As a mechanic, I work on Deville Cadillac Northstar engines all the time; there are three in my shop now. Cadillac does have a problem with the coolant causing overheating, ultimately blowing the head gasket. This is caused lots of times by mixing antifreezes, causing the coolant to gel. I have seen this numerous times. The only repair for blown head gaskets is an engine change.
The problem with the window regulator is the nylon cable connection. The cable leaks out of the nylon bracket and the window regulator has to be replaced. On older model Caddys I have replaced lots of window motors, but very few regulators.
I have replaced probably over 50 regulators on the ones with nylon bracket, but no motors.
If you have a Caddy running good, keep it and drive your money out of it. If you need any antifreeze, please totally flush the engine coolant, and totally replace.

My advise to the person who purchased the 2000 Cadillac Deville and Cadillac engine for $2677. I think you made a big mistake!
There is no such thing as an 11 year old Cadillac Deville in excellent condition.
Having the engine installed will cost you another $1400 and up. The engine you purchased with 42,000 miles could be as bad as the one it replaced. Don't waste your money, you can do better.
I'm sorry to inform you, but the 2000-2005 Devilles are problems. Problems that came from the GM factory. You'll need lots of cash or a gold card for repairs. Most of the comments and remarks you read are true. I wish you luck. I'll never buy another Cadillac.
