Northstar engines are designed that they do not need the conventional "tune-up." They are manufactured so that spark plugs and plug wires only need replaced every 100,000 miles and the coil packs only need replaced as they malfunction. The timing on these engines also does not need to be messed with. The engine has sensors to increase or decrease timing based on the variabilites that may occur. Really, the only "tune-up" these cars need are oil changes, air filter changes and transmission fluid changes (transmission only requires new fluid every 100,000 miles). Other things you will want to keep a close eye on is the coolign system. All aluminum engines are great for power and fuel mileage, but cannot take much abuse with overheating. One case of overheating will warp the heads. Make sure to check the coolant hoses for cracks or leaks, or replace them about every 100,000 miles. It's a cheap and reliable way to ensure your engine is getting proper circulation. Also, the water pump is designed so that when it stops working, it drops fluid. This can be dangerous since the car will over heat very quickly, regardless of outside temperatures. Mine went out in the middle of January and overheated within about 30 seconds. If you need the water pump replaced take it to a mechanic that works on cooling systems. The pump housing cannot be purchased from places like Advance Auto or Napa. It comes directly from a dealer and runs about $35.00 bucks. If you replace the water pump, be smart and replace the thermostat. Hope this helps.
