Engine Cooling problem
2002 Oldsmobile Silhouette 6 cyl Front Wheel Drive Automatic 126000 miles
im having a problem with my van. When I decelerate it overheats but when I accelerate mos of the time it cools down to normal and my heat comes out hot again. I dont have any antifreeze in my oil nor do I ven lose any antifreeze.I have been trying to figure it out. Got it working fine for about a week and it started doing it agani. Ive replaced the thermostat and flushed radiator. Any ideas?
