I'm replacing my oil cooler housing and wish to add an external oil cooler to it. I'm curious if it's safe to set the external oil cooler lower than the original OEM location. The OEM oil cooler works on a water/oil based. The external cooler will work air based. I'm planning to put it close to the bottom of the engine bay where fresh air will arrive from.
A few things that I thought of that could happen.
- Oil cooler lines are longer, could this lead to lower oil pressure?
- Oil cooler is lower in the engine bay, which causes the oil pump to work harder to push the oil against gravity
- Oil wouldn't be drained in the oil cooler when doing oil changes
I've added pictures with the OEM filter housing and OEM oil cooler, the new filter housing with OEM oil cooler and the new filter housing with an external oil cooler sandwich plate.
