Product Description

The Cooltec Expansion Tank is a key component in your vehicle's cooling system, designed to hold excess coolant and help regulate engine temperature. This cooling water bottle is specifically engineered for certain Toyota models, ensuring reliable coolant circulation and overflow management during engine operation. Its durable plastic construction and practical design make it a direct replacement for the original part.

Fitment for this expansion tank includes select Toyota Hilux and Fortuner models equipped with 2.5 and 3.0 D4D engines from 2005 to 2017. It is essential to check your vehicle's model, year, engine size, and engine code before ordering to ensure compatibility.

Common symptoms of a failing expansion tank include coolant leaks around the tank, visible cracks or warping, low coolant levels, engine overheating, warning lights on the dashboard, and the presence of coolant odours under the bonnet. You might also notice bubbling in the tank or inconsistent heater performance.

Replace the expansion tank if you observe any signs of damage, leaks, or if the tank has become discoloured and brittle over time. Regular inspection and timely replacement help prevent more serious cooling system failures and costly engine repairs.
