This is the sad part. The exterior and interior are holding up so well that I would be delighted to keep this car for years to come. However, the Northstar engine has multiple design flaws. One, it's packed too tightly in the engine compartment. Makes it very expensive for any kind of service including just replacing the battery. I bought it in 2009 with 55,000 miles. No problems until last year. Had to replace wheel bearings (left and right) in front axle. Pump for air ride leveler in rear had to be replaced. This year, head valve gaskets went bad and sprayed oil onto alternator. Had to replace gaskets + alternator ($1300 in cost). Still leaks really badly from the bottom of engine. Bad design problem. Exhaust system wraps around bottom of engine and heats it up quite a bit. Causes gaskets on the bottom to break down and leak. To fix this, engine would have to be taken out. Repair would be to the tune of thousands and still no guarantee it won't happen again. This is called "the Big Leak" by some mechanics. Shame on you, Cadillac engineers. This was a stupid engine design and now I'm sitting here wondering what to do with this beautiful car body equipped with a rotten engine. BEWARE FOLKS! DO NOT BUY ANY CADILLACS WITH NORTHSTAR ENGINES! full 2002 Cadillac DeVille review |
