included components. Budget reservoirs often come without sensors, caps, or mounting hardware, requiring you to transfer these from your old unit. Premium options include new sensors, heavy-duty caps rated for 15-20 PSI, and all mounting hardware. Check whether the reservoir includes the coolant level sensor - replacing this separately can add $40-80 to your total cost.

How can I tell if my coolant reservoir needs replacement versus just repair?

Replace your reservoir if you see stress cracks around the mounting points, discoloration from overheating, or persistent leaks at the seams. Minor issues like a bad cap or faulty sensor can be fixed individually. However, if the plastic has become brittle (common after 5-7 years), replacement is recommended as repairs are typically temporary. White residue or staining around the reservoir usually indicates slow leaks that will worsen over time.
