Product Details

The coolant expansion tank in your vehicle gives additional fluid a place to go after expansion and contraction from temperature change. Because it is subjected to such drastic changes on a regular basis, it can often crack or break.

You want to keep all the coolant in your vehicle in the cooling system. If your tank has experienced damage such as cracking, nipples breaking off, or mounting point damage, you will need to replace it.

This replacement will fit perfectly and provide the same heating and cooling characteristics as an original unit.

When replacing, be sure to have some extra coolant. Check ECS Tuning's website for a wide variety of coolants specifically designed for your car. Most German vehicles require specialized coolant. Be sure to pick up the proper coolant when refilling to avoid damage or premature corrosion.
