Shop International 4700 - 4900 Coolant Reservoirs

International 4700-4900 Coolant Reservoirs

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

Q1: Will these coolant reservoirs fit my specific year International 4700 or 4900?

Our coolant reservoirs are designed to fit International 4700 and 4900 models from 1989 through 2003. However, there are variations between DT466 and DT530 engines, as well as differences in mounting brackets between early models (1989-1994) and later models (1995-2003). Always verify your engine type and check the mounting configuration before ordering. If you're unsure, contact our support team with your VIN number for exact fitment confirmation.

Q2: Are these reservoirs made of durable materials that won't crack like my original?

Yes, our replacement coolant reservoirs are manufactured from high-density polyethylene (HDPE) that's specifically formulated to withstand extreme temperature fluctuations and resist cracking. Unlike some OEM reservoirs that become brittle over time, these feature reinforced stress points around the mounting brackets and inlet/outlet connections. The translucent white material also allows you to easily monitor coolant levels without removing the cap.

Q3: Do I need any special tools or modifications to install these reservoirs?

Installation is straightforward and typically requires only basic hand tools - a socket set, pliers for hose clamps, and a drain pan. The reservoirs are direct replacements that use your existing mounting brackets and hose connections. Most installations take 30-45 minutes. No drilling or modifications are needed. We recommend replacing the radiator cap and hose clamps during installation for best results.

Q4: What's the difference between the economy and premium coolant reservoir options?

Our economy reservoirs meet OEM specifications and include the tank with cap. Premium reservoirs feature thicker wall construction (25% thicker than economy), upgraded brass fittings instead of plastic, and include new mounting hardware and premium hose clamps. Both options have the same capacity and fitment, but premium models typically last longer in severe-duty applications or extreme climates.

Q5: My old reservoir has a low coolant sensor - do your replacements accommodate this?

Yes, all our coolant reservoirs for 1995 and newer International 4700-4900 models include the proper port for low coolant level sensors. The sensor port is pre-threaded and sealed with a removable plug if your truck doesn't use this feature. For 1989-1994 models that didn't originally have sensors, we offer both sensor-ready and standard versions. The sensor itself is sold separately and transfers from your old reservoir.
