Hi guys, I am new member to this fourm. My car is k11 1995 so I lent my k11 to my family member for two months. I noticed that my temperature went on the red line when I got my k11 back. I had to check my engine coolant water so there was no coolant water in. I checked the radiator, hose pipes,, expansion tank and also oil cap. I noticed that oil cap had slightly thick oil on it. I will show pictures in a few mins. Thanks Ben.
