Frequently Asked Questions About International S2100-S2300 Coolant Reservoirs

Will these coolant reservoirs fit my specific International S2100 or S2300 model year?

Our coolant reservoirs are designed to fit International S2100 and S2300 models from 1989 through 2017. However, there are variations between certain years. Models from 1989-2004 typically use a different mounting bracket configuration than 2005-2017 models. We recommend checking your current reservoir's part number or calling us with your VIN to ensure proper fitment. The mounting tabs and inlet/outlet positions can vary between early and late production years.

What material are these reservoirs made from, and how long can I expect them to last?

Our replacement reservoirs are manufactured from high-density polyethylene (HDPE) plastic that's specifically formulated to withstand extreme temperature fluctuations and resist cracking. Under normal operating conditions, you can expect 5-7 years of service life. The translucent white material allows for easy coolant level monitoring and is resistant to the chemicals found in modern coolants. All reservoirs include reinforced mounting brackets to prevent stress cracks that were common in original equipment versions.

Do I need any special tools or additional parts to install these reservoirs?

Installation typically requires basic hand tools including a socket set, pliers, and a drain pan. Most installations take 30-45 minutes. You'll need to drain approximately 2-3 gallons of coolant before removal. We strongly recommend replacing the radiator cap and coolant hoses at the same time, as these often show wear when the reservoir needs replacement. New mounting hardware is included with each reservoir, but you may need coolant hose clamps if yours are corroded.

What's the difference between OEM-style and aftermarket reservoirs for my truck?

OEM-style reservoirs maintain the exact dimensions and mounting points as your original equipment, ensuring perfect fit without modifications. Aftermarket universal-fit options may require bracket adjustments or additional adapters. Our OEM-style reservoirs include the correct overflow tube routing, proper sensor ports for low coolant indicators (where applicable), and match the original capacity specifications. The main advantage of our aftermarket options is cost savings, though they may require minor modifications during installation.

Why is my coolant reservoir cracking, and how can I prevent it with the new one?

Coolant reservoir cracking is commonly caused by overtightening mounting bolts, using incorrect coolant mixtures, or operating with a faulty radiator cap that allows excessive pressure buildup. To maximize the life of your new reservoir, torque mounting bolts to 8-10 ft-lbs only, maintain a 50/50 coolant mixture, and replace your radiator cap every 2-3 years. Also, ensure your cooling system is properly bled of air pockets during installation, as trapped air can cause pressure spikes that stress the reservoir walls.
