Adding your products to cart

Your coolant reservoir is a critical part of your truck's cooling system. It stores excess coolant as your engine heats up and helps regulate coolant flow back into the radiator when the engine cools down. Without it, your engine can't maintain the proper operating temperature which can lead to overheating, breakdowns, or even engine damage.

Shop for Quality Replacement Coolant Reservoirs for Your 4700/4900 Truck

Our aftermarket coolant reservoirs are designed to meet or exceed OEM specifications. They're made from tough, heat-resistant materials and built to handle the high demands of commercial diesel trucks. Whether you're doing preventive maintenance or replacing a cracked tank, we've got the parts that fit your International 4700 or 4900 including replacement reservoir caps and related accessories.

What Does a Coolant Reservoir Do?

Also called an overflow tank, the coolant reservoir: - Collects expanding coolant from the radiator as engine temps rise. - Sends coolant back to the radiator as the engine cools. - Maintains proper pressure in the cooling system with the help of a reservoir cap. - Allows you to monitor coolant levels through a visible tank. In International 4700/4900 trucks, the coolant reservoir is typically located near the radiator on the passenger side under the hood mounted along the firewall or inner fender for easy access.

Signs You Need a Reservoir Replacement

Over time, coolant tanks can become brittle, cracked, or clogged with sediment. Here are a few warning signs it's time for a new one: - Visible cracks or leaks in the tank. - Coolant loss with no external leaks from hoses or the radiator. - Warning lights or frequent overheating. - Discolored or contaminated coolant inside the reservoir. - A faulty or missing reservoir cap. Ignoring these signs can lead to cooling system failure, higher repair costs, and unnecessary downtime.

Frequently Asked Questions About International 4700-4900 Coolant Reservoirs

Will this coolant reservoir fit my specific International 4700 or 4900 model year?

International 4700 and 4900 trucks were produced over many years with different cab configurations and cooling system setups, so reservoir shape, mounting points, and cap style can vary. Always check the listed year range and OEM part number cross-reference on the product page, and compare it to your existing reservoir or your truck's VIN/build sheet before ordering to confirm a proper fit.

Is this a factory OEM reservoir or an aftermarket replacement?

Our catalog includes both OEM and aftermarket coolant reservoirs. Each listing specifies whether the part is genuine International/Navistar OEM or a quality aftermarket equivalent. If matching factory fit and material composition is important to you, check the product description for OEM designation before purchasing.

What material are these coolant reservoirs made from, and how durable are they?

Most coolant reservoirs in this category are made from translucent or opaque high-density plastic designed to withstand heat cycling and pressure from the cooling system. Over time, plastic reservoirs can become brittle or develop stress cracks, especially around the neck and mounting tabs, so it's worth inspecting your old unit for these failure points when deciding whether a replacement is needed.

How do I know if my coolant reservoir needs to be replaced versus just refilled or repaired?

Common signs that indicate a reservoir needs replacing include visible cracks, coolant leaks around the seams or cap, a cap that no longer holds pressure properly, or discoloration and clouding that makes it hard to read fluid levels. If you're topping off coolant frequently without another identifiable leak source, the reservoir itself is a likely culprit.

Does the coolant reservoir come with the cap, sensor, or mounting hardware included?

This varies by listing. Some reservoirs include the cap and level sensor, while others are sold as the tank only. Check the product description and included components list carefully, and compare it to what's on your truck currently, so you're not left needing to source additional parts like the pressure cap or float sensor separately.
