2000 Cadillac Seville SLS
My SLS is overheating, checked the belts, water levels, radiator, and thermostat has been changed and everything seems up to par, what else can I do? I'm about to bleed the air from the cooling system, should I?

The new millenium ushered in some new changes for the Cadillac Seville. First, the new model no longer required premium fuel. In addition, Cadillac adjusted the engine to minimize noise and emissions while maintaining the Seville's signature performance. Finally, new options for 2000 include a navigation system and a rear parking assist device for when you get too close to the car behind you. Otherwise, the 2000 Cadillac Seville comes in the same 2 trims: the STS and the SLS. The SLS uses a 4.6 L, 275 hp V8 engine with 4 speed automatic while the sportier STS uses a 300 hp version. Both trims have 4 doors and seat 5 while delivering 17 mpg in the city, 28 mpg on the highway. Standard features include air conditioning, power windows, power door locks, leather seats, power seats, cd player, ABS brakes, and traction control. Sunroof comes as an option. The 2000 edition showed that Cadillac could modernize its midsize sedan. Drivers have always appreciated the Cadillac Seville's smooth performance and elegant appearance. However, the same concerns remain about maintenance and durability. Only time would tell whether the Seville could fully reclaim its place atop the market.

My 2000 Cadillac Seville sts had a hole in the oil pan that I did not know about I drove it about 2 miles realized the oil light was on and dinging got out checked oil and it was empty put more in it and it still read empty looked underneath the car and it was pouring out of the oil pan drove it back home but turned it off and drifted most of the way when I did have it on it was loosing power. Got home parked it went to the store got new part put it in and now car won't start it will turn over acts like it wants to start but won't. I have looked online to try and see what could be the cause but I'm finding nothing I just hope the engine isn't ruined but I didn't drive it that far without oil in it. Please someone help me this is my only car and do not have the money to buy a new one I hope there is a fix for this.
