Re: 91 4runner A/T oil temp light, and temp. gauge
Check that you don't have a pinhole leak in your radiator by using a pressure test kit. If the cooling system can't maintain the ~15 psi pressure (I'm guessing, don't know your truck's actual spec), then the temp will eventually creep up due to the boiling off of water and coolant. Good luck!
