Clean up the look of your engine bay and increase your engines performance with a True Focus Fabrication Combo Can! This tank bolts directly into factory mounting points so no drilling is required for mounting. The catch can features dual internal baffles with stainless mesh for superior oil separation, as well as a quick drain plug that requires no tools.  
The coolant tank features an internal tube that will allow coolant to drain once it reaches the max level, but will not leak coolant that is sloshing during spirited driving! No more scrubbing dried coolant off of your engine bay after a day at the track!

The OEM E36 motors use a coolant expansion tank, NOT an overflow tank like this product has. This tank is geared towards customers with an engine swapped E36 that already has a radiator & pressure cap already installed.

The OEM auxiliary battery terminal will need to be relocated for this tank to be installed!

This tank is not compatable with all E36 chassis! Please be sure that your car has these factory mounting holes available for the tank to bolt in. Some cars do not have them and this tank can not be installed without modifications.

Please leave a note on your order if you would like the "TFF" filter cover or coolant cap to be left raw, otherwise they will match the tank color.
