The easiest way is to pull the lower radiator hose. There is a petcock on the bottom of the radiator, but it's a pain to get to without a special tool. Pop the hose and you'll get about 85% of the coolant out. Have a large drain bucket handy. Make sure the engine is cool.

Flush coolant system on 2002 cadillac northstar engine?

DO NOT FLUSH the coolant system on a northstar. Drain the coolant, replace with 50/50 Dexcool and fresh clean water, and you're good to go. Especially NEVER NEVER buy a "Coolant Flush" at a dealer or quicky-lube place. All you'll get is the previous sucker's engine gunk pumped in to your engine.


Bleed coolant system in cadillac 4.6?

There is no need to manually bleed the coolant system on a Northstar, the system is self bleeding. The small hose on the side of the overflow tank is the self-bleed line. If, by chance, this line is obstructed, then the air will be trapped & cause overheating problems. Be careful is the plastic nipple on the side of the overflow tank as it is very weak & cracks easily.

There is no condenser on a Northstar engine - they're all a completely electronic and computer controlled ignition system. However, if you're referring to an air conditioning condenser, there will be one - it will be mounted in front of the radiator.

How do you properly bleed air pockets from 1998 Cadillac Deville 4.6l Northstar?

The Northstar cooling system is self-purging. It's highly doubtful that you have an "air pocket" but if you must do something, take the cap off the surge tank and let the engine warm to around operating temp. If there are any bubbles they'll vent from the surge tank. Then replace the cap and you're good to go. But I'd be very suprised if you have an 'air bubble'. They just don't happen on the Northstar.
