Brownish stuff in the radiator

Asked by Aug 11, 2017 at 03:02 PM about the 2007 Jeep Commander

Question type: General

I have brownish gunk in my radiator that looks like peanut
butter. What could possibly be the problem and is that the
reason for my air pressure light coming on after I shit the
car off and then start it back up.. The air pressure light has
been coming on since a week before my oil change.. it
has been three weeks since I changed my oil.. However,
as of yesterday the oil pressure light came on two times..
so I shut the car off and put the key in the ignition Ian's
turned the key until a few light came off and then I
pressed down on the accelerator three times.. Can
someone tell me if the reason for the gunk in the radiator
is the reason for the oil pressure light coming on?

That is oil in the coolant which means a bad head gasket. Tire pressure warnings have nothing to do with it. Better check the oil level but I think you need a mechanic!
