Introducing the Z1 Motorsports 370Z Oil Cooler Kit *Customizable*

Dustin@Z1

Since we recommend that the oil cooler core be oriented with the fittings on top, a "drain valve" installed on the bottom of the oil cooler core is currently not available.

From my knowledge, no one currently offers an oil cooler core of this type either.

Here is something to consider however....Whenever you install the oil cooler kit. We HIGHLY recommend that you pre-fill the oil cooler core. This will prevent you from over filling the oil pan (compensating for the needed oil to fill the core all at once) and/or briefly dry starting the motor while the oil pump attempts to purge and fill the oil cooler core and lines.

By having a "drain valve" on the bottom of the core. You would still have to remove one of the upper fittings to fill the core back up with fresh oil. This, in my opinion, negates any benefit of having a drain valve. In reality, you would be adding another potential leak point on the core in doing so. Even with a drain valve, the time it takes to go a step further and to remove the core itself from the chassis is only a matter of x4 (4mm allen head bolts).

I would honestly see more harm than good rsulting from having a drain valve on the bottom of the oil cooler core. Especially if owners are not fully aware of the extra steps necessary to properly service the oil cooler kit.
