The coolant comes out the other side and into the coolant pump. Eimer Engineering fabricated a simple bracket to mount the coolant pump. The coolant leaves the pump and heads behind the radiator.
Here’s the pump outlet hose as viewed from behind the radiator. Those are the front sway bar, coolant hose, and driver-side fan for reference.
It’s not a good picture, but I have a T-fitting in there. The straight-through flow path is from the pump outlet to the intercooler inlet. The side branch goes to this Moroso tank mounted with another custom bracket. I’m using the Moroso unit as my coolant reservoir and expansion tank. It’s actually categorized as a power steering fluid reservoir. It’s all a tight fit with the intercooler coolant hoses snaking between the air conditioner and engine coolant hoses.
It’s mounted where the cruise control module used to sit. It’s very hard to see, but there’s a tiny hole under the middle ‘O’ in Moroso.
Underneath the cap, you see this fancy filter. It’s basically an air oil separator I think when the reservoir is used in its intended function as a power steering fluid reservoir. So, it lets air in and out to account for thermal expansion and contraction of the liquid in the system but it does not let the liquid out. Finding the little breather filter was a nice surprise as it isn’t mentioned in the product details. It does make me feel better about spending the money on this Moroso! There’s a nice fat o-ring on the cap for sealing too. For a simple reservoir, this Moroso unit is quite nice! The details of the cap and the rounded corners of the main body are nice design details that make the unit stand out.
