Question about 1997 Cadillac DeVille
The most common overheating problem with the Northstar engine is a blocked purge line(small hose).The purge line is designed to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank (not the cap) ,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.
If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.
The hose goes in to the engine to a crossover and comes out the other side close to the thermostat housing,the blockage may be there.
Can you elaborate more on the burning oil?.....how do you drive the car exactly?......do you baby it or do you floor the accelerator occasionally?........what grade of oil do you use?
The oil burning may also be a consequence of your overheating problem so check the purge line first as described above.
