The Cadillac Northstar has a flawed cooling system,which causes them to run hotter than the Aluminum engine can withstand over time. When the Northstar was first introduced they still had the standard Cap on Radiator cooling system, these early model vehicles were not plaqued with overheating issues. When Cadillac switched the cooling system over to the current system with the the coolant fill tank on fender ( No Cap on Radiator ) is when all the Overheating and Head Gasket issues started!
With the old Cap on Radiator cooling system the water flows smoothly from the engine through the water pump into the radiator and back into the engine.
With the Fill Tank Design the water flows from the engine through the water pump, backwards through the radiator into the fill tank, then back into the engine. This creates many different pressure and temperature points within the cooling system causing a very unstable environment! ( Creating Hot Spots in the Heads resulting in Failed Head Gaskets )
Solution: Duplicate the environment of the Cap on Radiator system!
With the Northstar Cooling System Equalizer we have duplicated the stable environment of the Cap on radiator system by equalizing the pressure between the Engine, Radiator, and the Expansion Fill Tank.
Once installed your cooling system will function better than new, most customers see a substantial drop in operating temperature! Reducing the operating temperature and eliminating the Hot Spots in the Heads will add years to the life of your Northstar!
Another problem with the Northstar Cooling System is there is no way easy way to bleed the excess air from the system. With the Northstar Cooling System Equalizer we have solved this problem!
If You Love Your Cadillac Northstar and want to add years to the Life of the Engine
You Need the Northstar Cooling System Equalizer !
