Kenworth T800 Coolant Reservoirs

Frequently Asked Questions About Kenworth T800 Coolant Reservoirs

Will this coolant reservoir fit my Kenworth T800?

Coolant reservoirs can vary by model year and engine configuration, so it's important to check the mounting bracket style, inlet and outlet port locations, and overall dimensions against your truck's original unit before purchasing. If you're unsure, comparing the OEM part number or providing your truck's VIN and year to our team can help confirm the correct fit.

What material are these coolant reservoirs made from?

Most coolant reservoirs for the Kenworth T800 are constructed from durable plastic designed to withstand engine heat and constant exposure to coolant. Some aftermarket options may use reinforced or heavy-duty plastic blends for added durability in demanding conditions, so check the product description for specific material details.

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

Common signs that a coolant reservoir needs replacing include visible cracks, leaks around the seams or fittings, discoloration from heat exposure, or a cap that no longer seals properly. If you notice frequent coolant loss without an obvious external leak elsewhere in the cooling system, the reservoir itself may be the culprit.

Is installation something I can do myself?

Replacing a coolant reservoir is generally a straightforward job that involves draining any remaining coolant, disconnecting the hoses and mounting hardware, and transferring them to the new reservoir. Many truck owners and shops handle this as a routine maintenance task, though if your setup includes additional sensors or level indicators, take care to reconnect them properly.

Do these reservoirs include the cap and mounting hardware?

This varies by product listing, as some coolant reservoirs are sold complete with a cap and mounting brackets while others include only the tank itself. Be sure to review the product details or reach out to our team before ordering if you need to confirm exactly what's included.
