Engine Cooling problem
1998 Cadillac Catera 6 cyl Two Wheel Drive Automatic 76000 miles
A problem that most 98 caddi has is that the oil cooler always leaks and causes the oil and water to mix, I solved the problem by removing the oil cooler and running a new line out side. Now the oil pressure is high and goes up and down when you drive. The one reason I think is because the line is smaller. I would like to know if changing the size of the original line could be the problem or even the lenght of the line?
