Frequently Asked Questions About Freightliner Century 112/120 Coolant Reservoirs
Will this coolant reservoir fit my Freightliner Century 112 or 120?
Coolant reservoirs can vary by production year and engine configuration, so it is important to check the shape, mounting tabs, and hose fitting locations against your original unit before ordering. If you are unsure, compare the part number on your existing reservoir or reach out to our sales team with your VIN so we can confirm the correct fit for your truck.
Is this reservoir made of the same material as the original, and will it hold up over time?
Most coolant reservoirs for the Century 112/120 are made of durable plastic designed to withstand engine heat and pressure from the cooling system. Quality can vary between manufacturers, so we recommend choosing a reservoir built to OEM specifications to ensure it seals properly and resists cracking from heat cycling and vibration over the life of the truck.
How do I know if I need a new reservoir versus just a cap or hose?
If you are noticing low coolant levels, visible cracks, discoloration, or coolant leaking from the tank itself, the reservoir likely needs to be replaced. However, if the tank looks intact but you are losing coolant, the issue may be a bad cap, a loose hose connection, or a cracked fitting. Inspecting the tank closely before purchasing can save you from buying a part you do not need.
Does the reservoir come with the cap, sensor, or mounting hardware included?
This depends on the specific listing, as some reservoirs are sold as a bare tank while others include the cap, low-coolant sensor, or mounting brackets. Check the product description and included parts list on the item page, and if it is not clear, contact us before ordering so you are not left needing additional parts to complete the installation.
Is installation straightforward, or should I have a professional handle it?
Replacing a coolant reservoir is generally a straightforward job for anyone comfortable with basic maintenance, since it typically involves draining residual coolant, disconnecting hoses and the sensor if equipped, unbolting the old tank, and reversing the process with the new one. That said, always let the engine cool completely before starting work, and if you are not confident working around the cooling system, having a qualified technician handle it is a safe alternative.
