If it's a regular daily driver, you'll be okay without it. Lots and lots of people running the delete with no problems. The actual engine oil cooler is in the driver's side radiator side tank. (The transmission oil cooler (if equipped) will be on the passenger’s side radiator side tank.) By removing the adapter, you're removing the connection point for the cooler lines/hoses. So, remove the adapter, remove the lines (input and output), and flush out the radiator side tank to remove the oil out of it. You can plug the radiator side tank ports or leave it open. I don't think it matters much which you decide to do as long as you have flushed the oil out of it.I assume this will delete the oil cooler? Does the oil cooler actually cool? I’ve read multiple posts saying it warms the oil/keeps temps more stable.
