Hello all. I am new to the Cadillac. I just bought 1988 coupe Deville. It is very clean and was well kept. I got it form a friend that needed money. But he is little help to me. He bought it and parked it because he had trouble getting the title and never really drove it. Any ways the problem I am having is that the coolant, temp, fan warning light comes on.
So I got back home and with the car running. I checked under the hood and I found that the coolant reservoir was almost full to the top and bubbling. It normally sits right at the full when hot line. I found this odd and decided to pop the radiator cap. When I did there was a rush of air and the reservoir began to overflow. I looked in the radiator and there was not much coolant in it at all. There was no steam and it did not idle rough at all. I am no mechanic, but I thought that as the fluid expands in the radiator it flow over into the reservoir. I did not think there was not enough fluid to push it out. So I turned it off. The next day I went out to check it and the coolant is down but still above the line. And the fluid in the radiator was back up about 2 to 3 inches from the top not sure what the norm is. Drove it again and about 10 to 15 min of driving the same thing happened. I am very confused and wanted to see if anyone knew what was going on with it, before I went to have it checked out. It’s a 4.5 v8 dig fuel injection. Any help would be great thanks in advance. I am not losing fluid as far as I know jus what over flowed.
