International LoneStar Coolant Reservoirs

Frequently Asked Questions About International LoneStar Coolant Reservoirs

What does the coolant reservoir do on an International LoneStar?

The coolant reservoir stores extra coolant for your engine's cooling system, allowing coolant to expand and contract as the engine heats up and cools down. It also helps keep air out of the system and makes it easy to visually check your coolant level without opening the radiator cap.

Will an aftermarket coolant reservoir fit my International LoneStar without modification?

Reservoirs listed in this category are designed to match the mounting points, hose connections, and cap style used on International LoneStar models, so they typically install as a direct replacement. Always double check your truck's model year and confirm part fitment details before ordering, since minor design changes can occur across production years.

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

Most coolant reservoirs for the LoneStar are made from durable, translucent or semi-translucent plastic designed to withstand engine heat, pressure, and constant exposure to coolant. The translucent design also makes it easy to monitor fluid levels at a glance.

How do I know if my coolant reservoir needs to be replaced?

Common signs include visible cracks, coolant leaks around the reservoir or its seams, a cap that no longer seals properly, or coolant levels that drop unexpectedly. Discoloration or brittleness in the plastic can also indicate it's time for a replacement before a leak develops.

Is replacing a coolant reservoir something I can do myself?

Yes, in most cases replacing the reservoir is a straightforward job that involves draining or relieving pressure from the cooling system, disconnecting the hoses and cap, unbolting the old reservoir, and installing the new one in its place. If you're unfamiliar with your truck's cooling system layout, consult your service manual or a qualified technician to ensure the job is done safely.
